Twittering Litter Frog (Figures 1–4) Holotype: NMBE 1056267, adult male, from near Camp 5 (4 °08.208' N, 114 ° 53.622 ' E, ca. 114 m a.s.l.), Gunung Mulu National Park, Miri Division, Sarawak, East Malaysia (Borneo), collected 3 December 2007 by J. M. Dehling. Paratypes: BMNH 1978.1524, 1978.1525, two adult females, from Batu Pala, a limestone outlier near Camp 5, Gunung Mulu National Park, collected in 1977 by Julian M. C. Dring; NMBE 1056367–1056368, two adult males, from near Camp 5, Gunung Mulu National Park, collected 20 March 2009 by A. Haas, J. M. Dehling, Pui Y.-M., S. T. Hertwig, and A. Jankowski; KUHE 10534, an adult male, from Camp 5, Gunung Mulu National Park, collected 26 December 1989 by M. Matsui and K. Araya; SRC unnumbered (former KUHE 53678), KUHE 53676, 53679– 53681, four adult males, from near Camp 5, Gunung Mulu National Park, collected 21 August 2010 by M. Matsui, K. Nishikawa, and K. Eto. Diagnosis. We allocate the new species to the genus Leptolalax for showing the following diagnostic characters: vomerine teeth absent, finger tips rounded, fingers lacking webbing, with toe webbing basal or rudimentary, limbs relatively long and slender, subarticular tubercles indistinct, inner palmar tubercle elevated and not extending to Finger I, outer metatarsal tubercle absent, nuptial pads absent, tip of snout with vertical white bar (Dubois 1983, 1987; Lathrop et al. 1998, Delorme et al. 2006). The new species can be distinguished from all other members of the genus Leptolalax by the combination of following characters: (1) size large, SVL of males 31.8 – 34.0 mm, of females 45.5–47.7 mm; (2) snout rounded in both ventral view and lateral view; (3) interorbital distance smaller than width of upper eyelid; (4) vocal sac of males subgular, bipartite; (5) toe webbing basal; (6) skin on dorsum and dorsal side of head shagreened with tiny tubercles; (7) supratympanic fold angled; (8) pectoral glands small; (9) supraaxillary glands and ventrolateral glandular ridges absent; (10) venter spotted; (11) advertisement call consisting of long series of 8–289 notes, each composed of with three or four pulses, dominant frequency at 7225–9190 Hz, with prominent frequency modulation. Etymology. The species epithet derives from the Latin fritinniens, meaning “twittering”, in allusion to the species’ high-pitched advertisement call with prominent frequency modulation. Description of holotype. Habitus moderately slender (Figures 1 & 2); head moderately wide (HW/SVL 0.32), about as wide as long (HW/HL 0.98) and wider than trunk; snout rounded in both ventral view and lateral view, slightly protruding, its length 40 % of head length and 90 % of eye diameter, wider than long (SL/EE 0.84); canthus rostralis distinct, slightly concave between eye and nostril in dorsal view, almost straight-lined in lateral view; loreal region oblique, slightly concave; nostrils oval, directed dorsolaterally, closer to tip of snout than to eye (EN/ NS 1.12); distance between eye and nostril subequal to internarial distance (EN/NN 0.97) and much smaller than eye diameter (EN/ED 0.58); eye very large (ED/HL 0.45); pupil vertical; tympanum distinct, rounded, its diameter half the eye diameter (TD/ED 0.50); interorbital distance smaller than width of upper eyelid (IO/EW 0.65) and smaller than internarial distance (IO/NN 0.90); pineal ocellus absent; symphysial knob on anteriormost part of mandible; vomerine ridge and teeth absent; tongue large, broad, bifid, free for about half its length; median lingual process absent; vocal sac subgular, bipartite, consisting of two lateroventrally situated parts which are fused with each other medially when inflated (Figure 3); apertures of vocal sac slit-like, directed posterolaterally, situated halfway between base of tongue and corners of mouth.

Colouration in preservative. Colours generally darker; contrast reduced; pattern still distinct; iris colour faded to bluish-grey. Variation. The male paratypes are generally very similar to the holotype in size and proportions. SVL of males varies between 31.8 mm (NMBE 1056367) and 34.0 mm (NMBE 1056368). Females are considerably larger than males with an SVL of 45.5 mm (BMNH 1978.1524) and 47.7 mm (BMNH 1978.1525). Males have vocal sacs but lack nuptial pads or asperities. TFL/SVL ratio is 0.53–0.56 (males) and 0.47–0.50 (females), HW/HL 0.96–1.03 (males) and 1.13–1.14 (females), IO/EW 0.65–0.87 (males) and 0.70–0.75 (females), and EN/NN 0.97–1.08 (males) and 1.05–1.06 (females). Advertisement call. Advertisement calls of four males including the holotype were recorded and analysed (Table 1). Values are given as mean ± SD followed by range. Air temperatures during recordings ranged between 24.3 and 24.9 °C. The advertisement consisted of long series of notes (Figure 5). Number of notes within a series was 58.7 ± 36.3 (8–289). Note repetition rate was 11.7 ± 0.3 (10.6–12.8) per second. Depending on the number of notes, calls lasted 4.9 ± 2.5 (0.6–17.4) s. Individual notes lasted 34.0 ± 4.2 (14–50) ms and were separated from each other by an interval of 51.3 ± 4.7 (36–61) ms. Each note was composed of 3.3 ± 0.5 (3–4, n = 30) rather indistinct pulses (Figure 5 C). Pulse length varied considerably between 3 and 17 ms (8.8 ± 3.7, n = 37). When pulses were discrete, the interval between individual pulses was about 2 ms. Marked frequency modulation was always observed within a note. The dominant frequency at the beginning was 8266 ± 250 (7750–9200) Hz and decreased towards the end of the note to 7622 ± 154 (7250–8100) Hz. The frequency difference between the beginning and the end of the note was 650 ± 150 (200–1200) Hz. Usually, the first note or the first two notes of a series were higher in frequency (9142 ± 90 Hz, n = 129 calls from 2 males) than the subsequent ones (Figure 5 B, C). Irregular intensity modulation was observed within a single call and a note (Figure 5). Only in the recording of one male, weak harmonics were present between 9500–9800 Hz. In phases of few calls of this male, only these harmonics were audible and the corresponding notes were only about half the length of regular notes. During the recording, this male sometimes continued the vocal sac motions between two calls but no sound was audible or traceable between 20 and 44,000 Hz in the recordings. Ecological notes and distribution. The type specimens were found in alluvial forest perching on leaves in low vegetation in the vicinity of small, slow-flowing streams. All males were encountered while calling. Most specimens were found at night, but a few were heard calling between 0 930 h and 1130 h. Tadpoles of the species remain unknown. The species occurs sympatrically with Leptolalax pictus and Leptolalax cf. gracilis. Although the type series contains only specimen from Camp 5 in Gunung Mulu National Park, we are aware that the species is also distributed in Brunei and Sabah (unpublished molecular and bioacoustic data of MM and JMD). However, most voucher specimens in herpetological collections are mislabelled as either L. dringi or L. gracilis. In addition, preliminary genetic and bioacoustic analyses of specimens and their calls from several locations in Sabah (Matsui, unpubl. data; Dehling, unpubl. data) indicate that at least one further, yet unrecognized species is present. Before the relationships between the populations from Sabah have been resolved, we therefore refrain from describing the geographic range of the new species.

By the absence of both a ventrolateral glandular ridge and a supraaxillary macrogland, Leptolalax fritinniens differs from species of the genus occurring north of the Isthmus of Kra (in most parts corresponding to the subgenus Lalos Dubois, Grosjean, Ohler, Adler & Zhao, 2010), all of which have a ventrolateral glandular ridge and/or a supraaxillary gland, i.e. Leptolalax aereus Rowley, Stuart, Richards, Phimmachak & Sivongxay, 2010, L. alpinus Fei, Ye & Li, 1990, L. applebyi Rowley & Cao, 2009, L. bidoupensis Rowley, Le, Tran & Hoang, 2011, L. bourreti Dubois, 1983, L. croceus Rowley, Hoang, Le, Dau & Cao, 2010, L. eos Ohler, Wollenberg, Grosjean, Hendrix, Vences, Ziegler & Dubois, 2011, L. firthi Rowley, Hoang, Dau, Le & Cao, 2012, L. fuliginosus Matsui, 2006, L. khasiorum Das, Tron, Rangad & Hooroo, 2010, L. lateralis (Anderson, 1871), L. liui Fei & Ye, 1990, L. melanoleucus Matsui, 2006, L. melicus Rowley, Stuart, Thy & Emmett, 2010, L. nahangensis Lathrop, Murphy, Orlov & Ho, 1998, L. nyx Ohler, Wollenberg, Grosjean, Hendrix, Vences, Ziegler & Dubois, 2011, L. oshanensis (Liu, 1950), L. pelodytoides (Boulenger, 1893), L. pluvialis Ohler, Marquis, Swan & Grosjean, 2000, L. sungi Lathrop, Murphy, Orlov & Ho, 1998, L. tamdil Sengupta, Sailo, Lalremsanga, Das & Das, 2010, L. tuberosus Inger, Orlov & Darevsky, 1999, and L. ventripunctatus Fei, Ye & Li, 1990. From the species occurring on the Malay Peninsular and Borneo, L. fritinniens (characters in parentheses) differs in the following morphological characters: Leptolalax arayai Matsui, 1997 has a tuberculate dorsum (vs. smooth) without conspicuous markings (vs. present in L. fritinniens), has an unspotted, yellow venter (vs. venter white with black spots), orange groin and ventral sides of legs (vs. white to cream-coloured ventral side of legs and groin), and a single, medially arranged vocal sac in males (vs. bipartite; Figure 3). Leptolalax dringi Dubois, 1987 differs by a smaller size with SVL 26.6–31.3 mm in males and 36.6–38.1 mm in females (vs. SVL 31.8 –34.0 mm in males and 45.5–47.7 mm in females); iris bright red in upper third (vs. reddish grey); a relatively wider interorbital space with IO/EW 0.80–1.04 in males and 0.74–0.79 in females (vs. 0.65–0.87 and 0.70–0.75, respectively); angle of supratympanic fold being wider (vs. angle narrow); heads of males being wider than long with HW/HL 1.11–1.22 (vs. as long as wide HW/HL 0.96–1.03); and a relatively greater eye-to-nostril distance with EN/NN 0.81–0.90 in females and 0.76–0.89 in males (vs. 1.05–1.06 in females and 0.97–1.08 in males). Leptolalax gracilis (Günther, 1872) differs in having a curved supratympanic fold (vs. angular); a single medially arranged subgular vocal sac in males (vs. bipartite; Figure 3); relatively greater interorbital distance with IO/EW 0.78–0.99 in females and 0.71–0.89 in males (vs. 0.70–0.75 and 0.65–0.87, respectively); iris bright red in the upper two-fifths and dull greyish red, with a narrow ring of bright red along the pupil in the lower three-fifths (vs. iris dark-grey in ventral two-thirds, reddish grey in dorsal third, with inner edge around pupil ruby-red); male SVL 34.3 –39.0 (vs. 31.8 –34.0). Leptolalax hamidi Matsui, 1997 differs in having the venter unspotted (vs. spotted); large dark brown dorsal markings with light outlines (vs. dorsal markings small without light outlines); and a smaller size with SVL 28.0–31.0 mm in males, 36.0–43.0 mm in females (vs. 31.8 –34.0 mm in males and 45.5– 47.7 mm in females). Leptolalax heteropus (Boulenger, 1900) is much smaller with SVL of males 24.6 –26.0 mm and of female 31.7 mm (vs. 31.8 –34.0 mm in males and 45.5–47.7 mm in females) and has more developed toe webbing and distinct lateral fringes on the toes (vs. toe webbing basal, lateral fringes indistinct). Leptolalax kajangensis Grismer, Grismer & Youmans, 2004 has shorter legs with TFL/SVL 0.42 in males (vs. 0.53–0.56); a curved supratympanic fold (vs. angular); a black spot on the tympanum (vs. absent); an unpatterned venter (vs. venter spotted); and a dark brown dorsum with black pattern (vs. grey dorsum). Leptolalax kecil Matsui, Belabut, Ahmad & Yong, 2009 is much smaller with SVL of males 19.3–20.5 mm and female 25.0 mm (vs. 31.8 –34.0 mm in males and 45.5–47.7 mm in females), has a light brown dorsum with dark brown pattern (vs. grey dorsum with black spots); a black spot on the tympanum (vs. absent); a red iris (vs. iris dark grey in ventral two-thirds, reddish grey in dorsal third); and has large, conspicuous, orange pectoral glands (vs. pectoral glands hardly discernible). Leptolalax maurus Inger, Lakim, Biun & Yambun, 1997 is much smaller with SVL of the female holotype being 31.8 mm (vs. 43.5–47.7 mm in females) and SVL of the male paratype 26.1 mm (vs. 31.8 –34.0 mm in males), has a dark brown to black dorsal and ventral colouration (vs. grey dorsally and white with black spots ventrally); and a dark red iris (vs. dark grey in ventral two-thirds, reddish grey in dorsal third). Leptolalax pictus Malkmus, 1992 has an immaculate venter (vs. spotted) and has a light brown dorsum with dark brown markings with conspicuous thin light outlines (vs. dorsum grey with black pattern without distinct light outlines). Leptolalax platycephalus Dehling, 2012 has an immaculate venter (vs. spotted); a skin flap above the vent; a wider head with HW/SVL 0.37–0.38 (vs. 0.31–0.32); a greater interorbital distance with IO/EW 1.14–1.27 (vs. 0.65–0.87), rudimentary toe webbing (vs. basal), large pectoral glands (vs. hardly discernible), and different dorsal and ventral colouration. Leptolalax solus Matsui, 2006 is smaller with the only specimen, a male, having an SVL of 27.6 mm (vs. 31.8 –34.0 mm in males); has a larger pectoral gland; and a chocolate-brown, largely unpatterned dorsum (vs. dorsum grey with dark pattern). In addition to the morphological differences, Leptolalax fritinniens can be distinguished by its unique advertisement call from 20 of the 35 species of the genus, of which call characteristics are known (Malkmus & Riede 1993; Matsui 1997; Jiang et al. 2002; Malkmus et al. 2002; Xu et al. 2005; Matsui 2006; Matsui et al. 2009; Rowley & Cao 2009; Sukumaran et al. 2010; Rowley et al. 2010 a, 2010 b, 2010 c, 2011, 2012; Matsui & Dehling 2012). The advertisement call of L. fritinniens, as described by Matsui (1997), was compared to calls of recently described species (as L. dringi; Matsui 1997, 2006; Matsui et al. 2009; Rowley & Cao 2009; Rowley et al. 2010 a, 2010 b, 2010 c, 2011, 2012), and therefore, we compare the advertisement call only to those of the other Bornean species in the following: The call of L. fritinniens has a dominant frequency of 7250–9200 Hz at 24.3–24.9 °C. Although dominant frequency is known to vary over temperature (e.g. Rowley et al. 2010 c) the frequency of the call of L. fritinniens is likely to be higher than the dominant frequency of the calls of L. arayai (5400–5900 Hz, 17.4 °C), L. dringi (6050–6400 Hz, temperature unknown), L. gracilis (2600–2800 Hz, 20.0– 26.2 °C), L. hamidi (6700–7300 Hz, 22.9–24.1 °C), L. maurus (5150 Hz, temperature unknown), and L. pictus (6800–7150 Hz, 19–22 °C). Call length and number of notes within a call is very variable (0.6– 17.4 s, 8–289 notes), but on average (4.9 s, 59 notes), the calls recorded in L. fritinniens are longer and contain more notes than reported in the call of L. dringi (0.1 – 1.0 s, 2–11 notes), L. maurus (4.1 s, 15 notes), and L. pictus (1.9– 4.9 s, 12–31 notes). Marked frequency modulation like in the calls of L. fritinniens is absent in the calls of L. dringi, L. gracilis, and L. maurus. Note repetition rate is temperature-dependent but at 10.6–12.8 per second recorded for L. fritinniens at 24.3–24.9 °C it appears to be higher than in the advertisement calls of all other Bornean species (L. arayai 9.0– 9.3 /s; L. dringi 8.2– 10.3; L. gracilis 6.9–10.4; L. hamidi 9.0– 9.3; L. maurus 3.5) except L. pictus (11–13).Published as part of Dehling, J.

Space charge and charge trapping characteristics of cross-linked polyethylene subjected to ac electric stresses
No full textThis paper reports on the result of space charge evolution in cross-linked polyethylene (XLPE) planar samples of approximately 220 ?m thick. The space charge measurement technique used in this study is the PEA method. There are two phases to this experiment. In the first phase, the samples were subjected to dc 30 kVdc/mm and ac (sinusoidal) electric stress level of 30 kVpk/mm at frequencies of 1 Hz, 10 Hz and 50 Hz ac. In addition, ac space charge under 30 kVrms/mm and 60 kVpk/mm electric stress at 50 Hz was also investigated. The volts off results showed that the amount of charge trapped in XLPE sample under dc electric stress is significantly bigger than samples under ac stress even when the applied ac stresses are substantially higher. The second phase of the experiment involves studying the dc space charge evolution in samples that were tested under ac stress during the first phase of the experiment. Ac ageing causes positive charge to become more dominant over negative charge. It was also discovered that ac ageing creates deeper traps, particularly for negative charge. This paper also gave a brief overview of the data processing methods used to analyse space charge under ac electric stress

Leptobrachium waysepuntiense Hamidy & Matsui, 2010, sp. nov.
No full textLeptobrachium waysepuntiense sp. nov. Holotype: MZB Amp 15862, an adult female collected among the leaf litter in primary forest in Way Sepunti trail (05°03’ 51 ’’S, 104 °02’05’’E, 691 m a.s.l.; Figure 1), Kubu Perahu village, District of Liwa, Lampung Province, Sumatra, Indonesia, collected by A. Hamidy, S. Kirono, D. Susanto, Marji, Andi, and Habsi at 20:00 h on 14 February 2009 (Figures 2, 3). Paratypes: MZB Amp 14592, an adult male collected by A. Ul Hasanah and W. Endarwin from near the type locality (05°03’ 51 ’’S, 104 °02’07’’E, 852 m a.s.l.) in November 2004; KUHE 42805, a juvenile, collected on 13 February 2009, collectors and locality same as for holotype. Etymology: The specific name refers to the locality where this species was collected. Diagnosis: The new species is placed in Leptobrachium by having the combination of: femoral glands present; oval, flat axillary glands present; inner palmar tubercle circular, not extending along first metacarpal; vomerine teeth absent; snout and/or dermal palpebral projections absent; rictal glands and ventrolateral glandular ridges absent; spines on the upper lip absent. A medium-sized Leptobrachium (adult female 58.3 mm and male 50.0 mm in SVL; Table 1); iris in adult light blue with fine black reticulations, but is light grey in juvenile; dorsum uniform dark grey; dark grey laterally with white and orange dots; top of head from interorbital to parietal region, and dorsal side of fingers and toes faintly orange; greyish on belly and brownish on throat with white dots particularly on chest; no markings at groin; femoral glands very small. Species Males Females Description of Holotype (measurements in mm): Body tapering to the groin (SVL 58.3), head broad and depressed, slightly longer (HL 25.5: 43.7 % of SVL) than wide (HW 24.4: 41.9 % SVL); snout rounded from above, truncate in profile, very slightly projecting beyond lower jaw; eye large and obviously projecting from sides of head, smaller (EL 8.6: 14.8 % SVL) than snout (SL 10.5: 18.0% SVL); canthi sharp, lores oblique, moderately concave; nostrils lateral, below canthus, distinctly closer to tip of snout (S-NL 4.8: 8.2 % SVL) than to eye (N-EL 6.0: 10.3 % SVL); internarial distance (IND 4.2: 7.2 % SVL) much shorter than interorbital distance, (IOD 8.1: 13.9 % SVL), latter wider than upper eyelid (UEW 7.5: 12.9 % SVL); no pineal spot; tympanum distinct, diameter (TD 5.0: 8.6 % SVL) about three-fifth that of eye and separated from eye by half of its diameter (T-EL 2.5: 4.3 %SVL); vomerine teeth absent; tongue heart-shaped, without papillae, notched posteriorly. Forelimb slender and long (FLL 43.2: 74.1 % SVL), about three-fifths of hindlimb; fingers moderately slender, unwebbed; first finger (FFL 6.6: 11.3 % SVL) slightly longer than fourth and second, third much longer (TFL 10.3: 17.7 % SVL); tips rounded, not swollen; inner palmar tubercle large (IPTL 2.8: 4.8 % SVL), not extending onto first metacarpal and smaller outer palmar tubercle (OPTL 2.5: 4.3 % SVL); subarticular tubercles indistinct, replaced by low callous tissue. Hindlimb slender and relatively short (HLL 71.0: 121.8 % SVL); heels not meeting when legs are held at right angles to body; tibia slightly longer (TL 20.3: 34.8 % SVL) than foot (FL 19.8: 34.0% SVL); tibiotarsal articulation of adpressed limb reaching to the middle of tympanum (Table 3); third toe longer than fifth; toe tips similar to those of fingers; toe webs poorly developed, webbing formula I 2 -- 2 + II 1 + -- 3 III 2 + -- 4 - IV 4 - -- 2 V (Figure 3 C); inner metatarsal tubercle low, oval, length (IMTL 2.6: 4.5 % SVL) more than half distance between tip of first toe and tubercle (1 TOEL 4.1:7.0%); outer metatarsal tubercle absent; subarticular tubercles obscure, but elongate, replaced by low callous tissue. Skin above nearly smooth, with minute granules scattered posteriorly, especially around waist; granules denser laterally on body and on posterior thigh; ventrally slightly granular; a very low supratympanic ridge from eye to behind tympanum; indistinct low of dermal ridges on upper surface of forelimb; a flat pectoral gland at median border of axilla behind arm insertion; minute femoral gland on posterior surface of thigh. Colour: In life, dorsally dark brownish grey with a faint V-shaped brownish orange interorbital and parietal marking (Figure 3 A); grey colour fading laterally to light grey on ventral side (Figure 3 B); laterally and ventrally dotted with white and orange, especially densely on sides; white dots denser on chest and throat than on abdomen; toes orange brown dorsolaterally; iris light blue with black reticulations; light blue orbital arc surrounding iris visible when eye opened maximally; no black bars around lips; supratympanic ridge bordered by a very thin brownish orange line; forelimb dorsally vaguely barred with dark brown; posterior thigh spotted with white and orange; no dark markings around groin from posterior flank to anterior thigh. In preservative, the aspects of the colour pattern remain, but the dorsal ground colour has been darkened and orange dots have faded to white. Variation: The male paratype (MZB Amp 14592) is morphologically similar to holotype, but has smaller body, fewer dark reticulations on blue iris, more rugose dorsal skin, more distinct dark crossbars on the dorsal sides of limbs, and more distinct markings between interorbital and on upper half of tympanum. It has an internal vocal sac and a pair of vocal sac openings. The juvenile paratype (KUHE 42805; Figure 4) has a light grey iris with irregular black reticulations, and a distinct orange line from canthus through margin of upper eyelid and above tympanum to arm insertion. Narrow dark brown bars each with orange spots medially are distinct on dorsal half of limbs, and toes are dorsally light brown. Comparisons: Small number of samples limited statistical comparisons of morphometric characters, but some dimensions did not overlap between L. waysepuntiense and other species (Table 2). The new species tended to have longer LAL and FL than L. hasseltii, longer FL than L. hendricksoni, and longer LAL, FL, and IMTL than L. abbotti, all relative to SVL. In addition, the new species seemed to have larger FL/TL ratio than L. nigrops (Table 2). In the new species, the tibiotarsal articulation reached the centre of the tympanum, but it barely reached the posterior end of the tympanum in many specimens of L. gunungense, and exceeded the anterior end of the tympanum in more than half specimens of L. montanum (Table 3). More discrete differences were found in qualitative characters (Table 4). Leptobrachium waysepuntiense differs in eye colour from all the other congeneric species including the subgenus Vibrissaphora. In most species of Leptobrachium from China and Indochina like L. chapaense, L. hainanense and L. huansen (Liu et al. 1973; Yang 1991; Dubois & Ohler 1998; Lathrop et al. 1998; Fei 1999; Fei et al. 2009), L. xanthospilum Lathrop, Murphy, Orlov & Ho and L. banae Lathrop, Orlov, Murphy & Ho, as well as species of Vibrissaphora, light blue or white colour is limited to the dorsal half of the iris, unlike L. waysepuntiense with totally light blue iris. Of the Indochinese species, L. buchardi has upper part of iris pale green (Ohler et al. 2004), and L. mauhoti has black iris surrounded by an orange-red crescent dorsally (Stuart et al. 2006). Leptobrachium hendricksoni from southernmost Thailand through Peninsular Malaysia, Sumatra to Borneo (Berry 1975; our own observations), L. pullum from southern Vietnam (Smith 1921) and L. smithi from Thailand to southern Malay Peninsula (Matsui et al. 1999) share dorsal half of the iris scarlet or yellow in colour. Leptobrachium nigrops from Peninsular Malaysia, Sumatra and Borneo (Berry 1975; our own observations) and all Bornean species, L. montanum, L. abbotti (Inger et al. 1995; Malkmus et al. 2002; our own observation), and L. gunungense (Malkmus et al. 2002; our own observations) have a totally black iris. The iris of L. hasseltii from Sumatra to Bali, once reported as scarlet (Iskandar 1998), is actually totally black (our observations). In addition to the iris colour, L. waysepuntiense differs from five of the seven congeners from Sundaland as follows; Leptobrachium waysepuntiense, without distinct dorsal markings, is differentiated from L. hasseltii and L. nigrops with distinct blotches on back, and L. smithi with confluent dark markings (Matsui et al. 1999). Furthermore, L. waysepuntiense clearly differs in ventral marking from L. hendricksoni with many black spots and L. abbotti with large dark lead-grey to black spots. The remaining two species, L. montanum and L. gunungense, with totally dark iris can be easily differentiated from L. waysepuntiense with light blue iris in life, but are otherwise very similar, although femoral glands are larger and more distinct in L. montanum than L. waysepuntiense (Figure 4 B).

Known from the type locality at Way Sepunti trail, Kubu Perahu, Liwa, West Lampung, but probably also occurs in western of Jambi Province, central Sumatra (Matsui et al., unpublished data, see below) (Fig. 1). Natural history: Larval, acoustic and other ecological data are unknown. Way Sepunti trail, where the type series of L. waysepuntiense was collected, is in primary forest and located approximately 250 m from a rocky stream. On this trail, the new species was found at a higher elevation (691–852 m a.s.l.) than where L. hasseltii occurred (300 m a.s.l.). Other species found on this trail are: Leptophryne borbonica Tschudi, Megophrys nasuta (Schlegel), Kalophrynus pleurostigma Tschudi, Limnonectes kuhlii (Tschudi), Odorrana hosii (Boulenger), Hylarana crassiovis (Boulenger), Huia sumatrana Yan g, Microhyla palmipes Boulenger, M. berdmorei (Blyth), and Rhacophorus sp. Neither eggs nor larvae were found and calls were not heard in mid February.Published as part of Hamidy, Amir & Matsui, Masafumi, 2010, A new species of blue-eyed Leptobrachium (Anura: Megophryidae) from Sumatra, Indonesia, pp. 34-44 in Zootaxa 2395 on pages 36-40, DOI: 10.5281/zenodo.19395
