Siamaxonopsis Smit 2016, n. gen.
No full textGenus Siamaxonopsis n. gen. Diagnosis — Dorsal and ventral shields present. Dorsal shield fused anteriorly with ventral shield. Dorsal shield with A2, postocularia and four pairs of glandularia, the most posterior pair flanking the excretory pore (the latter fused with dorsal shield) and visible only in posteromedial view. Anterior coxal plates not extending to anterior idiosoma margin, without hook-like structures. Anterior to fourth leg sockets a ridge extending to lateral idiosoma margin. Between fourth leg sockets and genital field with two pairs of glandularia, lying closer to genital field than to fourth leg sockets. Genital field numerous pairs of acetabula. P2 with a large nose-shaped extension. Type species — Siamaxonopsis ypsilon n. sp. Remarks — The only known axonopsine genus with more than three or four pairs of acetabula is Omanaxonopsis Smit and Peši´c, 2010. However, this genus has one pair of glandularia between the fourth leg sockets and the genital field, has no dorsal glandularia flanking the excretory pore, has a truncate lateral projection of the ventral shield and leg claws with dorsal and ventral clawlets (Smit and Peši´c 2010).Published as part of Smit, H., 2016, The water mite family Aturidae Thor, 1900 from Southeast Asia (Acari: Hydrachnidia) with the description of one new genus and 14 new species, pp. 341-365 in Acarologia 56 (3) on page 360, DOI: 10.1051/acarologia/20162248, http://zenodo.org/record/539384

Arrenurus (Micruracarus) pesici Smit, 2010, n. sp.
No full textArrenurus (Micruracarus) pesici n. sp. (Figs. 13 A–C) Material examined. Holotype male, Little Llangothlin Nature Reserve, New South Wales, Australia, 30 ° 0 5.104 S 151 ° 46.564 E, alt. 1353 m a.s.l., 21 November 2003 (AMS). Diagnosis. Cauda not set off from remainder of idiosoma, cauda posteriorly with a shallow indentation. Description. Male: Idiosoma yellowish brown, 796 long and 680 wide. Dorsal shield incomplete, holotype also lacking lateral part of dorsal furrow, which must be considered as an anomaly. Width of dorsal shield therefore not measurable. Cauda not set off from remainder of idiosoma, posteriorly with a shallow indentation, inner margins of cauda with small irregularly shaped hyaline membranes (Fig. 13 A). Petiole hyaline, irregularly fork-shaped, left fork a little longer than right fork, attached to idiosoma by a hyaline membrane. Medial distance of third and fourth coxal plates relatively wide. Genital plates long, almost extending to lateral idiosoma margin, slightly sloping (Fig. 13 B). Lengths of PI-PV: 30, 68, 46, 92, 56; PII medially with five setae, three anteriorly, one more dorsally and more posteroventrally (Fig. 13 C). Antagonistic bristle of normal size, but looks short in illustration due to its position is slide. Lengths of I-leg- 4-6: 126, 118, 146. Lengths of IV-leg- 4-6: 150, 150, 156; IV-leg- 4 without spur. Third and fourth legs with numerous swimming setae. Female: Unknown. Etymology. Named after Dr. V. Pešić in appreciation of his acarological work. Remarks. The new species belongs to a group of water species with a hyaline fork-shaped petiole. In all other species (A. forpicatoides, A. perplexus Smit and A. queenslandicus Smit) the indentation of the cauda is narrow and deep.Published as part of Smit, Harry, 2010, Australian Arrenurus (Acari, Hydrachnidia) with the description of eleven new species, pp. 1-26 in Zootaxa 2541 on pages 19-20, DOI: 10.5281/zenodo.19669

No full textTorrenticola calliope n. sp. Synonymy. Torrenticola harrisoni K. Viets, 1956 sensu Motas & Tanasachi 1968: p. 175, figs. 4–6); Goldschmidt & Smit (2009: p. 191, fig. 5). Type material. Holotype male (RMNH: ZMA. ACAR. 32333), Ethiopia, Roby River, 9 º 44.996 N, 38 º 59.743 E, alt. 2507 m asl., 21.x. 2006, Smit; described and illustrated by Goldschmidt & Smit (2009) in fig. 5, dissected and slide mounted. Paratype (RMNH): 1 /0/0, same data as holotype, unmounted. Diagnosis. Cxgl- 4 far posterior at margin of Cx-I/II between I-L and II-L insertions, but approaching to I-L insertion; P- 2 and P- 3 with a subrectangular, apically serrated distoventral projection, moderately long ventral seta laterally at base of ventrodistal protrusion of P- 2, ventrodistal protrusion P- 4 stout with well developed ventral protuberance in distal half of segment. Description. Male as described by Goldschmidt & Smit (2009) from Ethiopia, and illustrated in their figure 5 as Torrenticola harrisoni K. Viets, 1956. Female as described and illustrated Motas & Tanasachi (1968) from River Takazé, Ethiopia, and illustrated in their figures 4–6 as Torrenticola harrisoni K. Viets, 1956. General features —Cxgl– 4 far posterior at margin of Cx-I/II between I-I and II-L insertions, but approaching I- L insertion; ventral margin of gnathosoma moderately curved, rostrum well developed and slender (see Fig. 5 B in Goldschmidt & Smit 2009); P- 2 shorter than P- 4, P- 2 ventral margin convex, moderately long ventral seta (longer than length of P- 2 ventral projection) laterally at base of ventrodistal protrusion of P- 2, P- 2 and P- 3 with a subrectangular, apically serrated distoventral projection, P- 4 with well developed ventral protuberance just in distal half of segment (see Figs. 5 B–C in Goldschmidt & Smit 2009). Male: medial suture line of Cx-II+III moderately long; ejaculatory complex with small proximal chamber (see Fig. 5 B in Goldschmidt & Smit 2009). Female: genital field pentagonal (see Fig. 4 in Motas & Tanasachi 1968). Etymology. The species is named after Calliope (Ancient Greek: Καλλιόπη), one of nine Muses from Greek mythology, who was a patron of epic poetry and song. The species name is a noun in apposition (in the nominative case), despite the Recommendation 31 A of the ICZN (1999) about avoidance of personal names as nouns in appositions, because there is no case for it being confusing or misleading. Discussion. Goldschmidt & Smit (2009) were aware that specimens from Ethiopia assigned to Torrenticola harrisoni, those described Motas & Tanasachi (1968) and their two males differ from the type specimen described by K.Viets (1956) from South Africa. Moreover, they mentioned that their specimens differ from those described by K. Viets (1956) as well as by Motas & Tanasachi (1968) in having a longer and slender ventrodistal protrusion of P- 2, a relatively shorter P- 2 and a relatively longer P- 4. Goldschmidt & Smit (2009) mentioned that the ventral seta on P- 2 of their specimen is longer than in the figure given by Motas & Tanasachi (1968), however, they considered that to be a case of intraspecific variability. In the light of newly discovered findings of Torrenticola harrisoni in Ghana, these morphological differences cannot be attributed to intraspecific variability. The specimens from Ethiopia described by Goldschmidt & Smit (2009) as well the specimens described by Motas & Tanasachi (1968) differ from the orginal description of T. harrisoni and specimens from our study in having a moderately long ventral seta laterally at the base of the ventrodistal protrusion of P- 2. In the figures given by K. Viets (1956) and K.O. Viets (1965) this seta is completely missing. In specimens in our study this seta is very short, denticle-like and inserted closely at distal edge of P- 2 ventrodistal protrusion (see Figs. 8 A–C, 10 B–C). This seta is hardly visible and sometimes not exceeding the serrate distal edge of the ventrodistal protrusion, so it is possible that it has been overlooked in the description of South African specimens. In our opinion the Ethiopian populations reported by Goldschmidt & Smit (2009) and Motas & Tanasachi (1968) differ from populations from South Africa and Ghana, and warrant the erection of a new species, Torrenticola calliope n. sp. Distribution.

Cymothoa hermani Hadfield, Bruce & Smit 2011
No full textCymothoa hermani Hadfield, Bruce & Smit, 2011 Cymothoa hermani Hadfield, Bruce & Smit, 2011: 57 –68. Remarks. Cymothoa hermani can be identified by the unique bulbous ornamentation on pereonite 1, anterolateral angles on pereonite 1 rounded and produced past frontal margin of cephalon, long and slender dactyli and the numerous lobes on pleopods 4 and 5 in the ovigerous female. The only other Cymothoa species known from the region, C. eremita, differs from C. hermani by the lack of the characteristic bulbous ornamentation on pereonite 1 that is present in C. hermani. Cymothoa eremita also has a dorsally visible and wider cephalon with the anterolateral margin of pereonite 1 not produced past the cephalon; irregular posterior margins of the pleonites with pleonite 5 appearing to have very distinctly produced sub-medial points; and more acutely produced lateral pereonite margins than in C. hermani. Hosts. Only known from Leptoscarus vaigiensis (Quoy & Gaimard, 1824) (see Hadfield et al. 2011). Distribution. Known from the type location, off Miwi Island, Zanzibar, Tanzania (Hadfield et al. 2011).Published as part of Hadfield, Kerry A., Bruce, Niel L. & Smit, Nico J., 2013, Review of the fish-parasitic genus Cymothoa Fabricius, 1793 (Isopoda, Cymothoidae, Crustacea) from the southwestern Indian Ocean, including a new species from South Africa, pp. 152-176 in Zootaxa 3640 (2) on pages 163-164, DOI: 10.11646/zootaxa.3640.2.2, http://zenodo.org/record/21957

Diagnosis — Eyes absent, venter with distinctive longitudinal ridges. Description — Female: Idiosoma brown coloured, dorsally 489 long and 373 wide, ventrally 467 long; eyes absent. Dorsal shield fused anteriorly with ventral shield, 373 wide; excretory pore fused with dorsal shield. Dorsal shield with A2, postocularia and four pairs of glandularia; due to rugosity of integument associated setae of dorsoglandularia not visible. Body pores of integument arranged in a rounded pattern in anterior part of dorsal shield; anterior part of dorsum with two pairs of large lateral papillae. Anterior coxae not extending to anterior idiosoma margin. Coxal suture lines obliterated. Apodemes of gnathosoma very long. Anterior to the fourth leg sockets a ridge extending to the lateral idiosoma margin. Venter with numerous distinctive longitudinal ridges. Between fourth leg sockets and genital field two pairs of glandularia, lying close to each other. Genital field with three pairs of acetabula; gonopore 60 long and 46 wide. Length of P1-5: 30, 50, 24, 50, 53. P4 stocky and ventrally somewhat bulging, with a long ventral seta; P5 long and slender. Length of I-leg-4-6: 52, 54, 56 (till tip of segment). Length of IV-leg-4-6: 80, 78, 56. Numbers of swimming setae: IV-leg-4 one, IV-leg-5 two. Male: Unknown. Etymology — Named for the distinctive ridges of the venter. Remarks — The combination of absence of eyes and the presence of longitudinal ridges is characteristic for the new species. Vicinaxonopsis caeca (Smit and Peši´c, 2014) from Borneo has reduced lateral eyes and a different patterns of the anterior dorsal shield (Smit and Peši´c 2014). Despite the absence of eyes, the distinctive brown colour of the idiosoma shows that this species is not hyporheic.Published as part of Smit, H., 2016, The water mite family Aturidae Thor, 1900 from Southeast Asia (Acari: Hydrachnidia) with the description of one new genus and 14 new species, pp. 341-365 in Acarologia 56 (3) on pages 362-364, DOI: 10.1051/acarologia/20162248, http://zenodo.org/record/539384

Named after its similarity with T. indica. Discussion. The specimens from Borneo agree well in general morphology of the palp (P-2 and -3 with a subrectangular, anteriorly directed and apically serrated hyaline extensions) with Torrenticola indica Cook, 1967, a species described from India (Cook 1967). The latter species can be easily distinguished in a different colour pattern on the dorsal shield (see Cook 1967: fig. 222) and in the male having a longer medial suture line of CxII+III. Wiles (1999) reported T. indica from several sites in the catchment area of the Rivers Temburong and Belalong in Brunei Darussalem, without discussion on differences with the original description. Habitat. Sandy/bouldery streams, shaded by rain forest (Figs. 43A, C). Distribution.
