Richards and E. Nagombi on 12 July 2016; AMS R.13302, an adult male from the Kereru Range on the Abede River, Gulf Province, Papua New Guinea (ca. 7.0280°S, 144.4226°E, elevation uncertain) by geologist J. P. de Verteuil, probably in 1947 (collection date unavailable but catalogue entry dated 6 January 1948).</p> <p> <b>Etymology.</b> The species epithet is a patronym to honour Dr. Ken Aplin (1958–2019), in recognition of his immense contributions to New Guinean herpetology, and in gratitude for his friendship and selfless collaboration with the junior author over many years. Ken’s many experiences in Melanesia have added significantly to our knowledge of the region’s vertebrate fauna, both living and fossil, and his recent passing has created a void that will be hard to fill.</p> <p> <b>Diagnosis.</b> A species of <i>Stegonotus</i> that can be diagnosed from all congeners by the following combination of characters: dorsum of body immaculate snow-white anteriorly, with dark speckling that manifests as occasional brown-tipped scales by midbody and increases in frequency and density posteriorly; tail entirely dark brown with light pigment confined to lowest dorsal scale rows; venter and subcaudal scales off-white; head dorsally dark brown, contrasting with white anterior of the body, brown pigment extending posteriorly for 6–20 scales; dorsal scales rows 17-19-15 (75%) or 19-19-15 (25%), ventral scales 229–239, subcaudal scales 83–95, all divided; SL usually nine (75%), occasionally eight (25%), with SL4–SL5 contacting the orbit; and IL nine (75%), or eight (25%) with IL1–IL4 or IL1–IL5 contacting the anterior genials.</p> <p> <b>Description of holotype.</b> (Figs. 1 A–D, 2A–B). An adult male, SVL = 1087 mm, TL = 290 mm, TTL = 1377 mm; head distinct from neck, snout rounded in dorsal view, body arch-shaped in cross-section, tail moderately long (TL 21% of TTL). Dorsal scales in 17-19-15 rows; 229 ventrals, 89 paired subcaudals, and an entire cloacal plate; SC/(V+SC) ratio = 0.28. Rostral clearly visible when viewed from above, extending back to separate internasals for one-third their depth but not to a point level with the nostrils (shallow V condition; Kaiser <i>et al.</i>, 2019). Internasals paired, in broad contact behind rostral. Prefrontals also in broad contact, twice as long and 1.3 times as wide as internasals, extending laterally onto head to contact preoculars, loreal and nasal. Frontal shield-shaped, as broad as long. Supraoculars much broader posteriorly than anteriorly. Parietals twice as long as wide. Nasal almost split by large naris, almost reaching first supralabial. Loreal rectangular, 1.5 times as long as high. Two preoculars, lower largest, nearly equal in length to loreal. Two postoculars, upper larger. Nine supralabials, SL4–SL 5 in contact with orbit, SL6–SL7 largest, SL5–SL6 contacting lower postocular. Two elongate temporals on left side (Figs. 1 C–C’, 3A), whose length when combined equals length of left parietal; upper anterior temporal contacting both postoculars, broadly bordered below by a pair of lower anterior temporals and the first of two lower posterior temporals; upper posterior temporal bordered below by two lower posterior temporals. Two elongate temporals on right side (Figs. 1 B–B’, 3B), whose length when combined equals length of right parietal; upper anterior temporal contacting both postoculars, broadly bordered below by a pair of lower anterior temporals and the first of three lower posterior temporals; upper posterior temporal bordered below by three lower posterior temporals. Infralabials nine on left side, eight on right side, with IL1–IL5 on left side and IL1–IL4 on right side in contact with the anterior genials, due to division of IL3 on the left side, and IL5–IL6 and IL4–IL5, respectively, contacting posterior genials. Mental relatively small, triangular, followed by enlarged paired IL1, which exhibit broad contact at midline. Anterior genials large and separated by mental groove, posterior genials smaller than anterior genials, also separated by the continuing mental groove. Three to four alternating chin scales separate genials from first gastrostege (ventral).</p> <p> <b>Variation.</b> All three paratypes (Figs. 2 C–H) are adult males with the following measurements: PNGNM R25322 with 1090 mm SVL + 285 mm TL = 1375 mm TTL, TL = 20.7% of TTL; SAMA R71443 with 855 mm SVL + 196 mm TL = 1051 mm TTL, TL = 18.7% of TTL; AMS R.13302 with 1180 mm SVL with a truncated tail. PNGNM R25322 and SAMA R71443 exhibit dorsal scales in 17-19-15 rows while AMS R.13302 has a dorsal scale count of 19-19-15. Ventrals and subcaudals are, respectively, 231 and 83 (SCR = 0.26) in PNGNM R25322, 232 and 95 (SCR = 0.29) in SAMA R71443, and AMS R.13302 possesses 239 ventrals but the tail is truncated at 59 subcaudals. All three specimens have nine supralabials on either side, with SL4–SL5 contacting the eye, and nine infralabials on either side, with either IL1–IL4 or IL1–IL5 contacting the anterior genials.</p> <p> There is some variation in the temporal scale arrangements in the four specimens. In the holotype the anterior and posterior upper temporals are distinct and separate, elongate scales, with the posterior scale slightly the larger (Figs. 3 A–B). The same state exists in the three paratypes but with some variation including fusion of these two scales into a single elongate upper temporal scale on the right side in PNGNM R25322 (Fig. 3D), and on the left side in SAMA R71443 (Fig. 3E). In AMS R.13302 the anterior upper temporal on the right side is almost twice the length of the posterior upper temporal (Fig. 3H), the reverse of the holotype condition, while the upper posterior temporal on the left side is divided into two scales (Fig. 3G). The lower temporal row of the holotype contains four scales on the left side, and five scales on the right side (Figs. 3 A-B). All three paratypes also exhibit either four or five scales in the lower temporal row, except PNGNM R25322 which possesses only two lower anterior temporals on the right side, the posterior-most of which comprises two scales fused to form a dumbbell shaped scale (Fig. 3D). The temporal arrangement in <i>S. aplini</i> therefore comprises an elongate upper anterior temporal that may or may not be fused with the upper posterior temporal. When the upper anterior and posterior temporals are separate the anterior temporal is in contact with three lower temporals, when it is fused with the upper posterior temporal it is contacted by three or four lower temporals.</p> <p> <b>Colouration in life.</b> The holotype and two paratypes were dorsally snow-white on the anterior and midbody regions, with infusions of black or very dark brown spots increasing in frequency from the midbody to posterior body. The dark pigment appears first on the posterior margins of the dorsal scales, gradually extending into the centres of each scale until by the tail the dorsum is primarily dark above, albeit still with large areas of white laterally. The venter is also immaculate white, with no dark pigmentation even posteriorly. The head is mid-brown dorsally, fading to light brown on the side of the head and on the neck. Although the colour in life of AMS R.13302 is unknown, its similarity in preservative to the remainder of the type series suggests a similar colouration in life.</p> <p> <b>Colouration in preservative.</b> The holotype (SAMA R71442) is creamy-white anterior-dorsally, contrasting strongly with the dark brown dorsum of the head and neck. A few scattered dark brown spots are present on this pale background by midbody, from where they rapidly increase in frequency until the posterior body is dorsally reticulate, dark brown and white, and the dorsum of the tail is almost entirely brown, although white pigment persists on the lower dorsal scale rows. The venter is near-immaculate off-white to yellow throughout. The patterning of the paratypes is almost identical, although the head of AMS R.13302 is much paler brown possibly reflecting a much longer period in preservative.</p> <p> <b>Comparison with other species.</b> <i>Stegonotus aplini</i> is a striking snake that can be immediately distinguished from all congeners with the exception of <i>S. iridis</i> by its colouration: at least the anterior third of the dorsal surfaces is snowy-white. All other congeners are unicolour grey, brown, or even black (<i>S. borneensis</i> Inger, 1967), or have white, yellow, pink or orange-red upward-pointing triangles anteriorly with a distinctly pale head laterally (<i>S. batjanensis</i>), or a reticulated pattern across the dorsum (<i>S. reticulatus</i>). Our new taxon most closely resembles <i>S. iridis</i> from the Raja Ampat Archipelago (Fig. 4), but the two species can be distinguished by the following characters (characters of <i>S. aplini</i> in parentheses): 17-19-15, 71%, or 17-17-15, 29%, dorsal scale rows (17-19-15 rows, 75%, or 19-19-15 rows, 25%); ventrals 198–211 (229–239); subcaudals 78–88 (83–95); SCR 0.28–0.31 (0.26–0.29); supralabials usually eight (86%), occasionally nine (14%) (usually nine, 75%, occasionally eight, 25%); infrabials ten, with IL1–IL5 contacting the anterior genials (usually nine, 75%, or eight, 25%, with IL1–IL4 or IL1–IL5 contacting anterior genials). The temporal scale arrangement of <i>S. aplini</i> (Figs. 3 A–H) also differs from that of <i>S. iridis</i> (Figs. 3 I–J). Both species exhibit elongate upper anterior and posterior temporals and whilst both species may occasionally exhibit fragmentation of these scales to form three upper temporals, fusion of these scales into a single elongate upper temporal, extending the entire length of the parietals, has only been observed in two of the <i>S. aplini</i> paratypes (PNGNM R25322; SAMA R71443). The lower anterior temporal in <i>S. iridis</i> is elongate, resulting in only two lower temporals contacting the upper anterior temporal, while three, occasionally four, squarish lower temporals contact the upper anterior temporal in <i>S. aplini</i>. <i>Stegonotus iridis</i> also appears to be a smaller species, with males not known to exceed 845 mm SVL (three of the four known males of <i>S. aplini</i> exceed 1000 mm SVL). A list of the major features of scalation that distinguish these two species is presented in Table 1, and a dichotomous key to the fourteen species of <i>Stegonotus</i> currently recognised on New Guinea and two additional species from adjacent areas that may occur in southern New Guinea, is provided below.</p> <p> <b>Habitat and Natural History.</b> Like other members of the genus <i>Stegonotus</i>, <i>S. aplini</i> is a nocturnal species that forages on the forest floor at night. This species was common in both primary lowland forest remote from human habitation (Fig. 5), and in garden regrowth near villages; at least ten individuals were observed during surveys of the Purari basin, where the species’ conspicuous pale colouration was readily visible in torchlight during night surveys. During capture each of the specimens struck repeatedly when handled, and attempted again to strike at researchers whilst being extracted from secure holding bags for examination. Local landowners greatly feared this species which they mistook for the highly venomous elapid <i>Micropechis ikaheca</i> 1 (Lesson, 1830), the only other pale, nocturnal snake in the region. All known locations where this species has been located are in the lowlands of the Purari River basin (Fig. 6).</p>Published as part of <i>O'Shea, Mark & Richards, Stephen J., 2021, A striking new species of Papuan groundsnake (Stegonotus: Colubridae) from southern Papua New Guinea, with a dichotomous key to the genus in New Guinea, pp. 26-42 in Zootaxa 4926 (1)</i> on pages 28-33, DOI: 10.11646/zootaxa.4926.1.2, <a href="http://zenodo.org/record/4500564">http://zenodo.org/record/4500564</a>
Stegonotus keyensis Kaiser & Kaiser & O'Shea 2018, n. comb.
No full text<i>Stegonotus keyensis</i> (Doria, 1874:351) n. comb. <p> <b>Taxonomic status.</b> <i>Lycodon keyensis</i> has heretofore been considered as a synonym of <i>S. cucullatus</i>. Based on lower ventral and subcaudal counts, a much shorter tail relative to overall body size as indicated by SCR values, and a distance of over 500 km from the type locality of <i>S. cucullatus</i> across the Bird’s Head Peninsula of West Papua and the Seram Sea, we hereby remove this species from the synonymy of <i>S. cucullatus</i>. The Kei Island populations of <i>Stegonotus</i> therefore take the name <i>Stegonotus keyensis</i> <b>n. comb.</b></p> <p> <b>Synonyms.</b> None.</p> <p> <b>Original name.</b> <i>Lycodon keyensis</i> Doria, 1874:351. The species was described by Giacomo Doria (see above), who presented the description in Italian. It is named for the Kei Islands, its geographic origin.</p> <p> <b>Holotype.</b> MSNG 7521 (Fig. 19; Table 1), most likely an adult male (see below).</p> <p> <b>Type locality.</b> “Isole Kei” [the Kei Islands, Maluku Province, Indonesia]. Just as in the case of the Aru Islands, the locality “Isole Kei” is not specific enough to determine on which of the Kei Islands the specimen was collected. A description of Beccari’s visit to these islands, supported by Beccari’s own cited letters to Doria (Gigliolo 1874), shows that Beccari spent most of his time on Dullah and Kei Kecil, after having been shipwrecked on the voyage from Aru on Kei Besar (Anonymous 2018a). It is therefore not possible to restrict the type locality further.</p> <p> <b>Collector.</b> The specimen was collected by Odoardo Beccari (see above), who arrived in the Kei Islands on 6 July 1872 and departed from the main town of Tual on Dullah for Ambon on 4 September 1872. It was therefore collected between those dates.</p> <p> <b>Key characteristics of the holotype.</b> O (651) mm SVL + 170 (164) mm TL = 800 (815) mm TTL. V ♂ = 200 (200), SC ♂ = 73 (73), SCR ♂ = O (0.27), D = O-17-O (17-17-15), SL E = 4+5 (4+5), SL = 9 (9), IL = O (9L 10R), IL G = O (5). Based on the SC count of 73 and then non-overlapping sexual dimorphism in SC numbers (see below), we believe this specimen to be a male and treat it as such.</p> <p> <b>Key characteristics of the species.</b> We were able to examine seven specimens of <i>S. keyensis</i> that were collected on one of the Kei Islands. Of these, two females were collected on Dullah, two males on Kei Besar, one male on Taam, and two (1 ♀, 1 ♂), including the male holotype, were collected at unspecified localities. Characteristics include V ♀ = 188–200 (193 ± 6.1), V ♂ = 200–207 (204 ± 3.5); SC ♀ = 59–66 (63 ± 3.5), SC ♂ = 70–80 (74 ± 5.1); SCR ♀ = 0.25, SCR ♂ = 0.27; D = 17-17-15 (100%); SL E = 4+5 (n = 6, 86%) or 3+4 (n = 1, 14%); SL = 8 (n = 5, 71%) or 9 (n = 2, 29%); IL = 8 (n = 2, 29%), 9 (n = 3, 43%), or 10 (n = 2, 29%); IL G = 5. The species shows sexual dimorphism with respect to the numbers of both ventral and subcaudal scales. This difference does not result in obviously different SCR values, but this may be a statistical artifact of comparing ratios when sample sizes are small. Roux (1910) reported on two specimens (no numbers provided), one from Dullah and the other from Kei Besar. Both of these fit within the parameters for <i>S. keyensis</i>, as reported above.</p> <p> <b>Comments.</b> The set of infralabial scales on the right side of the holotype presents one unusual feature, a fragmentation of IL9 into two small, shallow scales, each of which we counted to arrive at our count of IL = 10 L. Boulenger (1893) synonymized the species with <i>S. cucullatus</i>, but Roux (1910) considered it more likely that the synonymy should be with <i>S. modestus</i>. We have found no evidence for the occurrence of either <i>S. cucullatus</i> or <i>S. modestus</i> in the Kei Islands. The existence of the species has so far only been confirmed for Dullah and Kei Besar using voucher specimens, but it is likely that it occurs on other nearby islands as well.</p>Published as part of <i>Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Duméril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1)</i> on pages 35-36, DOI: 10.11646/zootaxa.4512.1.1, <a href="http://zenodo.org/record/2607575">http://zenodo.org/record/2607575</a>

Levels and sublevels of composition algebras over p-adic function fields
Full text linkIn [O'S], the level and sublevel of composition algebras are studied, wherein these quantities are determined for those algebras defined over local fields. In this paper, the level and sublevel of composition algebras, of dimension 4 and 8 over rational function fields over local non-dyadic fields, are determined completely in terms of the local ramification data of the algebras. The proofs are based on the "classification" of quadratic forms over such fields, as is given in [PS].Other funderRTN Network: "Algebraic K-Theory, Linear Algebraic Groups and Related Structures" (HPRN-CT-2002-00287)ke.kpw5/10/1
Credit, Consumers and The Law: After The Global Storm
No full textConsumer law, particularly consumer credit law, is characterised by increasingly complex regulation in Western economies. Reacting to the Global Financial Crisis, governments in the UK, the EU, Australia, New Zealand and the United States have adopted new laws dealing with consumer credit, responsible lending, consumer guarantees and unfair contracts. Drawing together authors from all of these jurisdictions, this book analyses and evaluates these initiatives, and makes predictions as to their likely success and possible flaws
