Acanthonus armatus Günther, 1878 is reported for the first time in the southwestern Caribbean region, off Colombia. Remote Operate Vehicle videos and towed camera still photographs captured 13 images of A. armatus between 2215 and 2564 m. These are the first records of the species in the Caribbean continental coast of Colombia, representing a range extension to the southwestern Caribbean region, since previous records are from the northeastern Caribbean. Some photos of the specimens and the current distribution of the species in the Caribbean region are provided and reviewed.

Abstract: We report range extensions for three species of Amazonian erethizontids, Coendou bicolor, C. ichillus, and C. nycthemera. We record C. ichillus for the first time in Brazil, from Rio Japurá, state of Amazonas. We record C. bicolor for the first time in the state of Amazonas, which represents a range extension of approximately 905 km. We also extend the occurrence of C. nycthemera 620 km to the south into Mato Grosso state. All records are based on museum specimens, highlighting the importance of scientific collections as biodiversity databases and emphasizing the lack of research on Amazonian porcupines.

The New Zealand mudsnail Potamopyrgus antipodarum (Gray, 1843) has been considered as one of the most invasive mollusks worldwide and recently was listed among the 50 most damaging species in Europe. In the present paper, we report for the first time the presence of P. antipodarum in the Maule river basin, Chile. The identity of the species was based on anatomical microdissections, scanning electron microscopy comparisons, and DNA barcode analysis. This finding constitutes the southernmost record of the species until now in this country and South America.

The taxonomy of the hylicine genus Hatigoria Distant is reviewed based on morphological study of the types and other specimens. The male external morphology and genitalia of two known species, H. praeiens Distant, 1908 and H. sauteri Jacobi, 1914, are described and photographed for the first time. A description and figures of the female ovipositor of H. praeiens Distant, 1908 are provided. One new species, H. longistylia n. sp., from Laos and China is reported with descriptions and figures. This also represents the first record of the genus Hatigoria from Laos. A key to adult males of all species is provided.

The genus Xenoxybelis contains two species, X. argenteus and X. boulengeri, characterized by semi-arboreal habits and an extremely thin rostral area, classified in the subfamily Xenodontinae (Colubridae). Xenoxybelis boulengeri is considered a rare species and is poorly represented in scientific collections. Its external morphology is known only from the original description and seven other specimens. In this study, twenty additional specimens were examined from the Brazilian states of Acre, Amazonas and Rondônia. Variation in meristic and morphometric characters are described, and new characters are incorporated in a revised diagnosis of the species. Illustrations and a description of the hemipenes of X. boulengeri are presented for the first time. Analysis of morphological and molecular characters permit allocation of Xenoxybelis to the tribe Phylodryadini, together with Ditaxodon, Philodryas, Pseudablabes and Tropidodryas.

Titanochrysa Sosa & Freitas is a new genus of Neotropical Chrysopini (Chrysopidae: Chrysopinae) recorded from Costa Rica,Venezuela and Brazil. Titanochrysa gen. nov. shares several external and genitalic characters with Ceraeochrysa Adams, 1982;Chrysopodes Navás, 1913; Cryptochrysa Freitas & Penny, 2000; Parachrysopiella Brooks & Barnard, 1990 and Ungla Navás1914. It may be distinguished from those genera by its very long sternite 8+9, sternites 2–8 usually with microtholi, male geni-talia with the dorsal surface of the arcessus striated, gonosaccus well-developed, bearing elongate gonosetae and microsetae,and a spoon-like gonapsis. Herein, Titanochrysa circumfusa (Burmeister, 1939) [= Chrysopodes circumfusa (Burmeister)]comb. nov. and Titanochrysa pseudovaricosa (Penny) [= Ceraeochrysa pseudovaricosa Penny, 1998] comb. nov. were identi-fied; Titanochrysa ferreirai Sosa & Freitas sp. nov. and Titanochrysa trespuntensis Sosa & Freitas sp. nov. were described.The external morphology, and male and female genitalia of all these species are described. Titanochrysa circumfusa (Burmeister, 1939) comb. nov. is recorded for the first time from Venezuela.

The occurrence of the bignose shark Carcharhinus altimus at Ducie Island, Pitcairn Islands is reported for the first time based upon re-identification of four museum voucher specimens. The presence of a pregnant female and a juvenile confirms C. altimus breeds at Ducie Island and should be considered resident there. The specimens had been misidentified as the grey reef shark, C. amblyrhynchos, emphasising the ongoing value of collecting museum voucher specimens of supposedly common species. The occurrence of C. altimus at Ducie Island suggests resident populations of C. altimus are likely to occur throughout the tropical and subtropical Pacific Ocean but may have been overlooked due to their preference for deep demersal habitats during the day, or misidentification as other Carcharhinus species.  

Systematic and taxomonic revaluation of four little known Asian agamid species, Calotes kingdonwardi Smith, 1935, Japalura kaulbacki Smith, 1937, Salea kakhienensis Anderson, 1879 and the monotypic genus Mictopholis Smith, 1935 (Reptilia: Agamidae)

Subjective Synonym

The systematic status of many Asian Draconine agamids has long been in dispute. Herein, four such species, Mictopholis austeniana, Japalura kaulbacki, Calotes kingdonwardi and Salea kakhienensis are examined on the basis of external morphological characters. The monotypic genus Mictopholis was compared to other Asian Draconine genera and found to be indistinguishable from Pseudocalotes, with which it is here considered a synonym. Japalura kaulbacki is compared to other members of the genus Japalura as well as other similar species. Based on external morphology it is found to be separable from Japalura and conspecific with Calotes kingdonwardi, under which it is considered a junior subjective synonym. Salea kakhienensis is redefined morphologically based on nontype material and shown to represent a close member of this group. C. kingdonwardi is most similar to Salea kakhienensis both of which share a complement of characters with M. austeniana. The generic placement of S. kakhienensis relative to Salea, both with strongly overlapping synapomorphic characters is briefly discussed with respect to biogeographical implications that strongly support the exclusion of this species from the genus. Mictopholis austeniana, Calotes kingdonwardi and Salea kakhienensis are redescribed in detail and transferred to Pseudocalotes. The inclusion of these three species provides a generic range extension of approximately 800 km north-west of the previously considered range. The nomen Oriocalotes discolor is considered a primary objective synonym of Pseudocalotes kakhienensis new comb. and the systematic status of Calotes kingdonwardi bapoensis is briefly discussed.
