A New Species

A new species, Orthosinus tuberculatus Legalov, sp. nov. from Laos (Hua Phan Prov.) is described and illustrated. This new species is similar to O. foveatus Voss, 1953 from China but differs from it in the larger body sizes, the pronotum of equal length and width, wide elytral interstriae and narrow striae. It differs from other species of this genus in the wide elytra evenly rounded at the apex with rounded sides.

A New Species

Macrobrachium prabhakarani new species is described from the Vamanapuram River, Kerala, S. India. The species sharescertain characters with M. scabriculum and M. madhusoodani, while it differs remarkably from these two species in dis-tinctive diagnostic characters: rostral formula 12–14/1–2 with 5–7 postorbital teeth; carapace smooth with distal end ofrostrum directed forwards; chelae with nine denticles in the movable and six in the proximal part of the immovable finger.In larger second chelate leg, merus is longer than carpus and ischium, and propodus is the longest podomere. Carpus and ischium, equal in length and they are the shortest podomeres. Merus and dactylus are also of equal length.

A New Species

AbstractMultituberculates were among the most taxonomically diverse mammals of the early Paleocene, having survived the catastrophic Cretaceous-Paleogene mass extinction and radiating soon thereafter. Although their evolution during the early Paleocene saw the advent of increasingly specialized dentitions, multituberculates generally remained small, rarely exceeding body sizes greater than those of extant rabbits. A conspicuous exception is the Taeniolabidoidea, a primarily North American clade whose members include the largest multituberculates yet discovered. Taeniolabidoidea includes several genera, with one of these,Catopsalis, being speciose and geographically wide ranging. Until recently, the chronological succession ofCatopsalisappeared to document a trend of increasing body size. We report here on a new species ofCatopsalisfrom the early Paleocene of Alberta that violates this trend and suggests that the evolutionary history ofCatopsalisis considerably more complex.Catopsalis kakwanew species is not only the smallest species ofCatopsalis, but is the smallest taeniolabidoid so far discovered, with an estimated body mass between 400 g and 660 g. In contrast to previous studies, we used recently proposed regressions based on lower cheek tooth row length to estimate body masses for North American taeniolabidoids. Our results propose more modest body mass estimates, particularly for the largest taeniolabidoids. The occurrence ofC.kakwan. sp. in the late early Paleocene implies either a significant ghost lineage, or reversal of several characters, including body size, during the latter part of the early Paleocene; the more likely of these scenarios must await a better understanding of the phylogenetic position ofC.kakwan. sp.UUID:http://zoobank.org/66d85345-49b8-4a46-ba6e-a4d4369cb3e0urn:lsid:zoobank.org:pub:AF7A5659-9068-4F2F-A6EC-5522A2BBA4CB

A New Species

A new species of Trachycorystes from the rio Aripuanã, above Dardanelos and Andorinhas falls, is described. The new species is distinguished from the only other species of the genus, T. trachycorystes, by the following characteristics: jaws of equal length (vs. lower jaw prognathous in T. trachycorystes); skull roof covered by thick (vs. thin) integument; inner mental barbel very thin and short not reaching base of outer barbel (vs. extending to or beyond base of outer mental barbel); dorsal-fin spine serrated posteriorly, smooth or rough anteriorly (vs. serrated anteriorly and smooth or rough posteriorly); caudal fin shallowly forked (vs. emarginate); and gas bladder simple, without diverticula (vs. with three posterior diverticula). Comments and data on the nominal species Trachycorystes trachycorystes are provided. Trachycorystes cratensis Miranda Ribeiro, 1937, is allocated to the genus Trachelyopterus Valenciennes, 1840, and another local catfish species, Parotocinclus aripuanensis Garavello, 1988, has its type locality reassigned.

A New Species

Kryptopterus platypogon, a new species of silurid catfish is described from the Rajang River drainage in northern Borneo. Kryptopterus platypogon, together with K. hexapterus and K. cheveyi, can be distinguished from congeners by a combination of the absence of the dorsal fin, a stronglyarched dorsal profile with a pronounced nuchal concavity and palatal teeth in a single elliptical patch. Kryptopterus platypogon differs from K. hexapterus in having a more strongly-projecting lower jaw, larger eye (14.1% HL vs. 8.0 12.6), longer maxillary (135.6% HL vs. 40.0 120.4) and mandibular (119.3% HL vs. 32.3 80.0) barbels that are flattened and ribbon-like (vs. flattened, but ovoid in cross section), and more ventrally-placed eyes (about one quarter of the orbital margin visible when the head is viewed ventrally vs. orbital margin barely visible), and from K. cheveyi in having a strongly projecting lower jaw (vs. upper and lower jaws of equal length), more anal-fin rays (83 vs. 66 71), narrower head (8.6% SL vs. 9.7 12.3) and smaller eye (14.1% HL vs. 18.9 22.7).

A new species of boreopterid pterosaur from the new fossil locality, Heichengzi, Beipiao, western Liaoning, China allows a reassessment of the Boreopteridae. In this new analysis, three species, Boreopterus cuiae, Boreopterus giganticus n. sp., and Zhenyuanopterus longirostris, are included within the Boreopteridae united by the autopomorphic occurrence of two main tooth morphologies, an equal length of the tibia and femur, and weak feet. Other taxa previously placed within the Boreopteridae are not in a monophyletic group with the former three species. Boreopterus has fewer teeth and a shorter tooth row than that in Zhenyuanopterus. This new Boreopterus species has a large size, a piriform orbit, an extensively fenestrated lacrimal, and a posteriorly directed lacrimal process, that differs from Boreopterus cuiae.

The Afrotropical genus Eurypeza Lacroix, 2006 (Coleoptera: Scarabaeidae: Melolonthinae: Tanyproctini) was established for one species, Eurypeza evansi Lacroix, 2006, from Somalia. The genus belongs to the first group of Afrotropical Tanyproctini sensu Lacroix (2007), and is characterized by protarsomeres 1–4 and mesotarsomeres 1–4 broadened and ventrally macrosetaceous, protarsomere 5 and mesotarsomere 5 simple, and labrum transverse and shallowly bilobed. The genus Eurypeza differs from other genera of Lacroix’s (2007) first group by club with five antennomeres, antennomere 3 and 4 of equal length, labial palpi with three palpomeres, clypeus broadly rounded, protibia bidentate with proximal tooth well developed, and metatibial carina incomplete (for details, see also Lacroix 2006, 2007).
