Liolaemus morandae sp. nov. is found in S Chubut province and Liolaemus avilae sp. nov. inhabits NW Santa Cruz province. Several tests were performed to diagnose these new species as distinct lineages. Univariate analysis of variance (ANOVA), principal component analysis (PCA), discriminant function analysis (DFA), non-parametric multivariate analysis of variance (NPMANOVA), as well as a genetic characterization through molecular analysis of variance (AMOVA) were performed; genetic distances between described and these new species are reported. The new Liolaemus species differ from other members of the lineomaculatus group in morphometric, meristic, qualitative and genetic characters; moreover they inhabit different phytogeographical provinces and districts. With these descriptions, the number of species now recognized in the lineomaculatus section is twenty one (including one more description that is in press).
查看更多>>摘要:I describe a new species of Anolis related to Anolis (or Norops) altae from Volcán Tenorio, Costa Rica. The new species differs from all other species in the A. altae complex by having the ventral surfaces of body and limbs distinctly reticulated with dark brown pigment and a male dewlap that is dark red with brown blotches, as well as in several morphometric and pholidotic characteristics. It further differs from its geographically nearest congener of this complex, A. monteverde, by having abilobate hemipenis (unilobate in A. monteverde).
查看更多>>摘要:A new species of arboreal forest viper (Serpentes: Viperidae: Athens) from a forest fragment in the Southern Highlands of Tanzania is described and named Athens matildae sp. nov. The species resembles the forest horned viper, Athens ceratophora Werner, by bearing horn-like supraciliary scales but it differs in size, body proportions, scalation, scale ultrastructure, and distribution. Genetic divergence is also assessed and the two species have an estimated divergence time of approximately 2.2 millionyears. An overview of the genus Athens in Tanzania, including new distribution data, is presented and the conservation status of the new taxon is discussed.

The new species is similar to Leporinus amblyrhynchus, L. taeniatus, L. taeniofasciatus, L geminis, L. unitaeniatus, L. vanzoi, by having a dark longitudinalmidlateral stripe and dark transversal bars on dorsum. However, the new species is distinguished from Leporinus amblyrhynchus by having four teeth on dentary (vs. three); from L. taeniatus by having 12 circumpeduncular scale series (vs. 16) and 37 to 39scales on lateral line (vs. 36 to 37); from taeniofasciatus by having 12 circumpeduncular scale series (vs. 16); from L. geminis, L. unitaeniatus and L. vanzoi by having three teeth on premaxilla (vs. four), 37 to 39 scales on lateral line (vs. 40 to 43), four or five scale series above lateral line (vs. six), and 12 circumpeduncular scale series (vs. 16). The new species is distributed in the rio Teles Pires and rio Jamanxim, rio Tapajós basin, and rio Jari, clear-water tributaries of the lower portion of the Brazilian Amazon.

This translates as: "A group dendroid in branching; almost always axially compressed, covered with very thick ectoderm, partly calcareous dotted with prominent bumps, each terminatedby a polyp".
查看更多>>摘要:The word 'name' having various meanings depending on context, in order to avoid confusion and simplify reading I here use the word nomen (plural nomina) to denote 'scientific names'. Gill & Hoese (2011) discussed the correct formation of family-groupnomina based on genus-group nomina ending in -butis, and the grammatical gender of these nomina. They have shown that the spelling Odontobutidae Hoese & Gill (1993) is correct and that its emendation into Odontobutididae by Kottelat (2001; Chen, Kottelat& Wu, 2002) was incorrect. In fact, since these last two papers, the spelling had already been discussed and the error corrected by Kottelat & Freyhof (2007, 2009), who had reached the same conclusion as did Gill & Hoese (2011), viz. Butis is not a Greek word but is based on Cheilodipterus butis Hamilton, 1822, itself based on a local (Bengali ?) name, as were the vast majority of the species-group nomina created by Hamilton (1822).
