Both species are assigned to the Cnemidophorus ocellifer group and are distinguished from all other congeners on the basis of lepidosis and color pattern. One of them, Cnemidophorus cyanurus, shares with the species of the subgroup of C. littoralis (C. abaetensis, C. littoralis and C. venetacaudus), a bluish green tail, spurs on the heels of males, 6-7 supraciliaries, a high number of femoral pores (27-45), a row of enlarged scales in the dorsal part of the humerus, and 8 to 10 rows of ventral scales. The second species, Cnemidophorus nigrigula, shares with the C. ocellifer subgroup (composed of C. ocellifer, C. mumbuca, C. jalapensis and C. confusionibus) a low number of femoral pores (14-21), enlarged scales in the temporal region posterior to the third subocular, 5 supraciliaries, 6 to 8 rows of ventral scales, and a brown tail color. It is also characterized by males being conspicuously larger than females and by females retaining the juvenile color pattern, which is lost in adult males. The latter characteristic has not been reported in any species of the C. ocellifer group before now. The two newspecies occur sympatrically at Santo Inacio.
查看更多>>摘要：The genus Soesilarishius Makhan, 2007 is revised: a diagnosis and a redescription are proposed based on the type species, seven new species from northeastern Brazil and Soesilarishius aurifrons (Taczanowski, 1878) comb. nov. from Peru. The previously monotypic genus contains now 9 species and is characterized by the reduced spiraled embolus. The species S. minimus sp. nov., S. lunatus sp. nov., S. cymbialis sp. nov. and S. dromedarius sp. nov. are described based on specimens from the State of Pernambuco, while S. crispiventer sp. nov., S. spinipes sp. nov. and S. albipes sp. nov. are based on specimens from the State of Bahia. In addition, the type series of Euophrys aurifrons Taczanowski, 1878 from Peru is revised, a lectotype is designated and the male palp is illustrated for the first time.

These forest dwelling lizards are famous for their cryptic and odd appearance. We describe a new species of the Uroplatus ebenauigroup from the Montagne d'Ambre massif in northern Madagascar. Uroplatus finiavana sp. nov., is morphologically similar to the sympatric U. ebenaui but differs in multiple character state expressions, among which are a longer tail and an unpigmentated oral mucosa. It also can be differentiated from U. ebenaui and all other Uroplatus species based on a high level of divergence in the mitochondrial ND4 gene and the nuclear C-mos gene, and no instances of haplotype sharing exist in these genes among the analysed species. The new species is relatively abundant at Montagne dAmbre National Park where at lower elevations (ca. 700 m) it occurs together with U. ebenaui, without any signal of genetic admixture. Records of U. ebenaui in the mountains and forestblocks of northern Madagascar (especially in the Tsaratanana massif) actually represent other candidate species with distinct morphology and characterized by a high genetic divergence from the described species. Beside the description of the new specieswe discuss the geographic provenance of the holotypes of the nominal species and synonyms in the U. ebenaui group and provide further information on the phylogeny of the U. ebenaui species group including the first incorporation of Uroplatus malama in amolecular data set.

Characteristics of the new species include a lip region separated from the rest of body by a sharp constriction, 1.1-1.3 mm long body, 10-11 um long odontostyle dorsal line and 8-10 um long odontostyle ventral line, 15-16 urn long arcuate odontophore, anterior uterine sac 37-61 um long (1.1-1.7 times corresponding body width), female tail straight to ventrally bent, elongate conoid with rounded terminus and 46-62 um long and males with 31-35 um long spicules, 5-6 ventromedian supplements and ventrally bent tail, 39-60 um long. An updated identification key to all the valid species of Dorylaimoides, as well as a table of data for the species not included in the study by Pena Santiago and Peralta (1997b) is given.
