Distribution | Argentina (Rio Negro) Type locality: rocky outcrops (1000 m asl) of Cari Laufquen basaltic Tableland in Abi-Saad farm (41°02'12"S, 70°24'30.6"W), adjacent to Provincial Road 6, 61 km north of Ingeniero Jacobacci town, Rio Negro Province, Argentina |

Types | Holotype: MLP R. 5660, adult male. Collected by J.A. Scolaro, B. Sinervo, F. Méndez de la Cruz, J. Gutiérrez and N. R. Ibargüengoytía, December 14, 2010. Paratypes: MLP-R. 5661, adult male; MLP-R. 5662, adult female; MLP-R. 5663, adult female; MLP-R. 5664, adult male; JAS-DC 1887, adult female; JAS-DC 1896, adult male; UNCo-PH 1899, adult male; UNCo-PH 1839 adult female; UNCo-PH 1894, adult female; UNCo-PH 1895, adult male; UNCo-PH 1902, adult male. The same data as detailed for the holotype. |
Diagnosis | Diagnosis: Phymaturus sinervoi is a member of the patagonicus group, distinguished from the neighbouring Phymaturus species by a peculiar colour pattern similar in both sexes (Fig. 3). The new species can be distinguished from the palluma = flagellifer group by having flat imbricate superciliaries rather than being rectangular and non-overlapping; slightly spiny and non-rugose caudal scales in verticilles (as seen among members of the palluma group). However, its subocular scale is not fragmented and it is separated from supralabials by two rows of lorilabials, as in most species of the patagonicus clade, but not seen in the majority of members of the palluma group. From the three geographically closer species, P. etheridgei, P. ceii and P. spectabilis, the new species P. sinervoi can be differentiated by its pattern of coloration (Fig. 5) as well as the morphological differences in snout-vent length, head length and width, hind or forelimb, finger and fourth toe length, axila-groin distance, finger lamellae, and in scales number, such as in supralabial, infralabial, lorilabial, scales around mental, subocular, and ventral scales (see results detailed above). P. sinervoi shows mainly a major body size and larger limbs, but minor number of ventral scales, when compared with P. ceii and P. etheridgei. The same results are obtained when compared with P. spectabilis, but showing a minor number of subocular and lorilabial rows of scales. |
Comment | |
Etymology | “The species name is dedicated to honour our friend and colleague Dr. Barry Sinervo from the Department of Ecology and Evolutionary Biology, University of California (USA), Santa Cruz; an evolutionary biologist and herpetologist who has enthusiastically and generously collaborated in many research projects in Patagonian herpetofauna for the last years.” |
