“…In this paper, we endeavored to point out and to correct species misidentifications, as Lema et al (2005) and Leynaud et al (2005). They used the name P. tricolor for specimens that correspond to P. punctatus, most likely following Lema et al (2005), who synonymyzed P. punctatus with P. tricolor, an error corrected here.…”

“…They used the name P. tricolor for specimens that correspond to P. punctatus, most likely following Lema et al (2005), who synonymyzed P. punctatus with P. tricolor, an error corrected here. This misleading synonymy was based on the examination of fixed specimens that are discolored, which are housed in Argentinean collections and labeled as "P. tricolor".…”

“…Upon studying P. tricolor specimens housed in the IBSP, Lema et al (2005) noted that the sample contained a new species, which they described as P. matogrossensis, consequently, the known distribution of P. tricolor became restricted to Paraguay. Jorge A. Abalos (Centro de Zoología Aplicada, Córdoba) had sent to Lema a drawing of a living specimen that had been determined by Lema et al (2005) as P. tricolor.…”

“…Jorge A. Abalos (Centro de Zoología Aplicada, Córdoba) had sent to Lema a drawing of a living specimen that had been determined by Lema et al (2005) as P. tricolor. Cacciali and Motte (2007) reported on the occurrence of P. matogrossensis, a species originally described to inhabit Cerrado vegetation, in Paraguay, thus restricting the distribution of P. tricolor to Chaco and Monte Desert biomes in that country.…”

“…The Phalotris tricolor group is currently represented by Phalotris cuyanus (Cei 1984), Phalotris matogrossensis Lema, D'Agostini & Cappellari 2005, Phalotris punctatus (Lema 1979), Phalotris sansebastiani Jansen & Köhler (Duméril, Bibron & Dumé-ril 1854). The mainly difference from the other groups of Phalotris Cope 1862, is the dorsal pattern uniformly colored, not striped, and immaculate ventral coloration.…”

AbstractThe species of tricolor group are redefined, because currently their limits are not very clear. Phalotris punctatus differs from P. tricolor mainly by dorsal coloration ocher reddish (vs. red), black dots widespread on dorsal side (vs. immaculate), smaller size, up to 770 mm, usually 400 mm (vs. up to 940 mm, usually 500), occurring in the biomes Monte Desert and Chaco, Argentina (vs. Austral Chaco, in Paraguay and Bolivia). Phalotris punctatus is similar to P. cuyanus differing of it mainly by presence of widespread dorsal dots (vs. absent; if present, few dots on vertebral row of scales); black head ventrally (vs. immaculate white), black snout (vs. immaculate ocher); reddish vertebral zone ocher (vs. fully ocher); and distribution in northern to western Argentina, barely reaching Paraguay (vs. northern Argentina, reaching Buenos Aires and neighboring Provinces).Keywords: Chaco, Monte, patterns, cuyanus, punctatus. ResumoAs espécies do grupo tricolor são redefinidas no presente trabalho, porque seus limites não são muito claros. Phalotris punctatus difere de P. tricolor principalmente pela coloração ocre avermelhada (vs. vermelha), pontos pretos distribuídos irregularmente na face dorsal (vs. imaculada), menor porte, até 770 mm, geralmente 400 mm (vs. acima de 940 mm, geralmente 500), ocorrendo nos biomas Deserto Monte e Chaco, Argentina (vs. Chaco Austral, Paraguai e Bolívia). Phalotris punctatus é similar a P. cuyanus diferindo desta principalmente pela presença de pontuação dorsal irregularmente distribuída (vs. ausente; ou com alguns pontos somente na linha de escamas vertebrais, se presente), cabeça preta ventralmente (vs. branca imaculada), focinho preto (vs. ocre imaculada), zona vertebral ocre avermelhada (vs. somente ocre), com distribuição ao norte e leste da Argentina e, raramente, Paraguai (vs. Argentina setentrional, incluindo Buenos Aires e províncias vizinhas).Palavras-chave: Chaco, Monte, padrões, cuyanus, punctatus.The distribution of Phalotris tricolor group in Argentina and Paraguay, with notes on its taxonomy (Serpentes, Elapomorphini)A distribuição do grupo Phalotris na Argentina e Paraguai, com notas sobre sua taxonomia (Serpentes, Elapomorphini)

A survey of the southernmost representatives of the tricolor species group, genus Phalotris (Serpentes, Colubridae). Colubrid snakes of the South American genus Phalotris are difficult to detect because of their secretive habits, and thus they are poorly represented in collections. The species Phalotris cuyanus and P. tricolor, the southernmost representatives of the tricolor species group, were studied to determine the limits of intraspecific variation of P. cuyanus and to consolidate the taxonomic relationship between both species, the phenetically and geographically closest members in the group. The distribution of selected external characters (cephalic, ventral and subcaudal scales), coloration pattern, width of white and black collars, and hemipenis morphology were analyzed. Comparative data on the other members of the group, P. mertensi and P. matogrossensis, are briefly discussed. Males of P. cuyanus have a higher number of ventral scales than males of P. tricolor (mean of 220.3 vs. 204.6). Cephalic melanism varies among individuals and does not have discriminant or geographic value for this species group. The white nuchal collar may partially cover the parietal scales in the four species. The black collar is moderately narrow in P. cuyanus, but it can be up to 12 scales wide in P. tricolor. Vertebral dotting is neither constant nor exclusive of any species. The four species of the group are well characterized by combinations of character states for each one. We suggest considering to P. cuyanus as an evolutionary species typical of the Monte biogeographic province.

Three valid species of Haplometroides Odhner, 1910 parasitise snakes and amphisbaenians from South America. This study provides additional data on morphometric and molecular phylogenetic position inferred from the nuclear ribosomal gene 28S (partial). DNA sequences were isolated from Haplometroides intercaecalis Silva, Ferreira and Strüssmann, 2007 found in one specimen of Phalotris matogrossensis Lema, D'Agostini and Cappellari, 2005. Five digenean specimens were recovered from the esophagus of this snake, and four specimens were used for morphometrical studies and one specimen for molecular analysis. Phylogenetic analysis using maximum likelihood and Bayesian methods was conducted with sequences available for the order Plagiorchiida and its phylogenetic position places H. intercaecalis among the brachycoeliids Brachycoelium (Dujardin, 1845) Stiles and Hassall, 1898 and Parabrachycoelium Pérez-Ponce de León, Mendoza-Garfias, Razo-Mendivil and Parra-Olea, 2011, and the mesocoeliid Mesocoelium Odhner, 1910, not closely related to plagiorchids as expected. Due to morphological differences among these families, it may be necessary to create a new family to accommodate Haplometroides spp. However, more genera/taxa as well as other molecular markers should be added in future studies to confirm our results and resolve this matter. This is the first phylogenetic positioning of digeneans of the genus Haplometroides, contributing to the systematic analysis of the helminthological biodiversity of Neotropical snakes.
