O osteocrânio de Proceratophrys boiei (Wied-Neuwied), P. appendiculata (Günther), P. melanopogon (Miranda-Ribeiro) e P. laticeps Izecksohn & Peixoto (Anura, Leptodactylidae)

Abstract

Foram comparados alguns ossos do crânio de quatro espécies de Proceratophrys Miranda-Ribeiro, 1920 que compartilham longos apêndices palpebrais, como sejam: P. boiei (Wied-Neuwied, 1825), P. appendiculata (Günther, 1873), P. melanopogon (Miranda-Ribeiro, 1926) e P. laticeps Izecksohn & Peixoto, 1981. Com base na forma dos frontoparietais, (com cristas laterais elevadas), na posição dos cantos dos quadratojugais em relação ao plano vertical dos côndilos occipitais, na ornamentação das superfícies cranianas (com tubérculos e grânulos), e na presença de fossetas maxilares posteriores ventrais, P. boiei, P. appendiculata e P. melanopogon foram consideradas em um mesmo grupo. P. laticeps, entretanto, por apresentar arcadas temporais completas (semelhante a Ceratophrys Wied-Neuwied, 1824), cantos dos quadratojugais posteriores ao plano vertical dos côndilos occipitais, superfícies cranianas rugosas e ausência de fossetas maxilares posteriores ventrais, é considerada pertencente a um grupo separado.

The tadpole of Proceratophrys izecksohni (Amphibia: Anura: Odontophrynidae)

“…The species of Proceratophrys have been clustered in species groups or complexes based on overall morphological similarity (LYNCH 1971, IZECKSOHN et al 1998, GIARETTA et al 2000, KWET & FAIVOVICH 2001, PRADO & POMBAL 2008.Species without palpebral appendages are assigned to the Proceratophrys bigibbosa and P. cristiceps species groups. Species of the Proceratophrys cristiceps group occur in open and dry environments of Cerrado and Caatinga.…”

“…Currently four species are assigned to the group: P. avelinoi Mercadal de Barrio & Barrio, 1993; P. bigibbosa (Peters, 1872); P. brauni Kwet & Faivovich, 2001; and P. palustris Giaretta & Sazima, 1993. Species with a long and single palpebral appendage are placed in the Proceratophrys appendiculata and P. boiei groups (IZECKSOHN et al 1998, PRADO & POMBAL 2008, CRUZ & NAPOLI 2010, DIAS et al 2013a. The species of the P. boiei group occur primarily in the Atlantic Forest, from Paraíba to Santa Catarina states (PRADO & POMBAL 2008): P. boiei (Wied-Neuwied, 1824); P. paviotii Cruz, Prado & Izecksohn, 2005; and P. renalis (Miranda-Ribeiro, 1920).…”

The ten included species, listed below, are characterized by the presence of a triangular rostral appendage: P. appendiculata (Günther, 1873); P. belzebul Dias, Amaro, Carvalho-e-Silva & Rodrigues, 2013; P. izecksohni Dias, Amaro, Carvalho-e-Silva & Rodrigues, 2013; P. laticeps Izecksohn & Peixoto, 1981; P. melanopogon (Miranda-Ribeiro, 1926); P. moehringi Weygoldt & Peixoto, 1985; P. phyllostomus Izecksohn, Cruz & Peixoto, 1998; P. sanctaritae Cruz & Napoli, 2010; P. subguttata Izecksohn, Cruz & Peixoto, 1998; and, P. tupinamba Prado & Pombal, 2008.…”
