Amphibia, Anura, Cycloramphidae, Proceratophrys avelinoi Mercadal de Barrio and Barrio, 1993: distribution extension and distribution map (original) (raw)

Notes o N GeoGraphic DistributioN 332 Proceratophrys avelinoi is one of the four species included in the P. biggibosa species group, revised by Kwet and Faivovich (2001). The members of this group are characterized by the presence of postocular swellings and the absence of palpebral appendages, accompanied by cryptic, dorsal brownish coloration with red, orange, or tan colored ventral surface which is black spotted (Kwet and Baldo 2003), note many collection specimens loose their ventral coloration. P. avelinoi is a small sized member of this group (Table 1). This species can be identified by its small postocular swelling, light brown coloration on the suprascapular region, and orange reddish blotches on the venter (Figure 1). It is distinguished from P. bigibbosa by the much smaller size, fainter postocular swelling; from P. brauni by the smaller size, rounded snout, and lessdeveloped palpebral tubercles; from P. palustris because P. avelinoi has lighter coloration on the suprascapular region, better defined dorsal row of tubercles, and significantly smaller size in males (Kwet and Faivovich 2001).
