Atelopus pachydermus (O. Schmidt) 



Figure 6 



1858. Phirix pachydermus O. Schmidt, p. 257, pi. 3, fig. 26 (type locality, "westen 

 von Neu-Granada, bei Bonaventura [= Buenaventura, Valle] in einer 

 Hohe von 5000' "). 



1926. Atelopus cruciger (not of Lichtenstein and Martins). — Nieden, 1926, p. 84. 



1963. A.[telopus] pachydermus. — Rivero, 1963c, p. 107. 



Nieden has synonymized this species with Atelopus cruciger, but 

 Venezuelan examples of cruciger have much smaller feet and hands 

 and a dorsal pattern different from that shown in Schmidt's figures. 



Figure 6. — Atelopus pachydermus (type of Phirix pachydermus; approximately 

 same size). Redrawn by Paul Laessle after O. Schmidt (1858, pi. 3, fig. 26).
