Figure 1. Phylogenetic relationships among genera and species groups within Centrolenidae. A in Glass frogs (Centrolenidae) of Yanayacu Biological Station, Ecuador, with the description of a new species and comments on centrolenid systematics

Figure 1. Phylogenetic relationships among genera and species groups within Centrolenidae. A, tree topology suggested by Ruiz-Carranza & Lynch (1991a, b, c, 1996, 1998) and modified by Bolívar et al. (1999), Señaris (2001) and Duellman & Señaris (2003). B, single, most-parsimonious tree of the phylogenetic relationships of Centrolenidae (tree length = 13, CI = 0.923, RI = 0.9474, RC = 0.8745). Numbers refer to the following characters: (1) tibiale and fibulare, 0 = not fused, 1 = partially or completely fused; *(2) T-shaped terminal phalanges, 0 = absent, 1 = present; (3) dilated medial process on Metacarpal III, 0 = absent, 1 = present; (4) eggs deposition site, 0 = deposited in water, 1 = not deposited in water, 2 = deposited on underside of leaves; (5) shape of liver, 0 = liver lobed, 1 = liver bulbous; (6) humeral spine in males, 0 = absent, 1 = present; (7) relative size of disc of Finger III, 0 = disc small (<80% of eye diameter), 1 = disc large (> 80% of eye diameter); (8) coloration of hepatic peritoneum, 0 = clear, 1 = white; (9) coloration of peritoneum covering urinary blad- der, 0 = clear, 1 = white; (10) red heart visible in ventral view, 0 = heart not visible, 1 = red heart visible; (11) coloration of parietal peritoneum, 0 = white, 1 = clear. Character 12 (venter-to-venter fight behaviour) was hypothesized to be a synapomorphy shared by Centrolene and Cochranella (Bolívar et al., 1999); however, the distribution of this behaviour has been reported in only nine species (Guayasamin & Barrio-Amorós, 2005) and we did not include in B. Numbers next to tick marks represent bootstrap support values. Grey boxes denote characters that appear more than once in the tree. *T-shaped terminal phalanges are also present in Allophryne ruthveni.
