Lynch's Toad

description

Rhaebo glaberrimus and R. nasicus, like R. lynchi, have ulnar and tarsal tubercles, but these are very low and round in R. glaberrimus and R. nasicus (very prominent and subacuminate in R. lynchi); R. glaberrimus also has a short inner tarsal fold (absent in R. lynchi), R. glaberrimus lacks metacarpal and metatarsal folds (present in R. lynchi) and the cloacal opening is at lower level of thighs or ventral in R. glaberrimus (at upper level of thighs in R. lynchi). R. lynchi, like R. nasicus, has prominent metatarsal and metacarpal folds (Plates 1 – 3; Hoogmoed 1977), but R. nasicus differs also from R. lynchi in having a prominent inner tarsal fold and the head with low but prominent bony ridges (absent in R. lynchi). R. blombergi has low and round ulnar tubercles (very prominent and subacuminate in R. lynchi), R. blombergi lacks outer tarsal tubercles (very prominent and subacuminate in R. lynchi), R. blombergi has long limbs (short limbs in R. lynchi), R. blombergi lacks metacarpal and metatarsal folds (present in R. lynchi) and R. blombergi has an inner tarsal fold (absent in R. lynchi). R. caeruleostictus has tarsal tubercles, although these are not very prominent as in R. lync

diagnosis

Diagnosis. A species of Rhaebo characterized by having a row of very prominent, subacuminate tarsal tubercles on the outer edge (Figure 1 A, 3 A – B) and very prominent, subacuminate ulnar tubercles (Figure 3 C). Comparison with other species. Rhaebo lynchi also differs from any other known Rhaebo by having a smaller size (37.5 mm SVL in the adult female) versus 190.5 – 234.5 mm. SVL in adult females of R. blombergi; 71.6 – 92.3 mm. SVL in adult females of R. caerulestictus (Hoogmoed 1989); 58.8 – 69.0 mm. SVL in adult females of R. glaberrimus; 121.3 – 146.9 mm. SVL in adult males of R. guttatus; 77.7 – 111.3 mm. SVL in adult females of R. haematiticus [although Savage (2002) reported adult females between 50 – 80 mm]; 64.4 and 66.5 mm. SVL in adult females of R. nasicus (Hoogmoed 1977).
