FIGURE 6 in A new species of Anomaloglossus (Anura: Aromobatidae) from the Pakaraima Mountains of Guyana
FIGURE 6. Graph showing correlation between HL3 and BEL with standard errors for adult female specimens of Anomaloglossus tepuyensis (green triangles) and A. megacephalus sp. nov. (orange circles). Abbreviations are defined in the text. The graph clearly shows that the head of A. megacephalus sp. nov. is proportionally longer that the head of A. tepuyensis.
FIGURE 5 in A new species of Anomaloglossus (Anura: Aromobatidae) from the Pakaraima Mountains of Guyana
FIGURE 5. Comparison of Anomaloglossus megacephalus sp. nov. and the similar A. tepuyensis and A. parkerae. A: Dorsal view of preserved specimens of (from left to right) A. megacephalus sp. nov. (IRSNB 1986, 27.3 mm SVL), A. tepuyensis (MHNLS 17401, 23.3 mm SVL) and A. parkerae (MHNLS 11089, 23.2 mm SVL). B: Comparison between midline distance from snout tip to an imaginary line between anterior arm insertions and the same distance reported posteriorly from the same imaginary line in A. megacephalus sp. nov. and A. tepuyensis. In most A. megacephalus specimens (left, IRSNB 1986, 27.3 mm SVL) the distance reaches or surpasses the anterior insertion of thigh, whereas in all specimens of A. tepuyensis examined (right, MHNLS 17401, 23.3 mm SVL), the distance fails to reach the thigh. Photos by PJRK.
