FIGURE 1. Area map of Mount Maringma showing the type locality of Pantepuisaurus rodriguesi gen. nov. sp. nov. (red dot). Coordinates and boundary with Brazil are approximate and based on the available map (note that there is a substantial difference in the country boundary between this map and that shown in Google Earth). Maps elaborated after "Roraima Sheet 40 SE" published by the Survey Department of Guyana, 1972, and a radar image of South America by NASA/JPL/NIMA available at http://photojournal.jpl.nasa.gov/catalog/PIA03388.

FIGURE 4 in A new species of Rhinatrema Duméril & Bibron (Amphibia: Gymnophiona: Rhinatrematidae) from Guyana

FIGURE 4. Volume reconstruction of HRXCT data showing Rhinatrema shiv sp. nov. (holotype IRSNB 1991: left column) and R. bivittatum (MW2051: right column). From top to bottom: crania in dorsal, palatal, lateral view and mandibles in lateral and dorsal view. Arrows in palatal views point to postchoanal processes of right maxillopalatines. See Nussbaum (1977) for figures and description of the cranial and mandibular osteology of rhinatrematids. Scale bar = 1mm.

FIGURE 3. Anomaloglossus megacephalus sp. nov., showing intra- and interpopulational variation in dorsal (A) and ventral (B) pattern in preservative. Two upper specimens are from Mt. Ayanganna: ROM 39637 (upper left, female 28.3 mm SVL) and ROM 39638 (upper right, female 27.9 mm SVL). Lower specimen is the holotype (female 27.3 mm) from Maringma Tepui. Photos by PJRK.

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.
