Fig. 1 in Nuptial pads of rock frogs (Thoropa, Cycloramphidae, Anura): How papillary epidermal projections are related to sexual maturity and taxonomy

Fig. 1. Photos of the three basic types and distribution of papillary epidermal projections (PEPs) of Thoropa. (A, B) Dorsal and ventral views of the hand of a specimen of Thoropa lutzi from Rio de Janeiro, Rio de Janeiro state, Brazil (MZUSP 88241) showing cone-shaped PEPs (not the focus of the present study). (C, D) Dorsal and ventral views of the hand of a specimen of Thoropa petropolitana from Guapimirim, Rio de Janeiro state, Brazil (EI 9474) showing spineshaped PEPs located only on the metacarpalphalangeal articulation of finger II (MPA-II). (E, F) Dorsal and ventral views of the hand of a specimen of Thoropa taophora from S˜ao Sebasti˜ao, S˜ao Paulo state, Brazil (EI 9474) showing spine-shaped PEPs on the metacarpal-phalangeal articulation of finger II (MPAII), inner metacarpal tubercle (IMT), other regions of finger II, finger III, and finger IV.
