Fig. 2 in Nuptial pads of rock frogs (Thoropa, Cycloramphidae, Anura): How papillary epidermal projections are related to sexual maturity and taxonomy

Fig. 2. Ventral and dorsal views of the hand of Thoropa indicating the regions of the hand where papillary epidermal projections (PEPs) occur: "MPA-II" = metacarpal-phalangeal articulation of finger II; "IMT" = inner metacarpal tubercle; "P-II" = basal phalange of finger II; "M-II" = metacarpus of finger II; finger II itself; finger III; finger IV; and finger V. Finger numbers follow Fabrezi and Alberch (1996). Modified from Rebouças et al. (2017).
