FIGURE 4. Scatterplot of relative femoral gland length (FGL/SVL ratio) and relative distance between inner edges of femoral glands (FGD/SVL) in the three endemic Blommersia species of Madagascar's northern central east coast, and B. wittei. Based on measurements provided in Table 1 (B. variabilis sp. nov. and some B. wittei) and Vences et al. (2010) for B. dejongi and B. galani, as well as type specimens of B. wittei (only male specimens with complete measurement data were used). Arrow points to a putative hybrid between a female B. galani and male B. dejongi (specimen ZSM 452/2006).
