Cibyra ferruginosa species-group

Three species with distributions that are entirely ( C. ferruginosa ), or mostly, allopatric ( C. ochracea , C. meridionalis ) (Pl. 30, Figs 1a–b ). The distributional tracks are oriented southeast-northwest, each species having a predominantly linear distribution range (Pl. 30, Fig. 1a ). Geographic overlap between C. ochracea and C. meridionalis is limited to the southern and northern ends of their respective distributions. The northernmost locality of C. ochracea lies very close to the southern limits of C. ferruginosa . The distributional structure of this species-group is consistent with allopatric fragmentation (vicariance) of an ancestral distribution followed by marginal range expansion between C. ochracea and C. meridionalis (Plate 32, Fig. 2a–b ).
