Cibyra munona species-group

Five species with a wide disjunction between two reciprocally allopatric species in the south ( C. munona, C. yumiko sp. nov.), and three species in the north, where one is localized and disjunct ( C. serra sp. nov.), overlapping the tracks of C. agnes sp. nov. and C. alina sp. nov. (Plate 32, Fig. 4a). This pattern is consistent with ancestral allopatry followed by range expansion between C. agnes sp. nov. and C. alina sp. nov. The disjunction between the southern and northern parts of the species-group range may be the result of marine incursion over former habitat now submerged (Plate 32, Fig. 4b).
