Xeromiturga bidgemia sp. nov.

Fig. 75 View FIGURE 75

Diagnosis. Males differ from those of Xer. mardathuna sp. nov. in the absence of an apical barb on the dorsal lobe of RTA ( Fig. 75e View FIGURE 75 ), and the base of the embolus without a retrolateral bulge ( Fig. 75a View FIGURE 75 ). Female unknown.

Etymology. The species epithet is a noun in apposition from the type locality.
