Miturgopelma bogantungan sp. nov.

Fig. 15

Diagnosis. Males resemble those of Miturgopelma echidna sp. nov., but the median apophysis is very distal and there are no “tiger” marks on the dark, mottled opisthosoma, and differs from those of M. australiensis by the shorter dorsal lobe of the RTA. Female epigyne with roughly V-shaped ridges.

Etymology. The species epithet is a noun in apposition from one of the localities where the species has been recorded.
