Figures 53–56 , 57I , 58K Etymology. The specific epithet is a Latin noun meaning “cave”, in reference to the habitat where the specimens were found. Diagnosis. Marma spelunca sp. nov. shares most similarities with M. rosea , both with the same length of the process on the embolic disc and cymbium (proportionally to the bulb) ( Figs 57 H–I), and similar pattern of epigynal structure (copulatory ducts with similar length, encircling primary spermathecae and almost touching each other; Figs 58 J–K). However, males of M. spelunca sp. nov. can be distinguished by having a symmetrical embolic disc (both edges with the same degree of curvature; Figs 53C , 55A, C , 57I ), whereas in M. rosea , the retrolateral edge of the embolic disc has more accentuated curvature ( Figs 48C , 50A, C , 57H ). Females of M. spelunca sp. nov. also differ from those of M. rosea by having larger copulatory openings ( Figs 58 J–K). Further, the body of M. spelunca sp. nov. is larger (on average 4.50 mm in total length, while specimens of M. rosea are about 3.0 mm), being the largest species of Marma currently known.
