Differential diagnosis

The new species resembles D. longa sp. nov. (Figs 2–3) in having a long tibia (longer than half the length of the cymbium), short septum (located in fovea), but differs by having the tibia shorter than the length of the cymbium (vs as long as cymbium), stronger and longer mesal process (as long as retrolateral process) (Figs 6A–C, 7C–E) (vs shorter than the length of the posterior arm, Figs 2A–C, 3C–E), and the copulatory openings located ectally from spermathecae (Figs 6D, 7F) (vs located mesally, Figs 2D, 3F).

Etymology

The specific epithet comes from the Latin adjective ‘ pullus ’, meaning ‘black’ and refers to the body color of the male.

PALP (Figs 6A–C, 7C–E). Tibia short, about 2 times as long as wide, almost half of cymbium length. Retrolateral tibial apophysis (RTA) laminar and tip almost pointed ventrally in dorsal view. Cymbium 2 times as long as wide. Basidorsal fold (BF) forms right angle, finger-like in retrolateral view. Posterior arm of conductor with 2 large processes: mesal process (MPA) hook-like, tip slightly twisted; retrolateral process (RPA) wide and laminar, as long as mesal process. Embolus originating at about 11:30 o’clock position, distal part hidden by conductor.
