Ventral part with fine, inconspicuous punctation, invisible on metaventrite and metacoxae and weak on abdominal ventrites; prosternum smooth medially; metaventrite and metacoxae with weak microreticulation; on abdominal ventrites microreticulation almost invisible; metacoxal plates with numerous, strongly impressed longitudinal strioles, abdominal ventrites 1 and 2 with numerous, long, longitudinal strioles from margin to margin, on abdominal ventrites 3 and 4 strioles situated laterally and turn to middle, almost horizontal, abdominal ventrites 5 and 6 without strioles but with fine punctation that sparser medially and forms a dense, rugose lateral area at each side.

: Protibia almost straight, not modified. Proclaws rather long, subequal in length; anterior more strongly curved than posterior one. Median lobe of aedeagus with two lobes of dorsal sclerite rather narrow; left dorsal lobe distinctly shorter that right one, with small apical crest; apex of left dorsal lobe curved downwards and to left, its very tip upwards; dorsally and laterally with denticulation (spinulae) visible in lateral left view; right dorsal lobe with distinct, but shallow, elongate median impression and an weak angular convexity above it; apex of right dorsal lobe large, swollen, rounded; left lobe of ventral sclerite with its sclerotised area long, thin, narrowly pointed apically, shorter than right ventral and dorsal lobes and 4/5 of length of left dorsal lobe. Paramere with setae not clearly divided into distal and proximal; more distally situated setae longer and slightly denser than more proximal ones; with several, short, thin the most proximal setae standing separately (Fig.
