Male median lobe ( Figs 12 View FIGURES 11–13 d–f) in lateral view slender, width nearly uniform along its length, narrowed at apex, strongly curved dorsally at about mid length, ventrally with deep longitudinal groove subtended by lateral flanges, left lateral flange slightly enlarged, expanded ventrally, converging with right side at or near apex to create rounded lobe, base small, comprised of lateral notches and a medial hook-like process; left lateral lobe in lateral view ( Fig. 12b View FIGURES 11–13 ) elongate, slender, slightly curved, with hair-like setae on distal third, longer at apex forming a dense tuft.
