description
Description: Male holotype. Length, about 11 mm, width 1.0 mm. Five ommatidia in two rows. Labrum with long, slightly sinuous hooks at each angle. Mandibles not modified. Legpairs 1 and 2 similar in size (Fig. 35); legpair 1 without needle-like long setae, tarsi with spatulate, twisted setae ventrally. Second trochanters with moderate posteriorventral processes, bearing groups of specialized setae. Legs 3 with coxal flasks long, asetose, diverging; prefemora distally expanded, telopodites not strikingly reduced (Fig. 35). Pleurotergal bars of ring 3 expanded, angular distally, overlapping in midline. Crests moderate. Pygidium short. Color uniform medium brown. Gonopod (Figs. 37, 54, 55) anterior angiocoxites with broad, two-toothed lateral process, smaller teeth distally on posterior surface. Posterior angiocoxites narrow at origin, broadening distally, sheathing 3 or possibly 4 long flagellocoxites. Ninth legpair with small distal coxal process, flattened telopodites articulating loosely with depression on pleural margin of ring 7 (Fig. 36). Females not collected.
