Metatibia with dorsal edge very weakly denticulate, subapically with constriction; ventrally with sparse row of long setae. Meso- and metathorax ventrally densely squamose with erect plumose scales. Abdominal ventrites 1–2 concave, subglabrous, almost impunctate, sublaterally with sparse suberect scales; ventrite 5 flat, densely punctate, punctures with dense erect scales, interspaces microreticulate. Penis (Fig. 22b) with sides of body subparallel, near middle with very shallow constriction; apex with median extension, with sparse setae; apodemes 2.0× as long as body of penis; transfer apparatus long spiniform, pointing basad, with complex supporting sclerites; basal sclerite elongate V-shaped; ductus ejaculatorius with bulbus.
