Type species

Orangutana setosa Golovatch, 1996 , by original designation.

Amended diagnosis

Body small to medium-sized (ca 11–35 mm long, ca 0.9–5.1 mm wide), with 20 rings. Paraterga from moderately to strongly developed. Transverse metatergal sulci distinct. Legs relatively long and slender, without modifications. Adenostyles absent. Sternal lamina present only between male coxae 4. Postcollum metaterga each with a dense row of uniform setae at posterior margin.

Gonopods simple to relatively complex; coxa long and subcylindrical, sparsely setose distoventrally, without tubercles; prefemoral part of telopodite densely setose, relatively short, 1/4–1/5 as long as acropodite; femoral part very long and slender, without evidence of torsion (= seminal groove running only mesally); solenophore hypertrophied due to both a well-developed lamina lateralis and a distally strongly notched lamina medialis, both laminae sheathing most of a relatively short and flagelliform solenomere; free solenomere branching off proximally, not extended to the same height as the sulcus demarcating the solenophore.
