Figs. 75, 131

Polyplectropus bolivianus is readily distinguished from all other species in the P. robacki subset by the narrow and elongate dorsal branch of the inferior appendage (present also in P. robacki (Yamamoto) , P. andinensis , new species, and P. brborichorum , new species) and by the presence of endothecal phallic spines. The intermediate appendage of P. bolivianus is shorter and more robust than in P. andinensis , P. robacki , and P. brborichorum .

Adult. Length of forewing 6.5 mm, n=1. Color of head, thorax, and legs brown; setae on body grey and yellow; tegulae with long, golden brown and grey setae; setae on wings golden brown along costal margin with patches of grey setae interspersed along margin and on most of wing surface.

Male genitalia. Sternum IX in lateral view deltoid, anterior margin convex, posterior margin sinuate and submedially concave; in ventral view broadly deltoid, anterior margin concave, posterior margin highly convex. Tergum X membranous, oblong, bearing dorsal microsetae; lower lip of tergum X membranous, smooth, without dorsal microsetae, digitate; in dorsal view obtuse; in caudal view produced dorsad of phallocrypt. Intermediate appendage not longer than inferior appendage, stout, with long basal setae; in dorsal view basally broad, broadly tapering apically, directed laterad; in caudal view broad, curved, broadly narrowing and becoming sclerous apically, directed medially, with apex curved posterolaterad. Preanal appendage tripartite; dorsolateral process bulbous, originating from dorsum of mesolateral process, bearing dorsal microsetae; mesolateral process setose; in dorsal view ovate, in lateral view deltoid; mesoventral process setose; in lateral view hook-like, with basodorsal digitate lobe, with ventrad-directed sclerotized apex, ventral margin concave, posterior margin rounded; in caudal view not fused basomesally, processes separated, ventral margin of process acute, with basal, digitate, setose dorsolateral projection. Inferior appendage bipartite with anterior basal plate extending anterad beyond sternum IX when observed in lateral view; dorsal branch setose, in lateral view lanceolate, basally setose and broader, becoming highly curved, directed anterad beyond half of IX segment, recurved posteromesally; in ventral view narrow, basally sclerotized with digitate, laterally directed lobe, narrowing and recurving apically, expanding posterad into ventral branch; ventral branch setose, basally broad, in lateral view obovate, rounded posterad; in ventral view subquadrate, mesal margin straight, posterior margin rounded to truncate, shallowly converging mesally. Phallus short; dorsal phallic sclerite in lateral view cylindrical, apex pandurate; apex of dorsal phallic sclerite in dorsal view acute and sclerotized; endothecal membrane with 2 stout, medium-sized, sclerotized spines.
