Polyplectropus adamsae , new species

Figs. 48F–H, 133

This species is most similar to P. mignonae Bueno-Soria in the shape of the phallus and the intermediate and preanal appendages. While similar overall, the dorsal branches of the inferior appendages of the 2 species differ. Polyplectropus adamsae has a narrower dorsal branch with apical and preapical spines, whereas P. mignonae has a basally broader dorsal branch and the spines are located apically.

Adult. Length of forewing 4.2–5 mm, n = 41. Color of head, thorax, and legs yellowish-brown; setae on body grey and golden brown; tegulae with long, golden brown and grey setae; setae on wings darker brown along costal margin, rest of wing lighter shade of brown with scattered patches of grey setae.

Male genitalia. Sternum IX in lateral view broadly deltoid, anterior margin convex, posterior margin sinuate and medially produced; in ventral view rectangular, anterior margin concave, posterior margin with median flange. Tergum X membranous, oblong, bearing dorsal microsetae; lower lip of tergum X membranous bearing microsetae, digitate and slightly ridged; in dorsal view digitate; in caudal view produced dorsad of phallocrypt. Intermediate appendage as long as inferior appendage, narrowly digitate with long setae throughout; in dorsal view digitate, linear; in caudal view digitate, elongate, apically curved, directed posterolaterad. Preanal appendage bipartite; mesolateral process setose; in dorsal view oblong, in lateral view oblong; mesoventral process setose; in lateral view quadrate with ventrad-directed sclerotized apex, anteroventral margin concave, posterior margin truncate; in caudal view processes separated, ventral margin of process rounded. Inferior appendage bipartite with anterior basal plate not extending anterad beyond sternum IX when observed in lateral view; dorsal branch setose, in lateral view obclavate, curved and narrowing apically, with subapical and apical spines; in ventral view narrow, lateral margin convex, entire, posterior margin subacute, mesal margin entire, concave, expanding posterad into ventral branch; ventral branch setose, short, bearing a row of 4–7 robust, sclerotized spines along posterior margin; in lateral view clavate, rounded posterad; in ventral view subquadrate, posteromesal margin convex, mesal margin slightly concave, gradually converging mesally. Phallus short; dorsal phallic sclerite in lateral view cylindrical, apex pandurate to oblong; endothecal membrane without embedded spines.

Female genitalia. Very similar to the female of P. bredini .
