Polyplectropus mathisi Bueno-Soria, 1990: 377 . [Type locality: Panama, Chiriquí, Fortuna Dam Site nr. Hornitos ; NMNH; male.]

Polyplectropus mathisi is most similar to P. mignonae Bueno-Soria in the shapes of the intermediate appendage, the mesoventral process of the preanal appendage, and the phallus. However, P. mathisi is quite distinct due to the elongate, narrow and sinuate dorsal branch of the inferior appendage, the digitate mesolateral process of the preanal appendage, and the absence of an apical row of peg-like setae on the ventral branch of the inferior appendage.

Adult. Length of forewing 5.2 mm, n = 1. Color of head, thorax, and legs yellow (specimen preserved in alcohol).

Male genitalia. Sternum IX in lateral view deltoid, anterior margin submedially produced, posterior margin supramedially convex; in ventral view rectangular, anterior margin concave, posterior margin convex. Tergum X membranous, oblong, bearing dorsal microsetae; lower lip of tergum X membranous, smooth, without dorsal microsetae; 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, directed posterad. Preanal appendage bipartite; mesolateral process setose; in dorsal view digitate, in lateral view digitate; mesoventral process setose; in lateral view quadrate with ventrad-directed sclerotized apex, anteroventral margin straight, posterior margin truncate; in caudal view processes separated, ventral margin of process subacute, basally broad. Inferior appendage bipartite with anterior basal plate not extending anterad beyond sternum IX when observed in lateral view; dorsal branch setose, in lateral view elongate and narrow, medially curved dorsad, bearing setae on rounded apex; in ventral view narrow, lateral margin convex, entire, mesal margin entire, concave, expanding posterad into ventral branch; ventral branch setose, short, in lateral view clavate, apically produced dorsad; in ventral view subquadrate, posteromesal margin angled, mesal margin straight, gradually converging mesally. Phallus long; dorsal phallic sclerite in lateral view cylindrical, apex pandurate to oblong; endothecal membrane without embedded spines.
