Polyplectropus carolae Bueno-Soria, 1990: 364 . [Type locality: Mexico, Veracruz, Estación de Biología —UNAM "Los Tuxtlas" unnamed stream E. of station, NMNH, male.]

Polyplectropus carolae resembles P. thilus (Denning) in the presence of an elongate, dorsolateral process and shape of the mesoventral process of the preanal appendage, in the shape of the dorsal branch of the inferior appendage, and in the overall shape of the phallus. Polyplectropus carolae can be distinguished from P. thilus by the elongate ventral branch of the inferior appendage, being almost 2 / 3 as long as the dorsal branch and ½ as long as in P. thilus , by the broader intermediate appendage, by the more robust papillate lobe, and by the shorter, yet still elongate, dorsolateral process of the preanal appendage.

Adult. Length of forewing 3.8 mm, n = 2. Color of head, thorax, and legs yellowish-brown (specimens preserved in alcohol).

Male genitalia. Sternum IX in lateral view deltoid, anterior margin entire, posterior margin sinuate and submedially 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, smooth, without dorsal microsetae; in dorsal view digitate; in caudal view produced dorsad of phallocrypt. Intermediate appendage not longer than inferior appendage, broad and membranous and with long apical setae and ventral digitate lobe; in dorsal view digitate; in caudal view broadly deltoid, produced posteroventrad, directed posterolaterad, ventral projection may be papillate lobe. Preanal appendage tripartite; dorsolateral process elongate, directed anterad, recurved posteromesad then posterolaterad, tapering mesally into acute apex; mesolateral process setose; in dorsal view obovate, in lateral view orbicular; mesoventral process setose; in lateral view hook-like, with ventrad-directed sclerotized apex, ventral margin concave, posterior margin convex; in caudal view processes separated, ventral margin of process acute, with ventrolateral margin slightly produced. Inferior appendage bipartite with anterior basal plate not extending anterad beyond sternum IX when observed in lateral view; dorsal branch setose, in lateral view pandurate, posterior margin truncate; in ventral view narrow, lateral margin slightly convex, slightly undulate, posterior margin rounded, mesal margin entire, expanding posterad into ventral branch; ventral branch setose, elongate, bearing 4–7 robust, sclerotized spines along entire dorsal surface; in lateral view lanceolate, narrowing posterad; in ventral view deltoid, posteromesal margin convex, gradually converging mesally. Phallus long; dorsal phallic sclerite in lateral view sinuate, apex oblong; apex of dorsal phallic sclerite in dorsal view emarginate; endothecal membrane without embedded spines.

Remarks. The abdomen of the holotype was not found in the vial. However, paratype were compared with the original description and illustrated.
