[ Typelocality: Panama, Cerro Punta; INHS; male; in  Polycentropus].—  Flint, 1968: 21[to  Polyplectropus].   Polyplectropus deltoidesis most similar to  P. cuzcoensis, new speciesbased on the overall shape of the inferior appendage, on the presence of a dorsolateral process of the preanal appendage, and on the overall shape of the intermediate appendage.  Polyplectropus deltoidescan be distinguished from  P. cuzcoensisby the hook-like shape of the mesoventral process of the preanal appendage, being cylindrical in  P. cuzcoensis, by the longer and sinuate dorsolateral process of the preanal appendage, which lacks modifications on the apex, by the shorter, more rounded ventral branch and broader dorsal branch of the inferior appendage, and by the elongate intermediate appendage.   Adult.Length of forewing 4.2–8 mm, n = 30. 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 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 entire, posterior margin sinuate; in ventral view rectangular, anterior margin sinuate, posterior margin with slight median flange. Tergum X membranous, oblong, bearing dorsal microsetae. Intermediate appendage as long as inferior appendage, digitate, with long and short setae throughout; in dorsal view oblong; in caudal view digitate, narrowing apically, directed posteromesad; median papillate lobe small, flanking phallocrypt laterally, bearing small apical setae. Preanal appendage tripartite; dorsolateral process elongate, originating from dorsum of mesolateral process, directed anterad, recurved posteromesad then posterolaterad, tapering mesally into acute apex; mesolateral process setose; in dorsal view oblong, in lateral view orbicular; mesoventral process setose; in lateral view hook-like, tapering ventrally into sclerotized apex, anteroventral margin concave, posterior margin convex; in caudal view processes slightly separated, ventral margin of process subacute, with ventrolateral margin entire. 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 variable, from truncate to rounded; in ventral view narrow, lateral margin slightly convex, entire, posterior margin subacute, mesal margin slightly undulate, slightly convex, becoming concave, expanding posterad into ventral branch; ventral branch setose, short, bearing 4–7 robust, sclerotized spines basally and apically; in lateral view clavate, rounded posterad; in ventral view subquadrate, mesal margin straight, gradually converging mesally. Phallus short; dorsal phallic sclerite in lateral view sinuate, apex tapering ventrally; apex of dorsal phallic sclerite in dorsal view truncate; dorsolateral arm of dorsal phallic sclerite in lateral view tapering subapically; in dorsal view tapering subapically; endothecal membrane without embedded spines.   FIGURE 104.Male genitalia of  Polyplectropus deltoides( Yamamoto, 1967)(holotype): A—left lateral view and inset of mesoventral process of preanal appendage and papillate lobe of intermediate appendage; B—dorsal view; C—caudal view; D—ventral view; E–F—phallus: E—left lateral view; F—apex (drawn free hand), dorsal view; G—mesoventral process of left preanal appendage (drawn free hand), ventral view.  Female genitalia.
