Polyplectropus manuensis , new species

Figs. 64, 139

This is a typical species of the P. manuensis group differing from P. robertsonae , new species and P. tripunctatum , new species by the bifid apex of the mesoventral process of the preanal appendage (trifid in P. tripunctatum and P. robertsonae , yet middle lobe attenuate in the latter species) and by the shape of the ventral branch of the preanal appendage, produced as a small lobe when viewed in lateral view, not bifid as in P. tripunctatum or downturned and basally rounded as in P. robertsonae .

Adult. Length of forewing 4.8–5.5 mm, n = 2. Color of head, and thorax brown, 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 ventrally produced, posterior margin submedially produced; in ventral view rectangular, anterior margin sinuate and medially highly concave, posterior margin sinuate. Tergum X membranous, oblong, bearing dorsal microsetae; lower lip of tergum X membranous, smooth, without dorsal microsetae, digitate and elongate; in dorsal view digitate; in caudal view produced dorsad of phallocrypt. Intermediate appendage not longer than inferior appendage, small, digitate, with long setae throughout; in dorsal view deltoid; in caudal view rounded, small, arising at base of mesolateral process of preanal appendage, directed posterolaterad. Preanal appendage tripartite; dorsolateral process elongate, originating from dorsum of mesolateral process, directed anterad, recurved posteromesad then posterolaterad, tapering into acute apex; mesolateral process setose; in dorsal view obovate, in lateral view broadly convex; mesoventral process setose, in lateral view digitate, tapering ventrally into sclerotized apex, ventral margin concave, posterior margin slightly angled; in caudal view fused basomesally, ventral margin of process acute, 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 narrowly oblong, directed dorsad; in ventral view narrow, broadening apically, lateral margin subapically produced, sinuate, posterior margin emarginate, mesal margin sinuate, shallowly fused to ventral branch; ventral branch setose, short, in lateral view digitate, narrowing posterad; in ventral view subquadrate, mesal margin straight, posterior margin truncate, gradually converging mesally. Phallus short; dorsal phallic sclerite in lateral view sinuate, apex oblong; apex of dorsal phallic sclerite in dorsal view rounded.
