Diagnosis. This species belongs to the Neotrichia caxima Species Group of Marshal (1979). The male of Neotrichia damurida sp. nov. is similar to that of Neotrichia rotundata Flint 1974, resembling this species mainly by the highly reduced inferior appendages and the general aspect of tergum X. However, in the new species the subgenital plate is triangular in ventral view (rectangular in N. rotundata) and the phallus has a slender and membranous apex while in N. rotundata the phallus ends in a small twisted spine and a slender apical tube.
F IGURE 6. Neotrichia spp. nov., male genitalia. 6, Neotrichia damurida sp. nov.: 6A, left lateral; 6B, ventral; 6C, dorsal; 6D, left inferior appendage, left lateral (enlarged). 6E, phallus, dorsal.
Description. Male (in alcohol): Dark brown species with length of each forewing 1.8 mm (holotype). Postoccipital setal warts pronounced, large, ovoid. Antennae each with 18 articles; scape normal, cylindrical, slightly longer than pedicel; flagellomeres of pedicel size, long, cylindrical. Maxillary palp formula I-II-IV-III-V (shortest to longest), first two articles extremely short, shorter than wide. Mesoscutellum anterior margin convex; metascutellum convexly subtriangular. Sternum VII with apicomesal process.
Male genitalia. Segment IX arising from within segment VIII, anterior margins concave in dorsal view; in ventral V-shaped and with basomesal process; posterior margins quadrate in dorsal view, with two pairs of apicolateral setae dorsally; in lateral view with anterior margins produced anterad mesally, ventral margin slightly concave. Segment X membranous, fused with dorsum of segment IX; with large rounded apex in lateral view; in dorsal and ventral views subquadrate with emarginated posteromesal margin. Subgenital plate developed as narrow triangular plate in ventral view, bearing two long apical setae. Inferior appendages highly reduced in lateral view; in ventral view short, apically blunt, triangular in shape, each with inner mesal margin produced and sclerosed; small digitate lobe at base. Phallus slender distally; paramere around shaft and extending posteriorly; long process arising immediately beyond base of paramere and tapering toward apex; ejaculatory duct protruding apically.
Female, larva, pupa, and egg. Unknown.
