Park, Kyu-Tek & Prins, Willy De, 2019, Re-examination of the type specimens of Lecithoceridae (Lepidoptera), deposited in the Royal Museum for Central Africa (RMCA), Belgium, with descriptions of ten new species from DR Congo belonging to Thubdora Park and Torodora Meyrick, Zootaxa 4571 (4), pp. 451-476 : 460-461

Thubdora neobarbata Park & De Prins , sp. nov.

( Figs. 7 A–E)

Types. Holotype: male, Coll. Mus. Congo, [ Equateur], Flandria , 10.ix. [19]35, J. Ghesquière, gen. slide no. CIS- 7157/ Park, in RMCA . Paratype: 1♂, Coll. Mus. Tervuren, Kinshasa (Lovanium) 14.xii.1966, Dr. J. P. Bastin, gen. slide no. CIS-7244/ Park, in RMCA .

Diagnosis. The new species is superficially similar to the following new species, T. seydeli sp. nov., but it can be distinguished by the costal patch on the forewing distinctly triangular; the antenna dark brown dorsally, and the hind tibia with dark brown rough scales; the male genitalia with the uncus strongly convex on caudal margin and the aedeagus having a sharply produced apical process dorsally, as long as 2/5 length of the aedeagus.

Description. Male ( Figs. 7A, B ). Wingspan 14.5 mm.

Head: Vertex dark brown, with pale-orange erect scales laterally. Antenna shorter than forewing; basal segment elongated, slightly dilated apically, dark brown on dorsal surface; flagellum serrate, orange white ventrolaterally, dark brown on dorsal surface, with fine cilia ventrally. Labial palpus with 2 nd segment yellowish brown; 3 rd segment as long as 2 nd segment, orange white dorsally, dark brown ventrally.

Thorax: Tegula and thorax dark brown. Hind tibia roughly covered with dark-brown scales, orange white at middle and apex. Forewing slightly dilated distally; ground color dark brown evenly, with an distinct triangular, orange-white costal patch beyond 3/4 of costa; costa slightly arched near base, nearly straight medially, then arched beyond costal patch; apex more or less rounded; termen oblique, nearly straight; fringe concolorous with ground color; venation similar to that of the preceding new species. Hindwing broader than forewing, pale grayish brown.

Abdomen with broad spinous zones on tergites ( Fig. 4E ); a pair of long hair-like pencils between segments VII and VIII; tergite VIII with rounded, sclerotized band-like sclerite.

Male genitalia ( Figs. 7C, D ). Uncus narrowly elongated medially, broadly expanded apically with convex caudal margin. Basal plate of gnathos large, more or less rectangular, much exceeding apex of uncus; median process long, strongly bent downward beyond 2/3 length. Valva slightly broader in basal half; costal margin concave; ventral margin nearly straight in basal half, then strongly upturned, with round apex. Juxta large; length much longer than width, with a pair of triangular lobes at middle, convex on caudal margin. Aedeagus slender, slightly shorter than valva, bent beyond middle, with sharply produced long apical process, as long as 2/5 length of aedeagus; cornuti consisting of a row of short spines, located beyond middle.

Distribution. DR Congo ( Equateur).

Etymology. The species name is derived from the name of one of the preTorodora trilobavious species, barbata Meyrick.
