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 : 459

Thubdora kapangaensis Park & De Prins , sp. nov.

( Figs. 6 A–D)

Type. Holotype: male, Coll. Mus. Congo, [Katanga], Kapanga , xii.1932, F.G. Overlaet, gen. slide no. CIS-7242/ Park, in RMCA.

Diagnosis. The new species can be distinguished from all the preceding new species by having a larger, distinct triangular orange-white costal patch on the forewing and the lateral erect scales of head light orange; and especially by the male genitalia with a broad valva, a less elongated cucullus, and a short, stout, and nearly straight aedeagus.

Description. Male ( Figs. 6A, B ). Wingspan 14 mm.

Head: Vertex dark brown, with light- orange erect scales laterally. Antenna shorter than forewing; basal segment elongated, light orange, slightly dilated apically; flagellum serrate, light orange, paler toward apex, finely ciliate ventrally. Labial palpus strongly upturned; 2 nd segment thickened, pale orange, shiny on both sides, dark brown ventrally; 3 rd segment as long as 2 nd segment, pale orange, but fuscous ventrally, sharply pointed apically. Thorax: Tegula and thorax dark brown. Hind tibia pale orange, shiny all around; tarsi orange white. Forewing slightly dilated distally; ground color dark brown evenly; costal patch large, triangular, orange-white; costa arched in basal 1/3, then nearly straight to costal patch; apex rounded; termen oblique, nearly straight; fringe concolorous, with indistinct orange-white basal line. Hindwing broader than forewing, pale grayish brown; fringe concolorous, with narrow orange-white basal line.

Male genitalia ( Figs. 6C, D ). Uncus with truncate caudal margin. Basal plate of gnathos with strongly convex caudal margin, exceeding to apex of uncus; median process relatively short, strongly bent downward beyond 2/3. Valva broad basally; cucullus relatively broad, not strongly upturned, densely haired on inner surface; costal margin slightly concave medially; ventral margin protruded basally; apex rounded. Juxta broad, semi-ovate with strongly convex caudal margin. Aedeagus nearly straight, about 2/5 length of valva; cornuti consisting of a bundle of setae, located beyond middle; apex rounded.

Distribution. DR Congo (Katanga).

Etymology. The species name is derived from the type locality.
