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 : 465

Torodora lichanosa Park & De Prins , sp. nov.

( Figs. 10 A–D)

Types. Holotype: male, Musée du Congo, [Katanga], Lubumbashi , xii.1938, Ch. Seydel, gen. slide no. CIS-7231/ Park, in RMCA . Paratype: 1♂ Musée du Congo, [Katanga], Elisabethville [Lubumbashi], 20.iii.1935, Ch. Seydel, gen. slide no. CIS-7239/ Park, in RMCA .

Diagnosis. The species is superficially similar to T. semnodora and T. amplignathosa sp. nov., but it can be distinguished by the weakly developed costal patch on the forewing, M 3 and CuA 1 stalked, whereas in amplignathosa , they are separated at base in the hindwing. The male genitalia are easily differentiated from those of T. amplignathosa by the juxta with long, digitate or sword-shaped caudal lobe and the slender, strongly bent, long aedeagus, as long as valva.

Description. Male ( Fig. 10A ). Wingspan 18–20 mm.

Head: Vertex yellowish brown, with same color of lateral erect scales. Antenna slightly shorter than forewing; basal segment elongated, orange white; flagellum serrate, finely ciliate ventrally, with brownish annulations dorsally. Labial palpus upturned; second segment thickened, orange white with dark-brown scales in basal 2/3 on outer surface, orange white on inner surface; 3 rd segment longer than 2 nd segment, sharply pointed apically.

Thorax: Tegula and thorax dark brown. Hind tibia dark brown in basal half on outer surface, then yellowish white beyond; tarsi yellowish white. Forewing slightly dilated distally; ground color pale yellowish brown evenly, with a small, indistinct, elongated yellowish-white costal patch beyond 3/4 of costa; costa slightly arched near base and beyond half; apex obtuse; termen slightly concave beyond apex; fringe concolorous with ground color; venation similar to that of the preceding new species. Hindwing broader than forewing, pale grayish brown; venation with M 3 and CuA 1 shortly stalked.

Abdomen with broad spinous zones on tergites.

Male genitalia ( Figs. 10 B–D). Uncus broad basally, slightly bent medially, more or less stout; apex rounded. Gnathos broad at base, strongly bent beyond 2/3. Valva elongated, broad at base; costa abruptly bent downward near base, then concave; ventral margin nearly straight near to middle; cucullus elongated, narrower toward apex, with rounded ventral margin and concave costal margin, densely haired on surface; sacculus narrowly presented. Juxta semi-ovate, with a large, long, digitate median process and short, triangular lateral lobes on caudal margin. Vinculum narrow, banded. Aedeagus slender, strongly bent near basal 1/3, as long as valva, slightly broad at base, then nearly parallel sided; cornuti consisting of a row of short spines, about 1/3 length of aedeagus, located beyond basal 2/3.

Distribution. DR Congo (Katanga).

Etymology. The species name is derived from the Greek, lichanos (= finger), referring to the finger-shaped juxtal median lobe in the male genitalia.
