Thubdora neobarbata Park & De Prins

sp. nov.

Thubdora neobarbata Park & De Prins  , sp. nov.

( Figs. 7View FIGURE 7 A–E)

Types. Holotype: male, Coll. Mus. Congo, [ Equateur], Flandria , 10.ix. [19]35, J. Ghesquière, gen. slide no. CIS- 7157/ Park, in RMCAAbout RMCA  . Paratype: 1♂, Coll. Mus. Tervuren, Kinshasa (Lovanium) 14.xii.1966, Dr. J. P. Bastin, gen. slide no. CIS-7244/ Park, in RMCAAbout 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, BView FIGURE 7). 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. 4EView FIGURE 4); a pair of long hair-like pencils between segments VII and VIII; tergite VIII with rounded, sclerotized band-like sclerite.

Male genitalia ( Figs. 7C, DView FIGURE 7). 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.
