sp. nov.

3. Dragmatucha galbinea Park , sp. nov.

( Figs 3 View FIGURE 3 A–H)

Type material. Holotype: male, Uganda, Kasese Distr., Kibale Nat. Park, 19–24 xi 2014 [UTM:] 36N TF 0582 6208, 1,500 m, Leif Aarvik & Knud Larsen; gen. slide no. CIS-7190; COI barcode CBNU084, in NHMO . Paratype: 1♂, Western, Kibale Forest, Kanyawara 1,520 m, 0°33′39″N 30°21′27″E, 22 x 2014, leg. D.J.L. Agassiz; gen. slide no. CIS-7189, in NHMUK GoogleMaps .

Diagnosis. This species is superficially similar to D. saltualis sp. nov., but it can be distinguished from the latter by the postmedian band missing or poorly developed on the forewing; and the male genitalia with sharply produced apex of the cucullus, and juxta with heavily sclerotized median process on the caudal margin. It is also differentiated by the DNA sequence data using COI barcode (with 12.6% distance between them).

Description. Male ( Figs 3A, C View FIGURE 3 ). Wingspan 19.0 mm. Head: Covered with yellowish white appressed scales dorsally. Antenna slightly shorter than forewing; basal segment elongated, broadened distally, dark brown dorsally and yellowish white ventrally; flagellum pale yellow throughout, without distinct annulations, finely ciliate. Second palpomere of labial palpus thickened, arched, yellowish brown on outer surface, yellowish white on inner surface; 3 rd palpomere slender, strongly upturned, as long as 2 nd palpomere. Thorax: Tegula yellowish brown, covered with dark brown scales in anterior 1/3; thorax also yellowish white, covered with dark brown scales anteriorly. Hind tibia roughly scaled dorsally with strong setae medially; yellowish white on outer surface. Forewing ground color yellowish brown, with well- developed, rectangular, yellowish white antemedian band; postmedian band zigzagged or invisible; costa nearly straight, oblique beyond 2/3; apex more or less obtuse; termen slightly concave beyond apex; venation similar to that of the preceding species. Hind wing evenly yellowish white, venation also similar to that of the preceding species. Abdomen ( Fig. 3H View FIGURE 3 ): Spinous zone on dorsal surface with strong spines; sternite VIII not modified.

Male genitalia ( Figs 3 View FIGURE 3 D–G): Uncus elongate, slender, as long as length of tegumen, slightly exceeding apex of basal plate of gnathos. Basal plate of gnathos triangularly acute at apex; median process rather short, broad basally, strongly bent beyond 2/3, with sharply pointed apex. Tegumen weakly sclerotized, rather short, deeply concave on anterior margin. Valva broad, elongated; costa slightly expanded near base, then oblique; ventral margin slightly convex medially; cucullus foot-shaped, densely setose, with acute apex. Juxta with heavily sclerotized, triangular median process on caudal margin, vertically ridged centrally. Aedeagus stout, longer than uncus + tegumen, produced apically; cornuti consist of three patches of spinules in distal part.

Female unknown.

Distribution. Uganda (Kibale Nat. Park).

Etymology. This species name is derived from the Latin, galbinus (= yellow) with a Latin adjective suffix, - inea, referring to the yellowish white band on the forewing.
