10. Thubdora retusivalva Park View in CoL , sp. nov.

( Figs. 11 View FIGURE 11 A–G)

Type specimen. Holotype: male, Uganda, Kibale Nat. Park, Biol. Field Station , 19–24 xi 2014, LF, leg. W. Mey; gen. slide no. CIS-7033, wing slide no. CIS-7034, deposited in MfN.

Diagnosis. Thubdora retusivalva is superficially similar to T. wooriana Park , sp. nov. with a similar costal patch on the forewing, but it can be distinguished from the latter by the male genitalia with the uncus narrower, the cucullus nearly parallel-sided, the caudal plate of the juxta much smaller, and cornuti consisting of two, large, spinelike bars pointed apically.

Description. Male ( Figs. 11 View FIGURE 11 A–C). Forewing length 8.5 mm. Head: Dark brown dorsally, with orange white erect scales laterally. Antenna ( Fig. 7B View FIGURE 7 ) shorter than forewing, with basal segment elongated, yellowish white dorsally, dark brown laterally; flagellum serrate, with fine cilia ventrally, creamy white. Second segment of labial palpus thickened, yellowish brown on outer surface, yellowish white on inner surface; 3 rd segment slender, strongly upturned, as long as 2 nd segment, orange white dorsally, dark brown ventrally, sharply pointed apically.

Thorax: Notum and tegula dark brown. Forewing ground color yellowish brown, scattered with dark-brown scales irregularly; costa arched beyond 2/3, oblique to apex, with orange-white crescent costal patch beyond 3/4; apex obtuse; termen oblique; fringe concolorous with ground color, with narrow, orange-white basal line; venation ( Fig. 11C View FIGURE 11 ) with R 1 strongly bent outwardly near base, R 3 and R 4 stalked for 2/5, R 4 reaching before apex; R 5 absent; M 1 close to R 3+4 at base; M 2 arising from lower corner of cell; M 3 parallel to M 2; M 3, CuA 1 and CuA 2 on a common stalk, 1A+2A shortly forked at base; fringe with narrow, orange-white basal line, dark brown beyond. Hind wing pale brownish grey; apex obtuse; venation with M 2 absent; M 3 and CuA 1 stalked for basal 1/4; cell closed before middle of the wing.

Abdomen ( Figs. 11F, G View FIGURE 11 ): Spinous zone on segment VI vertically elongated; with a pair of long hair-pencils between segments VII and VIII; sternite VIII narrowly extended posteriorly, forming a long stalk; tergite VIII heavily sclerotized, with U-shaped anterior margin. Male genitalia ( Figs. 11D, E View FIGURE 11 ): Uncus narrow, slightly broadened distally, about 1/3 the width of basal plate of gnathos, convex on caudal margin. Basal plate of gnathos rounded on caudal margin, reaching apex of uncus; median process broad at base, narrower toward apex, curved downward beyond 2/3, sharply pointed apically. Tegumen weakly sclerotized, incised in V-shape medially on posterior and anterior margin. Valva slightly expanded in basal 1/4 of costa; cucullus nearly parallel-sided, densely setose, upturned, with broad apical margin. Juxta large, more or less ovate, broader anteriorly, with vertical ridge centrally; caudal margin with small, triangular median plate and small triangular lateral processes; anterior margin sharply produced medially. Vinculum narrow, band-like. Aedeagus shorter than valva, about 3/5 the length of valva, slightly curved basally, sharply produced apically; cornuti consisting of two, large, spine-like bars, pointed apically, located in distal 1/3.

Female unknown.

Distribution. Uganda (Kabarole Distr.).

Etymology. This species name is derived from the Latin retusus (= blunted, rounded) + valva.
