8. Thubdora mirinae Park , sp. nov.

( Figs. 9 A–F)

Type specimen. Holotype: male, Uganda, Mpigi, Mpanga Forest , 25–30 xi 2014, LF, leg. W. Mey; gen. slide no. CIS-7074, COI barcode CBNU061, deposited in MfN.

Diagnosis. The male genitalia are similar to those of T. cameroona Park, 2018 ( Figs. 9 G–I), but can be distinguished from the latter by the ventral margin of valva deeply emarginated prior to lower corner of cucullus; cucullus broader and less elongated, with more oblique outer margin distally; juxta broader distally, with wider distance between caudal processes; aedeagus stouter; cornuti consisting of two adjacent, elongated bundles of short scales dorsally and a cluster of variable lengths of spines ventrally ( Fig. 9E ), unlike a bundle of long, hair-like scales in T. cameroona ( Fig. 9H ).

Description. Male ( Figs. 9A, B ). Forewing length 7.5 mm. Head: Vertex yellowish brown, with yellowish- white erect scales laterally. Antenna with basal segment elongated, slightly dilated distally; flagellum serrate, orange white, broken off beyond middle in both antennae. Second segment of labial palpus ( Fig. 9B ) thickened, sabershaped, orange grey, speckled with dark-brown scales on outer surface, dark brown dorsally; 3 rd segment slender, strongly upturned, as long as 2 nd segment, light orange, sharply pointed apically.

Thorax: Notum and tegula yellowish brown. Hind tibia greyish orange white dorsally, with rough scales above. Forewing ground color yellowish brown, irregularly scattered with dark-brown scales; costa arched beyond 2/3, oblique to apex; apex slightly produced; termen oblique; fringe concolorous with ground color, with narrow, orangewhite basal line. Hind wing dark brown.

Abdomen ( Fig. 9F ): A pair of long hair-pencils in segment VII; sternite VIII medially extended with a very slender, aristate, apically bifurcated stalk anteriorly; caudal arms directed outwardly. Male genitalia ( Figs. 9 C–E): Uncus slightly broadened distally, about 1/2 the width of basal plate of gnathos, with convex caudal margin, reach- ing caudal margin of basal plate of gnathos. Basal plate of gnathos with rounded caudal margin; median process broad at base, narrower toward apex, curved downward at nearly a right angle beyond 2/3, sharply pointed apically. Tegumen weakly sclerotized, deeply incised in V-shape medially on posterior margin and anterior margin. Valva slightly expanded in basal 1/4 of costa; cucullus densely setose, upturned, convex medially on ventral margin, with round apex. Juxta large, shield-shaped, with small triangular lateral processes; caudal margin convex; anterior margin with distinctly acute median process. Vinculum narrow, band-like. Aedeagus stout, shorter than valva, about 3/5 the length of valva, sharply produced apically; cornuti consisting of two overlapped leaf-like bundles of scales and a cluster of variable length of spines in distal 1/3.

Female unknown.

Distribution. Uganda (Mpigi Distr.).

Etymology. This species name is derived from a Korean word, mirinae , meaning the Milky Way.
