(Figs. 4A–K)

Type material. Holotype. [Uganda] male, Mpanga Forest, Mpigi, Uganda, 25.–30. XI. 2014 (LF, leg. W. Mey), gen. slide no. CIS-7268, wings slide no. CIS-7407. Paratype. 1♂, same collected data with the holotype, gen. slide no. CIS-7051, wings slide no. KJM0217. All types are in MfN.

Diagnosis. This new species is similar in male superficial and genital characteristics to Torodora efulenensis Park, 2018 and T. planusa Park & De Prins, 2019, respectively known from Cameroon and DR Congo. However, it can be distinguished by the following characteristics of the male genitalia: Basal 2/3 of medial process of gnathos remarkably broader than that of T. efulenensis and T. planusa; cucullus about 2 times longer than basal part of valva in the new species, but cucullus about 1.5 times longer in T. efulenensis and T. planusa; aedeagus stout, bent medially, gradually narrowed distally beyond basal half in the new species, but aedeagus bent at basal 1/3, then narrowed distally, broadly produced in apical part with rounded apex in T. efulenensis, and aedeagus nearly straight, relatively elongated with small crescent sclerite beyond basal 3/ 4 in T. planusa.

Description. Adult (Figs. 4A, B, E–H). Wingspan 12.0–13.0 mm. Head: Vertex yellowish brown with yellowishwhite scales medially. Antenna 0.7 times shorter than forewing, with elongated scape; scape yellowish white with dark brown scales on outer surface; flagellum filiform, not ciliate, yellowish white without annulations. 2 nd segment of labial palpus yellowish white ventrally and dark brown dorsally and basally on outer surface, yellowish white on inner surface; 3 rd segment 1.1 times longer than 2 nd segment, yellowish white with dark brown scales dorsally (Figs. 4E, F). Thorax: Notum and tegula yellowish brown. Forewing ground color evenly yellowish brown, without marking; apex obtuse; termen slightly concave medially; fringe concolorous with ground color; venation (Fig. 4D) with R 1 arising from near basal 3/5 of discal cell; R 2 arising near the upper corner of cell; distance between origins of R 2 and R 3+4+5 2.4 times shorter than that of R 1 and R 2; R 3 stalked with R 4+5 for basal 3/10; R 4 and R 5 stalked for basal half, R 5 reaching slightly beyond apex; M 1 remote from R 3+4+5 at base; M 2 shortly stalked with M 3 at base; CuA 1 stalked with CuA 2 for basal 3/10; 1A+2A narrowly short-forked basally; discal cell closed. Hindwing ground color similar to that of forewing, slightly broader than forewing, with nearly straight costal margin beyond basal 1/3; apex produced; termen oblique, slightly concave medially; fringe concolorous with ground color; venation with M 2 well-developed; M 2 shortly stalked with M 3 at base; M 3 and CuA 1 stalked in basal half; cell weakly closed. Hindtibia yellowish brown in basal half, then yellowish white distally, with yellowish-brown marking on sub-distal end of outer surface (Figs. 4G, H). Abdomen (Fig. 4K): Ventral surface covered with light yellow scales. Spinose zones broadly developed on each I–VII tergite. Sternites weakly sclerotized; VIII sternite simple.

Male genitalia (Figs. 4I, J): Uncus elongated, with pointed apex, reached to apex of basal plate of gnathos. Median process of gnathos remarkably large in basal 2/3, then rapidly narrowed toward apex, strongly bent downward in distal 1/3. Teguman weakly sclerotized, concave into triangular shape on anterior margin. Valva upturned, broad at base, then rapidly narrowed before cucullus, with extended basal costa; cucullus narrowly elongated, densely setose, about 2 times longer than basal part of valva, with rounded apex. Vinculum narrow, heavily sclerotized. Juxta large, shield-shaped, slightly concave on caudal margin, lacking latero-caudal processes. Aedeagus stout, as long as cucullus, strongly bent medially, distal half narrowed; cornutus absent.

Female unknown.

Distribution. Uganda (Mpigi).

Etymology. The species name is derived from the Greek, chryso (= golden) with a Greek suffix, - etes, referring to the golden abdomen on the ventral surface.
