description: 7. Thubdora latidiscalis Park, sp. nov.
(Figs. 8 A–F)
Type specimens. Holotype: male, Uganda, Kibale National Park, Biol. Field Station, 19–24 xi 2014, LF, leg. W. Mey; gen. slide no. CIS-7027, COI barcode CBNU052, deposited in MfN. Paratypes: 1♂, same data as holotype; gen. slide no. CIS-7016, COI barcode CBNU051, in MfN.
Diagnosis. This species is superficially similar to T. fruticosa Park, sp. nov., but it can be distinguished from the latter by the male genitalia: uncus very broad, as wide as the basal plate of the gnathos; gnathos with the basal plate gently rounded on caudal margin, not strongly convex; juxta with a triangular caudal plate; and aedeagus with variously shaped cornuti.
Description. Male (Figs. 8A, B). Forewing length 9.5 mm. Head: Vertex dark brown dorsally, with orangewhite erect scales laterally. Antenna (Fig. 5B) basal segment elongated, orange white; flagellum serrate, with fine cilia ventrally, orange white with dark-brown annulations weakly developed in basal half. Second segment of labial palpus thickened, saber-shaped, yellowish brown, irregularly speckled with dark-brown scales in basal 2/3, gradually paler toward apex; 3 rd segment strongly upturned, as long as 2 nd segment, brown, acute apically (Fig. 8B).
Thorax: Notum and tegula dark brown. Forewing ground color dark brown uniformly; antemedian fascia inconspicuous; costa slightly arched in basal 1/3 and apical 1/3, costal patch absent; apex obtuse; fringe concolorous with ground color, with narrow, orange-white basal line. Hind wing pale yellowish brown.
Abdomen (Fig. 8F): Sternite VIII narrowly extended posteriorly, with latero-caudal lobes directed outwardly, slightly concave on caudal margin; segment VIII with broad, V-shaped sclerite. Male genitalia (Figs. 8 C–E): Uncus broadened distally, as wide as basal plate of gnathos, slightly concave medially on caudal margin. Basal plate of gnathos with rounded caudal margin; median process strongly curved downward beyond 2/3. Tegumen weakly sclerotized, incised in V-shape anteriorly. Valva elongated, expanded dorsally in basal 1/4 of costa; cucullus elongat- ed, densely setose, upturned, gently arched on ventral margin. Juxta shield-shaped, with large, triangular posterior plate. Vinculum band-like, with more or less flat anterior margin. Aedeagus shorter than valva, about 4/5 the length of valva, broad basally, narrower toward apex, with more or less acute apex; cornuti consisting of a slightly curved bar apically, an elongate-ovate plate with a slender stalk posteriorly, and a row of short bristles basally.
Female unknown.
Distribution. Uganda (Kabarole Distr.).
Etymology. The specific name is derived from the Latin latus (= broad) plus discus (= plate), referring to the broadly expanded uncus.
