5. Thubdora trigonoides Park, sp. nov. (Figs. 18 A���G) Type specimens. Holotype: male, Uganda, Kibale Nat. Park, Biol. Field Station, 19���24 xi 2014, LF, leg. W. Mey, gen. slide no. CIS-7252. Paratypes: 1♂, same data as the holotype, gen. slide no. CIS-7009, wing slide no. 7032, COI barcode CBNU062. All types in MfN. Diagnosis. This new species is externally similar to T. ghesquierei, but it is easily distinguished from the latter by the male genitalia: uncus slightly concave on caudal margin and directed outwardly, valva with triangularly elongated cucullus, juxta trapezoidal with short, acute latero-caudal lobes, and aedeagus stout, with a large sac containing numerous spinules medially. Description. Male (Figs. 18 A���D). Forewing length 7.5���8.0 mm. Head: Dark brown dorsally, with pale-orange erect scales laterally. Antenna shorter than forewing; basal segment elongated, pale orange dorsally, dark brown on anterior and posterior surface; flagellum serrate, with fine cilia ventrally, pale orange gradually changing to creamy white towards apex, dark-brown annulations irregularly. Second segment of labial palpus thickened, yellowish brown on outer surface, pale orange on inner surface; 3 rd segment slender, strongly upturned, shorter than 2 nd segment, pale orange all around. Thorax: Notum and tegula dark brown; ventral surface of legs orange white. Forewing costa arched in basal 1/4, strongly oblique beyond 3/4; apex obtuse; termen slightly concave below apex; venation (Fig. 18D) with R 1 strongly bent outwardly near base, distance between R 1 and R 2 twice or longer than that between R 2 and R 3; R 3 and R 4 stalked in proximal half; R 5 absent; M 1 close to R 3+4 at base; M 2 nearly parallel to M 3; M 3, CuA 1 and CuA 2 on a common stalk, 1A+2A shortly forked at base; cell closed; fringe black. Hind wing broader than forewing; apex obtuse; venation with M 2 absent; M 3 and CuA 1 short-stalked; cell closed about middle of the wing. Abdomen (Fig. 18G): No hair-pencils developed in abdominal segment VII-VIII; abdominal segment VIII with heavily sclerotized, crescent anterior margin, with several spines on dorsal surface, not specifically modified on ventral surface. Male genitalia (Figs. 18E, F): Uncus with large, latero-caudal processes; anterior margin concave medially. Basal plate of gnathos with round caudal margin; median process elongated, curved pre-apically. Tegumen with thumb-like lobes bearing setae in distal part, incised in inverted V-shape on anterior margin. Valva expanded near base on costa; ventral margin slightly concave before low corner of cucullus; cucullus narrowed toward apex, strongly upturned, densely setose; apex narrowly produced. Juxta trapezoidal, slightly broadened distally, with acute latero-caudal processes, slightly convex medially on caudal margin, with a narrow stalk anteriorly. Vinculum band-like, triangularly produced anteriorly. Aedeagus stout, broad at base, gradually narrowed towards apex; apex sharply produced; cornuti consisting of two different-sized bundles with numerous spines. Female unknown. Distribution. Uganda (Kabarole Distr.). Etymology. This species name is derived from the Greek trigono (= triangular), referring to the triangularly elongated cucullus of the male genitalia, with a Greek superlative ending - oides.
