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. FIGURE 18. Thubdora trigonoides Park , sp. nov. : A, adult, holotype; B, base of antenna, holotype; C, labial palpus, lateral view, holotype; D, venation; E, male genitalia, paratype, gen slide no. CIS- 7009; F, aedeagus, same paratype; G, abdominal segments VI–VIII, same paratype. Scale bar for genitalia and aedeagus: 1.0 mm. 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.
