Lecithocera lusingensis Park , sp. nov. ( Fig. 5 ) urn:lsid:zoobank.org:act: 60A71BAE-C0F8-4B81-8640-6E447C99053B Type specimen. Holotype : Male , “Congo Belge: P.N.U. / [ DR Congo ] Lusinga [in Prov. Haut-Katanga] ( 1.760 m .) / 17-III-1947 / Mis. G. F. de Witte. 55a // gen. slide no. CIS-7161”, deposited in RMCA . Diagnosis. This new species is one of the largest species (wingspan 19 mm ) of the genus in Africa. It is nearly of the same size as L. corythaeola Meyrick, 1931 which was described from Uganda , but it can be distinguished by the 3 rd segment of the labial palpus which is as long as the 2 nd segment (much longer in L. corythaeola ; see Meyrick 1931: 80 ); the forewing with slightly convex termen (straight in L. corythaeola ; see Meyrick 1931: 80 ); the hind wing ground color much paler than forewing, orangish-grey (concolorous with forewing, bronze), with M 3 and CuA 1 stalked for basal 1/3 (M 3 free from CuA 1 in L. corythaeola ; see Meyrick 1931: 80 ). The male genitalia differ from those of all known species in the Afrotropical region by the following: the costal bar of valva bears a triangle median angle (see arrow no. 1 in Fig. 5C ); the basal plate of gnathos elongates (length about twice its width), with a convex caudal margin (see arrow no. 2 in Fig. 5C ); the aedeagus is slender, about 0.1 times slenderer than its length. Description. Male ( Figs 5A, B ). Wingspan 19.0 mm. Head : golden yellow, with light orange, erect scales laterally. Antenna broadened, only with basal part. Second segment of labial palpus thickened, yellow brown on outer surface; 3 rd segment strongly upturned, as long as 2 nd segment, dark fuscous. Thorax : tegula and thorax dark brown. Forewing ground color fuscous, evenly dark brown, without any markings; apex angulate; termen oblique, gently convex; fringe concolorous with ground color; venation with R 5 to apex; M 2 well developed; base of M 3 arising from between base of M 2 and CuA 1+2 ; CuA 1 and CuA 2 short-stalked. Hind wing ground color paler than forewing, orangish-grey; apex angulate; fringe concolorous with ground color; venation with M 2 present; M 3 and CuA 1 stalked for basal 1/3. Abdomen : tergum VII and sternum VIII shown in Fig. 5E . Male genitalia ( Figs 5C, D ): basal lobes of uncus directed outwardly, with rounded apices; caudal margin slightly concave. Basal plate of gnathos elongated, length about twice its width, distally with convex caudal margin (see arrow no. 2 in Fig. 5C ); median process tapering towards apex, strongly bent from beyond 2/3. Valva broad basally; costal bar with triangular median angle (see arrow no. 1 in Fig. 5C ); cucullus elongated, as long as basal part of valva, slightly convex on both margins; sacculus broadly developed, followed by a crescent, linear plate before cucullus. Juxta jar-shape. Vinculum a broad band. Aedeagus rather slender (width about 0.1 times its length), broadened in basal 1/3; cornuti consisting of 3–4 horn-shaped spines. FIGURE 5. Lecithocera lusingensis Park , sp. nov. , male holotype: A, adult with label; B, head with labial palpus; C, genitalia, slide no. CIS-7161 (with arrows nos. 1 and 2 pointing to the costal bar of valva and elongated basal plate of gnathos, respectively); D, aedeagus; E, abdominal segments VII–VIII (superimposed terga and sterna). Female unknown. Distribution. DR Congo (South-East: Prov. Haut-Katanga). Etymology. This species name is derived from the type locality, Lusinga, Prov. Haut-Katanga, DR Congo . An adjective in the nominative singular.
