Furcalis efulenica Park , sp. nov.

( Figs. 29, 31, 31a–b )

Type. Holotype: ♂, Cameroon, Efulen, H.L. Weber, Acc. C.M. 6122; Apr. 20 1916, gen. slide no. CIS-6874 . Paratype: 1♂, same data as holotype, Apr. 25 1916, gen. slide no. CIS-6843.

Diagnosis. The male genitalia of F. efulenica are similar to those of F. triodonta , but it can be distinguished by the more or less triangular cucullus and the single, brush-shaped median process on ventral margin, bearing about 10 apical setae.

Description. Male ( Fig. 29 ): Wingspan 14–16 mm. Head brownish yellow dorsally, with erect, pale orange scales laterally. Antenna longer than forewing; basal segment elongate, relatively short, brownish yellow dorsally, pale orange ventrally; flagellum orange white, with distinct dark brown annulations throughout. Second segment of labial palpus thickened, densely covered with dark-brown scales on outer surface, orange white on inner surface; 3rd segment slender, as long as 2nd segment, concolorous with 2nd in basal 2/3, then orange white in apical 1/3. Tegula and thorax brownish yellow. Fore- and middle legs dark fuscous ventrally. Hind tibia with shiny orangewhite hairs above. Forewing elongate, ground color rather uniform pale brownish orange, with small orange-white patch at distal 4/5 on costa and similar patch just before apex; costa orange white along anterior margin; apex obtuse; termen oblique; fringe brownish yellow with orange-white basal line from before apex to tornus; cell about 2/3 length of wing, closed with weak cross vein; venation similar to that of F. triodonta . Hindwing broader than forewing, with hyaline expansion from base to beyond middle; ground color paler than forewing; apex sharply produced; termen slightly concave before middle, oblique. Female unknown.

Male genitalia ( Figs. 31, 31a ): Basal lobes of uncus more or less quadrate, densely covered with long setae; caudal margin slightly concave medially. Gnathos slender, about half length of tegumen, narrowed toward apex, bent apically. Tegumen as long as vinculum, with numerous setae on dorsal surface. Costal bar with gently arched dorsal margin, not angled medially. Valva broadest at base, with long hairs in lower half; ventral margin with brush-shaped process, bearing about 10 spines apically; cucullus more or less triangular with nearly straight costal margin, gently convex on outer margin, dense setose on surface; apex obtuse; sacculus sclerotized, extended to median process. Juxta shield-shaped, slightly concave on caudal margin with triangular latero-caudal lobes, triangularly projected on anterior margin medially. Vinculum broad with round apices. Phallus broad at base, as long as valva, slightly bent medially, ventral margin produced apically; cornuti consisting of more than 10 different sizes of spines. Abdominal segment VII with long hair-pencil; sternite VIII deeply emarginated on caudal margin medially, with about each 5–6 long bristles on each side along margin ( Fig. 31b ).

Distribution. Cameroon.

Etymology. The species name is derived from the type locality.
