MATERIAL EXAMINED. — Togo • 1 ♂; “ Togo / Bismarckburg / 22.IX-1.X.92 / L. Conradt S.”; ZIN ; 1 ♀; “ Togo / Bismarckburg / 23.XI-2.XII.92 / L. Conradt S.”; ZIN ; 1♂; “ Togo / Bismarckburg / 9-11.V.93 / L. Conradt S.”; ZIN ; 1 ♀; “ Togo / Bismarckburg / 12- 14.IV.93 / L. Conradt S.”; ZIN .

DIAGNOSIS. — Coryphe-metope margin keel-shaped. Metopial proboscis weakly concave frontally. Fore wings dark brown to black, with rich elongate venation. Phallobase short, aedeagus wide in lateral view, with four narrow subapical processes – three on left side and one on right side. Male anal tube narrowing apically in dorsal view.

DISTRIBUTION. — Central Togo.

DESCRIPTION

Structure ( Figs 2A, B View FIG ; 4A, B View FIG ; 6A, B View FIG ; 7 View FIG )

Coryphe transverse, 1.5 times as wide as long medially, smooth, without carinae, with slightly convex or nearly straight anterior margin ( Fig. 4A View FIG ). Coryphe-metope margin keel-shaped ( Fig. 6A View FIG ). Eyes large, diameter of each eye nearly as large as width of metope between the eyes. Metope, pro- and mesonotum densely covered with traces of larval sensory pits (pustules). Metopial proboscis weakly concave ventrally in frontal view ( Fig. 6B View FIG ). Post- and anteclypeus with distinct median carina. Pedicel slightly flattened laterally, with area of dense setae dorsally ( Fig. 6A View FIG ). Fore wings large, nearly oval, narrowing apically, with 1/3 of its length behind apex of clavus in lateral view ( Fig. 4B View FIG ). Basal cell small, loop-shaped. Radius and median running from the basal cell separately, but nearly from one point. Fore wings with small number of transverse veins.Forewing vein branching sequence: R 5-8, firstly furcating closely to basal cell; M 10-14, firstly furcating closely to basal cell; M 1 and M 2 furcating again in basal wing third – M 2 before M 1; CuA 2-3, furcating at the same point as M 1; CuA 1 and CuA 2 terminating at concave cell behind apex of clavus, CuA 1 sometimes furcating also apically (in one specimen right wing with CuA 2 and left wing with CuA 3). Pcu joint A 1 in apical fourth of clavus. Clavus long, 2/3 of wing length. Hind wings bi-lobed, without cubital cleft and with weak vannal cleft; anterior margin with long and narrow coupling lobe ( Fig. 7A View FIG ). Precostal margin with dense macrosetae at its basal third and with sparse marginal microsetae. Hind wing vein branching sequence ( Fig. 7A View FIG ): R 2, furcating before wing middle; r-m 1; M 1; m-cua 1; CuA 3, firstly furcating at wing middle and CuA 2 furcating apically; cua-cup 1; CuP 1; cup-pcu 1; Pcu 1; A 1 1; A 2 1. Legs not flattened neither foliated. Hind tibia with 9-12 spines apically. First metatarsomere with two latero-apical and 4-6 intermediate spines arranged in an arc apically. Arolium of pretarsus not protruding beyond claw apices, sometimes with notched hind margin (in dorsal view). Dorso-lateral plates of arolium long and narrow.

Coloration ( Fig. 4A, B View FIG )

Metope, pronotum, mesonotum, and fore wings dark brown to black (on fore wings). Head laterally light yellow to light brown and black above brown scapi. Anteclypeus and rostrum yellowish light brown. Pedicels dark brown to black, with green area of setae dorsally. Third segment of rostrum and flagellum dark brown to black. Postclypeus dark brown, sometimes pale laterally. Precostal margins of fore wings and semicircular lobes behind apex of clavus reddish. Hind wings brown to black. Legs greenish brown to dark brown or black, with yellowish light brown trochanters. Apices of leg spines black. Claws dark brown to black. Dorso-lateral plates of arolium dark brown to black. Abdomen light yellow to dark brown.

Male terminalia ( Fig. 8 View FIG )

Pygofer vertically elongate, with right upper angle (below anal tube), hind margins straight, lower margin weakly concave ( Fig. 8A View FIG ). Anal tube short, wide, narrowing apically in a convex margin (in dorsal view) ( Fig. 8B, C View FIG ). Anal column short, 0.3 as long as anal tube. Phallobase short, nearly 0.3 as long as aedeagus, without processes. Aedeagus curved, horseshoe-shaped, asymmetrical, with straight apical part, cylindrical, with small denticles ventrally and laterally. Aedeagus with four subapical horn-shaped narrow processes directed downwards – three on left side (longest one near to ventral surface ( Fig. 8E, c View FIG ), twice shorter one near to dorsal surface ( Fig. 8E, b View FIG ), and smallest one above them at the middle ( Fig. 8E, d View FIG ) and one long (as long as longest left one) on right side ( Fig. 8D, a View FIG ). Style with short apical tooth, large lateral tooth, and distinctly convex hind margin ( Fig. 8G View FIG , hm, at, lt). Connective with widely opened short cup ( Fig. 8D View FIG , cp).
