( Figs. 21, 21a, 22, 23, 24, 24a )

Type. Holotype: ♂, Cameroon, Efulen, H.L. Weber, Acc. 6257; Aug. 14 1918, gen. slide no. CIS-6839.

Diagnosis. Netioseus cupripennis sp. nov. is characterized by the second segment of labial palp thickened, with long, bushy orange-white hairs above as well as the following new species, but it can be distinguished from the latter by its larger size (18 mm vs. 11 mm), and two features of the male genitalia, namely a rounded cucullus and the very thick phallus.

Description. Male ( Fig. 21, 21a ): Wingspan 18 mm. Head covered with rough orange-white scales dorsally. Antenna longer than forewing; basal segment elongate, about 1.5 times diameter of compound eye, thickened beyond middle, orange white on dorsal surface, sparsely specked with brown scales on ventral surface; flagellum orange white throughout, without distinct annulations. First segment of labial palpus about 1/2 length of 2nd segment, orange white, thickened toward apex; second segment thickened, with long, bushy orange-white hairs above which are longer than the segment; 3rd segment as long as 2nd segment tufted with shorter orange-white hairs dorso-laterally ( Fig. 21a ). Tegula and thorax damaged, lacking scales. Hind tibia with black band at middle and distal end; first tarsus with black scales basally and apically ( Fig. 22 ). Forewing elongate, slightly broadened distally; ground color pale orange, with irregularly scattered pale brown scales; costa slightly concave medially; discal stigma weakly developed at middle of cell; apex obtuse; termen oblique; venation as described for the genus. Hindwing pale orange, paler than forewing; costa slightly protruded at end of vein Sc; apex produced; termen sinuate; venation ( Fig. 23 ) with Rs and M1 short-staked; M2 absent; M3 coincident with CuA1; cell weakly closed. Abdomen without zones of spines on tergites, but with some deciduous minute spines. Female unknown.

Male genitalia ( Figs. 24, 24a ): Basal lobes of uncus small, ovate. Gnathos with rather small median process, connected with a ring-shaped plate near base. Tegumen large, broadened anteriorly. Costal bar connecting tegumen and valva simple, without median angle. Valva extremely broad at base, then narrowed, deeply concave in costa medially, with a linear ridge from middle of basal part of valve, extended to cucullus, and a row of long bristles arising from base of ridge to inner margin; ventral margin strongly protruded in basal 1/4cucullus rounded distally, densely setose in lower part, with round outer margin; sacculus broadly developed, short. Vinculum broad with round apices. Juxta large, shield-shaped. Phallus thick, as long as valva, with a large sac containing numerous minute spinules in vesica.

Distribution. Cameroon.

Etymology. The species name is derived from the Latin, cuprum (= copper) + penn (= wing, feathered), referring to the forewing ground color.
