description: Netioseus acidodes Park, sp. nov.
(Figs. 25, 25a, 26, 26a)
Type. Holotype: ♂, Cameroon, Efulen, H.L. Weber, Acc. 6257; Aug. 14 1918, gen. slide no. CIS-6860.
Diagnosis. Netioseus acidodes sp. nov. is similar to the preceding new species, N. cupripennis sp. nov., in the possession of long, pale orange hairs on the labial palpus dorsally (Fig. 25a), but it can be distinguished from the latter by having a black scale-tuft at the basal segment of the antenna ventro-apically that is shorter than the segment. A similar scale-tuft is present in the genus Paniculata gen. nov.
Description. Male (Figs. 25, 25a): Wingspan 11 mm. Head covered with rough orange-white scales dorsally. Antenna longer than forewing; basal segment elongate, thickened towards apex, orange white on dorsal surface, with a black scale-tuft ventrally at apex that shorter than the segment (Fig. 20a), creamy white on ventral surface; flagellum orange white throughout, without distinct annulations. First segment of labial palpus less than half as long as 2nd segment, orange white, thickened toward apex; second segment of labial palpus very long, thickened, with long, orange-white hairs above as long as respective segment, creamy white ventrally; 3rd segment slender, about half length of 2nd segment, with hairs similar to those of 2nd. Tegula and thorax orange white. Hind tibia lost. Forewing more or less elongate-ovate, with narrowly pointed apex; ground color orange white, with brown scales irregularly scattered in distal 1/3 and in lower part of wing; costa gently arched; stigma absent in cell; apex sharply produced; termen oblique; venation similar to that of preceding species, but R3 free in forewing. Hindwing ground color orange white, as wide as forewing; cell ca.1/3 length wing; venation with Rs and M1 very short-stalked; M3 free and close to CuA1 at base. Female unknown.
Male genitalia (Figs. 26, 26a): Basal lobes of uncus broad, ovate, with dense setae, incised medially on caudal margin. Gnathos with very small median process, heavily sclerotized, as long as basal lobe of uncus. Tegumen densely setose on dorsal surface; dorsal surface slightly incised distally. Costal bar connecting tegumen and valva band-shaped, with sharp median angle. Valva extremely broad at base, more than twice width of cucullus; costa deeply concave medially; ventral margin forming right angle at 1/5, with a bundle of long setae, then slightly concave; a crescentic ridge located in lower part of valve; cucullus elongate, with gently concave costal margin, protruded before middle on ventral margin, with a comb-like row of fine setae located around lower corner of cucullus, followed by short peg-like setae along ventral margin beyond; apex rounded; sacculus weakly developed. Vinculum broadly developed, with round apices. Juxta weakly developed, with semicircular protrusion on anterior margin medially. Phallus stout, as long as valva, strongly bent medially, with a long band bearing numerous minute spinules medially. Abdomen without zones of spines on tergites, but with some deciduous minute spines.
Distribution. Cameroon.
Etymology. The species name is derived from the Greek, akis (= point, beak) + odes (a Greek suffix denoting resemblance), referring to the shape of the forewing.
