description: 6. Ptilothyris vokaensis Park, sp. nov.
(Figs. 9 A–H)
Type specimens. Holotype: male, Congo Republic, Pool Region, Voka 04-405, 14-41E, 620 m, 25–30 May 1993, J. Rawlins, R. Davidson, G. Onore, D. Schlitter, gen. slide no. CIS-5626. Paratype: 1♂, same data as holotype, gen. slide no. CIS-6956. Types are deposited in CMP.
Diagnosis. Ptilothyris vokaensis is externally similar to P. purpurea Walsingham and the different characteristics between two species are noted in the diagnosis of P. purpurea. The male genitalia can be distinguished by the juxta with spine-like caudo-lateral processes in P. purpurea, which are absent in P. vokaensis sp. nov. It is also distinguished from P. porphyrea Ghesquière by the hind wing with purplish grey fringe along inner margin throughout; in P. porphyrea, the hind wing has orange fringe medially. The hair-pencil in the abdominal segments between VII and VIII of P. vokaensis is longer than that of P. porphyrea.
Description. Male (Figs. 9 A–C). Forewing length 9.5–10.0 mm.
Head: Dark purple dorsally, with light-orange, erected scales laterally. Antenna (Fig. 9B) strongly bipectinate with long flagellomeral branches, dark purple in basal 3/5, orange white beyond, with gradually shortened flagellomeral branches. Labial palpus (Fig. 9C) with 2 nd segment thickened, rather flattened, saber-shaped, light orange all around; 3 rd segment slender, as long as the 2 nd segment, speckled with black scales on outer surface; apex acute, black.
Thorax: Notum and tegula dark purple. Hind tibia partly descaled, somewhat similar to that of P. pilosa. Forewing ground color dark purple; antemedian fascia in basal 2/5 distinct, more or less elongate-quadrate; postmedian fascia broadly suffused; costa slightly convex in both basal 1/4 and distal 1/4, otherwise nearly straight medially; apex obtuse; termen slightly oblique; cell closed; venation as in the description for the genus. Hind wing broader than forewing, same ground color as in forewing, with quadrate hylane patch.
Abdomen (Fig. 9H): Densely spinous on tergites; with a pair of long hair-pencils along anterior margin of segment VIII, about 1.5 times longer than the length of segment VII (Fig. 9 H-?); sternite VIII with narrow, gently concave, band-like sclerite along anterior margin. Female unknown.
Male genitalia (Figs. 9 D–G) with uncus broadened distally, fan-shaped, moderately emarginated at middle on caudal margin, with slightly produced lateral lobes. Gnathos with median lobe semiovate, much longer than lateral ones (Fig. 9 D- ©); median process gently bent near middle and strongly bent downward sub-apically. Valva elongate; costa slightly expanded near base, then slightly concave; cucullus elongate, slightly curved inwards apically. Ventral plate of juxta oblique, slightly concave caudally, with right lobe developed; dorsal plate with triangular plates on anterior margin laterally (Fig. 9G). Vinculum a band, narrow, heavily sclerotized. Phallus slightly shorter than valva, curved near basal 1/3; cornutus with a row of minute spines.
Distribution. Congo Republic.
Etymology. The species epithet is named after the type locality.
