17. Ptilothyris neuroplaca Meyrick, 1933 (Figs. 19 A���F) Ptilothyris neuroplaca Meyrick, 1933: 359 (Idiopteryx). TL: Congo, Belg. [NHMUK]. Diagnosis. Female (Figs. 19A, B). Forewing length 9.0 mm. Ptilothyris neuroplaca is distinguished from other members of the genus by the pale-orange head and the same ground color of the forewing. The forewing has two, dark-fuscous, transverse streaks, one at base, the other as a wide postmedian fascia; outer streak 2/5 the length of forewing in width, with pale-orange branched lines, and the hind wing ground color is dark brown, with orangewhite vertical streak preapically on costa. Female genitalia (Figs. 19 C���E). See also Clarke, 1965: pl. 107, Figs. 1���1c. Abdominal sternite VIII broadly and shortly emarginated, with more or less triangular lateral lobes. Apophyses anteriores long, about 2/3 the length of apophyses posteriores. Lamella antevaginalis large, isosceles trapezoidal, weakly sclerotized. Ductus bursae narrow, long, about three times the length of corpus bursae; ductus seminalis arising from near middle. Corpus bursae ovate; signum large, roundish, as wide as long. Material examined. [NHMUK]: 1♀ (holotype), Zambia, N. Rhodesia, Congo-Zambesi watershed, 1918, leg. H. S. Evans, gen. slide no. BM-9135/Clarke. Distribution. Zambia. Remarks. Even though the wing color pattern of this species is exceptionally different from other members of the genus, the female genitalia have a prolonged hood-shaped signum which is a common character of the genus Ptilothyris.
