(Figs. 18 A–E)

Ptilothyris loxocasis Meyrick, 1938: 17 . TL: DR Congo. [RMCA].

Diagnosis. Male (Figs. 18A, B). Ptilothyris loxocasis has superficially a little different characters from its allies of the genus Ptilothyris, by having the forewing more or less short with an oblique, broad, orange-white fascia medially, and the antenna not distinctly pectinate. However, the male genitalia dissected from the type in the RMCA matches well to those of the genus.

Male genitalia (Figs. 18C, D). Uncus broadened caudally with a median protrusion. Basal plate of gnathos with broadly developed median lobe and small lateral lobes; median process large, strongly curved beyond 2/3. Juxta large, with slender, digitate process on anterior margin, lacking caudal lobes. Phallus slender, shorter than valve, apically extending dorsal margin heavily sclerotized, with round apex; cornuti consisting of two short lows of spines in apical area.

Material examined. [RMCA]: 1♂ (lectotype hereby designated), DR Congo, TYPE, Pt. loxocasis M.; Ex- Typis; P 149; R DET. 4080 N; MUSÉE DU CONGO, Burunga (2000), W.
