16. Sorolopha stygiaula (Meyrick, 1933)

Argyroploce stygiaula Meyrick, 1933: 419 (3, Ƥ, Indonesia: Java) Olethreutes stygiaula: Clarke, 1958: 552, plate 275 figs. I-Ia (wings, 3 genit.). Eudemis (Acanthothyspoda) stygiaula: Diakonoff, 1967: 52 .

Sorolopha stygiaula: Diakonoff, 1973: 97, figs. 151, 153, 154, 158, 159 (3, Ƥ genit.).

Diagnosis. This species is similar to S. bruneiregalis Tuck & Robinson, 1994 in male genitalia, but can be separated from the latter by the following characters: the valva protruding slightly at costa close to base, bearing one thorn or a group of three thorns at costal 2/5 and a short thorn on ventral margin at base of the cucullus; the cucullus slender, not dilated apically. In S. bruneiregalis, the valva has a prominent and blunt costal angulation close to base, and possesses no thorns on the costa and ventral margin of the cucullus; and the cucullus is dilated apically. In our specimens, the valva has only one longer thorn at costal 2/5, different from that in the holotype from Java, Indonesia, which has a group of three thorns in this position.
