Genus Asyprocessa Fibiger   , new genus

Type-species: Asyprocessa wapi Fibiger   , new species.

Taxonomic notes. The genus Asyprocessa   contains three known species. Features of the genitalia indicate relationship with the previous genus Abes   , and the following genera, Tantulius   and Asylemissa   . The species of the genus are held together by several unique features described below.

Diagnosis. Imago (external). Wingspan: 8–10 mm; type-species 9 mm.

Labial palps: porrect; second segment brown outside, beige inside, outwards roughly scaled both dorsally and ventrally; third segment 1/3 of second, narrow, beige (apo.).

Head, patagia, tegulae, thorax, and ground colour of forewing: brown or grey suffused with few dark brown scales; ground colour of forwing of one species light yellow.

Forewing: relatively narrow, pointed at apex.

Abdomen: dark grey, with dorsal tuft on basal segment.

Crosslines: indistinct, brown.

Terminal line: well marked by brown interneural dots.

Reniform stigma: tiny or small, white or beige.

Hindwing: grey, with indistinct discal spot.

Underside: forewing light brown; hindwing grey, with discal spot.

Male genitalia. Tegumen: dorsally gradually narrower (apo.).

Vinculum: dorsally reduced to a prominent, narrow, sticklike structure (apo.).

Saccus: short, V shaped.

Valvae: narrow, asymmetrical, basally with processes that almost join medially (apo.).

Sacculus: asymmetrical, long spinelike process on right side, small triangular plate on left side (apo.).

Clasper: barlike, along valva margin.

Ampulla: rather small, asymmetrical, almost as long as wide.

Juxta: small, inconspicuous.

Anellus plate: very small, only visible as a streak dorsad to hole for phallus (apo.).

Phallus: curved to or almost to right angle (apo.).

Vesica: basally with slightly sclerotised plate with spinules (apo.).

Female genitalia. Ovipositor: short, smoothly rounded posteriorly and at corners.

Posterior apophyses: slightly longer than ovipositor.

Anterior apophyses: length 0.75 of posterior apophyses.

7 th and 8 th abdominal segment: strongly fused ventrally, free laterally and dorsally.

Ostium: large, displaced to left.

Antrum: posteriorly very broad, conelike, strongly curved to almost right angle (apo.) (matching shape of phallus).

Ductus bursae: membranous and narrow, 1.5 times length of corpus bursae.

Corpus bursae: globular.

Appendix bursae: arising posteriorly from ductus bursae.

Signum: cross shaped.

Differential diagnosis. Asyprocessa   differs from other Obscurini   species in:

- brown or yellow ground colour;

- crosslines indistinct;

male genitalia, in

- ampulla almost as long as wide;

- prominent saccular spine on right side;

- sacculus on left side small, triangular;

- phallus smoothly curved to or almost to right angle;

female genitalia, in

- 7 th and 8 th segment fused ventrally;

- ostium large, displaced to left;

- antrum posteriorly wide, strongly curved, strongly tapered.

Distribution. Species of Asyprocessa   are known from Thailand, Laos, and Malaysia.
