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
