Carea Walker

Type species: varipes Walker, Peninsular Malaysia.

Synoym: Dabarita Walker (type s
pecies subtilis Walker, India = angulata Fabricius).

This and the next six ge
nera represent the Carea complex of Holloway (1976), reviewed in more detail by Kobes (1997), who segregated the taxa into more precisely defined genera. His system is mostly followed here, though with the addition of Arrhapa Walker and the inclusion of Lasionotella Warren within the concept of Didigua Walker.

Carea share
s with the next two genera a finely double, transverse (females only in Chora) or gently curved forewing postmedial. This intersects the tornus and cuts off a marginal zone that is often paler than the rest of the wing. The antemedial is single, much less distinct, and strongly oblique. The margin is usually strongly convex in these genera, though the Carea angulata Fabricius complex has it distinctly bifalcate. The forewing colour is usually dull shades of red, orange or rufous brown, sometimes with a vinous tint. The costa of the male valve has a lobe or zone with a dense mass of small deciduous setae.

In the male abdomen the eighth tergite has its basal margin narrowly cleft, the cleft margins thickened and having a series of 5-6 longitudinal grooves on each side; the sternite has a much broader cleft. In the genitalia the uncus is narrow, straight, flanked on each side by projections of the tegumen (weak in the angulata group). The tegumen is elongate, ventrally expanded, overlapping its complex articulation with the vinculum. The valve is elongate, with a lobe on its costal margin bearing a dense brush of ventrally directed setae. The saccus is distinctly square, with a short central protrusion (weaker in the angulata group). The aedeagus vesica is globular, with a cluster of large but slender spines.

The female has a short, slender, unsclerotised ductus, a pyriform bursa with a rather elongate neck that has a distal area of rather convolute sclerotisation from which arises a sausage-like appendix bursae. The distal part of the bursa is spherical, with a rather squat ‘golf tee’ signum.

The larvae are typically careine, as discussed below, and appear to show some preference for Myrtaceae, along with those for the genera to Xenochroa Felder that follow.

The genus consists of typical and angulata groups, the former extending east to New Guinea but the latter not noted beyond Sundaland.
