Avatha bubo

Diagnosis. All the remaining species have an extensive black patch antemedially on the forewing and a sort of hooked hieroglyph in black just distal to the end of the cell that extends more narrowly to the costa and dorsum on the postmedial. In bubo and the next species the hook of the hieroglyph encloses a distinctly paler area, and the ground colour generally is fawn with vinous variegation. The distal border of the antemedial black area is approximately straight. See also the next species.

Taxonomic note. This species is often attributed to Hübner, but see Poole (1989). 

The facies and male genitalia of perficiens (= condita) are as in bubo, and hence the taxa are brought into synonymy. A. olivacea Prout stat. & comb. n. flies with bubo in Seram but has features more as in the next species, though it is slightly more robust, the straight distal margin to the forewing hieroglyph is edged white, and the forewing submarginal has a distinctly darker component at the costal end.

It has a greener tinge than bubo and the basal black band of the forewing terminates further from the dorsum. The male genitalia (Fig 103), compared to bubo, have the valve generally more rounded, rather than slightly quadrangular, and with a distinctive small lobe at the centre of the ventral margin; the small distal lobe in the centre of the valve of bubo is lacking in olivacea, and the latter has a distinct excavation over the distal part of the harpe. The aedeagus is shorter in olivacea but the vesica is relatively larger, equal in volume to the aedeagus, and has a less marked curvature to that of bubo when everted.

Geographical range. Sundaland, Sulawesi, Seram.

Habitat preference. The species is infrequent in the lowlands, found in a variety of habitats including disturbed and cultivated areas. One specimen has been recorded from lower montane forest at 1000m.

Biology. The mature larva was illustrated by Kuroko & Lewvanich (1993). It is a speckled and mottled, ‘muddy’, lichenous greenish grey all over, with A1 slightly swollen as in Serrodes campana (see above) and bearing a dorsolateral pair of black-ringed, pale yellow spots. The prolegs appear to decrease in size from A6 forward to A3.

The host plant is Nephelium (Sapindaceae; see also Robinson et al. (2001)), the larva feeding on the flowers and young leaves.
