"Aquis" orbicularis

"Aquis" orbicularis

This is a variable species with some resemblance in size, shape, colour and markings to the previous two, but the forewing pattern is more in blocks, diffu
sely defined, but often with a curved transverse fscia in the medial area.

Taxonomic note. The male genitalia indicate this species is misplaced
in Aquis, with a strange, shouldered tegumen and uncus, a scaphial structure similar to that of some Ariolicini, and a complex valve with a rather convolute saccular area and, more distally, a longitudinal zone of peg-like setae, another ariolicine feature. There is a narrow and prominent saccus. The female has very short ovipositor lobes, twice as deep as long, rectangular. The eighth segment is also short, as are the ductus and bursa, the latter rather triangular and containing a horseshoe-shaped, spined signum that extends over most of its length. “A.” crenulata Bethune-Baker stat. rev. (= babooni Bethune-Baker) is a distinct but related species from New Guinea. The uncus is triangular rather than trifid, and the valves are broader, with a rounded distal margin fringed by hairs, the field of peg-like setae central-lateral rather than apical.

Geographical range. Indian Subregion, Peninsular Malaysia, Borneo.

Habitat preference.
The species is never common, but is found in a range of forest types from the lowlands to 1790m.
