Donda Moore Type species: eurychlora Walker, India to Peninsular Malaysia. This and the next genus have very similar facies but differ in characters of the male abdomen. Typical Donda have the forewing markings with fewer elements than in Belciana Walker, but on the same theme of black fasciation on green ground with some white components, and blocks of brown at the apex, subbasally on the tornus and at the dorsum. The hindwings are pale yellow with a dull brown border. The male antennae are filiform, invested with very short setae that are evenly and densely distributed. The clypeofrons is scaled in both genera. In the male abdomen, the eighth sternite has long lateral rods and shows some vestiges of the framed corematous condition. The tergite is triangular, broader posteriorly, and lacks apodemes. In the genitalia, the tegumen has a distinct peniculus, but there is no obvious paratergal sclerite. The uncus is simple, with an apical spur. The valves lack coremata and are much more complex than in Belciana, robustly sclerotised, with both the apex and sacculus terminating in slender processes, with two shorter ones in the cleft between these. The juxta is a broad plate that is linked with the valve sacculus on each side by a narrow, angled ridge. The aedeagus has one or more reversed spines apically. The vesica is a swollen tube with a diverticulum relatively distally that bears spines. The female genitalia (sailendra Kobes) show the distinctive features of Belciana (see below) except the ductus and basal part of the corpus bursae are broader and more extensively sclerotised and corrugated. There is one further species restricted to the Indian Subregion and the Sundanian one described below. The type species extends to Peninsular Malaysia (Barlow, 1982). Bell (MS) described the larva of the type species. It is cylindrical in shape, with all prolegs fully developed. The head is a light pinkish orange, with ventral parts black. The surface is rugose, with the rugosities pink and the interstices yellow. The body surface is glossy, and the setae are long, black, white‑tipped, and arise from large, conical tubercles that are pale yellow. The spiracles are pinkish white. The body surface is a light, watery mauve, almost colourless, with some transverse yellow lines as well as the yellow tubercles, and sometimes there are black spots. The larva turns a light orange colour, with the head red, prior to pupation which takes place in a silken cocoon incorporating detritus on the soil surface. The host plants are Bombax (Bombacaceae) and Trema (Ulmaceae). |
