Calymniops Hampson Type species: trapezata Moore, Sri Lanka, Sumatra (HS / K). Though having a strong vein M2 in the hindwing, the narrow forewings of this genus are reminiscent of those of trifine genera such as Dyrzela Walker. Dyrzela is best assigned to the Bagisarinae (Holloway, 1998, and see above), though it has been covered under Amphipyrinae in this series (Holloway, 1989), together with another bagisarine genus, Chasmina Walker. Indeed, the type species, trapezata, has a structure of the eighth segment in the male that is identical to that illustrated by Holloway (1989: fig 37) for D. roseata Holloway, particularly the unusual thickening within the sternite with lateral bands and a central ovate area that forms a cruciform structure with the anterior margin and its central apodemes. The tergite has something of the drink can ring‑pull structure noted by Holloway (1989) for Dyrzela. Hence Calymniops is probably also bagisarine, closely allied to Dyrzela, and would therefore be predicted to have a larva with appendiculate crochets that feeds on Malvales. The male antennae are strongly fasciculate. The labial palps are long, slender, including the third segment, and upcurved. The forewings have the dorsum obtusely angled subdorsally, uniform brown or grey, crossed by three fine darker fasciae, but mostly lacking the dark patch subapically in the costa of all Dyrzela. The hindwings of the male have longer androconial scales, though these are restricted to the dorsum and slightly lobed tornus in the type species. Characteristics of the male abdomen have been mentioned above; in the two Bornean species the eighth segment is more elongate, but the basic structure is similar. The structure of the male genitalia is also similar to that of Dyrzela, with a narrow saccus in two of the three species, albeit a short one in the type species, and various processes from the base of the rather narrow valves that, as in Dyrzela and Chasmina, lie closely adjacent to the tegumen. In the female genitalia, the ovipositor lobes are approximately semicircular with apodemes slightly shorter than themselves. The eighth segment is almost a complete ring, with only a very narrow groove dividing it ventrally; its apodemes are shorter than those of the ovipositor. The ostium is associated with its anterior margin. The ductus bursae is about as long as the seventh segment, with the basal quarter to third sclerotised into an antrum. The corpus bursae has an approximately equivalent appendix bursae that is coiled; the corpus bursae, when long, may also be coiled (see below). This appendix bursae provides a major distinction from Dyrzela. There is no signum. The genus consists of the type species and the two new ones described below. |
