Masca Walker

Type species: abactalis Walker, Singapore.

Phagytra Walker (type species leucogastralis Walker, Java = abactalis).

Both species in the genus (Zilli & Hogenes, 2004) have black and white wing facies as illustrated. The male antennae are ciliate, the legs with small crests of scales that extend to the tarsus; there is a hair-pencil on the hind-tibia. The labial palps are of the standard catocaline type.

In the male abdomen, the eighth sternite is very much broader than the tergite and has a single anterior corema supported by a narrow arc of sclerotisation on that margin that has rods laterally. The main lamina of the sclerite extends posteriorly from the whole width of these structures. The tergite is unmodified. In the genitalia the valve is deeply divided, the saccular part terminating in a much narrower process; its shape is somewhat similar to that in
Brontypena Holland (p. 156). However, it has a long slender corema arising from subbasally on the costal half of the valve, lacking in Brontypena, and the saccus is distinctly narrowed, acute. The aedeagus has two major diverticula, with zones of scobination of varying coarseness.

The female has the ostium between the seventh and eighth segments. The ductus is sclerotised, straight, scrolled on each side. The corpus bursae is an elongated, finely scobinate and partially or wholly corrugated pyriform with a well developed appendix bursae between its base and centre. The corrugation is basally sclerotised in the Australasian species, presumably to accommodate the more massive spining in its aedeagus vesica.
