Pantydia Guenée

Type species: sparsa Guenée, type locality not known [Australia].

Synonym: Rhiscipha Walker (type species scissa Walker, Congo). 

Species typical of Pantydia are relatively robust within the tribe, and share a number of facies characters, including a general grey, buff and brown colour with localised black marking. The patagia grade blackish distally to give the effect of a black collar, but this black is not as extensive as in Lygephila Billberg and does not extend to the head. The forewings are extensively speckled and striated darker, but the only clear fascia is a straight, pale, narrow, transverse line that is approximately submarginal. This has more irregular blackish markings immediately basally and distally. there is a more obscure antemedial fascia that can include a small, clearly defined black spot or hieroglyph subdorsally. The reniform may stand out paler amid surrounding dark shading. The hindwings are more uniform, with a broad, darker border and usually a much narrower diffuse dark fascia just basal to it. On the underside, all wings are pale, uniform with broad blackish borders that stop just short of the margin. The male antennae vary, being serrate - fasciculate in the type species, with a nodal swelling at one quarter in capistrata Lucas (Australia, New Caledonia), and ciliate in metaspila Walker, the species recorded from Borneo. The labial palps are of the typical catocaline type.

In the male abdomen, the eighth segment is unmodified or, in the type species, with a single corema at the base of the sternite but without lateral framing. The genitalia do not show asymmetry in the valves but otherwise accord with the tribal characteristics. They have the uncus robust with a ‘ball and claw’ apex, the cleft within it very narrow. There is a scaphium. The valves are simple, narrow, without processes, but with a definite costa. The juxta is an irregular version of the inverted ‘Y’ type. The aedeagus vesica is large with many diverticula and areas of scobination and coarser spining.

The female genitalia (sparsa, metaspila) have the ostium just within the posterior of the reduced and tapering seventh sternite, which is weakly bilobed where it covers the ostium. The ductus is sclerotised in two sections joined by a short membranous part. The more basal is longer in sparsa but shorter in metaspila; the distal part is laterally scrolled in metaspila. The corpus bursae has a distinct appendix bursae that coils into the ductus seminalis, and is rounded in sparsa but narrow, elongate in metaspila. In both, the area adjacent to the ductus is scobinate, more strongly so in sparsa, and there is a small scobinate signum near the apex.

The genus is diverse in Africa (though only
P. scissa may be truly typical), but only P. metaspila Walker occurs widely in the Indo-Australian tropics. Several species occur in Australia (Nielsen et al., 1996) and two extend to New Caledonia (Holloway, 1979). The taxon metaphaea Hampson is currently placed in Pantydia but probably incorrectly so as discussed below.

The type species has been recorded as feeding on
Dillwynia, Medicago (Leguminosae) and Exocarpos (Santalaceae) in Australia (Common, 1990). The host of P. metaspila is also in the Leguminosae (see below).
