Aemene pseudonigra sp. n.
8-9mm. This species resembles Siccia nigra
van Eecke (Sumatra) in facies, including a paler grey tuft to the apex of
the female abdomen. The characteristic fasciation is largely obscured by the
general dark grey colour of the forewing, and there is a narrow marginal band of
even darker grey. Also the innermost component of the postmedial runs just basal
to the discal dot. All fasciae are more broadly represented at the costa. There
is a characteristic dull, pale, yellow-brown scent pencil along the dorsum of
the underside of the male forewing. The male hindwing is paler grey than that of
the female, and the male antennae are ciliate. S.
nigra has fewer, more obscure fasciae with more irregular boundaries to
them. The male genitalia of pseudonigra have
the uncus distinctly domed. There is a brush of setae between the valve bases
not seen in congeners, but reminiscent of the structure seen in the Garudinia group of genera. The valve apex is acutely bifid as in marginipuncta,
and the lack of a saccular process is also as in that species. The aedeagus
vesica has a rugose knob and a thorn-like spine amid more general scobination.
The female genitalia have the lateral pockets weak on the seventh segment, but
there are long, shallow ones laterally on the sixth.
