Subgenus Leuconephropolia subgen. n.

Type-species.

Polia albirena Draudt, 1950, by monotypy.

Diagnosis.

This isolated species is strikingly different from all other Polia species by its slenderer body, more elongate triangular and somewhat acute forewings, longer pectinated and relatively long antennae of males, by dark greyish-brown colouration of thorax and fore wings with some violaceous shine.

The male genitalia also differ conspicuously from those of all other known Polia species, the diagnostic features are as follows: the saccular processes are symmetrical, relatively short and densely covered by a “bush” of strong setae terminally, and the vesica is completely helicoid and recurved, bearing a large number of thin, spiniform cornuti and a small terminal diverticulum.

The female genitalia are also very specific: the sclerotisation of the antrum is weak, connected to ductus bursae with a slightly constricted membranous section ( “neck”), the ductus bursae is flattened and more sclerotised, the corpus bursae is saccate, lacking signa, while the appendix bursae is broad and retroflexed.

Etymology.

The name refers to the light reniform stigma of the type-species.
