Nandeva fittkaui Cranston

( Figs 29–33 )

Nandeva fittkaui Cranston, 1999: 296 .

Material examined. Paratype female in exuviae, AUSTRALIA: Clohesy R., 16°59'S 145°38'E, 7-8.ix.1997, McKie ( ANIC, Australian National Insect Collection).

It is not possible to add any measurements or many details to the description of this pharate female pupa given by Cranston (1999). The details of the wings and legs are not clear. Accordingly both the Tanytarsini type venation and the typical long spur of the front tibia may not be present in N. fittkaui .

The female genitalia ( Figs 29–33 ) differ from other Nandeva in several details. A floor apparently is absent, tergite IX has two groups each of about 8–9 setae, the ventrolateral lobe is in the same plane as the dorsomesal lobe and are covered with strong microtrichia, and the spermathecal ducts are straight. When this is added to the significant differences found both in the male and in the pupa N. fittkau seems to deserve a separate genus.
