Aleeta n.gen. and Tryella n.gen.

Within the Australian clade the strong differentiation between curvicosta and all other Australian species ( Figs. 15–17) supports the generic separation of curvicosta . This generic separation is further supported by six autapomorphies: male genitalia with beak-like uncal lobes, partially bifurcate upper pygofer lobes, a pair of sublateral flanges near the distal end of the theca and laterally flattened conjunctival claws, plus male opercula that extend clearly beyond the lateral margins of the abdomen. It is proposed here that curvicosta be placed in the monotypic genus Aleeta n.gen. The sister clade of curvicosta , to be proposed here as the genus Tryella n.gen., is well supported by four non-homoplasious synapomorphies (11.2, 16.1, 17.2 and 24.2) and one homoplasious forward change (18.1). The generic separation of Aleeta and Tryella is also supported by electrophoretic analyses which revealed a great genetic distance between Aleeta curvicosta and five Tryella species that were available for study (Serkowski & Moulds, unpub. data).
