Comments

Leptodrepana   , described by Shaw (1983) from the New World, is accepted as a valid genus by some authors (e.g. Shaw 1997; Brajkovic et al. 2010), while others have treated it as a junior synonym of Ascogaster   ( van Achterberg 1990; Yu et al. 2005). Tang and Marsh (1994) followed van Achterberg ’ s synonymy and treated the new species from China as Ascogaster   , but also suggested that a comprehensive revision of the group was needed as some species showed characters intermediate between Ascogaster   and Leptodrepana   . Shaw (1997) discussed the difficult status of Leptodrepana   , arguing for a separate genus since Ascogaster   would otherwise be paraphyletic. However, no comprehensive analysis has yet been undertaken using a combined morphological and multigene approach to resolve this question. Here we treat all relevant species as Ascogaster   , but point out that A. brevivena   sp. nov. exhibits characters intermediate between these two genera, such as having equilateral ocelli as in Leptodrepana   .

Key to Ascogaster   from the Australian arid zone

1. SR-1 not completely sclerotised, not extending to the margin of fore wing ( Figure 4e View Figure 4 ); female with 22 antennomeres; ocelli equilateral ( Figure 4c View Figure 4 )................. ................................................................................................. Ascogaster brevivena   sp. nov.

- SR-1 completely sclerotised, extending to the margin of fore wing ( Figure 5e View Figure 5 ); female with 19 antennomeres; ocelli isosceles ( Figure 5c View Figure 5 ) ......................................... 2

2. Carapace elongate with extended tip, teeth on posterior end present ( Figure 6c View Figure 6 , arrowed)................................... ................................... Ascogaster prolixogaster   sp. nov.

- Carapace oval, but not elongated, posterior end rounded without teeth ( Figure 4a View Figure 4 )......................................................................................................................................... 3
