• Vomerina Winterton, S.L. 2007. New species of Acraspisoides Hill & Winterton and Bonjeana Irwin & Lyneborg (Diptera: Therevidae: Agapophytinae), with the description of a genus. Zootaxa 1438: 1-25 [22].

  Type species:

   Vomerina humbug Winterton, 2007 by original designation.

Introduction

Vomerina is likely the sister taxon to Bonjeania based on external body shape. The male genitalia of this species are quite different in shape to any other therevid by lacking a medial atrium and inner gonocoxal process, the ventral lobe shape and having a well-sclerotised dorsal apodeme of the parameral sheath. The large, plowshare-shaped ventral lobes are distinctive and observable in undissected specimens. Dramatic reduction of inner gonocoxal processes is found in only one other Australian genus, Actenomeros Winterton & Irwin (Winterton et al. 1999b), where the inner gonocoxal process is reduced but not completely absent as is found in this species. Vomerina is known only from a series of males from Tinderry Nature Reserve, New South Wales (Winterton 2007c).
