Glochinomyia Kertész, 1916

Glochinomyia Kertész, 1916: 140 . Type species: Glochinomyia albiseta Kertész, 1916 (by original designation).

Diagnosis and taxonomic remarks. The genus Glochinomyia may be characterised by the following unique combination of characters: (1) antennal flagellum disc-shaped with terminal arista, (2) male eyes touching on frons, (3) scutellum with 4 spines, lateral spines shorter than medial spines, (4) vein R2+3 arising before or at cross vein R- M, (5) R4 present, (6) wing membrane with dark pattern, (7) abdomen longer than broad (1.5:1.0). None of these characters is apomorphic. Characters of the male terminalia cannot be comparatively evaluated because they are not known in G. a l b i s e t a. Kertész (1916) compared his genus with the sympatric genus Lophoteles Loew , which has a similar body shape and virtually identical wing venation. However, it differs conspicuously by having a long and densely haired antennal arista and absence of 4 scutellar spines. Both these characters are typical also for Salduba Walker and Saldubella Kertész , which both display an elongate oval basal part of the flagellum. All genera of the Papuan Pachygastrinae with 4 scutellar spines may be distinguished using the following identification key. All other Papuan genera of Pachygastrinae possess a scutellum without spines, with small marginal cornicles, a single apical spine, 2 or 6 distal spines.
