  Type species:

   Neodialineura striatithorax Mann, 1928 by original designation.

Introduction

Neodialineura appears to be closely related to Manestella Metz. Neodialineura is distributed throughout all Australian states. Some species show considerable sexual dimorphism in vestiture and colouration.

Diagnosis

Velutum patches lacking on the fore and hind femora, wing cell m3 open, subapical anteroventral macrosetae on hind femur absent, aedeagus with apodemes of parameral sheath reduced, gonocoxites lacking ventromedial velutum patch and hypandrium absent or barely evident. The posteromedial region of abdominal tergite 2 of both sexes of Neodialineura is adorned with a patch of modified setae. This patch of modified setae is present in other genera of Australian Therevidae but usually only present in the female and rarely found in all species of any genus (Winterton et al. 2001).
Antennae positioned on middle to lower part of head; antennal length variable, usually shorter than head, rarely equal length; flagellum acutely turbinate; scape short and cylindrical, or rarely slightly elongate and bulbous; antennal vestiture frequently as sparsely distributed, strong setae; frons flat or slightly rounded, rarely greatly swollen with glabrous bilobed antennal callus; male frons much narrower than female; eyes usually contiguous, frons at narrowest point rarely wider than anterior ocellus; male occiput concave, one row (rarely more) of postocular setae in male immediately laterad of ocellar tubercle; parafacial setae usually absent; prosternal pile absent in medial furrow; pleuron with grey pubescence; postspiracular pile absent; scutum sometimes with stripes and tessellate patterning, or setal bases darkened against a lighter background colouration; wing hyaline or fumose, often with dark mottling; cell m3 open; vein M3 rarely incomplete; mid coxa without setae on posterior surface (except N. atmis); femora with uniform short setae, not appressed; fore and hind femora without velutum patches; hind femur without subapical anteroventral macrosetae; abdomen yellow with dark markings medially, sometimes overlain with silver velutum in male; terminalia sparsely covered with relatively few elongate setae; medial atrium absent; hypandrium reduced or absent; aedeagus simple; ventral apodeme forked widely; lateral ejaculatory apodeme small; articulated inner gonocoxal process present; anterior process of female tergite 8 broad; A1 and A2 acanthophorite spines present; three spermathecae; spermathecal sac present; spermathecal ducts joined to spermathecal duct (Winterton 2009).
