diagnosis
Diagnosis. Scales absent, postantennal organ present, ocelli 8 + 8 on pigmented eye spot, G and H normally reduced in size; only antennal segment I and rarely antennal segment II or III subdivided or III angled, secondary sexual characters present on antennae and occasionally anterior margin of head in male; tenent hair pointed, not clavate; mucro with 2 teeth, mucronal spine absent, manubrium with 2 + 2 ventral distal spines, dens without spines.
discussion
Remarks. A fuller diagnosis and figures of characters are given in Mari Mutt and Greenslade (1985). These authors did not describe or figure spines distally on the anterior face of the manubrial thickening although Fjellberg (2007) noted they were present in all European Orchesellinae. These spines have now been observed in both males and females of Australian species.
