Diagnostic Notes
Body length 1.8 to 2.8 mm. Elytra are short, relatively broad and together are somewhat square in shape. The elytra of the female are strongly marked with a pattern of white and pale grey setae on a dark (almost black) background. The male has rather uniform light grey-brown pubescence (sometimes mottled with darker brown) over a dark-grey cuticle. On the apex of the tibia of each hind leg there are two movable spurs, called calcaria; these are reddish in colour and equal in length. There are no teeth on the hind femur. The tenth stria of each elytron is about half as long as the elytron. The front coxae are contiguous and not separated from each other by a ventral process. (CABI 2004)
