Description
The body colour of the species varies from black (dorsal) to brown (ventral), legs may be a red-brown. To reduce the abrasion of the ventral abdomen, ventrites 3–5 are covered in a large number of setae, which is one of the distinguishing features of this species. To further identify M. aberrans from other Mecodema species there is a difference in the size of the asetose punctures along elytral striae 9 in comparison to striae 1.[2]
