Diplogeomyza wirthi and D. conformis are identical species that can only be reliably determined from the male genitalia characters. They are distinguished from all other similar looking species by having only four large marginal scutellar bristles (see D. diaphora for alternative), and the presence of a distinct spot at the apex of only wing vein R2+3 in addition to the marks on the anterior and posterior cross-veins. Bodylengths range from 2.1 to 5.0mm.
