Diplogeomyza diaphora can be distinguished from most similar looking species by the addition of four smaller scutellar marginal bristles along side the usual four large bristles. From D. tridens (not found in Tasmania) it differs by having the hind femur noticeably darkened apically, instead of being darkened only at the extreme apex for that species. The wings have the anterior cross-vein, the posterior cross-vein, and the apices of R2+3, R4+5, and M faintly marked brown. Bodylength around 5mm.
