The wing length 6-8·25 mm. Dark ground colour with steeply inclined hooked markings (the inner limb is strongly oblique). Very similar to A. contracta, but transfuga has the lateral margins of tergite 2 less concave than in contracta. There are also differences in the grey dusting of the sternites (sternites 2 and 3 are completely grey dusted in the male of transfuga). [3]
