One of three very similar species. This species is larger than Macrophya ribis and the head around the frons and temples is almost impunctate (in ribis, the head has dense, coarse punctures in these areas). The white on albicincta extends to the edge of the pronotum and the scutellum and also sometimes the first tergite (these are all black in ribis).
Macrophya alboannulata specimens have previously been identified as albicincta but were recognised by Liston and added to the checklist. The two species can be separated by the colouring on the hind trochanters. In albicincta the hind trochanters are predominantly black, whereas in alboannulata the hind trochanters are significantly marked with white.
