Identification of Carcelia amplexa requires examination of morphological characters, particularly features of the male terminalia and chaetotaxy (bristle arrangement). The Carcelia is distinguished from related tachinid genera by characteristics of the abdominal sternites and the structure of the male genitalia. Specific distinguishing features for C. amplexa relative to such as C. laxifrons or C. excisa include subtle differences in the shape of the and surstyli, best resolved through microscopic examination and comparison with .
