Identification

Casinaria are distinguished from related Campopleginae by combinations of characters including: propodeal structure, fore wing venation patterns, and details of the metasomal petiole. Specific identification requires examination of minute morphological features such as patterns on the mesoscutum and scutellum, flagellomere proportions, and coloration of and . The genus is morphologically diverse; some species have sculpture on and with densely punctate mesoscutum, while others show smoother .
