 The galls, though bearing separate numbers, had been placed together with galls of Amphibolips gainesi, and the galls of the species are superficially similar, but the gall of D. pruniformis differs in not being perfectly round and in being colored yellowish and reddish brown. The adults are typical of the species of Disholcaspis. They agree closely with the description of D. heynei Kieffer which was described (1910, Boll. Lab. Zoo. Gen. e Agr. Portici, IV, p. 113) from the adult only. They are to be distinguished from that species by their smaller size, by being bright reddish brown in color (heynei is described as rufous with the abdomen blackish brown), by showing a broad transverse groove at the base of the scutellum (this is narrow and indistinct in heynei), by having toothed claws (heynei was described as having "crochets simples"), and by details of thoracic configuration and wing venation. D. pruniformis has a smaller second abdominal segment than most species in the genus.
