Originally described as a subgenus of Codringtonia,[2] Neocrassa was elevated to genus level following molecular phylogenetic analyses.[4][5][3] There are several characters that distinguish Neocrassa from Codringtonia: distal part of flagellum coiled, long diverticulum of bursa copulatrix, strongly branched mucous glands, missing atrial stimulator, love dart anchor-like in cross-section, and a different course of mating.[2]
