''Acromis'' is a genus of beetles belonging to the family Chrysomelidae. The three species of this genus are found in Southern America. These species exhibit subsociality, where the females lay clusters of eggs that she guards until they hatch, the larvae mature, pupate, and young adults disperse.Chaboo, C.S. 2001.

Acromis Spinifex
''Acromis spinifex'' is a species of tortoise beetle from South America. The males have enlarged elytra which are probably used in male–male combat, while females are among the few tortoise beetles to show Parental investment, maternal care of their offspring. Distribution ''Acromis spinifex'' is found across South America, from Trinidad and Tobago and Venezuela in the north to Peru, northern Argentina and Paraguay in the south. Description As with other species in the genus ''Acromis'', ''A. spinifex'' shows conspicuous sexual dimorphism. The elytron, elytra of males extend sideways and forwards to form flattened plates. Other species in the genus have been studied more closely, and they have been observed to engage in male–male combat, in which the flattened parts of the elytra are often pierced; such holes are frequently found in zoological specimen, museum specimens of ''Acromis''. Males are long and wide, while females are slightly smaller, long and wide. Ecology a ...
