Acrossus igai is a species of beetle of the family Scarabaeidae. It is found in Japan.

Description

Adults reach a length of about 6.5–7.5 mm (0.26–0.30 in). They are similar to Acrossus japonicus, but the rows of punctures are distinct right up to the apex and the elytra have a fairly clear microsculpture, making them less shiny.
