Omophron aequale is a species of ground beetle in the family Carabidae. It is distributed in East Asia. ^[2]

The species is very similar to Omophron limbatum . Although the puncturation (the arrangement of punctures) on the pronotum of O. aequale is a little finer than that of O. limbatum, it is denser. ^[2] The species also has denser and coarser puncturation on the side margins of the first two sternites. ^[2]

Omophron aequale is divided into 2 subspecies: O. aequale aequale and O. aequale jacobsoni. ^[2]

O. aequale aequale has a length between 6.4 and 7.2 mm and a width between 4.2 and 4.4 mm. It is distributed in Japan and Sakhalin Island, Russia. ^[2]

O. aequale jacobsoni has a length between 6.5 and 6.9 mm and a width between 4.1 and 4.5 mm. It is distributed in China (Guandong, Guanxi, Hainan, Jiangsu, Nei Mongol, Sichuan, Shanki, Yunnan, and Zhejiang), Mongolia, North Korea, South Korea, and eastern Russia. ^[2]
