Nesolasius Wheeler, 1935 Pseudolasius is a genus of ants in the subfamily Formicinae.

[2] The genus is known from southern Asia (from India to China) to northern Australia, where it appears to be restricted to tropical areas.

The body is often covered in dense fine hair (pubescence).

The eyes are often poorly developed and usually positioned below the middle of the head.

The workers exhibit strong polymorphism, with a major caste that has a notched hind margin of the head.
