Laimosemion gili is described from the Rio Preto drainage, Rio Negro basin, Amazonas state, Brazil. The new species was found in a small creek called Garukana, within a tropical rainforest in the vicinity of Campinas do Rio Preto. This miniature species is considered to be a member of the subgenus Owiyeye, which is diagnosed by a unique frontal squamation. Laimosemion gili can be distinguished from all other species of the genus by the unique colour pattern, having a metallic blue stripe starting midbody which reaches the origin of the caudal fin. The new species is apparently related to L. romeri, sharing with this latter species a broad black stripe on flanks in males, but is easily distinguished by some other morphological characters.
