Currently 14 species are placed in the genus Franklinothrips, all from tropical and subtropical countries, although more undescribed species are known from Southeast Asia (Mound & Reynaud, 2005). Within this genus, F. bassetti appears to be the least well-developed ant-mimic. The base of the abdomen is not constricted to form a waist, and the forewings are uniformly dusky, not banded.
