The present study was based on collections containing members of the little studied subfamily Hexacentrinae Karny, 1925. A single genus Hexacentrus Serville, 1831 with 2 species i-e Hexacentrus unicolor Serville, 1931 and Hexacentrus pusillus Redtenbacher, 1891 were came in collection during the year 2014. Hexacentrinae may be a sister group of Conocephalinae due to reason that majority of representatives of subfamilies Hexacentrinae and Conocephalinae having significant similarities in their hind wings venation. Beside this, its predatory mode of life makes the association with other subfamilies such as Tympanophorinae, Listroscelidinae, and Saginae.
