Head with ocellar setae III small, shorter than length of an ocellus, arising between anterior margins of posterior ocelli. Pronotum with weak sculpture lines, all setae minute.

Male smaller than female, tergite I with pair of longitudinal ridges.

Related and similar species

Twelve species are currently described in the genus Cranothrips, 11 from Australia and one from South Africa (Pereyra & Mound, 2009). C. bellisi is the smallest and palest of these species and, unlike typical species of Melanthripidae, bears no long setae on the head and pronotum.
