Antennae 9-segmented, segment I with short apical process; sensoria on III–IV incomplete dorsally, with weak internal markings; IX slightly longer than VIII. 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. Mesonotum covered with microtrichia, setae minute. Metanotum with microtrichia on concentric lines at anterior. Fore wing setae shorter than width of veins. Fore tibial apex with two stout ventro-lateral setae. Abdominal tergites I–VII with weak sculpture lines medially; tergite VIII median setae about 0.5 as long as tergite; dorsal setae on IX–X not elongate. Sternites with numerous small discal setae.

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.
