Campanithrips gen. n.

Type species. Campanithrips kyakhei gen. et sp. n.

Diagnosis. Head with eyes protruding over the base of antennae. Antennae nine-segmented with the distal segments fully distinct from each other; segment III distally with broad sense cone (sensoria not visible on IV). Setae on head and pronotum not assessable (at least some longer posteromarginal or posteroangular setae present). Mouth cone short and rounded. Fore wings with softly pointed tips; hind and front margin with straight wing fringes; costal setae long, about as long as wing width in the middle; both longitudinal veins complete but with a slightly larger gap between the penultimate and the distal seta; with two (visible) cross veins. Fore wing surface with microtrichia. Fore femora slender; fore tarsi with hamus.

Based on the above-mentioned character states of the fore wings and the broad sense cones Campanithrips gen. n. is attributed to Stenurothripidae (see Bhatti 2006). At present, this family comprises ten fossil and three extant genera ( Mound & Hastenpflug-Vesmanis 2021). Campanithrips gen. n. differs from all fossil genera by the straight fringes on the hind margin of the fore wings ( Schliephake 1990, p. 180; Peñalver & Nel 2010; Tong et al. 2019; Guo et al. 2024) and is thus more similar to extant forms. Compared with extant Holarthrothrips Bagnall and Oligothrips Moulton the new genus has less setae on the wing veins, but these are much longer and stronger than in Heratythrips Mound & Marullo.

Etymology. The name Campanithrips gen. n. refers to the Campanian origin of amber and is combined with -thrips, the usual term for a genus within Thysanoptera .
