ClinidiinaRoss T. Bell
The Clinidiina is the second largest subtribe of Rhysodini. The group is nearly cosmopolitan. Although entirely absent from Africa, Clinidiina are present in Madagascar. The subtribe is richest in species in the Neotropical Region and in the Oriental Region (excluding India). In most regions, all species have vestigial hind wings, strongly modified eyes, and reduced or modified elytral striae. Winged species, capable of flight and with large, "normal" eyes and complete striation are found only in Madagascar.
A key to the genera of Clinidiina is available here.
In contrast to all other Rhysodini, the minor hairs of the antennae are confined to the ventral surface where they form a narrow band or oval or circular tuft. In a few species they are entirely absent. The apical antennal segment has an apical stylet. The median lobe of the head is short. The frontal grooves are nearly or quite complete. The elytron lacks an apical striole.
This group is apparently phylogenetically isolated by the unique arrangement of minor setae. According to Beutel (personal communication) the structure of the metathorax is more primitive than in other tribes.
