Diagnostic notes.

Phaulotypus insularis is a small brown, sometimes greenish species. The female pronotum is not protruding posteriorly. The median carina on the male femur is armed with large spines. The male pronotum has a strongly sinuous and humped median carina (Figs 107 , 108 ). The ventral carina of the hind femur is smooth in both sexes.

Taxonomic notes.

Descamps (1970) synonymised Clerithes nanus Popov, 1957 with Phaulotypus insularis (Burr, 1899) . The holotype of the former appeared to be the male of P. insularis .

Distribution and occurrence.

Phaulotypus insularis is a widespread and common endemic to Socotra (Fig. 109 ). It can be found wherever there are shrubs.

Habitat and biology.

Like all species in the genus, P. insularis is a phytophilous species found in various bushes like Jatropha unicostata Balf. f. , but also on rocks or the ground. It occurs from 10–1100 m a. s. l. and in all seasons. Nymphs were recorded in April.
