Differential diagnosis (for more details see the key below). Socotralia montana sp. nov. differs from the similar species S. vybirali sp. nov. mainly in having antennomeres 3–10 relatively narrow while in S. vybirali sp. nov. antennomeres 3–10 are slightly serrate and distinctly broadest at apex. From S. intermedia sp. nov., S. reitteri sp. nov., S. major and S. minor it differs mainly in having antennomere 11 distinctly shorter than antennomere 3, while in the previous species the antennomere 11 is distinctly longer than antennomere 3. Socotralia montana sp. nov. can be distinguished from S. brunnea by its narrow, elongate body and parallel pronotum, while in S. brunnea the body is slightly oval and pronotum more transverse and rounded.
Etymology. Latin adjective montanus, - a, - um (= montane), expressing the species affinity to high (mountain) altitudes.
Collection circumstances. The adults were collected at night by shaking off the shrub vegetation. They were also attracted to light.
Distribution. Yemen: Socotra Island.
