 Differential diagnosis (for more details see the key below). Socotralia reitteri sp. nov. differs from similar species S. montana sp. nov., S. vybirali sp. nov. and S. brunnea mainly in having antennomere 11 distinctly longer than antennomere 3, while S. montana sp. nov., S. vybirali sp. nov. and S. brunnea have antennomere 11 shorter than antennomere 3. S. reitteri sp. nov. differs from the similar species S. intermedia sp. nov. mainly in having space between eyes broader than length of antennomere 2, while S. intermedia sp. nov. has space between eyes distinctly shorter than length of antennomere 2. S. reitteri sp. nov. differs from the similar species S. major in having antennomere 3–10 distinctly serrate, while S. major has antennomeres 3–10 narrower. S. reitteri sp. nov. differs from the similar species S. minor in having sides of pronotum conically narrowing, while S. minor has rounded sides of pronotum.   
 Etymology. Named in honour of Edmund Reitter (1845–1920), world famous expert in Coleoptera.   
 Collecting circumstances. Members of this species were collected only at night when they were attracted to light. They were not found during the day on herb or shrub vegetation.   
 Distribution. Yemen: Socotra Island.
