Remarks: Both the original description and information by Pisarski (1967) demonstrate that this species is distinct from L. semenovi  (Ruzsky, 1905), so the synonymy of the two species recently proposed by Dlussky et al. (1990) cannot be accepted. The occurrence of L. spinisquama  on Socotra, where it appears to be one of the commonest ants, is something of a riddle. The species is distributed in central Asia, and there are records from coastal southern Arabia (Collingwood 1985, Collingwood & Agosti 1996), but otherwise introductions have not been reported. This shiny black ant is characterised by spinal ornamentation on both the propodeum and the petiole. Nests may include several queens and many hundreds of workers. These ants are general scavengers and will attack other insects. In Socotri, "nimihil haher" (black ant) will usually refer to this species.
