Cardiocondyla longiceps Seifert, 2003

Cardiocondyla longiceps Seifert, 2003 . - Ann. Naturhist. Mus. Wien 104 B: 259. (Yemen: Socotra Island).

Specimens examined: Yemen, Socotra Island: 1 ♀ (holotype), 3 ♀ ♀ (paratypes), Hadibo, 14.IV.1993, A. van Harten, SMNG .

Remarks: This species has been just recently described (Seifert 2003) from winged gynes originating both from Socotra Island and the Yemen mainland ( Ta’izz). The workers are as yet unknown. As a member of the Cardiocondyla shuckardi-group, the new species has the propodeal spines much shorter than in C. emeryi, a character true also for workers in this species group. On the known measurements of gynes and workers in related species, Seifert (2003) predicted morphometric data for C. longiceps workers, on the basis of which we include the species in the key. The species of the C. shuckardi-group inhabit arid parts of Madagascar, Africa, southern Arabia and the Middle East. Cardiocondyla longiceps may be predicted to occur around the Horn of Africa also.
