{Lepisiota gracilicornis}The photomontage is of specimens collected in Sudan, at Port Sudan by Awatif Omer. 


{Lepisiota gracilicornis}The photomontage is of specimens collected in Sudan, at Afad (South Ad Damazin), 11°46'0"N 34°21'0"E, by Awatif Omer, 2009.


Lepisiota gracilicornisThe photomontage is of a worker from Sudan, collected by J Mathews, by pyrethrum fogging of Acacia senegal, Kordofan, El Ain, ca 12°56' N 30°35' E; 18.x.2000, JM 040, 1 worker


{Lepisiota gracilicornis}The photomontage is of a worker collected in the Sinai Desert, Egypt, St Katherine protectorate around the town of St Katherine, in mountains above 1500m, in early 2001, by Mike James, a research student of Francis Gilbert. Collingwood (1985) described the species as from the Middle East, Arabia, "very long appendages, long thin alitrunk and brilliantly shining integument", with antennal scapes twice as long as head width. These Sinai specimens match Forel's original description and the scapes surpass the occiput by 2/3 their own length, SI (i.e SL/HW) = 240. It seems from this that the separation in Collingwood & Agosti (1996) is wrong and, hence, their definition of a separate species, Lepisiota riyadha is questionable. What seems to be true is that the species shows variable worker size within the same colony.


{Lepisiota gracilicornis}The photomontage is of a worker from Senegal, Katané;  collector B Ndiaye (Katané X 2010 T4RM20).


{Lepisiota gracilicornis} The photomontage is of specimens from Yemen, Socotra Island,  Al Haghier Mts., wadi Madar, 1180-1230 m, 12°33.2'N 54°00.4'E, 12-14.xi.2010, collected by J. Batelka (ex P. Hlavac). Previously identified by me as Lepisiota spinisquama.

Noted by Collingwood & Agosti (1996: 369) as having exceptionally long curved spines and "is apparently common on the island of Socotra". See also {original description}. I strongly suspect their identification was incorrect, as L. spinisqama does not have very long spines on the propodeum or petiole.
