Natural history.

The two specimens were collected from two different ant nests under stones. One with an unknown species of Lasius Fabricius, 1804 and the other with Lepisiota (cf.) Lepisiota spinisquama (Kuznetsov-Ugamsky, 1929), M. Sharaf det., 2023, collected in the evening on an open, dry area in the mountains (Fig. 6A ).

Remarks.

Commatocerus concinnus was described based on one male from United Arab Emirates, Ras al Khaimah, Wadi Shawkah, 25°6'15.30"N, 56°2'47.55"E, collected by a water-trap. The species is readily separated from its congeners by having the terminal antennomeres cylindrical, instead of distally expanded.

The generic name Commatocerus has been subjected to much instability. It was established by Raffray (1882: 1) for Commatocerus elegantulus Raffray. In the same year, Reitter (1882) synonymized it with the genus Fustiger LeConte, 1866 under the name Comatocerus [sic] ( Reitter 1882: 200). Jeannel (1949: 37) redescribed the genus and resurrected its generic status. He also pointed out that the American and Old World species of the genus Fustiger cannot be congeneric and should be placed in separate genera. Later, Jeannel (1954: 152) discussed the status of similar genera Commatocerus , Fustigerinus Wasmann, 1912 and its actual synonym Neocommatocerus Jeannel, 1949. Célis (1975: 441) confirmed the generic status of Commatocerus . Besuchet (1977: 261) again synonymized it with Fustiger and provided a key to species of India. When describing Commatocerus concinnus ( Besuchet and Cuccodoro 2011: 164), the authors discussed and supported the validity of the genus and they apparently overlooked the synonymy of Besuchet from 1977.
