New record for Oman.  Natural history. The two specimens were collected from two different ant nests under stones. One with an unknown species of  LasiusFabricius, 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).   Figure 5.Type locality of  Corynotopsis omanicussp. nov.   Figure 6. AOman, Ad Dakhilyiah Gov., near Subayb wadi, locality with the occurrence of  Commatocerus concinnus Bdistribution map of all Clavigeritaespecies known from the Arabian Peninsula.  Remarks.   Commatocerus concinnuswas 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  Commatocerushas been subjected to much instability. It was established by Raffray (1882: 1) for  Commatocerus elegantulusRaffray. In the same year, Reitter (1882)synonymized it with the genus  FustigerLeConte, 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  Fustigercannot be congeneric and should be placed in separate genera. Later, Jeannel (1954: 152) discussed the status of similar genera  Commatocerus,  FustigerinusWasmann, 1912 and its actual synonym  NeocommatocerusJeannel, 1949.  Celis(1975: 441) confirmed the generic status of  Commatocerus. Besuchet (1977: 261) again synonymized it with  Fustigerand 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.  Species included.   Commatocerus concinnusBesuchet & Cuccodoro, 2011,  C. elegantulusRaffray, 1882,  C. leleupiJeannel, 1953 and  C. turkmenicusKryzhanovski, 1957. 2019-03-29 Lgt.
