Distribution This is the first record from Saudi Arabia . This species was described from South America being a typical representative of New World Condylostylus , having no relatives in the Afrotropical fauna. It was only recently found in the Southern part of the Arabian Peninsula, i.e. in the United Arab Emirates ( Naglis and Bickel 2017 ), and the authors suggested that this occurrence was most probably the result of accidental human introduction. C. longicornis is known from Australasian ( French Polynesia and Hawaiian Is.), Nearctic and Neotropical regions ( Grichanov 2018 ). Dr. Deeming believes that this species could develop in shipments of grain that are infested with grain beetles and other insects, as both larvae and adults are predacious, and there would be adequate food for them, especially if there was a fungal infestation of any kind (J.C. Deeming; pers. comm. 2019).
