Coenochilus

There are 80 species in this myrmecophilous genus of Scarabaeidae (Cremastocheilini). Some species are known to be termitophilus. Some Cremastocheilini to which this and other genera belong (e.g. Anatonochilus Péringuey, 1907, Cymophorus Kirby, 1827, Plagiochilus Wasmann, 1900, Trogodes Westwood in Boheman, 1857, Spilophorus Westwood in Schaum, 1848) are a group of Cetoniinae that are reported to be myrmecophilous or termitophilous (e.g. Schein 1954a) and, as adults, with some exceptions, are mainly active at night (Holm & Perissinotto 2010). Some species are also predators of ant larvae (e.g. see Ghorpade 1975; Mynhardt & Wenzel 2010). The genus Coenochilus is the most speciose with about 100 species distributed throughout the Afrotropical, Oriental and Palaearctic Regions (Krajcik 2008b). Schein (1954a) revised the 41 African species known by that time and defined seven groups within the genus. There are about 48 species recognized for the former Region (Schoolmeesters 2018), eight of them previously recorded for Angola (Schein 1954a; Ferreira 1965). We give two new species records for this country.
