This study was carried out in Khuzestan province, located in the southwest of Iran in 2016. The genus Ceratobracon Telenga, 1936 (Hymenotera: Braconidae) is recorded for the first time from Iran represented by a single species, Ceratobracon stschegolevi (Telenga, 1933). Geographical distribution, diagnostic characters of the newly recorded species and a key to the known species of Ceratobracon are also provided. Key words: Khuzestan, Iran, Ceratobracon, new record, Malaise trap. Introduction Braconinae Nees, 1811 is one of the largest and cosmopolitan of braconid subfamilies, with 189 genera and 3052 described species, mostly spread in the Old World tropics, especially Africa and South-East Asia (Shenefelt 1978, Quicke 1987, 2015, Yu et al. 2016). Bracon Fabricius, 1804, with over four- teen subgenera, is the most diverse genus in the subfamily of Braconinae with over 1000 described species worldwide (Yu et al. 2016). Ceratobracon was established by Telenga (1936) as one of the subgenera of Bracon Fabricius, 1804 but later raised as separate genus (Tobias 1971). At the outset, this ge- nus included three species which lately two of them includ- ing Ceratobracon orbicularis Niezabitowski, 1910 and C. apri- cus Schmiedeknecht, 1897 are considered as synonyms of Bracon (Bracon) nigratus (Wesmael, 1838) and Bracon (Luco- bracon) apricus Schmiedeknecht, 1897, respectively. Another species was described from Turkey, Ceratobracon adaniensis Beyarslan, 1987. Based on known host association, even though there are no host records for the majority of braconine genera, most of the species are known as ectoparasitoids of the insect larvae be- longing to Coleoptera, Lepidoptera and Diptera. It should be noted that van Achterberg, (1984) reared some members of the Philomacroploea Cameron, 1905 and Aspidobracon van Achterberg, 1984 from pupae of lepidopteran families Nym- Figure 1.
