Hormiini is represented by five species in two genera, Avga Nixon, 1940, with a single new species, A. sinaitica Edmardash & Gadallah; and Hormius Nees, 1819 (4 species), H. moniliatus (Nees, 1811), H. propodealis (Belokobylskij, 1989), H. sculpturatus Tobias, 1967, and H. similis Szépligeti, 1896. One species of Macrocentrinae, Macrocentrus collaris (Spinola, 1808) is also reported here. The specimens were collected from different localities of Egypt. Key words: Avga, Hormius, Macrocentrus, localities, new species, new records, Egypt Introduction Hormiini Förster, 1863 is a relatively small, cosmopolitan tribe currently comprising 72 species in four genera (Avga Nixon, 1940; Hormisca Telenga, 1941; Hormius Nees, 1819; and Taiwanhormius Belokobylskij, 1988) (Yu et al. 2016). Most species belong to the genus Hormius (92% of the total number of species). Hormiini are closely related to Doryctinae, Rhysssalinae, and Rogadinae sensu stricto, but differs from them in having CU1a interstitial; second and third metasomal tergites largely membranous, desclerotized (except in very few cases) (van Achterberg 1995). The genus Avga is commonly included in the tribe Hormiini under the subfamily Rogadinae sensu lato especially for non-Australian species (van Achterberg, pers. comm.; Chen & van Achterberg 2019). They are gregarious or solitary ectoparasitoids of lepidopteran larvae (Yu et al. 2016; Chen & van Achterberg 2019). Hormiines are diagnosed by the following combination of characters: female antennae slender, with larger, but relatively short, pedicellus in relation to scape; prepectal carina complete, well-developed, but if weakly developed, then fore wing devoid of vein r-m (van Achterberg 1995). Macrocentrinae Förster, 1863 is a cosmopolitan, medium-sized subfamily, with 237 species in eight genera (Yu et al. 2016), with Macrocentrus Curtis, 1833 is the most diverse and large genus in the Old World, with 191 described species (81% of the total number of species) (Akhtar et al. 2014; Yu et al. 2016). Wharton (1993) placed Macrocentrinae among the helconoid complex, a fact that is strongly supported by a recent phylogenetic study car- ried out by Sharanowski et al. (2011), based on molecular data. Macrocentrinae are koinobiont solitary or gregarious endoparasitoids of both macro- and microlepidopteran larvae (Sharanowski et al. 2014; Chen & van Achterberg 2019), with a large number of species have been reported from multiple hosts (Yu et al. 2016). The Palaearctic species of Macrocentrinae have been revised by van Achter- berg (1993a). From the most important diagnostic characters, macrocentrines have a subapical comb of short pegs on all trochantelli anteriorly (exceptionally on hind trochantellus only); mesoscutal median lobe somewhat bulging or Accepted by J.
