Material examined. IRAN - West Azarbaijan province: 3 ♀♀, 2 ♂♂ (HMIM): Khoy; 38°42'30.648" N, 44°54'1.540" E; Elev. 1414 m a.s.l.; 19.viii.2022; reared on Anarsia eleagnella Kuznetsov, 1957 ( Lepidoptera , Gelechiidae ) emerged from Russian olive ( Elaeagnus angustifolia L.); M. jafarlu leg. 3 ♀♀ (HMIM): Khoy; 38°35'38.805" N, 44°48'32.172" E; Elev. 1293 m a.s.l.; 03.ix.2022; same data as for preceding; 2 ♀♀, 1 ♂ (HMIM): Urmia; 37°40'5.358" N, 45°0'43.846" E; Elev. 1340 m a.s.l.; 08.xi.2022; same data as for preceding; 18 ♀♀, 10 ♂♂ (HMIM): Urmia; 37°33'13.648" N, 45°8'22.388" E; Elev. 1305 m a.s.l.; 16.x.2022; same data as for preceding; M. Hassan-Pashai-Mehr leg.

Diagnosis Female. Head and mesosoma blackish green with metallic luster ( Figs. 2A, 3A–D, F); antenna bronzy ( Fig. 2); legs bronzy to amber; basal parts of coxae concolourous with mesosoma ( Fig. 2A, 3A); metasoma fuscous to bronzy ( Fig. 2A, 3G). Antenna of the female with a lower placoid sensillae than that of Hyssopus nigritulus (Zetterstedt, 1838) ( Fig. 2A, 2B). Thorax flat dorsally ( Fig. 2A, 3A); mesoscutum with fine reticulation ( Fig. 3C); mesoscutellum smooth and shiny, sometimes alutaceous anteriorly ( Figs 3C, 3F). Fore wing with marginal vein 3× as long as stigmal vein; submarginal vein with 7 setae dorsally; speculum small ( Fig. 2A, 3E). Gaster oval and longer than the length of the thorax and propodeum together ( Fig. 2A, 3G).

Male. Similar to female except enlarged and more globular head; antennal scape inflated with fewer placoid sensillae; gaster squatter than that of female ( Figs 2C, 2D).

Primary hosts. Based on our findings, H. geniculatus is a primary ectoparasitoid of A. eleagnella larvae. Generally, H. geniculatus is an ectoparasitoid of lepidopterous larvae ( Bouček & Askew, 1968; Trjapitzin, 1978; Ermolaev et al., 2019), and additionally, two coleopterous species from Scolytidae and one dipterous species from Cecidomyiidae have been reported as its primary hosts ( Bouček & Askew, 1968). Its lepidopterous hosts are Gelechiidae , Gracillariidae , Pyralidae , and Tortricidae ( Bouček & Askew, 1968; Bouček, 1977; Trjapitzin, 1978; Yefremova et al., 2007).

Distribution. Afrotropical: Yemen (Yefremova, 2007); Palaearctic: Europe, Israel, Japan, Korea, Peoples' Republic of China, Russia, Tajikistan, Turkey, Turkmenistan ( Noyes, 2019), Iran ( Yefremova et al., 2007; Ebrahimi et al., 2009).
