Homotropus riedeli Johansson, 2020 ( Fig. 1A–I)

Material examined. 1♀, Iran, West Azarbaijan province, Piranshahr , 36°34'32"N, 45°12'43"E, 1399 m, 15- VII-2020, leg.: S. Karimi.

Diagnosis. Female. This species was originally described by Johansson (2020) from Sweden. Our specimen is very similar to the holotype. Face entirely coriaceous and matt ( Fig. 1B). Antenna with 20 flagellomeres ( Fig. 1D). Mesopleuron centrally anteriorly with shallow punctures ( Fig. 1H). The interstices about equal to the diameter of punctures. In lower part, punctures become indistinct against coriaceous background. In upper part, punctures partly fade to irregular, almost rugose sculpture. The area around mesopleural furrow polished without punctures. Metapleuron coriaceous, shining. Mesoscutum shining with weak microsculpture between punctures, centrally becoming more strongly coriaceous. Scutellum weakly coriaceous with distinct punctures, interstices between punctures slightly larger than diameter of punctures ( Fig. 1E). Propodeum strongly irregularly rugose, with area petiolaris and indicated area superomedia delimited by strong, irregular carinae ( Fig. 1E–F). Indicated area superomedia with surface covered with irregular transverse carinae. Coxae coriaceous, matt. Fore wing with areolet closed and vein 3rs-m pigmented ( Fig. 1G). Metasoma laterally compressed from 4 th tergite. T I strongly longitudinally striate. Second tergite strongly coriaceous with weak striation basally. T III polished with weak microsculpture, in basal half coriaceous and matt. T IV–VII polished with weak microsculpture ( Fig. 1I). Spiracle of T II above lateral fold and on T III on lateral fold .

Coloration. Body and head black. Antennae reddish brown. Scapus brown, fading to brownish yellow ventrally. Clypeus, mandibles except mandibular teeth, palpi and large central face patch yellow. Face below antennal sockets dark reddish brown. Lower part of mesopleuron, metapleuron and a large spot on propodeum laterally orange. Scutellum orange. Large shoulder mark, subtegular ridge, tegulae, hind margin of mesopleuron and large spot at the hind corner of pronotum yellow. Legs orange. Fore and mid coxae yellow, orange basally. Trochanters and trochantelli on fore and mid leg yellow. Hind trochanter and trochantelli with large yellow spot. Hind legs apart from trochanter and trochantelli, entirely orange. Metasoma orange. T I centrally black with lateral and apical margins widely orange. Terga VII, and VIII black ( Johansson, 2020).

Distribution. Sweden ( Johansson, 2020). It is a new record for Iran and Asia.

Comment. The holotype of H. riedeli was collected by Malaise traps from 7th July to 14th September in Sweden which corresponds to the date collected in Iran.
