Trissolcus perepelovi was identified using the key of Talamas et al. (2017) . Key characters used to identify this species are the absence of a hyperoccipital carina, metapleuron without setation, absence of episternal foveae, female antenna with five clavomeres, and a bulging anteroventral portion of the mesopleuron. Material examined. Rafsanjan , Kerman Prov. , Iran , 2019, reared from eggs of Acrosternum arabicum and Brachynema signatum , 85 females , 41 males : FSCA 00093760-00093762, 00093764, 00093773-00093774, 00093776-00093777, 00093779, 00093781-00093782, 00093785, 00093787, 00093791, 00093794-00093797, 00093799-00093804, 00093807-00093812, 00093814-00093815, 00093817, 00093819-00093820, 00093822-00093823, 00093825-00093831, 00093834-00093841, 00093843-00093844, 00093846-00093848, 00093850-00093853, 00093855-00093857, 00093859-00093860, 00094200-00094201, 00094203, 00094206, 00094208, 00094210, 00094212-00094214, 00094216-00094218, 00094220-00094226, 00094229, 00094233-00094234, 00094245, 00094250-00094253, 00094256-00094259, 00094262-00094264, 00094268, 00094270-00094272, 00094274, 00094276, 00094278-00094279, 00094282-00094283, 00094286-00094288, 00094291, 00094294-00094295, 00094299-00094300, 00094411, 00094875, 00095709-00095710 . Intraspecific variation. Among the specimens analyzed here, we found that there is more variation in the microsculpture of the frons (Figures 15-16 ) than was documented by Talamas et al. (2017) . Specimens reared from B. signatum tend to have more microsculpture than those from A. arabicum , but this is not a perfect correlation. Specimens reared from B. signatum tend to have a metasoma that is lighter in color than those reared from A. arabicum , a phenomenon that Ganjisaffar et al. (2020) reported to be host related in some Nearctic Trissolcus species. We generated two COI barcode sequences for T. perepelovi , one from a specimen reared from A. arabicum , and the other from B. signatum , which have a 99.53% sequence identity. These specimens have slight variation in the degree of microsculpture on the frons and both have a dark metasoma. This suggests that the variation described above is not entirely attributable to the host species. Comment. In this study, T. perepelovi was reared from the eggs of Acrosternum arabicum and Brachynema germari . It was previously reported by Mohammadpour et al. (2016) , as T. deserticola , to parasitize the eggs of B. germani in Kerman province. Figure 20. Trissolcus semistriatus , female (FSCA 00094876), habitus, lateral view.
