Remarks. The maculicornis group is in need of revision, as sex associations remain unclear and several synonyms are expected. In this work, we consider Chrysis exigua as a valid species. It was previously considered as a subspecies of C. distincta Mocsáry, 1889 by Linsenmaier (1968) and later synonymised with that species by Kimsey & Bohart (1991). It was not mentioned by Semenov-Tian-Shanskij & Nikol’skaya (1954), who likely include it under C. distincta . The collection at ZISP currently houses dozens of these specimens under the name of C. maculicornis Klug, 1845 identified as such by Semenov-Tian-Shanskij. Chrysis exigua is characterised by green male and corse punctation; it is widespread in Central Asia and C. quettaensis Nurse, 1903 should be its synonym.

Distribution. Armenia, Iran, Uzbekistan ( Linsenmaier 1968; Rosa et al. 2024).
