Abstract
An addendum to the recent checklist of the Chrysididae from Mongolia is given. Examination of old museum material and recently collected specimens has led to the discovery of eight new records for the country and eleven new species for science. Eight species are newly recorded from Mongolia: Chrysisinclinata Linsenmaier, 1959, C.martinella du Buysson, 1900, C.speciosa Radoszkowski, 1877, Euchroeuspurpuratus (Fabricius, 1787), Holopygalucida (Lepeletier, 1806), H.similis Mocsáry, 1889, Hedychridiumfemoratum (Dahlbom, 1854) and H.leleji Rosa, 2017. Two species, Hedychridiumcupreum (Dahlbom, 1845) and H.propodeale Rosa, 2017 are excluded from the checklist of Mongolian Chrysididae: the former is described here as H.erythrosomasp. nov., the latter is identified as H.leleji Rosa, 2017. The hitherto unknown male of Chrysismocsaryi Radoszkowski, 1889 is described and illustrated. Eleven new species are described: Chrysisstrakaisp. nov., C.woodisp. nov., Hedychridiumerythrosomasp. nov., H.frontalesp. nov., H.jacobsisp. nov., H.splendenssp. nov., H.striatumsp. nov., H.varvaraesp. nov., H.weiisp. nov., Holopygatyrnerisp. nov., and Philoctetesborekisp. nov. Keys to males and females of all known Mongolian species of Hedychridium Abeille de Perrin, 1878 are provided. The Mongolian cuckoo wasp fauna now comprises 107 species in 18 genera and two subfamilies.
Highlights
Rosa et al (2020) recently provided the first checklist of the Mongolian cuckoo wasps, including 90 species in 18 genera
We describe Hedychridium spendens sp. nov. in the H. femoratum species group and it is related to H. jacobsi by its general habitus, F1 and yellowish legs
We tentatively describe Hedychridium striatum sp. nov. in the Hedychridium ardens species group; for some diagnostic characters, such as genital capsule and yellowish legs, it can be confused with members of other species group (H. rhodinum and H. femoratum groups); the female shows narrow and elongate eyes as members of the H. planifrons group
Summary
Rosa et al (2020) recently provided the first checklist of the Mongolian cuckoo wasps, including 90 species in 18 genera. The checklist was based on specimens collected by Czech entomologists Kadlecová) in 2003– 2007 and on the revision of published data, to clarify the confusion given in previous literature on true Mongolian localities. Most of the published bibliographical data recorded for “Mongolia” refer to localities currently included in China (Inner Mongolia, Xinjiang, Gansu)
