COI barcodes confirmed that this specimen belongs to A. kretschmanni sp. nov. Discussion Taxonomic placement of Aphanogmus kretschmanni Moser sp. nov. In the Palearctic, the family Ceraphronidae contains 112 species in 6 genera. Aphanogmus Thomson, 1858 is the most species-rich genus with 52 described species (Johnson & Musetti 2004; Buhl et al. 2010; Matsuo 2016), whilst four other genera comprise no more than six species. Aphanogmus is characterised mainly by a laterally compressed mesosoma, which is taller than broad (Figs 1, 3A–D) as well as trapezoidal flagellar segments on the male antennae with sensillae at least as long as the width of the flagellar segments. Currently, Aphanogmus is separated into three species groups (Evans et al. 2005). Morphologically, A. kretschmanni sp. nov. falls into the fumipennis species group based on a complete mesoscutal median sulcus and the presence of a gastral basal carina. In Hellén’s key, the new species keys to A. fumipennis Thomson, 1858 (Hellén 1966). However, A. kretschmanni is easily distinguishable from A. fumipennis by the distinct spines on S7 as well as the lack of prominent tufts of dense hairs along the outer margin of the hind coxae that are diagnostic for A. fumipennis. Further, this new species resembles several species within the Aphanogmus hakonensis complex, i.e., A. amoratus Dessart & Alekseev, 1982; A. captiosus Poasszek & Dessart, 1996, A. goniozi Dessart, 1988; A. hakonensis Ashmead, 1904; A. jarvensis (Girault, 1917); A. manilae (Ashmead, 1904) and A. thylax Polaszek & Dessart, 1996. Shared morphological characters are found mainly on the mesosoma, particularly the sharp circumscutellar carina, the carinate metanotal-propodeal sulcus, the prominent anteromedian projection of the metanoto-propodeo-metapecto-mesopectal complex as well as the paired posterior propodeal projections and the lateral striations on the mesopleuron. All species within the hakonensis complex have an Indo-Australian distribution with a few occurrences in the westernmost Palearctic. They are hyperparasitoids of Hymenoptera that parasitize Lepidoptera Linnaeus, 1758 and can only be determined to species level through male genitalia (Polaszek & Dessart 1996). Recently, the Waterston’s evaporatorium on the 6 th metasomal tergite was discovered to be a taxonomically significant character complex in Ceraphronidae (Ulmer et al. 2021). Major differences in the structure of the Waterston’s evaporatoria of Aphanogmus and Ceraphron Jurine, 1807 were found and are supported by a cladistic analysis, which returned a monophyletic Aphanogmus group and a paraphyletic Ceraphron group (Ulmer et al. 2021). Apart from Aphanogmus s. str., the Aphanogmus group includes the smaller genera Synarsis Foerster, 1878, Gnathoceraphron Dessart & Bin, 1981 and Elysoceraphron Szelényi, 1936 based on striking similarities of the Waterston’s evaporatoria of these taxa. The Waterston’s evaporatorium of the newly described A. kretschmanni sp. nov. lacks campaniform sensilla on T5 and T6 (Fig. 2D), a character that is considered an autapomorphy of Elysoceraphron by Ulmer et al. (2021). However, there are several differences in external morphology that contradict the placement of the newly described species into Elysoceraphron: (1) the mesoscutellum of A. kretschmanni is rounded posteriorly rather than subrectangular, which is the diagnostic character for Elysoceraphron; (2) the head of A. kretschmanni is significantly more transverse, a character shared by most species of Aphanogmus, than that of the Palearctic E. hungaricus Szelényi, 1936 or of the Oriental E. aadi Bijoy & Rajmohana, 2021 with the interocular distance being larger than the eye width (A. kretschmanni: 158:146 µm; E. hungaricus: 152:228 µm; E. aadi: 146:222 µm); (3) the anteromedian projection of the metanoto-propodeo-metapecto-mesopectal complex is straight in A. kretschmanni whereas it is upcurved in Elysoceraphron. The genus Elysoceraphron was first described based on two female specimens of Elysoceraphron hungaricus Szelényi, 1936 collected in Hungary (Szelényi 1936). The male was described two decades later from Czechoslovakia (Masner 1957). Since then, the genus has not received much attention. It appears only briefly in a report adding findings from Sweden and Siberia (Dessart & Alekseev 1980), a few remarks on the taxonomic status of the genus (Masner 1957; Dessart 1975), a short mention in two catalogues (Muesebeck & Walkley 1956; Johnson & Musetti 2004) as well as in keys (Dessart 1962; Alekseev 1978a, 1978b, 1995; Dessart & Cancemi 1987). Recently, a second species, Elysoceraphron aadi, was described from India (Bijoy & Rajmohana 2021). There has
