(Type species: Anommatium ashmeadi Mayr, 1904).</p><p>Somaroa Jansson, 1956: 77, 85. (Type species: Somaroa myrmicaria Jansson, 1956). Synonymised by Macek (1989b).</p><p>Erasikea Szabó, 1961: 492; syn. nov. (Type species: Erasikea nutrix Szabó, 1961).</p><p>Remarks. The morphological characters of males indicate that Anommatium is closely related to Pantolyta . The aberrant appearance of Anommatium female is associated with geophilous life mode and has a distinct adaptive value (Macek, 1989b). Most features of Anommatium female mentioned by Macek (1989b) are not unique and independently evolved in other lineages of diapriid wasps, except for two ones, a reduced number of antennal segments (13 or 14) and palpal formula (maxillary palpus one- segmented; labial palpus strongly reduced, represented by a small tubercle). The mentioned two differences are found to be distinctive, supporting a separate taxonomic status of the genera Anommatium and Pantolyta .</p><p>The monotypic genus Erasikea Szabó, 1961 was based on a single female specimen. In the generic diagnosis, Szabó (1961) mentioned that this genus shares some diagnostic characters (i.e. rounded head, missing ocelli, 14-segmented antennae, mesosoma narrower than head, absent wings and tegulae) with Anommatium ashmeadi . Other morphological characters of Erasikea list- ed in the original description are (1) the mesonotum with notauli, (2) posterior two-thirds of the propodeum crooked, hollowed out like a spoon, deeply cut out in the middle, with a small tooth on each side, and (3) the petiole flattened dorsoventrally. We have examined the holotype of Erasikea nutrix and found that actually the notauli on the mesonotum are missing, and the propodeum and petiole are malformed, causing the misinterpretation of characters 2 and 3. Thus, A. ashmeadi is found to be conspecific with E. nutrix, syn. nov., and the genus Erasikea, syn. nov., is a junior synonym of Anommatium .</p></div>	https://treatment.plazi.org/id/03ADA257FFBBFFEF8EAAF9B1D30CFA75	Public Domain	No known copyright restrictions apply.

(Type species: Pantolyta atrata Förster, 1861).</p><p>Acropiesta Förster, 1856: 129, 131, 135; syn. nov. (Type species: Acropiesta flavicauda Ashmead, 1893).</p><p>Pantopiesta Maneral, 1939: 170 . (Type species: Cinetus flaviventris Thomson, 1858). Synonymised by Nixon (1957).</p><p>Remarks. Macek (1993, 1998) revised all known European species of Pantolyta and Acropiesta and discussed the morphological features for distinguishing these two genera. According to Macek, Acropiesta species are characterised by the following characters: (1) mandibles asymmetrical, not prominent (in rest), (2) mouth conus indistinct, (3) labrum almost hidden, stripe-like to level-semicircular, (4) apodemae of aedeagus slightly inflexed anteriorly and not sclerotised, and (5) body length more than 2.5 mm. The genus Pantolyta possesses (1) mandibles almost symmetrical, prominent (in rest), (2) mouth conus pronounced, (3) labrum prominent, triangular, (4) apodemae of aedeagus strongly inflexed anteriorly and sclerotised, and (5) body length less than 2.5 mm.</p><p>Actually, species of the former genus Acropiesta have asymmetrical mandibles (the left one bidentate, the right one tridentate), but similar mandibles are known also in the genus Pantolyta (Fig. 1A). This indicates a considerable variation in the mandibular structures, ranging from asymmetrical to symmetrical state. Pantolyta elegans Chemyreva et Kolyada, 2019 recently described from Japan and the Russian Far East and P. melniki sp. nov.</p><p>have an intermediate shape of the mouth conus and semicircular labrum (Fig. 2B, C). At the same time, all other features mentioned above (characters 1, 4 and 5) testify that P. elegans should be classified as a species of Pantolyta sensu stricto, and P. melniki sp. nov., as a species of Acropiesta . The differences in the male genitalia, i.e. in the degree of sclerotisation and the shape of the apodemae, are also not significant enough to separate these two genera. Moreover, the variation of the latter character is not enough studied. Some undescribed species from Japan possess all characters listed above for the former genus Acropiesta but have the body length about 2.0 mm (Chemyreva, pers. obs.). The body length is found to be more variable in species from the East Palaearctic than in European ones. Thus, we conclude that Acropiesta Förster, 1856, syn. nov., is a junior synonym of Pantolyta Förster, 1856, and the following species of the former genus Acropiesta are transferred here to Pantolyta: P. flavicauda (Ashmead, 1893), comb. nov.; P. flaviventris (Thomson, 1858), comb. nov.; P. flexinervis (Macek, 1998), comb. nov.; P. macrocera (Thomson, 1858), comb. nov.; P. micans (Macek, 1998), comb. nov.; P. nigrocincta (Kieffer, 1909), comb. nov.; P. nitida (Thomson, 1858), comb. nov.; P. pseudosciarivora (Macek, 1998), comb. nov.; P. pulchella (Whittaker, 1930), comb. nov.; P. radialis (Hellén, 1964), comb. nov.; P. rufiventris (Kieffer, 1909), comb. nov.; P. sciarivora (Kieffer, 1907), comb. nov.; P. semirufa (Fouts, 1924), comb. nov.; P. seticornis (Kieffer, 1910), comb. nov.; and P. subaptera (Ashmead, 1893), comb. nov.</p></div>	https://treatment.plazi.org/id/03ADA257FFBAFFE98D1CFD14D5FFFAE2	Public Domain	No known copyright restrictions apply.
