Ancistrocerus balticus Budrys & Orlovskytė in Budrys et al. 2023, Supplement 3: 1, ♀ ♂ (type locality: “ Lithuania, Alytus district, Punios šilas forest, 54°30ʹ48ʹʹN 24°02ʹ22ʹʹE”); holotype, ♀, Nature Research Centre , Vilnius, Lithuania. Syn. nov.

Differential diagnosis. Females of this species can be distinguished from the closely related A. trifasciatus by S 2 in lateral view distinctly convex ( Fig. 1E ; vs. weakly convex to nearly flat in A. trifasciatus , Fig. 1F ). Males can be distinguished by ventral lobe of the aedeagus apically rounded ( Fig. 1G ; vs. rather triangularly pointed in A. trifasciatus , Fig. 1H ). An additional character is the coloration of the hind tibia: usually completely black in the female ( Fig. 2A ) (very rarely with small yellow spot, Fig. 2B ) and completely black ( Fig. 2E ) to at least black dorsally ( Fig. 2F ) in the male. Other characters mentioned in the key by Budrys et al. (2023, Supplement 3) can be also applied but they are also variable and therefore less diagnostic.

Remarks. The identity of Odynerus shibuyai is understood by us following Yamane (1990) and Kim & Yamane (2009); the holotype was not available for study. It is absent from the drawer with the type specimens of taxa described by K. Yasumatsu in the Kyushu University and may be deposited among unsorted material (Toshiharu Mita, personal communication).

Ancistrocerus trifasciatus moeschleri was placed by van der Vecht & Fischer (1972) among synonyms of A. trifasciatus trifasciatus following Blüthgen (1961). The holotype of A. trifasciatus moeschleri was not available for our study; however, its diagnosis, particularly completely black mid and hind legs in the female ( Blüthgen 1938), suggests that it is conspecific rather with A. shibuyai ; therefore, we hereby recognize A. trifasciatus moeschleri as a synonym of A. shibuyai , and not as a synonym of A. trifasciatus . Budrys et al. (2023, Supplement 3: 6) supposed that A. trifasciatus moeschleri was a melanistic variety of A. trifasciatus ; however, this is not so probable because there are no specific conditions (e.g., mountains with high elevation) in the type locality of A. trifasciatus moeschleri . Odynerus shibuyai , A. trifasciatus moeschleri , and O. trifasciatus orientalis were described in the same year. We do not know the exact date of publication for Kostylev’s (1938) paper but his name is anyway invalid due to the homonymy with O. orientalis Dalla Torre, 1889 (Art. 57.2 of ICZN 1999). Among two remaining names, Yasumatsu’s (1938) paper was published in March (dating from Pulawski 2024), while Blüthgen’s (1938) paper was published in May (dating from http://hbs.bishopmuseum.org/dating/sherbornia/konowia.html). Thus, the valid name for the species previously known as both A. trifasciatus shibuyai and A. balticus is A. shibuyai .

Kostylev (1938: 305) indicated the type material of O. trifasciatus orientalis as follows: “Type: ♀ Jakovlevka, Ussuri, 10/IX 1926, Djakonov et Filipjev; ♂ —Jakovlevka, Ussuri, 21/VI 1926, Djakonov et Filipjev”. Therefore, it is unclear whether he designated the female only as the type (the holotype according to Art. 73.1.1 of ICZN 1999) or both specimens (syntypes according to Art. 73.2 of ICZN 1999). He also reported ( Kostylev 1938: 302) that the type specimens of the taxa described in his paper were deposited in ZMMU; however, we failed to find corresponding specimens of O. trifasciatus orientalis in that collection but discovered them in ZISP. These two specimens correspond in full to Kostylev’s description; however, they were not properly labeled. The female specimen is designated here as the lectotype in accordance with Art. 74.7.3 of ICZN (1999), for the purpose of nomenclature stability and correct application of the name O. trifasciatus orientalis .

Budrys et al. (2023: 15; Supplement 3: 6) also supposed that A. balticus could be considered a subspecies of A. shibuyai if further study will reveal their continuous trans-Palaearctic distribution and such a distribution is shown by the present data. We, however, do not support the idea to recognize subspecies in vespid wasps. As introduced by Nixon & Wheeler (1990) and later applied to vespids by various authors (e.g. Carpenter 1988; Tan et al. 2014; Hermes & de Oliveira 2016; Selis 2018; Fateryga et al. 2021; Selis & Carpenter 2023; Selis et al. 2024), the subspecific rank has no place in a taxonomic system based on phylogeny and therefore the numerous taxa considered as subspecies must be revised to ascertain their actual status, whether as simple synonyms or as distinct species.

Distribution. Based on the studied material, the species is confirmed to * Austria, * Ukraine, Russia (*European part, *Urals, *Western Siberia, Eastern Siberia, Far East), * Kazakhstan, Mongolia, Korean Peninsula, and Japan ( Fig. 3 ). Also known from Poland ( Blüthgen 1938, as Ancistrocerus trifasciatus var. moeschleri ), Lithuania ( Budrys et al. 2023, as A. balticus ), and China (North-East) ( Giordani Soika 1986, as A. trifasciatus orientalis ; Kim & Yamane 2009; Tan et al. 2018, both as A. trifasciatus shibuyai ). The distribution of A. shibuyai in Europe is apparently underestimated.
