Pseudepipona (Pseudepipona) falsa (Kostylev, 1927), stat. resurr. (Figs 5A–J, 10J–M) Odynerus falsus Kostylev, 1927: 80, fig. 5, ♂ (type locality: “Ak-Tash-Gebirge (in Umgebung von Tashkent)” [Uzbekistan]); lectotype (designated here), ♂, ZMMU. Diagnosis. Body with yellow pattern, legs predominantly yellow (Fig. 5A, F); apical margin of female clypeus approximately as wide as distance between antennal sockets, hardly emarginate (Fig. 5B); male F11 very robust, apically truncate, with a submedian tyloid on ventral side (Fig. 5J); antero-lateral angles of pronotum in dorsal view from strongly rectangular to rather blunt (Fig. 5C, D); scutellum and metanotum with yellow bands (Fig. 5A, F); punctation on T2 very coarse and relatively sparse, interspaces exceeding diameter of a puncture (Fig. 5E); paramere moderately broad (Fig. 10J); ventral lobe of aedeagus moderately triangular (Fig. 10M). The species shows variability not only in the shape of the antero-lateral angles of the pronotum but also in the presence of the median expansion of the aedeagus (Fig. 10K, L). Material examined.

Iran, Turkmenistan, Tajikistan, Uzbekistan, Kyrgyzstan, Kazakhstan (Fig. 11). Remarks. Blüthgen (1938: 279) listed this species as a synonym of Euodynerus (Pseudepipona) lativentris, while later he supposed that it might be conspecific with P. beckeri, without mentioning their conspecifity with P. lativentris (Blüthgen 1951: 185). Following Blüthgen, van der Vecht & Fischer (1972: 83) listed O. falsus as a synonym of P. beckeri but with a question. Fateryga et al. (2023: 441) preliminary treated O. falsus within P. lativentris but not P. beckeri. Pseudepipona falsa is considered here a separate species, not a synonym of either P. beckeri or P. lativentris, due to a very distinct morphology of male F11 (a different shape and presence of a tyloid) and a strongly different punctation of the metasoma, especially in the female sex. The report of this species from Crimea by Kostylev (1928: 405) was based on a misidentification of P. beckeri (cf. Fateryga 2018).
