Labial palps with 4 segments, maxillary palps with 6 segments. Right mandible with basal tooth. Antennae of males bifurcate. Fore wings with 4 cells Rs; cell R open; vein Sc absent; vein 2 r – m present; veins B and M join up at same point on vein R; cell 2 A absent. Cell A of hind wing widely open.

6F6F87E3FF84FD3B5C253617FD1CB560.taxon	materials_examined	Type species: Pampsilota afer Konow, 1899. Body size 5.3 – 15.3 mm. Eyes not convex, inner margins of eyes nearly parallel. Width of head slightly less than width of thorax. Antennae of males simple. Third segment of antennae distinctly compressed and expanded. Fore wings with 4 cells Rs; cell R closed; vein Sc present; vein 2 r – m present; veins B and M join up at same point on vein R; cell 2 A closed; upper margin of cell 3 Rs almost 2.0 times as large as lower. All tibiae without preapical spurs. Saw sheath obtuse in lateral view, width at the base view almost 2.0 times its length in dorsal. Representatives of the genus Pampsilota have a very large morphological diversity of genital structures, which raises doubts about the monophyly of the genus. Liston et al. [2017] suggested that Pampsilota might reasonably be treated as merely a species group within Arge. The genus is distributed in the Palaearctic (East), Oriental and Afrotropical regions. Number of species: World — 8; Palaearctic — 2. Within the Palaearctic, members of Pampsilota have been found only in northern China. For a key to Afrotropical Pampsilota species, see Liston et al.

Right mandible with basal tooth. Antennae of males bifurcate.

Number of species: World — 5; Palaearctic — 1. In the Palaearctic, the genus is known only from Japan, following synonymization of Aproceroides Togashi, 1997 with Schizocerella [Blank et al., 2009].	en	Basov, S. A.

6F6F87E3FF84FD3B5E8E36D7FAB3B62C.taxon	description	Figs 5, 17 – 18. Type species: Spinarge sichuanensis Wei, 1998. Body size 7.2 – 11.9 mm. Antennae of males simple. Fore wings with 4 cells Rs; cell R closed; vein Sc present; vein 2 r – m present; cell 2 A closed. Cell A of hind wing closed. Hind tibiae with or without preapical spurs. Fifth abdominal tergite of male has a long medial process, in females represented by a scarcely noticeable triangular swelling and inconspicuous median groove on tergites 4 – 6. Hind tibia with or without preapical spur. Representatives of this genus are very similar to the closely related genus Arge. Furthermore, whereas the males have a pronounced process of the 7 th tergite, which makes it possible to reliably place them in Spinarge, in females the corresponding character is very weak and in some cases can be confused with folds and deformations of the abdomen caused by drying. In collections, females significantly predominate, while males are rare, which in our experience leads to a large number of erroneous identifications. The genus is distributed in the Palaearctic and Oriental regions. Number of species: World — 13; Palaearctic — 10. Since the publication of the world catalogue of sawflies [Taeger et al., 2010] two new species have been described [Liu et al., 2021; Vasilenko, 2022]. New data on the distribution and biology of members of the genus were also published [Shinohara, Hara, 2012; Shinohara et al., 2016]. Spinarge acutithecata Wei, 2010 and Spinarge xanthofemorata Wei, 2010 have been reported as new taxa [Wu et al., 2010], but their descriptions have not been published to date. They should be considered as nomina nuda. In the latest key to Argidae genera for Europe [Lacourt, 2020], the thesis “ hind tibiae without preapical spurs ” leads to the genus Spinarge. This is erroneous, because, as noted by Hara and Shinohara [2006], only two species actually do not have them, while the rest, including the only one inhabiting Europe, Spinarge metallica (Klug, 1834), have such spurs. This makes it impossible to correctly determine the genus according to that key. In all existing keys for Russia [Gussakovskij, 1935; Zhelochovtsev, 1988], the species of the genus Spinarge are considered as part of the genus Arge.	en	Basov, S. A.

Cell A of hind wing closed. Claws simple. The genus is distributed in the Palaearctic, Nearctic, and Oriental regions. Number of species: World — 42; Palaearctic — 37. Two new species have been recently described from South Korea [Wei et al., 2017]. Rosa multiflora Thunb.

S. brevinerva Wei, 2010 and S. nigrometathoracina Wei, 2010 have been reported as new taxa [Wu et al., 2010] but their descriptions have not been published to date.
