- Polyctesis generic-group Hołyński, 2003 Bellamyina Bílý, 1994 (Figs 6, 19, 20); type species Bellamyina cylindrica Bílý, 1994 (= Polyctesis hunanensis Peng, 1992), by original designation; one species in East Palaearctic (VOLKOVITSH 2006, BELLAMY 2008). Polyctesis Marseul, 1865 (Figs 5, 11, 17, 18); type species Polyctesis rhois Marseul, 1865, by monotypy; one species in West Palaearctic (East Mediterranean), three species in East Palaearctic and Oriental Region. Schoutedeniastes Burgeon, 1941 (substitute name for Schoutedenia Obenberger, 1924, nom. preocc.) (Figs 7–9, 12, 21–26); type species Schoutedenia kerremansi Obenberger, 1924 (= Ptosima magnifica Waterhouse, 1875), by original designation; one species in Afrotropical Region, nine species in Oriental Region and East Palaearctic. Svatactesis gen. nov. (Figs 1–4, 10, 13–16, 27); type species: Polyctesis johanidesi Bílý, 1997, by original designation; one species in West Palaearctic. Formally, Chrysophana and Polyctesis generic-groups can be treated as distinct subtribes but I believe that their establishment prior to a taxonomic revision of the tribe Polyctesini is inappropriate, given the uncertainty regarding taxonomic level and composition of some taxa (e.g. Bellamyina, Schoutedeniastes). HOŁYŃSKI (1993, 2003) indicated that the main distinguishing characters of Schoutedeniastes and Polyctesis are coloration pattern and length of the 2 nd elytral stria. Re-examination of the Schoutedeniastes species has shown that the length of the 2 nd stria varies within the genus (Table 1) which allows the recognition of two groups of species: the S. magnifica / amabilis group (2 nd stria short) and the S. vitalisi group (2 nd stria long). Schoutedeniastes magnifica is the only Afrotropical species of this genus slightly differing from the species attributed to the S. amabilis group in some character states as indicated in Table 1; for this reason it is placed in separate S. magnifica species-group. There are also distinct differences in the male genital structures between the species of S. amabilis and S. vitalisi species-groups (Figs 22–26) but the internal structure of aedeagus of S. magnifica was not studied, externally it is similar to those of S. amabilis species-group (Figs 21–22). The species-group composition of the genus Schoutedeniastes is as follows:
