20.500.12556/DiRROS-24864 Revision of Xanthopsis bodracus Makarenko, 1956 (Crustacea: Decapoda) from the Palaeogene of Ukraine Revizija Xanthopsis bodracus Makarenko, 1956 (Crustacea: Decapoda) iz paleogena Ukrajine The present article constitutes a revision of the decapod crustacean species Xanthopsis bodracus Makarenko, 1956 from the early Lutetian (Eocene, Palaeogene) of the Crimean Peninsula, southern Ukraine. The distinctive morphological characteristics of Xanthopsis bodracus enable its classification within the genus Harpactoxanthopsis Via Boada, 1959, as the type series of Xanthopsis bodracus precisely aligns with the diagnostic criteria of this genus. Of the five species in the genus Harpactoxanthopsis, Xanthopsis bodracus is morphologically closest to Harpactoxanthopsis quadrilobatus(Desmarest, 1822). However, there are currently insufficient grounds to confidently synonymise Xanthopsis bodracuswith Harpactoxanthopsis quadrilobatus, as the poorly preserved type material, of which only a part has been preserved, does not allow this. In view of this, Xanthopsis bodracus has been revised as Harpactoxanthopsis sp. The Palaeogene decapod assemblages of Crimea consist of five genera including Coeloma A. Milne-Edwards, 1865, Protocallianassa Beurlen, 1930, Arcticocarcinus Shweitzer et al., 2016, Xanthopsis M’Coy, 1849, and Harpactoxanthopsis Via Boada, 1959. Pričujoči članek predstavlja revizijo vrste deseteronožcev Xanthopsis bodracus Makarenko, 1956 iz zgodnjega lutecija (eocen, paleogen) Krimskega polotoka v južni Ukrajini. Izrazite morfološke značilnosti vrste Xanthopsis bodracus omogočajo njeno uvrstitev v rod Harpactoxanthopsis Via Boada, 1959, saj se tipska serija vrste Xanthopsis bodracus natančno ujema z diagnostičnimi znaki tega rodu. Od petih vrst v rodu Harpactoxanthopsis je Xanthopsis bodracus morfološko najbližje Harpactoxanthopsis quadrilobatus (Desmarest, 1822). Vendar trenutno ni dovolj razlogov za zanesljivo sinonimizacijo Xanthopsis bodracus s Harpactoxanthopsis quadrilobatus, saj slabo ohranjen tipski material, od katerega se je ohranil le del, tega ne omogoča. Glede na to je bil Xanthopsis bodracus revidiran kot Harpactoxanthopsis sp. Paleogensko dekapodno združbo Krima sestavlja pet rodov. Med njimi so Coeloma A. Milne-Edwards, 1865, Protocallianassa Beurlen, 1930, Arcticocarcinus Shweitzer et al., 2016, Xanthopsis M’Coy, 1849, in Harpactoxanthopsis Via Boada, 1959. decapod crustaceans Harpactoxanthopsis Xanthopsis Lutetian taxonomy deseteronožni raki Harpactoxanthopsis Xanthopsis lutecij taksonomija true false true Geološki zavod Slovenije Angleški jezik Slovenski jezik Neznano 2025-12-23 03:58:44 2025-12-23 09:52:57 2025-12-24 04:01:09 0000-00-00 00:00:00 2025 0 0 str. 113-121 no. 2 vol. 68 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-07-30 56 0016-7789 10.5474/geologija.2025.003 261767427 1923-Article_Text-12342641-3-10-20251210.pdf 1923-Article_Text-12342641-3-10-20251210.pdf 1 2463FBC26AF170633D7347599236A7E0 669b9e375aa4d7ee778ec7c839fd03376ce0dbf0735d7e1d36b02fd2867d2f18 014a6164-dfdd-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=37207 Geološki zavod Slovenije Geologija 0 0 0
