Makranczy, Gy.: Systematics and phylogenetic relationships of the genera in the Carpelimus group (Coleoptera: Staphylinidae: Oxytelinae)

Perspectives of the classification of the lineages within the Oxytelus and Anotylus groups As it was briefly touched in the introduction of this chapter, the most disturbing problem with the classification of Oxytelini is that the newly discovered taxa cannot be placed in the present system. Some possess features even more extreme than the species currently placed in their own genera today, so it is obvious, that recognition of these taxa as separate genera will eventually lead to the atomization of the Oxytelini. The derived problem with the atomization is the resulting paraphyly of the remaining parts of the genera, which cannot be overcome. As an alternative, lumping the taxa into less genera and recognizing them in a broader sense (with firm and stable delimiting characters) would at least stabilize their nomenclature and ensure the proper naming of the undescribed fauna. The enormous diversity can be dealt with on the level of species groups, which are informal and can be modified without greater nomenclatural consequences. It is hoped that with the consistent implementation of the species group concept throughout the tribe, the phylogeny and evolutionary tendencies of the ancient lineages of Oxytelini will be understood better. The proposed classification is outlined below. Oxytelus GRAVENHORST, 1802 = Caccoporus THOMSON, 1859 = Tanycraerus THOMSON, 1859 = Epomotylus THOMSON, 1859 = Hoplitodes FAUVEL, 1904, syn. n. = Anisopsis FAUVEL, 1904 syn. n. = Par oxytelopsis CAMERON, 1933, syn. n. = Paranisopsis CAMERON, 1938 = Basilewskyorus FAGEL, 1957 = Anisopsidius FAGEL, 1960, syn. n. = Anisopsodes FAGEL, 1960 Characters: diamond shaped scutellar impression; apicomedial hook on aedeagus; lamellar formation on sternite VIII; basolateral ridge on tergite II (plesiomorph). Apocellus ERICHSON, 1839 = Ocaleomorpha FLEISCHER, 1921 = Pheidoloxenides WASMANN, 1925 Characters: spade shaped scutellar impression; neck width less than half of postocular head width; croisant shaped upward projection on sternite VIII; basolateral ridge missing on tergite II.
