Kirejtshuk, A. G.: New species of the genus Physoronia from the Far East and Kryzhanovskiella gen. n. from Australia, with taxonomic notes on the Pocadius complex (Coleoptera: Nitidulidae)

ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Volume 98 Budapest, 2006 pp. 121-132. New species of the genus Physoronia from the Far East and Kryzhanovskiella gen. n. from Australia, with taxonomic notes on the Pocadius complex (Coleoptera: Nitidulidae) A. G. KlREJTSHUK Zoological Institute, Russian Academy of Sciences, St. Petersburg, 199034, Russia E-mail: AK3929@AK3929.spb.edu Abstract - Physoronia taiwanensis sp. n. (Taiwan) and Physoronia intermedia sp. n. (Russian Far East) are described. New synonymy for the taxa Physoronia REITTER, 1884 (= Lordyrodes REITTER, 1884, syn. n., Pocadioides GANGLBAUER, 1899, syn. n.) as well as for Pocadioides gracilis JELÍNEK, 1978 (= Lordyrodes kaszabi KlREJTSHUK, 1984, syn. n.) is established. Kryzhanovskiella gen. n. is proposed for Atarphia aequilibris KlREJTSHUK, 1986 and Atarphia pecki KlREJTSHUK, 1986 (type species). Placement of Omositoides SCHAUFUSS, 1892 in the Pocadius complex of genera is discussed. With 16 figures. Key words - Coleoptera, Nitidulidae, Nitidulinae, Nitidulini, Systematics, new genus, new species, Russian Far East, Taiwan, Australia, synonymy, taxonomy. INTRODUCTION Relationships between species of Physoronia REITTER, 1884, Lordyrodes REITTER, 1884 and Pocadioides GANGLBAUER, 1899 were established by KlREJTSHUK (1997), and his interpretation was later supported and partly revised (JELÍNEK 1999). Nevertheless, even the species described before 1997 do not allow a clear separation of the subgenera. One of the new species described below shares the characters of different "subgenera" and, therefore makes the previous interpretation useless. JELÍNEK (1999) made many valuable remarks on the position of this group; however, its proposed relationship to the genus Ussuriphia KlREJTSHUK, 1992 can scarcely be recognized, because the similarities of these groups are the result of parallel development of some characters rather than of common ancestry (KlREJTSHUK & KVAMME 2002). Ussuriphia is thought to belong in the Phenolia complex, while Physoronia and its other relatives should be placed among the Pocadius complex. JELÍNEK (1999) quite correctly characterized the genus Atarphia REITTER, 1884 and pointed out some inconsistency of the original placement of Atarphia aequilibris KlREJTSHUK, 1986 and A. pecki KlREJTSHUK, 1986.
