Taxonomic revision of Mordellistenahirtipes species complex with new distribution records (Insecta, Coleoptera, Mordellidae)

Abstract. A taxonomic revision of species related to Mordellistenahirtipes Schilsky, 1895 is presented. Five species among the M.hirtipes complex are recognised: M.hirtipes Schilsky, 1895, M.pseudohirtipes Ermisch, 1965, M.purpurascens Costa, 1854, M.balearica Compte, 1985, and M.irritans Franciscolo, 1991. Descriptions, differential diagnoses, an identification key, and new distributional records are provided. Principal Component Analysis is performed for visualisation of differentiation between taxa. The following taxonomic acts are proposed: Mordellistenapodlussanyi Czető, 1990 and M.aegea Franciscolo, 1949 are proposed as junior subjective synonyms of M.hirtipes Schilsky, 1895; M.fageli Ermisch, 1969 and M.pseudohirtipeskrotosensis Czető, 1990 are proposed as junior subjective synonyms of M.pseudohirtipespseudohirtipes Ermisch, 1965; M.geronensis Ermisch, 1977 and M.istrica Ermisch, 1977 are proposed as junior subjective synonyms of M.purpurascens Costa, 1854.
