The taxonomy of European Aegomorphus genus was for years relatively simple, with two known species only - a common pan-European Aegomorphus clavipes (Schrank, 1781) and rare Aegomorphus krueperi Kraatz, 1859 from Balcan peninsula (Greece, Bulgaria). A new species, Aegomorphus francottei was described by Gianfranco Sama in 1994 also from Balcan peninsula [❖]. Situation become complicated after description of the fourth species by Jacek Hilszczański and Cezary Bystrowski in 2005, Aegomorphus wojtylai, from Poland [✧]. This interesting species, very close relative to Aegomorphus clavipes, was eventually synonymized with Aegomorphus obscurior Pic, 1904, and Aegomorphus francottei was moreover reported also from Poland [✧].
Enigmatic Aegomorphus obscurior, in reality widespread Eurasian species, has been probably only overlooked or misidentified as generally known sympatric Aegomorphus clavipes. After description of synonymic Aegomorphus wojtylai, the species has been recorded from many localities in Russia from Moscow to the Far East, from Kazakhstan [✱], and also from Latvia and Mongolia.
