The Structure of the Endophallus Is a New Promising Feature and a Key to Study of Taxonomy of the Subgenus <i>Metallotimarcha</i> of the Genus <i>Timarcha</i> (Coleoptera, Chrysomelidae) in the Caucasus
A comparative morphological study of the members of the subgenus <i>Metallotimarcha</i> revealed that Caucasian <i>Timarcha hummelii</i> is a separate species, which differs from European members of the subgenus (<i>T. metallica, T. corinthia, T. gibba</i>) by the...

| description | A comparative morphological study of the members of the subgenus <i>Metallotimarcha</i> revealed that Caucasian <i>Timarcha hummelii</i> is a separate species, which differs from European members of the subgenus (<i>T. metallica, T. corinthia, T. gibba</i>) by the internal structure of male aedeagus, namely, manubrium of the endophallus. Morphology of manubrium is described for all species of the subgenus. External characters and the shape of male aedeagus do not permit separating the members of the subgenus distinctly. Examination of both external characters and endophallus structure in the specimens from the Caucasus revealed that <i>T. armeniaca</i> and <i>T. hummelii starcki</i> are the synonyms of <i>T. hummelii hummelii</i>, but not separate species or subspecies. Neotypes of <i>T. hummelii</i> and <i>T. armeniaca</i> are designated. Syntypes of <i>T. hummelii starcki</i> are examined. The key to the species for the subgenus <i>Metallotimarcha</i> is compiled. |
