Taxonomic note on Abax contractus (Heer, 1841) and description of A. parallelepipedus ligurinus n. subsp (Coleoptera, Carabidae, Pterostichini)

摘要

The syntype of Pterostichus contractus Heer, 1841 was examined and its taxonomical position was revised accordingly. The historical interpretation of this taxon as a subspecies of Abax parallelepipedus localized in the area between the Maritime-Ligurian Alps and the northern Apennines is rebutted. The taxon is raised to species level under the name Abax contractus (Heer, 1841), as a senior synonym of Abax continuus Ganglbauer, 1891 n. syn. and A. hypocrita Roubal, 1937 n. syn. The subspecies of Abax parallelepipedus previously reported as subsp. contractus Heer, 1841 is re-described under the name Abax parallelepipedus ligurinus n. subsp.
