Abstract:

The aequalis-platensis group of the New World species of Ataenius HAROLD is revised. Twenty seven species are recognised including eight species described as new: Ataenius abancay sp. n., A. borjae sp. n., A. caicarae sp. n., A. cochabambae sp. n., A. guanacastae sp. n., A. guriensis sp. n., A. onkonensis sp. n. and A. pseudoclavatus sp. n. Six new synonyms are proposed: A. aequalis HAROLD, 1880 (= A. insulicola CHAPIN, 1940, syn. n., = A. titschacki BALTHASAR, 1941, syn. n.); A. platensis (BLANCHARD, 1846) [(= A. heyrovskyi BALTHASAR, 1960, syn. n., = A. degallieri CHALUMEAU, 1990, syn. n.)]; A. punctipennis HAROLD, 1868 (= A. subopacus CHAPIN, 1940, syn. n.) and A. setiger BATES, 1887 (= A. pseudohirsutus CARTWRIGHT, 1974, syn. n.) The taxa are diagnosed, keyed and illustrated, available biological information and distribution data are given. A cladistic analysis is presented for the hypothetical relationships among discussed species.
