The New World species of Ataenius Harold, 1867. I. Revision of the A. crenator-group, A. nugator-group and A. perforatus-group (Coleoptera: Scarabaeidae: Aphodiinae: Eupariini)

Abstract:

The crenator-group, nugator-group and perforatus-group of the New Word species of Ataenius HAROLD are revised. Twenty seven species are recognized, including 8 species from South America described as new: A. crenator-group - buenavistae sp.n., tambopotae sp.n.; A. nugator-group - bolivari sp.n., guayasi sp.n., ocumarensis sp.n., pseudocommunis sp.n., tovarensis sp.n.; A. perforatus-group -yungasus sp.n. The 18 previously used names are considered valid, 8 synonoms and one replacement name are proposed as follows: A. arrowi HINTON (= leleupi PETROVITZ, syn. n.); A. chapini HINTON (= frankorum DELOYA, syn. n.); A. crenator HAROLD (= nigritus PETROVITZ, syn. n.), A. nugator HAROLD (= bolivianus HINTON, syn. n., = duplex HINTON, syn. n.); A. opatrinus HAROLD (= narialis PETROVITZ, syn. n., = paraperforatus DELOYA & IBAŃEZBERNAL, syn. n., = woodruffi CARTWRIGHT, syn. п.); A. talpoides nom. n. (= talpa BALTHASAR). A key is provided, each taxon is diagnosed and illustrated, available biological information and distribution data are given. Phylogenetic hypothesis is presented for the relationships among discussed taxa.
