The strigicauda-group of the six New World species of Ataenius HAROLD is revised. A lectotype of Ataenius vexator HAROLD is here designated, the following new synonyms are proposed: Ataenius columbicus HAROLD, 1880 (= A. tesari BALTHASAR, 1947, syn. n.); A. heinekeni WOLLASTON, 1854 [(= A. rhyticephalus (CHEVROLAT, 1864) syn. n., = A. vexator HAROLD, 1869, syn. n.] and A. strigicauda BATES, 1887 (= A. aspericollis PETROVITZ, 1973, syn. n.). The taxonomic history of the species-complex, diagnostic characters and key are provided, available biological information and distribution data are given.

A new genus and species of Aulonocneminae from India with notes on comparative morphology

Twelve species of Aphodiinae are listed from Sabah: Saprosites crockerensis sp. n. is described and illustrated, Ataenius kelatianus Balth. is synonymized with A. orbicularis A. Schm. Information is added on the distribution of each species. By the courtesy of Dr. Ivan Lobi I had the opportunity to study the Aphodiinae from Sabah (NE Borneo) collected by him and Dr. Daniel Burckhardt in 1987 and by Dr. Ales Smetana in 1988. Even though small, the material is interesting from a biogeographical point of view. Material was examined from following collections: National Museum, Prague (NMP), Muséum d'Histoire naturelle, Genève (MHNG), Institute of Systematic and Experimental Zoology, Krakow (ISEZ). The material is deposited in the MHNG excepted where stated. Aphodius (Pharaphodius) diadema Wiedemann (Figs 1-2) Material examined.

The complicatus group of the New World species of Ataenius HAROLD is revised. Sixteen species are recognized including four species described as new: A. pearlensis sp. n. from Panama, A. quintanaroo sp. n. from Mexico, A. saulensis sp. n. from Guiana and A. vinacoensis sp. n. from Argentina. The 12 previously used names are considered valid, two new synonyms are proposed: Ataenius steinheili HAROLD (= A. grenadensis CHALUMEAU, syn. n.) and A. beattyi CHAPIN (= A. cameneni CHALUMEAU & GRUNER, syn. n.). The taxa are diagnosed, keyed and illustrated, available biological information and distribution data are given.

type of Ataenius arator Harold is designated, and the following new synonyms are proposed: Auperia Chevrolat (= Phalangochaeta Martinez syn. n.); A. transversaria (Schmidt) (= Euparia bolivari Petrovitz syn. n.); A. denominata Chevrolat (= Ataenius arator Harold syn. n. = Ataenius benjaminbanderai Islas syn. n. = Ataenius euglyptus Bates syn. n. = Ataenius sciurus Cartwright syn. n. = Phalangochaeta grandis Petrovitz syn. n.).A key is provided, each taxon is diagnosed and illustrated, available biological information and distribution data are given. A taxonomic background of the genus is included and phylogenetic hypothesis is presented for the relationship among discussed taxa.
