Abstract

Aphotaenius, and Pseudataenius of the United States and Canada (Coleoptera: Scarabaeidae: Aphodiinae). Smithsonian Contributions to Zoology, number 154, 106 pages, 24 figures, 3 plates, 1974.-All known species are fully described; literature citations, synonyms, and a key to the species are provided; and known distribution is recorded and shown by map figures. All species previously ascribed to the area are listed, and the present status of each is presented. Twenty new species are added to the fauna. Ataenius waltnerhorni Balthasar is transferred to the genus Pseudataenius. The following are placed in synonymy: A. fleutiaui Paulian (=havanensis Balthasar), A. cribratus Van Dyke (= confertus Fall), A. linelli Cartwright (=languidus Schmidt), A. oblongus Horn (=sculptor Harold), A. sulcatula (Chevrolat) and A. frankenbergeri Balthasar (=brevicollis (Wollaston)), A. floridanus Brown and A. solitarius Blatchley {=rhyticephalus (Chevrolat)). Lectotypes are designated for Pseudataenius socialis (Horn), Ataenius insculptus Horn, A. ovatulus Horn, A. cylindrus Horn, A. aequalis Harold, A. sulcatulus (Chevrolat), and A. cognatus (LeConte). Neotypes are established for A. confertus Fall, A nocturnus (Nomura), A. texanus Harold, and A. strigatus (Say). New taxa are Pseudataenius contortus (Florida), Ataenius edistoi (South Carolina), A. parkeri (Arizona), A. rugopygus (Texas), A. duncani (Arizona), A. superficialis (Florida), A. pseudohirsutus (Texas), A. sabinoi (Arizona), A. vandykei (California), A. barberi (Arizona), A. nunenmacheri (Arizona), A. stroheckeri (Florida), A. glaseri (Maryland), A. punctifrons (Minnesota), A. utahensis (Utah), A. hesperius (Arizona), A. sciurus (Florida), A. woodruffi, (Florida), A. griffini (Texas), and A. stephani (Arizona). OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year. SI PRESS NUMBER 4820. SERIES COVER DESICN: The coral Montastrea cavernosa (Linnaeus).

Revision and hypothetical phylogenetic analysis of the species of the New World genus Ataeniopsis (Coleoptera: Aphodiinae: Eupariini)

“…Seven species are found in South America, four in Mesoamerica and in the Sonoran province, three species occur exclu sively in the southeastern United States and one species inhabits the West Indies. This study considerably extends the distribution of Ataeniopsis which is presented in the form of maps, with the exception of species inhabiting the United States of America cited by Cartwright (1974). A generic diagnosis is given below, followed by a cladistic analysis, keys and descriptions.…”

“…Distributed in Sonoran province (Fig. 13), recorded by Cartwright (1974, Fig. 2) from Arizona, California, Colorado, Kansas, New Mexico and Texas.…”

“…The speci mens were taken by light traps on Acacia grassland. (Cartwright, 1974) (Figs 12,19) Ataenius rugopygus Cartwright, 1974: 23-24, Fig. 4.…”

“…The species occurs in the Sonoran province (Fig. 12), recorded by Cartwright (1974, Fig. 4) Diagnostic characters.…”

“…The genus with the type species Ataen iopsis notabilis Petrovitz, 1973 from Brazil, consists of a species complex structurally distinct from other genera of the Eupariini. Woodruff (1973) and Cartwright (1974) placed the North American species in the genus Ataenius Harold, 1867. Chalumeau (1992) treated Ataeniopsis as a subgenus of Ataenius, however, a number of consistent characters appear to warrant generic status.…”
