New Paleogene notohippids and leontiniids (Toxodontia, Notoungulata, Mammalia) from the early Oligocene Tinguiririca Fauna of the Andean Main Range, central Chile. (American Museum novitates, no. 3903) Wyss, André R.; Flynn, John J. (John Joseph), 1955-; Croft, Darin A. Here we describe three new notohippid notoungulate species from the early Oligocene-aged Tinguiririca Fauna (Tinguirirican SALMA), recovered from volcaniclastic deposits of the Abanico Formation in the central Chilean Andes, two of which are known from material sufficiently complete to warrant formal naming. These include Eomorphippus bondi, sp. nov., a form of moderate size distinguished by hypsodont incisors and cheekteeth, as well as distinctive proportions of the upper incisors. A closely similar but more diminutive form is described as Eomorphippus neilopdykei, sp. nov. A third previously unrecognized notohippid in the Tinguiririca Fauna, best represented by a large, low-crowned, lower incisor battery, almost certainly represents a new taxon, but remains too fragmentary to warrant naming now. We also propose a new binomial for a previously named notohippid, ?Eomorphippus pascuali, originally described from Gran Barranca in Argentina but which is now also recorded in Chile. This taxon, here named Rosendo pascuali, is markedly less hypsodont than E. bondi and E. neilopdykei and retains lingual cingula on at least p4-m1. As least one leontiniid notoungulate occurs in the Tinguiririca Fauna, Termastherium flacoensis, gen. et sp. nov., best represented by two partial upper cheek toothrows and a tentatively referred maxillary fragment bearing three deciduous teeth. Collectively, description of these new fossils from Termas del Flaco, Chile helps to more fully characterize the Tinguiririca Fauna, facilitating correlation and comparison to other South American land mammal faunas spanning the Eocene-Oligocene transition. 42 pages : illustrations ; 26 cm.

Systematics and analysis of the radiation of Orthotylini plant bugs associated with callitroid conifers in Australia : description of five new genera and 32 new species (Heteroptera, Miridae, Orthotylinae). (Bulletin of the American Museum of Natural History, no. 422) Symonds, Celia L.; Cassis, G. Orthotyline plant bugs inhabiting the southern conifer genus Callitris in Australia are investigated and classified systemically for the first time, with the description of 5 new genera and 32 new species from Australia. The five new callitroid-inhabiting Orthotylini genera proposed are Avititerra, Blattakeraia, Callitricola, Erysivena, and Ngullamiris. The 32 new species accommodated by these genera are: Avititerra lepidothrix, A. xerophila, Blattakeraia actinostrobi, B. hochuli, Callitricola ballina, C. boorabbin, C. cordylina, C. finke, C. finlayae, C. gammonensis, C. graciliphila, C. parawirra, C. pullabooka, C. silveirae, C. tatarnici, C. wiradjuri, C. wollemi, Erysivena apta, E. bundjalung, E. drepanomorpha, E. emeraldensis, E. endlicheriphila, E. kalbarri, E. majori, E. mareeba, E. molloy, E. notodytika, E. paluma, E. schuhi, E. schwartzi, E. sydneyensis, and Ngullamiris whadjuk. A key to the newly described Australian taxa, habitus photographs of all species, illustrations of male and female genitalia, and scanning electron micrographs of representative species are given. A phylogenetic analysis of these callitroid-inhabiting Orthotylini was undertaken, incorporating described Orthotylus Fieber species extralimital to Australia and other recently described Australian Orthotylini. Callitris host plants are mapped to the implied-weights phylogenetic analysis, and their associations are discussed. Associations between related species of Orthotylini and related species of Callitris were detected, as were three independent colonisations by a paraphyletic assemblage of callitroid-inhabiting Orthotylini. Generic concepts within Orthotylini are discussed, with reference to Orthotylus species extralimital to Australia and includes a comparison of key character systems. It is demonstrated that the endosomal spicule characters are primary determinants of generic limits in the Orthotylini, which are supported by other characters of the male and female genitalia and external characters. 226 pages : illustrations (some color), maps ; 26 cm.

Occurrence of Dipleura dekayi Green, 1832 (Trilobita, Homalonotidae) in the Devonian of Colombia. (American Museum novitates, no. 3902) Carvalho, Maria da Gloria Pires de. A large and almost complete dorsal exoskeleton of a homalonotid trilobite from the Middle Devonian of Colombia (Floresta Formation) is described and referred to Dipleura dekayi Green, 1832, confirming prior suggestions of biogeographical affinity between Colombia and the North Eastern Americas Realm during Devonian times. 8 pages : illustrations, map ; 26 cm.

Hirtodrosophila of North America (Diptera, Drosophilidae). (Bulletin of the American Museum of Natural History, no. 421) Grimaldi, David A. Species concepts are morphologically revised and updated for members of the mycophagous genus Hirtodrosophila Duda that occur in America north of Mexico. Photomicrographs of external features, illustrations of male and female terminalia, and detailed descriptions are provided for 12 species. One species, H. cinerea (Patterson and Wheeler) is known only from the original description; its status is uncertain. Species exclusively from the southwestern United States are H. grisea (Patterson and Wheeler), H. longala (Patterson and Wheeler), and H. orbospiracula (Patterson and Wheeler). Hirtodrosophila alabamensis (Sturtevant) and H. duncani (Sturtevant) are widespread throughout the eastern half of North America; the latter species is morphologically disparate for Hirtodrosophila but provisionally retained in the genus. Hirtodrosophila chagrinensis (Stalker and Spencer) is very rare, known only from two female specimens from the northern United States. Hirtodrosophila ordinaria (Coquillett) is the most widespread species of the genus in North America, occurring throughout the northern half of the continent up to Alaska; H. shaitanensis (Sidorenko) from far eastern Russia may be a junior synonym. A preliminary scheme of relationships in the H. melanderi species group (including H. ordinaria) is presented. Two species from Florida (H. pictiventris (Duda), H. prognatha (Sturtevant)) and one from Florida plus other Gulf states (H. thoracis (Williston)) are widespread throughout the Caribbean, Central America, and portions of South America. Hirtodrosophila mendeli (Mourão et al.), from Brazil, may be a junior synonym of H. prognatha. Two new species are described from southern Florida: H. florida, n. sp., and H. jaenikei n. sp., the latter in the nigrohalterata species complex. A key to the North American species is provided. 75 pages : illustrations (some color) ; 26 cm.
