New genus of Meliponini.
Get PDF33 pages : color illustrations, color map ; 26 cm.A new genus of stingless bees (Apinae: Meliponini) is described and figured from Indonesia (Sulawesi), known from a single species previously placed in Geniotrigona Moure. Based on recent phylogenetic studies, Trigona (Geniotrigona) incisa Sakagami and Inoue renders Geniotrigona polyphyletic and is more closely related to Lepidotrigona Moure. The species is transferred to Wallacetrigona Engel and Rasmussen, new genus, and differentiated from Geniotrigona proper as well as all other meliponines occurring in Sundaland, Wallacea, and Sahul (Australinea). The new genus occurs east of the Wallace Line and separate from the distribution of Geniotrigona, which is otherwise restricted to Sundaland, but Wallacetrigona is presently not known beyond the Weber Line. A hierarchical classification of Indomalayan and Australasian stingless bees is tabulated and a revised key to the genera and subgenera provided, as well as an appendix tabulating the species and synonyms. The following new combinations are established: Wallacetrigona incisa (Sakagami and Inoue), Homotrigona (Lophotrigona) canifrons (Smith), Homotrigona (Odontotrigona) haematoptera (Cockerell), Homotrigona (Tetrigona) apicalis (Smith), H. (T.) binghami (Schwarz), H. (T.) melanoleuca (Cockerell), H. (T.) peninsularis (Cockerell), and H. (T.) vidua (Lepeletier de Saint Fargeau)

The taxonomic status of Oligoryzomys mattogrossae (Allen 1916) (Rodentia, Cricetidae, Sigmodontinae), reservoir of Anajatuba hantavirus. (American Museum novitates, no. 3880)
No full text32 pages : illustrations (some color), color map ; 26 cm.Species of the cricetid genus Oligoryzomys are found across most Neotropical biomes, and several of them play important roles as natural reservoirs of hantaviruses and arenaviruses. Here we demonstrate that O. mattogrossae, previously considered a junior synonym of O. microtis, is a valid species, and that it is the oldest available name for specimens previously identified as O. fornesi from Brazil and northern Paraguay. Comparative morphology and phylogenetic analyses based on mitochondrial (cytochrome b) and nuclear (intron 7 of beta-fibrinogen) genes show that O. mattogrossae differs from its sister species O. microtis and from other forms of the genus, corroborating previously published karyological data. Oligoryzomys mattogrossae occurs in Cerrado and Caatinga habitats throughout central and northeastern Brazil and Paraguay, whereas distribution of O. fornesi is apparently restricted to southern Paraguay and northernmost Argentina. Specimens of O. mattogrossae were found to be the natural reservoir of the Anajatuba genotype of hantavirus in northeastern Brazil. Therefore, continuing efforts to delimit Oligoryzomys species and facilitate their identification are important for zoonotic monitoring
New Thai Tetragonula.
No full text17 pages : illustrations (some color) ; 26 cm.A new species of stingless bee (Apinae: Meliponini) is described from workers and two males recovered from nests in tree trunks in Kanchanaburi Province, Thailand. Tetragonula (Tetragonula) malaipanae, new species, resembles T. (T.) laeviceps (Smith), T. (T.) pagdeni (Schwarz), T. (T.) testaceitarsis (Cameron), and similar species, but is particularly similar to T. (T.) drescheri (Schwarz). Unlike T. drescheri, the new species lacks a defined black stripe on the underside of the metafemur, has the metatibia reddish brown to testaceous (rather than uniformly chestnut brown, and black with a yellow mark on the inner surface in T. drescheri). Characters of the uncommonly encountered T. (T.) sarawakensis (Schwarz) are also recorded
New troodontid specimen from Ukhaa Tolgod.
Get PDF47 pages : illustrations (chiefly color) ; 26 cm.A new troodontid dinosaur, Almas ukhaa, from the Late Cretaceous deposits of the Djadokhta Formation at Ukhaa Tolgod, Mongolia, is described here. The holotype specimen (IGM 100/1323) comprises an almost complete and articulated cranium and partial articulated postcranial skeleton. This specimen has a small body size and a short snout as in basal paravians, but it exhibits a number of derived troodontid features that differentiate Almas ukhaa from the Early Cretaceous troodontids reported from China and unite this new taxon with other Late Cretaceous troodontids. Relative to other troodontids, Almas ukhaa is autapomorphic in the presence of a posteriorly curved pterygoid flange, absence of a lateral groove on the anterior part of the dentary, presence of a distinct spikelike process on the ischium, and elongate chevrons. The eggshell associated with IGM 100/1323 can be assigned to Prismatoolithidae indet. based on the smooth surface, eggshell thickness, and microstructural characteristics, and also preserves attributes similar to Protoceratopsidovum minimum. A unique relationship between Byronosaurus and the perinate troodontids IGM 100/972 and IGM 100/974 is no longer supported based on the new observations of Almas ukhaa and Gobivenator
Mammalian diversity and ethnobiology in Peru.
Get PDF118 pages : illustrations (some color), maps ; 26 cm.This report continues our monographic analysis of mammalian diversity and Matses ethnomammalogy in the Yavari-Ucayali interfluvial region of northeastern Peru. Based primarily on specimens collected in the region from 1926 to 2003, interviews with Matses hunters, and published sight surveys of large mammals, we document the local occurrence of 33 species of xenarthrans, carnivores, perissodactyls, artiodactyls (including cetaceans), and sirenians. All of the species in these groups, with the exception of the Amazonian manatee (Trichechus inunguis), are recognized and named by the Matses, from whom we recorded extensive accounts of mammalian natural history. The local xenarthran fauna consists of nine species (Cabassous unicinctus, Priodontes maximus, Dasypus novemcinctus, D. pastasae, Bradypus variegatus, Choloepus hoffmanni, Cyclopes didactylus, Myrmecophaga tridactyla, Tamandua tetradactyla), all of which are represented by examined specimens. Only two xenarthrans (D. pastasae and C. hoffmanni) are primary game species for the Matses, who are familiar with many aspects of their biology that were previously unrecorded in the scientific literature. However, Matses interviews also provide important new information about the behavior of D. novemcinctus (a secondary game species) and M. tridactyla, neither of which has previously been studied in rainforested environments. The local carnivore fauna consists of 16 species (Atelocynus microtis, Speothos venaticus, Leopardus pardalis, L. wiedii, Panthera onca, Puma concolor, Pu. yagouaroundi, Eira barbara, Galictis vittata, Mustela africana, Lontra longicaudis, Pteronura brasiliensis, Bassaricyon alleni, Nasua nasua, Potos flavus, Procyon cancrivorus), most of which are represented by examined specimens; six species without preserved voucher material are known from camera-trap photographs and/or unambiguous sightings by Matses hunters and field biologists. Although the coati (N. nasua) is the only carnivore occasionally hunted by the Matses for food, Matses interviews are richly informative about the natural history of other species, notably including S. venaticus, Leopardus spp., Pa. onca, Puma spp., and E. barbara. All of the local ungulates (Tapirus terrestris, Pecari tajacu, Tayassu pecari, Mazama americana, M. nemorivaga) are hunted by the Matses for food, and the hunters we interviewed are correspondingly well informed about the natural history of most of these species, with the exception of the seldom-encountered gray brocket (M. nemorivaga). Both species of local cetaceans (Inia geoffroyi, Sotalia fluviatilis) are familiar to the Matses, although neither is eaten. The xenarthrans, carnivores, ungulates, and aquatic mammals that inhabit the Yavari-Ucayali interfluve are all widespread species, so this component of the regional fauna, as currently understood, is not biogeographically distinctive, nor is it extraordinarily diverse (by western Amazonian standards). Although we discuss several noteworthy taxonomic and nomenclatural issues relevant to these taxa, the principal contribution of this report consists in the natural history information compiled from our Matses informants and the resulting overview of local community structure as defined by diurnal activity, locomotion, social behavior, and trophic relationships
Burmese amber Evanioidea.
No full text28 pages : illustrations (some color) ; 26 cm.Three new evanioid wasps (Euhymenoptera: Evanioidea) are described and figured from individuals preserved in mid-Cretaceous (earliest Cenomanian) amber from northern Myanmar. The new species represent the families Othniodellithidae and Aulacidae, both previously recorded from Burmese amber. Xenodellitha preta, new genus and species, is the second othniodellithid wasp and the diagnosis of the family is slightly emended in order to accommodate this species. The subfamily Hyptiogastritinae (Aulacidae) is expanded to include Protofoenus Cockerell and a third genus from Burmese amber. Archeofoenus tartaricus, new genus and species, is the third known species of the extinct aulacid subfamily Hyptiogastritinae, differing from Hyptiogastrites electrinus Cockerell in the low position of the discal cell and the open subdiscal cell in the forewing, and from Protofoenus swinhoei Cockerell in the form of the head and mandible, coloration, and forewing venational details. Together, Archeofoenus and Protofoenus are placed in Archeofoenini, new tribe. The last species is similar to the genus Electrofoenus Cockerell, and together they are classified in Electrofoenini among the Aulacidae. Electrofoenops diminuta, new genus and species, is distinguished from Electrofoenus on the basis of wing venation. The significance of these taxa is briefly discussed and a summary of available family-group names among Evanioidea is appended

New genus of Calliopsini.
No full text71 pages : illustrations (chiefly color) ; 26 cm.We establish a new genus for an unusual species of Peruvian calliopsine bees (Panurginae: Calliopsini) that was initially reported in the literature as an undescribed species of Spinoliella Ashmead that purportedly expanded the range of the latter genus beyond Argentina and Chile. Although the new genus superficially resembles Spinoliella, it is easily distinguished by a unique combination of characters in both sexes but particularly in the male hidden metasomal sterna and genitalia. A cladistic analysis of 82 adult external morphological characters including all species of Spinoliella, as well as species of the remaining genera of Calliopsini, suggests that this group is sister to a clade consisting of Spinoliella and Callonychium Brèthes. We describe and illustrate Xeranthrena imponticula Gonzalez and Engel, new genus and species, from males and females collected in xeric areas along the Pacific slopes of the Peruvian Andes. In addition, the phylogenetic study suggests two well-defined clades within Spinoliella and corresponding to the previously recognized subgenera, although we do not advocate for their reinstatement. We briefly discuss new putative synapomorphies for Spinoliella and, building upon prior revisionary work, we describe and figure five new species: Spinoliella aidae Gonzalez, Smith-Pardo, and Engel, new species; S. confusa Gonzalez and Engel, new species; S. propinqua Gonzalez and Engel, new species; S. packeri Gonzalez and Engel, new species; and S. polita Gonzalez and Engel, new species. In addition, we synonymize S. karhadra Rodríguez, Toro, and Ruz under S. rufiventris Toro and Ruz (new synonymy). We provide new geographical and floral records, an identification keys to all 17 recognized species of Spinoliella, and updated key to the genera of Calliopsini
