    59 pages : illustrations (some color) ; 26 cm. Part of the oonopid PBI project. (Acknowledgments)Three new genera of soft-bodied, oonopine goblin spiders are established. Two specific names (Oonops tolucanus Gertsch and Davis, Oonops chickeringi Brignoli) are transferred to the new genus Toloonops, characterized by retaining a separate palpal bulb and cymbium, having the cymbial cone near the cymbial margin, and having posteriorly directed projections on the male endites that originate far from the anterior endite margins; five new species are described: T. chiapa, T. jacala, T. veracruz, T. belmo, and T. verapaz. Six similar new species, united by having a stepped male endite profile and a subapical sclerite on the anterior genitalic process of females, are assigned to the new genus Guatemoonops: G. purulha, G. rhino, G. jaba, G. chilasco, G. augustin, and G. zacapa. Oonops mckenziei Gertsch is transferred to the new genus Emboonops, characterized by having a fused palpal bulb and cymbium, a hypertrophied embolus, and often a V-shaped female anterior genitalic process; nine new species are described: E. tuxtlas, E. tamaz, E. catrin, E. nejapa, E. calco, E. palenque, E. bonampak, E. arriaga, and E. hermosa

    New genera and species of Plokiophilidae from Australia, Fiji, and Southeast Asia, with a revised classification of the family (Insecta, Heteroptera, Cimicoidea). (American Museum novitates, no. 3825)

    24 pages : illustrations (some color) ; 26 cm.Monteithophila queenslandana, new genus and new species, is described from Queensland, Australia, and represents the first record of the family Plokiophilidae from the continent. Morphology of the male genitalia is similar to that found in Heissophila Schuh from Thailand and therefore the traumatic insemination as found in other members of the family is hypothesized to be absent in Monteithophila. The female of an apparently congeneric taxon from Fiji is described as Monteithophila fijiensis. Paraplokiophiloides schwendingeri, new genus and new species, is described from Thailand. Female genitalic morphology in the Plokiophilidae is documented with laser confocal microscopy. A revised classification of the Plokiophilidae is proposed in order to establish congruence between observed morphological characters and the recognized higher-taxonomic groupings. The new subfamily Heissophilinae is erected to include Heissophila, Moneithophila, and the Baltic amber fossil Pavlostysia Popov. The concept of Plokiophilinae is revised to include all taxa with traumatic insemination. The tribe Lipokophilini is erected to contain the Recent genus Lipokophila Štys. A newly delimited Plokiophilini includes the subtribes Embiophilina and Plokiophilina; Paraplokiophiloides is placed in the Embiophilina based on the presence of fore- and mesofemoral spines. Defining characters of the Plokiophilidae are discussed and a key to the genera is included

    12 pages : illustrations (some color) ; 26 cm.A nest of the leaf-cutter bee Notanthidium (Allanthidium) chilense (Urban) (Anthidiini) is described and illustrated, the second such account for the genus. The nest, presumably constructed from resin, consisted of four cells and was attached to a stem of the plant genus Baccharis (Asteraceae) in the high Andes of northern Chile. The cells held two postdefecating larvae, a male pupa, and an emerged adult female, all in cocoons, permitting the first descriptions of the immature stages and cocoon for the genus. To the extent possible the immatures are compared with those of other tribal members

    New ctenodactyloid rodents from the Erlian Basin, Nei Mongol, China, and the phylogenetic relationships of Eocene Asian ctenodactyloids. (American Museum novitates, no. 3828)

    58 pages : illustrations ; 26 cm.During the last decade, numerous ctenodactyloid rodent fossils have been systematically collected from at least six horizons of the strata that are distributed from the upper part of the Nomogen Formation to the lower part of the Irdin Manha Formation in the Huheboerhe-Nuhetingboerhe area of the Erlian Basin, Nei Mongol (Inner Mongolia). The ages of these fossiliferous horizons range from the Earliest Eocene to the Middle Eocene. These fossils represent the best-known ctenodactyloid assemblages with a high species diversity and reliable stratigraphic and chronological constraints from one locality in central Asia. The fossils show a relatively continuous record of ctenodactyloids and the earliest radiation of rodents in central Asia beginning from the earliest Eocene. These data are important for biostratigraphic correlation of the Paleogene in central Asia and for understanding the taxonomy of Asian ctenodactyloids and the earliest diversity and evolution of rodents. Among the new fossils, we recognized 10 species that belong to six genera and three morphotypes. Of these taxa, three new genera and species, Chenomys orientalis, gen. et sp. nov., Simplicimys bellus, gen. et sp. nov., and Yongshengomys extensus, gen. et sp. nov., are described. In addition, three new species of Tamquammys, T. robustus, sp. nov., T. longus, sp. nov., and T. fractus, sp. nov., and one new species of Yuomys, Y. huheboerhensis, sp. nov., are also named. With these new materials, we are able to briefly review some existing problems in the taxonomy of early ctenodactyloids, which has remained a difficult task in the study of this Asian rodent group. In light of the new material and taxonomic review, we conducted phylogenetic analyses of ctenodactyloids using a data matrix that contains 38 taxa and 81 characters. Our analysis shows that Chenomys, Tamquammys, and Simplicimys are placed at the base of the clade that contains the extant Ctenodactylus. Yongshengomys is the only taxon that is deeply placed within the clade containing the extant Ctenodactylus and clustered with Chuankueimys and Tsinlingomys. Our analysis supports Gobiomyidae and Ctenodactylidae as monophyletic groups, respectively, but shows that other families and subfamilies traditionally recognized, such as Cocomyinae, Advenimurinae, Tamquammyidae, Yuomyidae, and Chapattimyidae, are probably paraphyletic

    A new species of Monodelphis (Didelphimorphia, Didelphidae) from the Brazilian Atlantic Forest. (American Museum novitates, no. 3832)

    15 pages : illustrations (some color), map ; 26 cm.A new species of the didelphid marsupial genus Monodelphis is described from southeastern Brazil. The new species is closely related to Monodelphis kunsi Pine, 1975, and other members of the M. adusta group, but differs from those species and from other congeneric taxa by unique external and cranial characters and by cytochrome-b and nuclear DNA sequences. Diagnostic morphological characters of the new species include uniformly brownish dorsolateral pelage without distinct stripes or other sharp pigment discontinuities; diminutive eyes and ears; a remarkably long and narrow rostrum; apparent loss of an interparietal ossification; and the presence of diastemata between C1 and P1, P1 and P2, c1 and p1, p1 and p2, and p2 and p3. The new species is known from the Atlantic Forest (Mata Atlântica) of southeastern Brazil, where it occurs sympatrically with four other congeners (M. americana, M. iheringi, M. scalops, M. dimidiata) and seems to be restricted to montane habitats

    A new species of scaphitid ammonite from the Lower Maastrichtian of the Western Interior of North America, with close affinities to Hoploscaphites constrictus Sowerby, 1817. (American Museum novitates, no. 3833)

    40 pages : illustrations (1 color), map ; 26 cm.We describe a new species of scaphitid ammonite from the Upper Cretaceous (Lower Maastrichtian) of North America. Hoploscaphites sargklofak, n. sp., is endemic to the U.S. Western Interior, but closely resembles H. constrictus Sowerby, 1817, from the Maastrichtian of northern Europe

    Sicariomorpha, new goblin spider genus.

    Get PDF
    14 pages : illustrations (some color) ; 26 cm.A new genus of oonopid spider, Sicariomorpha Ott and Harvey, is named for the type and only known species, Gamasomorpha maschwitzi Wunderlich from Malaysia. The most striking feature of the spider is the eyes, which are arranged in two widely separated triads. Besides taxonomic description, we summarize the biology of Sicarimorpha maschwitzi, which is a kleptoparasite of the Southeast Asian army ant Leptogenys distinguenda (Emery) and one among only few well-studied myrmecophilous spiders. Its morphology, behavior and life history seem to be well adapted for the life with its predatory army ant host
