http://digitallibrary.amnh.org/handle/2246/7 The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.

(Bulletin of the American Museum of Natural History, no. 415) Esposito, Lauren A.; Yamaguti, Humberto Y.; Souza, Cláudio A.; Pinto-da-Rocha, Ricardo.; Prendini, Lorenzo. The Neotropical "club-tailed" scorpions of the genus Rhopalurus Thorell, 1876, and two related genera in family Buthidae C.L. Koch, 1837, i.e., Physoctonus Mello-Leitão, 1934, and Troglorhopalurus Lourenço et al., 2004, are revised, based on a simultaneous phylogenetic analysis of 90 morphological characters and 4260 aligned DNA nucleotides from three mitochondrial and two nuclear gene loci. The monophyletic New World buthid subfamily Rhopalurusinae Bucherl, 1971, to which these scorpions were originally assigned, is redefined, revised diagnoses and a key to identification of its genera and species (except for Centruroides Marx, 1890) provided, and their distributions mapped. The paraphyly of Rhopalurus Thorell, 1876, which comprises several monophyletic groups congruent with its disjunct distribution, justifies its relimitation and that of Troglorhopalurus Lourenço et al., 2004, the revalidation of Heteroctenus Pocock, 1893, and creation of Ischnotelson, gen. nov. (type species: Rhopalurus guanambiensis Lenarducci, Pinto-da-Rocha and Lucas, 2005) and Jaguajir, gen. nov. (type species: Rhopalurus agamemnon C.L. Koch, 1839). Ten new combinations are proposed: Heteroctenus abudi (Armas and Marcano Fondeur, 1987), comb. nov.; Heteroctenus bonettii (Armas, 1999), comb. nov.; Heteroctenus garridoi (Armas, 1974), comb. nov.; Heteroctenus gibarae (Teruel, 2006), comb. nov.; Heteroctenus princeps (Karsch, 1879), comb. nov.; Ischnotelson guanambiensis (Lenarducci, Pinto-da-Rocha and Lucas, 2005), comb. nov.; Jaguajir agamemnon (C.L. Koch, 1839), comb. nov.; Jaguajir pintoi (Mello-Leitão, 1932), comb. nov.; Jaguajir rochae (Borelli, 1910), comb. nov.; Troglorhopalurus lacrau (Lourenço and Pinto-da-Rocha, 1997), comb. nov. Three new species are described: Ischnotelson peruassu, sp. nov. (type locality: Parque Estadual do Peruassu, Minas Gerias, Brazil); Physoctonus striatus, sp. nov. (type locality: Castelo do Piauí, Piauí, Brazil); Rhopalurus ochoai, sp. nov. (type locality: San Agustín, Edo. Zulia, Venezuela). Fifteen new junior subjective synonyms are proposed: Rhopalurus acromelas Lutz and Mello, 1922, Rhopalurus melleipalpus Lutz and Mello, 1922, Rhopalurus iglesiasi Werner, 1927, Rhopalurus lambdophorus Mello-Leitão, 1932, Rhopalurus dorsomaculatus Prado, 1938, and Rhopalurus goiasensis Prado, 1940 = Jaguajir agamemnon (C.L. Koch, 1839); Rhopalurus pintoi kourouensis Lourenço, 2008 = Jaguajir pintoi (Mello-Leitão, 1932); Rhopalurus crassicauda Caporiacco, 1947, Rhopalurus amazonicus Lourenço, 1986, and Rhopalurus crassicauda paruensis Lourenço, 2008 = Rhopalurus laticauda Thorell, 1876; Rhopalurus melloleitaoi Teruel and Armas, 2006, and Rhopalurus aridicola (Teruel and Armas, 2012) = Heteroctenus junceus (Herbst, 1800); Rhopalurus granulimanus Teruel, 2006 = Heteroctenus gibarae (Teruel, 2006); Rhopalurus virkii Santiago-Blay, 2009 = Heteroctenus abudi (Armas and Marcano Fondeur, 1987); Rhopalurus brejo Lourenço, 2014 = Troglorhopalurus lacrau (Lourenço and Pinto-da-Rocha, 1997). 134 pages : illustrations (some color), maps ; 26 cm.

(Bulletin of the American Museum of Natural History, no. 413) Bai, Bin, 1981-; Meng, Jin (Paleontologist); Wang, Yuan-qing.; Wang, Hai-bing.; Holbrook, Luke. The middle Eocene ceratomorph Hyrachyus has been considered a pivotal genus in ceratomorph evolution, either as a transitional form from tapiroids to rhinocerotoids, giving rise to all later rhinocerotoids, or else as the sister taxon to other rhinocerotoids. Thus, Hyrachyus has been commonly chosen as an outgroup in phylogenetic analyses of rhinocerotoids. However, little has been published on the osteology of Hyrachyus, even though well-preserved craniodental and postcranial specimens of this taxon have been in collections for decades. Here, we describe and illustrate the cranial and postcranial osteology of Hyrachyus modestus, based mainly on the exceptionally preserved specimens housed at the American Museum of Natural History, specifically AMNH FM 12664. Our bone-by-bone description provides detailed information on the osteological morphology of Hyrachyus, which should be useful for phylogenetic analyses of both rhinocerotoids and perissodactyls in general, because it provides one of the more complete and best-preserved examples of the skeleton of an earlier Eocene perissodactyl.... 68 pages : illustrations ; 26 cm.

(Bulletin of the American Museum of Natural History, no. 412) González, Víctor H.; Smith-Pardo, Allan H.; Engel, Michael S. 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. 71 pages : illustrations (chiefly color) ; 26 cm.
