Meiodorvillea Jumars, 1974 is a little-known genus of Dorvilleidae Chamberlin, 1919, characterized by its small size and reduced appendages and jaw apparatus. A revision of the genus is presented, ...including analysis of the type material of M. minuta (Hartman, 1965) and M. apalpata Jumars, 1974, as well as specimens collected from shelf and slope continental areas in Brazil. A neotype was designated for M. minuta and its distribution was extended to Brazil. The identity of M. chilensis (Hartmann-Schröder, 1965) is questioned and three new species from 21 to 1,300.7 meters depth are also described. Meiodorvillea penhae sp. nov. has furcate chaeta only in the first anterior chaetigers. In contrast, Meiodorvillea hartmanae sp. nov. has very small palps and asymmetrical thin furcate chaeta and Meiodorvillea jumarsi sp. nov. has dorsal cirri and geniculate chaeta only in the first anterior chaetigers.
A truly continental history in both its geographic and political scope,The Elusive West and the Contest for Empireinvestigates eighteenth-century diplomacy involving North America and links ...geographic ignorance about the American West to Europeans' grand geopolitical designs. Breaking from scholars' traditional focus on the Atlantic world, Paul Mapp demonstrates the centrality of hitherto understudied western regions to early American history.In the first two-thirds of the eighteenth century, imperial officials in London, Paris, or Madrid knew very little about western North America. Yet Europeans' competition to gain access to the Pacific Ocean and control trade to the Far East enhanced the importance of western American territories. Mapp reconstructs French, Spanish, British, and Amerindian ideas about these unknown regions, especially the elusive Northwest Passage, and shows that a Pacific focus is crucial to understanding the causes, course, and consequences of the Seven Years' War.Mapp's work serves as a model for constructing a comprehensive colonial history of the continent. His book transcends artificially imposed boundaries of scholarly inquiry that did not exist in the diverse and interconnected early modern world and relates remote Pacific regions to the Atlantic aspects of the global Seven Years' War.

A new species of the subgenus Pseudoficalbia of the genus Uranotaenia is described from larvae found in a hole in a log at high altitude in montane forest in the Mongar District of Bhutan. Based on ...morphology, the larvae are sufficiently distinct from other species of the subgenus to be described and formally named here as Uranotaenia bhutanensis Somboon, Namgay & Harbach, n. sp.The species is a member of the Bimaculata Series. The chaetotaxy of the fourth-instar larva is provided. Keywords: larva, mosquito, taxonomy
Aleurotulus carapiai Sanchez-Flores & Garcia-Martinez sp. nov. is described. This new species was found in Saltillo, Coahuila, and in Monterrey, Nuevo Leon, Mexico, on the underside of rosemary ...leaves, Syngonium neglectum Schott (Araceae). Microphotographs of morphologica structures of puparium are provided, and separation from other Aleurotulus species is discussed. A key for the species of the genus is proposed.
The genus Takydromus (Squamata: Lacertidae) currently comprises 24 species distributed in East (Eastern Palearctic) and Southeast (Oriental) Asia. Of these 24 species, 15 can be found in China, 8 ...only in the Chinese mainland and adjacent countries or regions, 6 only in Taiwan and 1 (T. kuehnei) on both sides of the Taiwan Strait. Here, we described a new Takydromus species from the suburb of Guilin, northeastern Guangxi, South China, based on morphological and mitochondrial DNA data. From the phylogeny reconstructed with a mitochondrial DNA fragment (CO1 and cyt b), we know that the new species differs from its congeners and that it is a sister taxon to T. intermedius. Morphologically, the new species can be diagnosed from other Takydromus species from the same clade. Based on the above multiple lines of evidence, we suggest that this lacertid lizard from Guilin should be named as a new species, Takydromus guilinensis sp. nov. The discovery of this species increases the total number of Takydromus species to 25, of which 16 can be found in China. During our collecting trip to Guangxi in 2016, we collected ten specimens of the genus Takydromus from the suburb of Guilin, northeastern Guangxi, South China, and found that they did not belong to any currently known species. Here, we described this new species, Takydromus guilinensis sp. nov., based on morphological and mitochondrial DNA (CO1 and cyt b) data. This new species is a sister taxon to T. intermedius with a p-distance of 0.070 in CO1 and 0.080 in cyt b. These two p-distances exceed not only the minimum value (0.067) between T. septentrionalis and T. stejnegeri but also the minimum value (0.079) between T. intermedius and T. yunkaiensis. Morphologically, this new species differs from other currently recognized Takydromus species from the same clade, more evidently in the longitudinal rows of dorsal scales, transverse rows of scales at the mid-body and mensural variables. The description of Takydromus guilinensis sp. nov. increases the total number of Takydromus species to 25, of which 16 can be found in China. Takydromus guilinensis sp. nov. is currently known only from Guilin, Guangxi, South China, where it is sympatric with the other four Takydromus species (T. septentrionalis, T. kuehnei, T. sexlineatus and T. intermedius).
Two new aphid species, Aphis (Toxoptera) fafuensis Cheng & Huang, sp. nov., feeding on Adinandra millettii (Pentaphylacaceae) from Fujian, China, and Aphis (Toxoptera) sennae Cheng & Huang, sp. nov., ...feeding on Senna bicapsularis (Fabaceae) from Yunnan, China, were described. Morphological characters and molecular data supported the taxonomic position of the new species within the subgenus Aphis (Toxoptera). A key for identifying species of apterous viviparous females in this subgenus is provided.
In this study, a new species of the genus Pseudocalotes is described from Yingjiang County, Dehong Dai, and Jingpo Autonomous Prefecture, Yunnan Province, China, based on four female specimens. ...Phylogenetic analyses based on NADH dehydrogenase subunit 2 (ND2) and NADH dehydrogenase subunit 4 (ND4) indicated that the new taxon is different from its congeners. Morphologically, the new species can be diagnosed from the other species by a combination of 18 characters. The recognition of this new species brings the number of described Pseudocalotes species to 22. In this study, a new species of the genus Pseudocalotes is described from Yingjiang County, Dehong Dai and Jingpo Autonomous Prefecture, Yunnan Province, China, based on four female specimens. It can be distinguished from its congeners by the following combination of characters: (1) interoculabials 3 or 4; (2) canthals 5–7; (3) cicrcumorbitals 8–11; (4) 1 scale between rostral and nasal; (5) interparietal 1; (6) superciliaries 4–6; (7) supralabials 6–7, the 1st in contact with the nasal; (8) infralabials 6–8; (9) transverse gular fold and antehumeral fold present; (10) 2–3 enlarged scales between eye and ear; (11) nuchal crest single, consists of 3–5 erected spines; (12) dorsal crest row single, discontinuous and low, located between two keeled, parallel and enlarged scale rows; (13) enlarged postrictals absent; (14) scales around midbody 53–62, dorsal body scales heterogenous in size and shape; (15) midventrals smaller than dorsals; (16) subdigital scales on the 4th finger 20–26, and on the 4th toe 24–29; (17) dorsal background coloration light taupe with four irregular brown patches along the middle of dorsal; (18) inner lips wathet, tongue aurantiacus, throat bluish black. The population from Yingjiang County was nested within a highly supported lineage, formed a sister taxon with P. kakhienensis (SH 97/UFB 100) and according to the p-distance, the new species differed from its congeners by 14.5% to 35.2% for NADH dehydrogenase subunit 2 (ND2) and 15.5% to 25.0% for NADH dehydrogenase subunit 4 (ND4).
