Inventory of Sarcophaginae (Diptera: Sarcophagidae) for the Humid Chaco,a poorly surveyed ecoregion of South America

ABSTRACT

Sarcophaginae is a large subfamily of sarcophagid flies (Diptera: Calyptratae: Oestroidea: Sarcophagidae) which have diverse habits, mainly sarcosaprophagous, and have forensic and sanitary importance. This is the first work that analyzes the fauna of Sarcophaginae exclusively in the Humid Chaco ecoregion where diversity of flies has scarcely been studied. This inventory was based on: a) samplings at different locations in the province of Chaco, Argentina, and in the state of Mato Grosso do Sul, Brazil; b) examination of entomological collections and c) bibliographic records. Sixty-two species of Sarcophaginae flies are included in this paper, of which 31 species are recorded for the first time in the Humid Chaco ecoregion. Ten species are new records for Argentina, two for Brazil and three for Paraguay. Lepidodexia (Neophytodes) lindneri Townsend, 1931, Lepidodexia (Notochaeta) adelina Mulieri, Schaefer, Duré and González, 2018, Lepidodexia (Pachygraphomima) lenti Lopes, 1980, Oxysarcodexia berthet Dufek and Mulieri, 2017, Oxysarcodexia ibera Dufek and Mulieri, 2017 and Retrocitomyia paraguayensis Lopes, 1985 are registered as endemic species of the Humid Chaco ecoregion. Species with forensically and sanitary importance are listed. Some comments on species distribution previously published in catalogues are provided.     

工矿城市功能定位转变的实证研究——以阳泉市为例

功能定位转变是工矿在持续发展中普遍面临的难题，本文简要讨论了这类城市功能定位转变的意义，并在分析阳泉市经济发展现状及其作为中心城市与腹地的关系基础上，指出山西东部区域中心城市是其新的功能定位，最后提出实现这一目标的对策和措施。     

中原经济区城市流强度时空变化分析

以中原经济区为研究区域,选取2000年和2009年两个时间截面,采用城市流强度模型,对中原经济区28个城市的城市流强度进行测度,根据计算结果将中原经济区28个城市的城市流强度分为高水平平稳型、较高水平增长型、较高水平缓增型等14种类型.结果显示,2000—2009年,中原经济区城市流强度空间整体格局保持不变,呈现围绕郑州、洛阳的圈层结构;中原经济区北部围绕郑州和洛阳形成城市流强度高梯度区域,而南部由于处于经济区边缘,且处于省际地区,为城市流强度低梯度区域,故在南北方向上北高南低;东西方向上,东部受经济近邻效应影响明显,而西部紧靠西部欠发达地区,故城市流强度东高西低;随着时间的变化,经济区核心城市的溢出作用开始凸显.     

A re-examination of 11 species of Otostigmus from the Indo-Australian region described by R. V. Chamberlin based on type specimens in the collection of the Museum of Comparative Zoology,Harvard (Chilopoda; Scolopendromorpha; Scolopendridae)

As a contribution to a revision of the scolopendromorph centipede subgenus Otostigmus of the genus Otostigmus, the type specimens of 11 species described by R. V. Chamberlin from the Indo-Australian region and in the collection of the Museum of Comparative Zoology at Harvard have been redescribed. Of these 11, six are junior synonyms of other Otostigmus species, one is a junior synonym of Rhysida longipes longipes (Newport, 1845) and one a nomen dubium. Only three, namely, Otostigmus amballae Chamberlin, 1913, Otostigmus proponens Chamberlin, 1920 and Otostigmus pamuanus Chamberlin, 1920 are valid.     

Typhlosyrinx -like tropical deep-water turriform gastropods (Mollusca,Gastropoda, Conoidea)

Based on radular and protoconch morphology, the genus Typhlosyrinx Thiele, 1925 has been successively classified in the subfamily Turriculinae of the family Turridae and in the subfamily Clathurellinae of the family Conidae. It is shown that the protoconch had earlier been misinterpreted, and the presence of a diagonally cancellated sculpture indicates a placement in the conid subfamily Raphitominae. Two conchologically similar genera, based on teleoconch sculpture and radular morphology are recognized: Typhlosyrinx, with axial ribbing on teleoconch spire whorls and a radula with long (250 μm) barbed teeth, and Leiosyrinx n. gen., without axial sculpture and a radula with short (<100 μm) simplified teeth. Five species (two new) of Typhlosyrinx and four species (all new) of Leiosyrinx are recognized, all at bathyal depths between 280 and 1840 m in the tropical Indo-Pacific and Panamic provinces. The two genera are not known earlier than the Pliocene, where they already occurred in deep-water assemblages.
