Morphogenia: a new genus of the Neotropical tribe Jubini (Coleoptera,Staphylinidae, Pselaphinae) from the Brazilian Amazon

A new genus and species of the large Neotropical pselaphine tribe Jubini is described from Manaus, Brazil, based on material preserved in the Natural History Museum, London. Morphogenia struhli gen. et sp. n. represents the possible sister taxon of the abundant and speciose genus Barrojuba Park, sharing with it the putatively derived condition of anterolaterally shifted vertexal foveae, producing a smoothly convex vertex devoid of fovea or sulci. However, unlike Barrojuba, Morphogenia retains a plesiomorphic antebasal sulcus on the pronotum in both sexes, and additionally lacks elaborate abdominal fovea-like pockets and teeth on the lateral margins of the pronotum that are typical of Barrojuba. The genus is also unusual among jubine genera in lacking the characteristic V- or Y-shaped gular carina. In contrast to the commonly-collected Barrojuba, specimens of Morphogenia are absent in extensive jubine collections housed in museums in the United States, indicating that the new taxon may be relatively scarce or localised.     

Superoxide dismutase in strains of the genus Flavobacterium: isolation and characterization

Two electrophoretically different forms of superoxide dismutase, one of them containing manganese-protein and the other iron-protein, were detected in eleven different strains of the genus Flavobacterium. The activities of the different strains were similar to those described for other bacteria. The two molecular forms of the enzyme differed clearly with regard to activity, electrophoretic behaviour, sensitivity to cyanide and peroxide, and NaCl requirement. Both molecular forms were isolated from Flavobacterium halmephilum. Molecular mass absorption spectra, metal content, optimum pH, heat-sensitivity and stability were described.     

云南鲤科鱼类一新属新种(鲤形目:鲤科:(鱼丹)亚科)

本文记述采自云南澜沧江水系的鲤科(鱼丹)亚科鱼类一新属新种。新属裸(鱼丹)属Gymnodanio gen.nov.在侧线、臀鳍条数目等特征上近似于低线(?)属Barilius,但以其除侧线鳞外体裸露无鳞,具不完全之腹棱等而与其及(鱼丹)亚科现有各属相区别。新种命名为条纹裸(鱼丹)G.strigatus sp.nov.。     

在我国患急性腹泻成人中发现一种新轮状病毒

从3例急性成人腹泻患者粪便中,经电镜观察,成人腹泻轮状病毒—酶联免疫吸附试验(ADRV-ELISA)、普通轮状病毒—酶联免疫吸附试验(Rota-ELISA),猪抗C型(组)轮状病毒和鸡抗D型(组)轮状病毒血清分别与本病毒的免疫电镜试验以及RNA电泳等实验结果,发现了一种新轮状病毒,该病毒的形态结构与普通轮状病毒(Rotavirus)、成人腹泻论状病毒(Adult Diarrhoea Rotavirus,简称ADRV)极为相似,但抗原性与普通轮状病毒(A组),成人腹泻轮状病毒(B组),C型轮状病毒(C组),D型轮状病毒(D组)显然无关。基因分析表明,该病毒基因组由11个双链RNA片段组成,但其RNA电泳图型具有独自的特点,与目前公认的A组、B组、C组、D组论状病毒韵RNA电泳图型均不同,免疫电镜证实,该病毒能被人恢复期血清所凝集,表明该病毒可能是腹泻病人的病因。     

绕茧蜂属寄生于云杉四眼小蠹成虫的—新种记述并附本属世界种检索表(膜翅目:茧蜂科)

绕茧蜂属Ropalophorus Curtis,1837是茧蜂科中的一个小属,迄今世界上仅记载有2种。一种为R.clavicornis(Wesmael),1835,分布于欧州及日本,寄生于云杉八齿小蠹Ips typographus及I.amitinus成虫体内;另一种为R.wisconsinensis Shenefelt,1960,仅分布于美国,由于该种是用诱捕器捕到的,因此,其奇主不详,但有可能为I.pini(Shenefelt,1960)。     

云南蝗虫一新属新种：直翅目：斑腿蝗科

本文记述采自云南省瑞丽地区蝗虫新属龙川蝗属Longchuanacris gen.nov.及新种巨尾片龙川蝗 L.macrofurculus sp.nov.该新属近似于 Pseudogerunda Bey-Bienko.主要区别为前胸背板侧片后缘极凹入;前翅到达第一腹节背板的后缘;后足股节下膝侧片顶刺状:后足附节第3节长度为第1、2节长度之和;雄性腹部末节背板具尾片。     

福建省数种杯叶科吸虫研究及一新属三新种的叙述(鸮形目:杯叶科)

杯叶科是食鱼的爬行类、鸟类、哺乳类寄生的吸虫。本文修订了以往在福建报道的虫种,叙述了一个新属三个新种,取消了前此所定的一个属及种[Tangiella parovipara(Faust and Tang,1938)],认为是存疑的种。本文还报道了盖前冠吸虫 Prosostephanus Tubangu,1922的终末宿主河獭,从而作者(Tang,1941)完成了其生活史的研究。本文比较了从河獭所得的标本与从描、犬所获标本各器官的测量数据,发现由最佳的终末宿住所得标本,其个体及各器官和卵子的测量数据均较大。
