Lernanthropus antofagastensis sp. nov. (Copepoda: Lernanthropidae) parasitic on Anisotremus scapularis in Chilean waters,and new records of Lernanthropus trachure (Brian, 1903)

Lernanthropus antofagastensis sp. nov., parasitic on Anisotremus scapularis, and inshore fish of Antofagasta, Chile, is described and illustrated. It resembles five other species of Lernanthropus in its dorsal plate and third leg, but can be distinguished from them by a combination of characters. L. trachuri Brian, 1903, is recorded, its male described and illustrated from specimens collected from Seriolella violacea and Trachurus murphy, taken in the same locality.     

A new species of Munromyia Bezzi (Diptera: Tephritidae) reared from Chionanthus battiscombei (Oleaceae) in northern Kenya

Munromyia marsabitensis sp. nov. is described from the isolated mountains of Marsabit in northern Kenya. It can be distinguished from the two known congeners by the thoracic and abdominal colour patterns, structure of the male and female terminalia, and host plants. Larvae are seed predators, developing within the green, aborted fruits of Chionanthus battiscombei. Over 70% of sampled fruits (n?=?74) were infested with larvae, but nearly all of the individually infested fruits (96.1%) produced only one adult tephritid. Bactrocera biguttula, but not M. marsabitensis, was reared from ripe fruits of the same plant.     

First record of the genus Tanaostigma (Hymenoptera,Chalcidoidea, Tanaostigmatidae) from the Afrotropical region with description of three new species

ABSTRACT

The genus Tanaostigma is newly recorded from the Afrotropical region and three new species are described: Tanaostigma lasallei van Noort sp. nov. (South Africa), Tanaostigma mulu van Noort sp. nov. (Kenya) and Tanaostigma ukumbusho van Noort sp. nov. (Kenya). We provide comprehensive images of the holotypes and an illustrated identification key to the African species. New country distribution records are provided for Tanaostigmodes tambotis Prinsloo & LaSalle, 1995. All images presented here as well as supplementary images and online keys are available on www.waspweb.org

Bio-sketches and partitioning of sympatric reed frogs,genus Hyperolius (Amphibia; Hyperoliidae), in two humid tropical African forest regions

Sympatric reed frog species were studied in Gabon (Monts Cristal: Hyperolius mosaicus, H. pardalis, H. tuberculatus) and Kenya (Kakamega Forest: Hyperolius acuticeps, H. cf. cinnamomeoventris, H. kivuensis, H. lateralis, H. viridiflavus). For each taxon, a standardized diagnosis covering 11 aspects of adult and in part tadpole morphology as well as the sequence of a 560 bp fragment of mitochondrial DNA of the 16S ribosomal gene are provided. In addition, behavioural data are given for each species including measurable parameters of advertisement calls. The Monts Cristal Hyperolius species clearly differ in their spatial arrangement through the choice of breeding site. Hyperolius species at the Kakamega Forest share the same breeding sites but in part differ in their activity pattern throughout the year. Advertisement calls of sympatric species in both regions mainly differ in temporal parameters.     

New and little known oribatids from Kenya,with descriptions of two new genera (Acari: Oribatida)

A list of newly collected and identified oribatids from Kenya is presented, two of them represent new genera; Sceletoppia gen. nov. (Oppiidae) and Mahnertozetes gen. nov. (Haplozetidae). Twelve species, belonging to the families Steganacaridae, Lohmanniidae, Tetracondylidae, Microzetidae, Zetomotrichidae and Galumnidae are new to science. Taxonomical notes on two other species are given.     

Two new species of freshwater crabs from Mount Elgon,East Africa (Brachyura: Potamoidea: Potamonautidae) and a re-diagnosis of Potamonautes niloticus (H. Milne Edwards, 1837) with notes on their natural history and onchocerciasis

Two new species of potamonautid freshwater crabs from eastern Uganda, Africa are described, and Potamonautes niloticus (H. Milne Edwards, 1837) is re-diagnosed with key characters illustrated photographically. A total of four species of crabs are now known to occur on Mount Elgon, which borders both Kenya and Uganda. Two of these species are endemic to the mountain and the distribution patterns of all four species indicate a distinct altitudinal preference. All taxa are compared with similar species and their distributions and natural history are reviewed. Furthermore, three of the crabs recorded from Mount Elgon have been implicated in the transmission of onchocerciasis in East Africa.     

肯尼亚红碎茶与滇红工夫香气成分比较分析

采用固相微萃取(Solid Phase Microextraction,SPME)和气相色谱-质谱(GC-MS)对五个肯尼亚红碎茶和我国的滇红工夫进行香气成分的比较分析.从六个茶样中一共检测出152种香气成分,其中1号茶样59种,2号茶样66种,3号茶样52种,4号茶样61种,5号茶样63种,滇红工夫58种.滇红工夫、1号、5号和3号茶样以醇类化合物的相对含量最高,分别占主要香气成分总量的60.71%,50.76%,47.33%和37.13%.2号和4号茶样以醛类化合物的相对含量最高,分别占42.52%和36.57%.参照Owuor香气指数(F1),1号、5号和滇红工夫茶样的F1值最高,其次是3号茶样,2号和4号茶样的F1值较低.F1值越高的红茶,其香型较好,这与实际茶叶审评中香气审评结果一致.     

2001-2011年肯尼亚植被与降水时空变化特征及其相关性分析

利用2001-2011年间MOD13Q1-NDV I以及TRMM 3B43月降水数据,分析肯尼亚地区11年来植被NDV I与年降水的年际变化趋势及其相关关系.结果表明肯尼亚地区植被NDV I总体上呈轻微下降趋势,且存在着显著的空间差异,3.90%的地区植被NDV I显著增加,15.53%的地区NDV I呈显著减少.肯尼亚地区年降水量总体上呈轻微下降趋势,且存在着显著的空间差异,3.29%的地区年降水量呈显著或低度增加,19.05%的地区年降水量呈显著或低度减少,77.66%的研究区域年降水量基本无变化.肯尼亚地区的植被NDV I与降水有着很好的相关性,93.50%的区域植被NDV I和降水呈正相关,有41.67%的地区呈显著水平以上相关,6.50%的区域植被NDV I和降水呈负相关,仅有0.35%的地区呈显著负相关.
