中国螽斯的分类研究I.中国蛩螽族十新种(直翅目:螽斯总科:蛩螽科)

蛩螽族 Meconematini隶属于蛩螽科 Meconematidae,是一类体形较小而纤弱 ,但活动非常敏捷的螽斯。我国记载约 1 0属 72种。俄罗斯直翅目分类学家 Gorochov( 1 993,1 998)对这一类群的分类系统进行了调整 ,根据雄性生殖器的构造 ,建立了不少新属及新亚属 ,并发表了相当多的新种。在 Gorochov确定的属及亚属特征中偏重了雄性的形态特征 ,对雌性和两性共有的一些特征却没有给予归纳 ,至使一部分仅知雌性的种类无法被正确归属。我们将根据现已掌握的材料 ,对一些属和亚属的地位重新进行划分 ,确立 1个较合理的 ,能客观反映其间亲缘关系及演化规律的分类系统。本文根据中国蛩螽族的材料 ,描述 1 0新种 ,分别隶属于优剑螽属 Euxiphidiopsis,东栖螽属 Eoxizicus和新栖螽属 N eoxizicus,其中的优剑螽属 Euxiphidiopsis和东栖螽属 Eoxizicus是由亚属提升为属的地位 ,和新的同物异名 (东栖螽属 Eoxizicus Goro-chov,1 993=亚栖螽属 Axizicus Gorochov,1 998)。原先的副剑螽亚属 Paraxiphid-iopsis Gorochov,1 993看作是优剑螽属 Euxiphidiopsis的 1个亚属。所有模式标本分别保存在中国科学院上海昆虫研究所 ,北京中科院动物研究所 ,天津自然博物馆和广州中山大学昆虫学研究所。

Callionymus omanensis,a new species of dragonet from Oman,north‐western Indian Ocean (Teleostei: Callionymidae)

A new species of deep‐living dragonet Callionymus omanensis from Oman is described on the basis of a single male specimen collected in a trawl from 500 m depth off the coast of Oman. The new species is characterized within the subgenus Bathycallionymus by having a small branchial opening; head short (3·9 in proportion to standard length); eye large (2·4 in proportion to head length); preopercular spine with a long, upcurved main tip, with a small antrorse barb and a larger antrorse spine, and with a strong antrorse spine laterally at the preopercular‐spine base, ventral margin smooth; first dorsal fin slightly higher than second dorsal fin (male); second dorsal fin distally straight; 17 pectoral fin rays; distal end of caudal fin slightly pointed, with two median unbranched rays bearing short filaments; first dorsal fin with basal black spot reaching from first to fourth membranes, third membrane with an ocellated distal black blotch; second dorsal fin with vertical dark grey bars; distal three‐fourths of anal fin black; upper half of caudal fin with oblique dark grey bars; pelvic fin dark grey, second ray basally with a black blotch. The new species is compared with similar species. Revised keys to callionymid species of the western Indian Ocean and the Red Sea, as well as species of the subgenus Bathycallionymus, are presented.     

New species of Tereancistrum Kritsky,Thatcher & Kayton, 1980 (Monogenea: Dactylogyridae: Ancyrocephalinae) from the gills of Prochilodus lineatus (Osteichthyes: Prochilodontidae) from the upper Paraná River floodplain,Brazil

Two new species of Tereancistrum Kritsky, Thatcher & Kayton, 1980 are described from the gills of Prochilodus lineatus (Prochilodontidae) collected from the upper Paraná River floodplain, Brazil. T. toksonum n. sp. is characterised by a slim ventral bar with a sclerotised membrane along the anterior margin. Another characteristic is the dorsal anchor with an elongated deep root. T. curimba n. sp. is similar to T. ornatus Kritsky, Thatcher & Kayton, 1980 but possesses a sclerotised structure between the accessory sclerites of the ventral anchors. Moreover, the accessory anchor sclerites of this new species are longer than those described for T. ornatus.

越南莲座状复苏卷柏一新种——越南卷柏(卷柏科)

该文描述了在越南发现的卷柏科一新种——越南卷柏(Selaginella pseudotamariscina X. C. Zhang & C. W. Chen)。经过分子系统发育分析并与近缘种形态比较,认为该新种是卷柏属(Selaginella)同穗亚属(subg. Stachygynandrum)的一个物种,与S. digitata-S. imbricata分支为姐妹群关系。该新种与卷柏(S. tamariscina)和垫状卷柏(S. pulvinata)的形态近似,其植株均为莲座状,但不同之处在于中叶对称,似披针形,上表面具1沟槽; 孢子叶穗略压扁; 孢子叶和营养叶性状和排列近似,孢子叶非同形,略异形,正置,腹面孢子叶大于背面孢子叶; 背面孢子叶败育,孢子囊仅见于腹面孢子叶基部。     

A new species of Uronychia (Spirotrichea: Euplotida) from Argentina

Uronychia clapsae sp. n. was discovered in an artificial channel that drains an endorheic area from the “sandy Pampa” into the upper basin of Salado River, Buenos Aires, Argentina. This euplotid measures 56–112 μm × 42–70 μm in vivo, is oval in shape and the buccal field is enormous, occupying ca. 80% of body length. It is characterized by having two macronuclear nodules and one micronucleus; usually 10 anterior and invariably three posterior membranelles; right end of paroral hook-like; buccal cirrus base about 3.5–6.0 μm long; invariably four frontal, two ventral, three left marginal, four transverse, and three caudal cirri; six dorsal kineties, kinety 1 with 15–22 dikinetids. Most Uronychia species were recorded in marine habitats, while this new isolate was found in a slightly saline, inland water body. Taxonomic and nomenclatorial concerns on some species assigned to Uronychia are also discussed.

Regional Differences in Striatal Dopamine Uptake and Release Associated with Recovery from MPTP-Induced Parkinsonism

Abstract : This study directly assessed striatal dopamine (DA) uptake rates and peak release in response to KCl in normal, symptomatic, and recovered 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated cats using in vivo electrochemistry. DA uptake rates measured after direct application of known concentrations of DA to the striatum were slowed significantly in both dorsal and ventral striatum in symptomatic cats compared with rates recorded in normal animals. DA uptake rates remained significantly slowed in recovered cats and were not significantly different from the rates recorded in symptomatic animals. In symptomatic cats, both DA uptake rates and the signal recorded in response to KCl stimulation were significantly decreased from normal in all dorsal and ventral striatal regions sampled. Reduction/oxidation (redox) ratios recorded in response to KCl stimulation suggested DA to be the predominant electroactive species. In spontaneously recovered MPTP-treated cats, recordings in the ventral striatum subsequent to KCl stimulation again suggested DA to be the predominant electroactive species released, and peak levels were significantly higher than those recorded in symptomatic animals. In the dorsal striatum of recovered cats, redox ratios recorded subsequent to KCl stimulation suggested serotonin rather than DA to be the predominant electroactive species released. Peak levels of release in the dorsal striatum were not significantly greater than those recorded in symptomatic animals. These results suggest that in spontaneously recovered MPTP-treated cats, there is partial recovery of ventral striatal DAergic terminals, persistent loss of dorsal striatal DAergic terminals, and a down-regulation of DA transporter number/function throughout the striatum. These processes may contribute to volume transmission of DA in the striatum and promote functional recovery.
