Two new species of Oxycera (Diptera, Stratiomyidae) from Ningxia, China

Two new speices, Oxycera rozkosnyisp. n. and Oxycera ningxiaensissp. n., are described from Liupanshan Nature Reserve, Ningxia Hui Autonomous Region, Northwest China. All essential diagnostic characters are figured and possible relationships of both taxa are briefly discussed, and a new key to species of Oxycera from China. The type specimens are deposited in the Institute of Entomology, Guizhou University, Guiyang (GUGC).     

Larvae of related Diptera species from thermally contrasting habitats exhibit continuous up-regulation of heat shock proteins and high thermotolerance

A population of Stratiomys japonica, a species belonging to the family Stratiomyidae (Diptera), common name ‘soldier flies’, occurs in a hot volcanic spring, which is apparently among the most inhospitable environments for animals because of chemical and thermal conditions. Larvae of this species, which naturally often experience temperatures more than 40 °C, have constitutively high concentrations of the normally inducible heat-shock protein Hsp70, but very low level of corresponding mRNA. Larvae of three other species of the same family, Stratiomys singularior, Nemotelus bipunctatus and Oxycera pardalina, are confined to different type semi-aquatic habitats with contrasting thermal regime. However, all of them shared the same pattern of Hsp70 expression. Interestingly, heat-shock treatment of S. japonica larvae activates heat-shock factor and significantly induces Hsp70 synthesis, whereas larvae of O. pardalina, a species from constant cold environment, produce significantly less Hsp70 in response to heat shock. Adults of the four species also exhibit lower, but detectable levels of Hsp70 without heat shock. Larvae of all species studied have very high tolerance to temperature stress in comparison with other Diptera species investigated, probably representing an inherent adaptive feature of all Stratiomyidae enabling successful colonization of highly variable and extreme habitats.     

A comparative analysis of the <Emphasis Type="Italic">hsp70</Emphasis> gene system in two species of the family stratiomyidae (Diptera)

The structure of the hsp70 gene cluster was investigated for two species of the family Stratiomyidae (Diptera), Stratiomys singularior and Oxycera pardalina. Their larvae inhabit nearshore-aquatic biotopes with contrasting temperature regimes, composition and concentration of salts. It was shown that the S. singularior hsp70 gene cluster contains five copies and has a compact structural organization (the interval length did not exceed 5 kb). The O. pardalina hsp70 gene cluster contains four copies located at larger distances in comparison with the S. singularior and also includes the hsp68 gene. High variability in the structure of the S. singularior hsp70 gene cluster was detected.     

Spring macrobenthos communities of the Moscow province

Macrozoobenthos communities are described based on material from 70 springs and spring brooks of the Moscow province. The communities include 587 taxa of various origin: 27 rheophiles, 11 crenobionts, 10 ubiquists of small water bodies, and 3 limnophiles. Rheophile species predominate in diversity (52%) and total abundance (41.5%). Crenobionts include Beraea pullata, B. maura, Crunoecia irrorata, Apatania zonella, Parachiona picicornis, Potamophylax nigrocornis, Oxycera pseudoamoena, O. rara, O. pardalina, Pedicia rivosa, Thaumalea testacea; six of these are recorded in the region for the first time. Four types of spring communities are recognised in the region according to the Braun-Blanquet method: with predominant Rhyacophilafasciata and Baetis rhodani (macrorheocrenes), Potamophylax nigroicornis (microrheocrenes), Nemurella pictetii (limnocrenes), and Parachiona picicornis (helocrenes). Three of them are confined to water bodies of different size and flow velocity; one (N. pictetii) is linked to weakly flowing silted wated bodies. Change of spring communities is often observed also downstream due to the distance from the opening of the spring. The structure of rheocrene communities is most similar to that of brooks, that are significantly larger than the rheocrenes. Limnocrene and helocrene communities have no counterparts among communities of other types of water bodies. Some of the specific traits of spring communities fit the island theory and can be explained by it. Comparison of the studied communities with those of springs of Sweden and England reveals wide variance of the general faunistic composition of the communities with a rather stable assortmeont of troglobiot species.     

海南省海口地区龟类市场贸易调查

2002～2004年,对海口地区龟类市场贸易进行了调查。在21个贸易市场共发现龟类23种2572只,其中淡水龟科17种,鳖科4种,陆龟科1种,鳄龟科1种;国外龟类12种,占种数的52％,中国和国外共有龟类11种,占种数的48％;在海南岛分布的龟类有7种,占种数的30％;在23种龟中,10种为濒危物种,1种为易危物种,11种为CITES（2003）附录Ⅱ物种。调查表明,市场上的国外龟类在种类和数量上占绝对优势,一些国家保护龟类也出现在贸易市场上。本文对海口地区龟类市场贸易现状进行了分析和讨论。     

福建平潭岛海域底栖贝类物种多样性及其地理分布

海洋底栖贝类是海洋底栖无脊椎动物的重要代表。福建平潭岛地处台湾海峡西岸北部, 是中国大陆距台湾岛最近之处, 其海域内的底栖贝类区系对了解台湾海峡及其附近海域的生态环境和底栖生物地理格局具有重要意义。本文基于对2015-2018年间中山大学国土资源与环境系在平潭岛海域采集的3,346号底栖贝类标本的鉴定, 结合已发表文献整理出了平潭岛海域底栖贝类名录, 并梳理了各物种在中国近海的地理分布类型。结果显示, 本研究所采标本分属58科122属161种, 其中47种为平潭岛海域新记录。结合历史文献记录, 平潭岛海域共有底栖贝类98科244属395种。其中93.7%的种类在南海亦有分布, 82.0%的种类在东海有分布, 31.1%的种类在黄渤海有分布, 42.3%的种类在台湾岛东部海域有分布。南海-东海分布型种类占区系总种数的49.9%; 其次为南海-黄渤海分布型(27.6%)和南海-台湾海峡分布型(16.2%)。分布限于台湾海峡及其以北的种类仅占总种数的6.3%。研究结果表明, 平潭岛海域底栖贝类区系具典型的亚热带性质, 暖水性种类和广温性种类占主要优势, 与南海北部和东海大陆沿岸地区的关系密切, 与台湾岛周边海域的联系相对较弱。

New records and new synonyms of antlions (Neuroptera, Myrmeleontidae) from China

The antlions from the subfamilies Nemoleontinae and Myrmecaelurinae deposited in the Entomological Museum of the China Agricultural University (CAU) belong to 16 species, among which 11 are recorded for China for the first time. Four species with mostly Oriental distribution are recorded for the first time from the northern localities in Palaearctic China. The Dzungarian faunistic center of antlions with two species recently described from Turan is distinguished. Some species characteristic of Mongolia were found in adjacent China. Occurrence in China of three species, collected by Russian expeditions 100 years ago, is confirmed. Five species described by Yang from China have been synonymized with widely distributed species.
