【摘要】 长角蚁甲属团隶属于鞘翅目,隐翅虫科,蚁甲亚科,苔蚁甲族。该属团物种外形很接近,个体较小,属于捕食性昆虫,共包括九个属,分别是:长角蚁甲属Pselaphodes,拟蚁甲属Labomimus,安蚁甲属Linan,毛蚁甲属Lasinus,拟毛蚁甲属Paralasinus,野村蚁甲属Nomuraius,印度长角蚁甲属Indophodes,瑶蚁甲属Dayao和台湾长角蚁甲属Taiwanophodes。成员多栖息于山林中近水的潮湿落叶层和枯木中,水边丛生的杂草和青苔中,主要以跳虫、蠕虫等土壤节肢动物为食物,对温度和湿度的变化较为敏感,可以作为监测环境的重要指标,在生态系统的食物链和食物网中发挥重要作用。此前,长角蚁甲属团全世界共记载171种,以东洋区的分布为主,个别物种散布在古北区。本研究之前,长角蚁甲属团在东南半岛,印度等地尚缺少足够研究。本研究检视了500头左右的标本,采用形态学分类的传统途径,对标本进行了准确且系统地分类和总结,得到如下结论:一.共鉴定长角蚁甲属团37种,包括长角蚁甲属22种,拟蚁甲属12种,拟毛蚁甲属1种,台湾长角蚁甲属1种,安蚁甲属1种。发现新物种有21种(部分已见刊),分别是:空穴拟蚁甲Labomimus cavicornis sp.nov(越南,泰国)、库蓬拟蚁甲Labomimus cucphuong sp.nov(越南)、怀孔拟蚁甲Labomimis huaykonatus sp.nov(泰国)、帕拉尼拟蚁甲Labomimus palaniensis sp.nov(印度)、里德尔拟蚁甲Labomimis riedeli sp.nov(爪洼)、斯里兰卡拟蚁甲Labomimus Srilankensis sp.nov(斯里兰卡)、苏门答腊拟蚁甲Labomimis sumatranus sp.nov(印度尼西亚)、班帕巴特长角蚁甲Pselaphodes banphabat sp.nov(老挝)、武吉拉鲁特长角蚁甲Pselaphodes bukitlarutus sp.nov(马来西亚)、大叻长角蚁甲Pselaphodes dalatensis sp.nov(老挝)、大吉岭长角蚁甲Pselaphodes darjeeling sp.nov(印度)、个旧长角蚁甲Pselaphodes gejiuensis sp.nov(中国)、詹德克长角蚁甲Pselaphodes jendeki sp.nov(越南)、卡里甘达基长角蚁甲Pselaphodes kaligandaki sp.nov(尼泊尔)、卡西山长角蚁甲Pselaphodes khasiensis sp.nov(印度)、盘突长角蚁甲Pselaphodes laminatus sp.nov(中国)、蓝湖长角蚁甲Pselaphodes nongfa sp.nov(老挝)、奥莱萨长角蚁甲Pselaphodes olexai sp.nov(越南)、拟梳长角蚁甲Pselaphodes parapectinatus sp.nov(越南)、钝长角蚁甲Pselaphodes retunus sp.nov(印度)、小白龙长角蚁甲Pselaphodes xiaobailongensis sp.nov(中国)。共发现新记录16种,陕西新记录:川拟蚁甲Labomimus sichuanicus、突长角蚁甲Pselaphodes aculeus、野村氏长角蚁甲Pselaphodes nomurai;尼泊尔新记录:棘长角蚁甲Pselaphodes spinosus;印度新记录:墨脱拟蚁甲Labomimus medogensis;老挝新记录:版纳拟蚁甲Labomimus bannaus、千兆拟毛蚁甲Paralasinus gigas、海南长角蚁甲Pselaphodes hainanensis、缩长角蚁甲Pselaphodes incisus、拟突长角蚁甲Pselaphodes paraculeus、马格努斯台湾长角蚁甲Taiwanophodes magnus;泰国新记录:版纳拟蚁甲Labomimus bannaus、缩长角蚁甲Pselaphodes incisus、素贴山长角蚁甲Pselaphodes suthepensis;越南新记录:版纳拟蚁甲Labomimus bannaus、茂兰拟蚁甲Labomimus maolan、史氏拟蚁甲Labomimus shii、幸运安蚁甲Linan fortunatus、林氏长角蚁甲Pselaphodes linae。二.具体描述了上述21个新种,且新物种配有相对应的整体图和细节特征图;新纪录种给出了其研究历史、采集措施和分布区域。分析讨论了各物种与其属内相似种之间区分的关键证据。三.统计并编制了长角蚁甲属团的世界名录。四.讨论长角蚁甲属团的世界地理分布特点。更多还原

【Abstract】 Members of the Pselaphodes complex of genera(Coleoptera: Staphylinidae:Pselaphinae: Tyrini)very similar in appearance,small in size,and belong to predatory insects.The complex includes 9 similar genera: Pselaphodes,Labomimus,Linan,Lasinus,Paralasinus,Nomuraius,Indophodes,Dayao,Taiwanophodes.The complex mostly inhabits the moist deciduous layer and dead wood near the water in the mountains and forests,and the weeds and moss growing on the waterside.Members of the Pselaphodes complex of genera’s prey objects are mainly small soil arthropods such as springworms and worms.This group is more sensitive to changes in temperature and humidity,and can be used as an important indicator for detecting the environment.At the same time,It plays an important role in the food chain and food web of ecosystem.Previously,a total of 171 samples of this complex were found worldwide,and the group of this complex was mainly distributed in the Oriental Region and a few were recorded in the Paleobei region.Before this study,the complex was in the southeastern peninsula,India and many other regions lacked investigation and research.The research conducted an accurate and systematic classification,sorting and summary of the specimens through the inspection of about 500 foreign collection specimens collected from the Southeast Peninsula and other regions,using the traditional method of morphological classification,the conclusion is as follows:1.Thirty-seven species of this complex are recognized,of which 22 species in Pselaphodes genus,12 species in Labomimus genus,1 species in Paralasinus genus,and 1 species in Taiwanophodes genus,1 species in Linan genus.Twenty-one new species are found.They are: Labomimus cavicornis sp.n(Vietnam,Thailand),Labomimus cucphuong sp.n(Vietnam),Labomimis huaykonatus sp.n(Thailand),Labomimus palaniensis sp.n(India),Labomimis riedeli sp.n(Java),Labomimus Srilankensis sp.n(Sri Lanka),Labomimis sumatranus sp.n(Indonesia),Pselaphodes banphabat sp.n(Laos),Pselaphodes bukitlarutus sp.n(Malaysia),Pselaphodes dalatensis sp.n(Laos),Pselaphodes darjeeling sp.n(India),Pselaphodes gejiuensis sp.n(China),Pselaphodes jendeki sp.n(Vietnam),Pselaphodes kaligandaki sp.n(Nepal),Pselaphodes khasiensis sp.n(India),Pselaphodes laminatus sp.n(China),Pselaphodes nongfa sp.n(Laos),Pselaphodes olexai sp.n(Vietnam),Pselaphodes parapectinatus sp.n(Vietnam),Pselaphodes retunus sp.n(India),Pselaphodes xiaobailongensis sp.n(China);In addition,there are 16 new records: new records in Shaanxi are Labomimus sichuanicus,Pselaphodes aculeus,Pselaphodes nomurai;new records in Nepal is Pselaphodes spinosus;new records in India is Labomimus medogensis;new records in Laos are Labomimus bannaus,Paralasinus gigas,Pselaphodes hainanensis,Pselaphodes incisus,Pselaphodes paraculeus,Taiwanophodes magnus;new records in Thailand are Labomimus bannaus,Pselaphodes incisus,Pselaphodes suthepensis;new records in Vietnam are Labomimus bannaus,Labomimus maolan,Labomimus shii,Linan fortunatus,Pselaphodes linae.2.The 21 new species included in the above are described in detail,and the new species are equipped with corresponding overall and detailed maps;the new record species gives its research history,collection methods and distribution areas,and analyzed the key points of distinguishing between each species and its similar species in the genera.3.Statistic and compile the world list of Pselaphodes complex of genera.4.Analyze the world geographical distribution characteristics of Pselaphodes complex of genera.更多还原
