中国贵州宽阔水自然保护区蚋相初报及三新种描述(双翅目,蚋科)(英文)

首次记载贵州省宽阔水自然保护区蚋科Simuliidae14种,并记述其中3新种,包括遵义蚋Simulium(Simulium)zunyiense sp.nov.和新尖板蚋Simulium(Simulium)neoacontum sp.nov.以及隶属于山蚋亚属Simulium(Montisimulium)的离板山蚋Simulium(Montisimulium)separatum sp.nov.。模式标本存放于贵阳医学院生物学教研室。遵义蚋,新种S.(S.)zunyiense sp.nov.(图1～13)隶属于蚋亚属杂色蚋组variegatum group,与本组已知近缘种主要区别在雄尾结构,如生殖肢端节,生殖腹板和中骨的形状特殊。正模♂,贵州遵义市宽阔水自然保护区(28°12’N,107°18’E;海拔1483m),2010-09-20,修江帆,陈黔采。词源:新种种名源自模式产地。新尖板蚋,新种S.(S.)neoacontum sp.nov.(图14～19)隶属于蚋亚属淡足蚋组malyschevi group,与尖板蚋S.(S.)acontum Clen et al.,近似,但雄虫生殖肢端节,生殖腹板和中骨的形状迥异,此外,其呼吸丝排列方式也有明显差异。正模♂,贵州宽阔水自然保护区让水(28°17’N,107°08’E;海拔682m),2010-08-13,修江帆采。词源:新种种名源自其形态极似尖板蚋S.(S.)acontum,冠以"neo"以示区别。离板山蚋,新种S.(Montisimulium)separatum sp.nov.(图20～28)隶属于山蚋亚属Subgenus Montimulium与绒丝山蚋S.(M.)nemoriragum(Datta,1973)近似,主要区别是雌虫生殖板内缘远离,蛹呼吸丝背对具短茎。此外,幼虫头扇毛和肛鳃次生叶数目也有明显差异。正模♀,贵州宽阔水自然保护区大洞(28°12’N,107°18’E;海拔1483m),2010-08-20,修江帆,陈黔采。词源:新种种名源自其雌虫生殖板内缘分离。
