摘要
记述了局限蚊属(丽蚊亚属)一新种,丹珠局限蚊Topomyia(Suaymyia)danzhuensis sp.nov。该新种的主要特征是:雄蚊喙具基白环;腹节第IX-T侧叶端部的刺形鬃膨大呈刀型,内缘小鬃列位于端部而非基部;抱肢基节端腹叶具长鬃丛和背内侧中部具短鬃群,抱肢端节外枝明显比内枝粗大;幼虫下颚宽短,端缘具多个小齿突;梳齿数量较少和仅分布于呼吸管基部腹侧和肛腮粗壮及其末端钝圆等。模式标本采自云南省怒江州贡山县高黎贡山东坡竹林。标本保存于云南省地方病防治所。
Topomyia(Suaymyia)danzhuensis sp.nov,from Yunnan province of southern China is described.It is similar to To.(Sua.)yanbarensis Miyagi,1976,To.(Sua.)yanbareroides Dong et Miyagi,1995 and To.(Sua.)bambusaihole Dong,Zhou et Dong,1997.All them has the following diagnostic characters:Scutum with lateral margin pale scale patches extended from scutum angle to anterior basal area of wing.Distimere medially divided into two long branches.Claspette with two strong apical spicules,and larvae maxillary with marginal denticulata numerous.But it could be distincted from the following combination features.1.The broad median-longitudinal stipe on scutum is in white color in the new species,but pale in To.(Sua.)yanbarensis.2.It differs from To.(Sua.)yanbareroides and To.(Sua.)bambusaihole by the following combination features in males:Proboscis with a white base band;The spiny bristles at the end of the IXT lateral lobe expanded into knife shape and the small bristles at the inner edge were arranged at the end rather than at the base;The apical ventral lobe of the basimere has a long bristle cluster and the medial side of the middle back has a short bristle cluster;Outer branch of distimere obviously stronger than the inner one.3.It differs from To.(Sua.)yanbarensis,To.(Sua.)yanbareroides and To.(Sua.)bambusaihole by the combined characteristics of larvae:Seta 5-C is far away from 3,4 and 6-C(instead of 3~6-C juxtaposed at the front edge of the front oclypeus),7-T is developed,divided into 7-8 branches(instead of only 3 branches)and anal gills are thick and blunt at the end(instead of thin,long and sharp),which can be distinguished from To.(Sua.)bambusaihole;besides this,Maxilla broadly short,without apical strong branched spicules,few pectens limited in the ventral base of the siphon could separate it from the first two species[To.(Sua.)yanbarensis,and To.(Sua.)yanbareroides].Etymology Danzhuensis is derived from the collecting place Danzhu mountain area in Gongshan County,Nujiang Prefecture,Yunnan province.Holotype(wing length 3.3 mm),paratype 5,1♀(Average wing length about 3.3 mm);1 larvae specimen,Four separate larval skin specimens.All specimens were collected from bamboo tube water in Danzhu,Cikai and Pengda villages and towns(E 98°30'N 28°00';altitude 1600-1800 m)separately in September 2012 and October 2021.All the specimens are deposited in Yunnan Institute of Endemic Disease Control and Prevention.
