【摘要】 <正> 最近,我们在整理恙螨材料中,发现一个新种,报道如下。 鼎湖棒六恙螨,新种Schoengastiella(S.)dinghuensis sp.nov.(图1—6) 鉴别特征 盾板袋形、后缘宽圆弧形,后侧毛至盾板后缘的垂直距离64—75(71)、正模为72微米;中足基节长62微米,与后足跗节等长。本新种与社棒六恙螨S.(S.)confuciana Wang,1964相似,但:(1)感器较宽,38×13微米而不是36×10微米;(2)盾板长与宽之比为1:0.54而非1:0.67,感器基位于前侧毛水平线与后侧毛水平线之间的中部而不是偏后;(3)盾板量度明显偏小;(4)盾板毛较长;(5)后足基节毛数目基本稳定为3根,变异者不足4％;(6)腹毛超过35根,多数标本在40根以上;体毛总数不少于60根(不包括胸毛);(7)眼2对。更多还原
