摘要
记述了采自海南和浙江省的弹尾目疣科颚毛属CrossodonthinaYosii,2新种,海南颚毛C.hainanasp. nov.和天童颚毛C.tiantongshanasp.nov.。海南颚毛头部每侧有眼2个,弹器痕上有6根刚毛,非常容易与本属其它已知种类分开。天童颚毛与上海产的Crossodonthina tridentiensYue&Yin,1999相似,两者的主要区别是:新种的上颚有两条长的、羽毛状分支和具5齿的片状突起,且基部齿长而细;下颚的内颚叶端部及近基部各有1齿;新种腹部第5节有3+3个疣状突起,而C.tridentiens有2+2个疣状突起;新种的爪部内侧有2个小齿,1个大齿,C.triden tiens只有1大齿。模式标本保存于上海生命科学研究院,植物生理生态所昆虫标本馆。
In the present study, two new species of Collembola, Crossodonthina hainana sp. nov. and Crossodonthina tiantongshana sp. nov. were described respectively from Hainan and Zhejiang Provinces, China. The new species Crossodonthina hainana is easily discriminated from all known species of Crossodonthina by having 2 ＋ 2 eyes and furcular hump with 6 setae. C. tiantongshana is similar to C. tridentiens Yue ＆ Yin, 1999 in some aspects, but differs from the latter in having peculiar mandibles and maxillae.
