摘要 记述了云南高黎贡山球蛛科灵蛛属2新种:长灵蛛Thymoites elongatus Peng,Yin et Hu,sp.nov.和三刺灵蛛Thymoites trisetaceus Peng,Yin et Griswold,sp.nov.。并提供了详细的描述和分布数据。模式标本保存在湖南师范大学生命科学学院和美国加州科学院。长灵蛛,新种Thymoites elongatus Peng,Yin et Hu,sp.nov.(图1 ~6)正模♂,副模1♀,云南腾冲县界头乡桥头村, 1 652m,2006-05-17 ,尹长民,胡佳芳,杨小华采(保存于湖南师范大学)。副模: 1 ♂,云南腾冲县界头乡大塘村大河岭干脚,1 952m,2006-05-17 ,彭贤锦,王新平,胡鹏采(保存于美国加州科学院) ;1 ♂,云南腾冲县界头乡大塘村大河岭干脚,1 952m,2006-05-17 ,彭贤锦,王新平,胡鹏采(保存于湖南师范大学)。新种雌蛛与Thymoites chikuniiYoshida,1988相似,但是有以下几点不同:新种交媾腔位于生殖板中部,远离生殖沟。而Thymoites chikunii的交媾腔则位于生殖沟附近。交媾管也比后者更长,弯曲缠绕更复杂。新种雄蛛与王氏灵蛛Thymoites wangi Zhu,1998类似。但有以下区别:新种插入器很长,几乎围绕整个生殖球边缘,而王氏灵蛛的插入器则相对较短,位于生殖球的中部。新种的贮精管清晰可见,后者的则不明显。词源:雄蛛触肢器具有长的引导器,故名长灵蛛。地理分布:中国云南。三刺灵蛛,新种Thymoites trisetaceus Peng,Yin et Griswold,sp.nov.(图7 ~12)正模♂,副模1♀,云南腾冲县界头乡大塘村大河岭干脚, 1 952m,2006-05-14 ,彭贤锦,王新平,胡鹏采(保存于湖南师范大学)。副模: 2 ♂♂,云南腾冲县新华乡龙井村山清, 1 880m,2006-05-27 ,尹长民,胡佳芳,杨小华采(保存于美国加州科学院) ; 1 ♂,云南腾冲县上阴乡窜龙村,1 990m,2006-06-04 ,尹长民,胡佳芳,杨小华采(保存于湖南师范大学) ;1 ♂,云南腾冲县猴桥乡找笔塘村, 2 510m,2006-05-29 ,彭贤锦,王新平,胡鹏采(保存于湖南师范大学)。新种雌雄蛛都类似于王氏灵蛛Thymoites wangiZhu,1998 ,但有以下不同: 1)新种的外雌器后端无球状隆起,而王氏灵蛛的外雌器后端有球状隆起;2)新种雌蛛的交媾管呈纵向排列,而王氏灵蛛的则呈横向排列; 3)新种的交媾孔接近生殖沟,而后者的则远离生殖沟; 4)新种雄蛛的插入器很短,起始部位于9点的位置,而王氏灵蛛的插入器长,起始部位于3点的位置; 5)新种的插入器基部较小,生殖球腹面突起较少。词源:新种因前中、侧眼间的突起上有3根刺,故名三刺灵蛛。地理分布:中国云南。 This paper describes two new spedes of the spider genus Thymoites(Armleae, Theridiidae ) from the Gaofigong Mountains, Yunnan Province, China, Thymoites elongatus elongatus Peng, Yin et Hu, sp. nov. and Thymoites trisetaceus Peng, Yin et Griswold, sp. nov. Detailed morphological characters, distribution data, illustrations of the body and genital organs are presented.
