【摘要】 通过研究同一种群雌性宽肋盘腹蛛Cyclocosmia latusicosta Zhu,Zhang&Zhang,2006,发现该种个体间在体长、步足长度、齿堤齿的形态与数量、圆盘肋数及纳精囊长宽之比等方面变异较大;宽肋盘腹蛛与里氏盘腹蛛Cyclocosmia ricketti(Pocock,1901)的区别主要是圆盘印痕中央是否存在纽扣状突起。更多还原

【Abstract】 Fifty female spiders of Cyclocosmia latusicosta Zhu, Zhang & Zhang, 2006 were collected from a small mountain in Guangxi, China and their morphological variations were studied. The adult female changes in total length (19.2-36.2?mm), leg formula (3214, 2314, or 3241), teeth on chelicera (shape and number), rib counts (18-25), and shape of spermathecae (length/width: 1.34-3.00). The diagnostic characteristics for Cyclocosmia spiders were evaluated.更多还原
