The present dissertation deals with the taxonomy of cave spiders ( Arachnida, Araneae) from Guangxi, China.

本文对中国广西壮族自治区洞穴蜘蛛（蛛形纲：蜘蛛目）进行了分类学研究。

The energy content of different body regions in Arachnida also exhibited significantly seasonal variations, with the maximal values in autumn ( the mean was 22.98 J/ mg AFDW) and minimal in spring ( the mean was 19.80 J/ mg AFDW).

不同体区含能值同样也表现出季节变动，最高为秋季（平均值22.98J/mg无灰干重），最低为春季（平均值19.80J/mg无灰干重）。

Arachnida and Cecidomyidae had a higher relative abundance than other families being 0.3465 and 0.2309, respectively.
