摘要本文记述了一种名为美丽拟crangonyx elegantulus Hou，sp. n.的地下种。产于中国河南省五龙洞国家森林公园的洞穴中。拟crangonyx elegantulus的特征是雌雄均具，触角II上有盖，尾节III背侧缘无甲，尾足III的柄为外枝的0.30倍，外枝的顶条略短于相邻的刺，尾裂为其长度的0.27。基于28S和COI序列的系统发育分析支持种间的差异。本文编制了拟crangonyx属22种的检索表和分布图。
Abstract A subterranean species of Pseudocrangonyx elegantulus Hou, sp. n. is described from caves of Wulongdong National Forest Park in Henan Province, China. Pseudocrangonyx elegantulus is characterized by both male and female with calceoli on antenna II; urosomite III dorsal margin without armature; uropod III with peduncle 0.30 times as long as outer ramus and terminal article of the outer ramus a little shorter than adjacent spines; telson cleft 0.27 of its length. Phylogenetic analysis based on 28S and COI sequences supported the species distinctness. A key to the genus Pseudocrangonyx with 22 species and a map of their distributions are provided.
