摘　　要：Friesea incognita sp. nov. is described from China. This new species is characterized by the combination of: 2 + 2 eyes, no capitate tenent hairs on tibiotarsi, three anal spines, furcula without mucro and dens with 3 setae. Total dorsal and ventral chaetotaxy of the new species is given. A revised key for identification of the species of this genus with 2 + 2 eyes is given. Forty-seven characters of antennal sensilla, eyes and body chaetotaxy are chosen for the cladistic analysis performed for 18 species of this genus, including 12 with 2+2 eyes. Results indicate the new species F. incognita seems to be related to F. nauimetztli from Mexico. The phylogenetic relationships of the species are not well resolved due to the presence of many homoplasies among different species that adapt to a similar soil habitat.记述河北省奇刺[虫兆]属1新种:迷奇刺[虫兆]Frieseaincognitasp.nov.。迷奇刺[虫兆]的主要特征是头部有2+2眼,足胫跗节无粘毛,腹部末端具3根臀刺,弹器端节退化不见,齿节具有3根刚毛。详尽描述了新种身体背面和腹面的毛序。修订更新奇刺[虫兆]属具有2+2眼种类的检索表。选取触角感器、眼、体表毛序等47个形态特征,对该属18个物种进行了支序分析,包括12种具有2+2眼的物种,结果发现新种F.incognita与墨西哥分布的F.nauimetztli较为相近。由于适应类似的地下生存环境导致许多趋同特征的出现,本研究未能完全解析各物种之间的系统发育关系。
