在调查台湾南部（垦丁国家公园）的白蚁相关线虫时，发现两种Poikilolaimus，Poikilolaimus cf. floraerensis和一个未描述的种，分离自木白蚁科的白蚁。未描述的物种在形态学上被观察，描述并在本文中以P. carsiops n.新种的特点是一个不寻常的十字形气孔开口形成的两个发育良好的背侧和两个亚腹面唇部门，每个三角形皮瓣和两个退化的侧唇部门缺乏皮瓣，和其他几个形态特征。根据形态学和分子系统发育分析，将其分为三个类群：（P. carsiopsn.）sp.最接近于P. florescensis; i.例如，这两个物种的雄性和雌性都具有相似的规则角质层和短尾，并且缺乏后气孔齿或小齿。在分子系统发育分析中，拟鲤P. carsiops n. sp.和P. floraensis形成了一个支持良好的分支，这是明确分开，但单系，一个分支，包括其他Poikilolaimus物种。因为P. carsiops n. sp.和P. floraculensis仅从kalotermitid白蚁中分离到，P. floraculensis/P. carsiops n. sp. clade被认为是专门与干木和湿木白蚁（Kalotermitidae）。
During a survey of termite-associated nematodes in southern Taiwan (Kenting National Park), two species of Poikilolaimus, Poikilolaimus cf. floridensis and an undescribed species, were isolated from termites in the family Kalotermitidae. The undescribed species is morphologically observed, described and figured herein as P. carsiops n. sp. The new species is characterised by an unusual cross-shaped stomatal opening formed by two well developed dorsal and two subventral lip sectors, each with a triangular flap and two vestigial lateral lip sectors lacking a flap, and several other morphological characters. Based upon morphology and molecular phylogenetic analysis, P. carsiops n. sp. is closest to P. floridensis; i. e., these two species share a plesiomorphic regular cuticle and short tail in both males and females, and a lack of metastegostomatal teeth or denticle. In the molecular phylogenetic analysis, P. carsiops n. sp. and P. floridensis formed a well-supported clade which was clearly separated from, but monophyletic with, a clade that includes the other Poikilolaimus species. Because both P. carsiops n. sp. and P. floridensis have been isolated only from the kalotermitid termites, the P. floridensis/P. carsiops n. sp. clade is considered to be specialised with dry wood and damp wood termites (Kalotermitidae).
