摘要

Objective Limnocythere inopinata(Baird,1843)is an ostracod widely distributed in recent non-marine waters and in Quaternary sediments,where it comprises various phenotypes(Yin et al.,1999;Zhang et al.,2015).Based on the nodation patterns,five phenotypes were described in previous publications,namely,the unnoded,the phenotype with one node in the postero-ventral part of the valve,one with two nodes in the antero-ventral and postero-ventral parts of the valve,another with three nodes in the antero-ventral,postero-ventral and postero-dorsal parts of the valve,and the phenotype with one node in the postero-dorsal part of the valve(Yin et al.,1999;Zhai et al.,2010;Zhai and Zhao,2014).The ecological differences between these phenotypes have not been well documented,and their taxonomic relationships are still under debate(Yin et al.,1999;Hou et al.,2007).In this study,we report two novel phenotypes of L.inopinata from lakes in Badain Jaran Desert,western Inner Mongolia,China,with their ecological preferences described.Our discovery provides new data for studying the taxonomy of L.inopinata and the niche differentiations of its various phenotypes.
