Abstract
A new species, Echiniscus ganczareki sp. nov., is described from a liverwort sample collected in Costa Rica. It is the fifth known species of the Echiniscus bigranulatus group and the only one that has pores on ventral cuticle and on legs. It is also the first bigranulatus group species within which males were observed. We also provide an updated key to the Echiniscus bigranulatus group in this paper.References
