A new species of Epichernes (Pseudoscorpiones: Chernetidae) associated with rodents in Costa Rica
ABSTRACT The genus Epichernes Muchmore, 1982 has three Neotropical species with specific rodent hosts. Epichernes vickeryae sp. nov. is here described from Monteverde, Puntarenas, Costa Rica: the specimens were collected from a spiny pocket mouse Heteromys nubicolens. The new species, named E. vickeryae, is closer to E. navarroi by the position of trichobothria setae ist and isb, which are adjacent and the number of teeth on the movable finger, known from Mexico. The new species is characterized by trichobothrium ist adjacent to isb, femur L/B 1.71–1.85, it has 22–31 external accessory teeth, 58 teeth on fixed finger and 62 on movable finger. The carapace ranging from 1.12 mm to 1.33 mm in length, central tergites with 21–22 setae, chelicera with five setae on the hand, sb and b denticulate. The new species represents the second known species of Epichernes from Costa Rica.
期刊介绍：
There is still a far from complete understanding of the complex ecosystems in the Neotropics, although they have been studied since the first expeditions of the old world naturalists Marcgrave, Humboldt, Spix, Darwin, Bates and Müller. The aims and scope of the Journal are, besides taxonomic and zoogeographic surveys, analyses of animal communities and their relationship with biotic and abiotic environmental conditions. This includes the fauna of both terrestrial and fresh water ecosystems in the Neotropics. Contributions that represent original research and mini-reviews are welcome.
Manuscripts presenting just checklists and new geographic records are not considered for publication.
If manuscripts do not meet the requirements of the journal, the editors reserve the right to reject manuscripts on submission or to ask for revisions prior to formal peer review.
