New syarinid pseudoscorpions from Ecuador (Pseudoscorpiones, Syarinidae: Ideobisium and Ideoblothrus)

The pseudoscorpion (Arachnida: Pseudoscorpiones) fauna of mainland Ecuador, excluding the Galápagos Islands, is poorly known, with only 41 described species in 9 families. family Syarinidae has a pantropical distribution and presently comprises ca 120 17 valid genera that are found leaf litter subterranean habitats, mostly tropical subtropical climates. Four syarinid have been recorded from including Galápagos, two widespread genera, Ideobisium Ideoblothrus, but field collections suggest these pseudoscorpions common abundant all forest systems across country. Here, we review syarinids Ecuador describe five new genera: kichwa sp. nov.

These seem to narrow distributions therefore restrict ranges previously (Ideobisium crassimanum Balzan, 1892 costaricensis (Beier, 1931)) their countries origin, which Costa Rica Venezuela, respectively.
