Pseudoscorpions (Arachnida: Pseudoscorpiones) from the Galapagos Islands (Ecuador)

Pseudoscorpions (Arachnida: Pseudoscorpiones) from the Galapagos Islands (Ecuador). - 25 species in ten families are recorded from 25 islands and islets of the Galapagos archipelago. Ten new species are described and figured: Paraliochthonius galapagensis, P. litoralis, P. pecki, P. rupicola (Chthoniidae); Ideoblothrus emigrans, I. galapagensis (Syarinidae); Serianus elongatus, S. maritimus (Garypinidae); Garypus granosus (Garypidae); Cryptocheiridium confundens (Cheiridiidae). Aphelolpium cayanum Muchmore, 1979 and Withius piger (Simon, 1878) are additions to the fauna of the Galapagos; Ideobisiuni simile (Balzan, 1892), Serianus pusillimus Beier, 1959 and Neocheiridium corticum (Balzan, 1887) are removed from the faunal list of the archipelago. Three new synonymies are proposed: Atemnus insularis Banks, 1902 is a junior subjective synonym of Paratemnoides nidificator (Balzan, 1888); Parachernes d. darwiniensis Beier, 1978 is a junior subjective synonym of Parachernes nigrimanus (Banks, 1902); Parachernes darwiniensis maculosus Beier, 1978 is a junior subjective synonym of Parachernes galapagensis Beier, 1977. Withius piger (Simon, 1878) is recorded for the first time from Bermuda. The new combination Cryptocheiridium insulare (Vitali-di Castri, 1984) is proposed for Cheiridium insulare from Guadeloupe.
