A new genus and five new species of pseudoscorpions (Arachnida, Pseudoscorpiones, Withiidae) from Colombia.

The pseudoscorpion family Withiidae is widely distributed around the world, with most of its diversity in tropical areas. Five new species and a new genus from Colombia are described: Cystowithiusflorezi sp. nov. , Parawithiusbromelicola sp. nov. , Oligowithiusachagua sp. nov. , and the genus Paciwithius gen. nov. with two species Paciwithiusvalduparensis sp. nov. and Paciwithiuschimbilacus sp. nov. A reassessment of the subgenus Dolichowithius (Oligowithius) Beier, 1936 allows the elevation to a full generic level, and the transfer of the only known species to Oligowithius , forming the new combination Oligowithiusabnormis (Beier, 1936), comb. nov.
