Abstract
Abstract Two new calanoid copepods, Pseudocyclops juanibali n. sp. and Pseudocyclops saenzi n. sp. are described from anchialine pools in the Galapagos Islands. Pseudocyclops juanibali n. sp. is similar to P. australis, P. mathewsoni, P. simplex, P. pacificus, and P. latisetosus. A deep cleft on the distal margin of the endopod of the left leg five of males separates these six species from all other Pseudocyclops likely forming a species group. Pseudocyclops juanibali differs from other members of this group in the shape and number of elements on the distal exopodal segment of the left leg five of males. Pseudocyclops saenzi n. sp. is most similar to P. rubrocinctus and P. steinitzi but differs in the presence of a posterior seta on the basis of the leg five of females, a sclerotized seta on the exopod of the maxillule, and several differences in the shape and ornamentation of the leg five of males. A 569-base-pair region of the internal transcribed spacer 1 ribosomal DNA region (ITS-1) was amplified from...
