Pycnogonids (Arthropoda: Pycnogonida) from Taiwan, with description of three new species

Pycnogonid material collected between August 2000 and August 2003 from Taiwanese waters at depths between 100 and 2620 m is described. The thirty-three specimens represent ten species, and include one hitherto undescribed species of each of the genera Nymphon, Colossendeis and Pycnogonum. There are no previously published records of pycnogonids from Taiwan. Nymphon polyglia sp. nov. has multiple cement gland pores on the femur and first tibia, and tarsus and propodus subequal in length. Colossendeis mycterismos sp. nov. has affinities with C. pipetta, but has a tarsus shorter than the propodus. Pycnogonum cranaobyrsa sp. nov. has a slender tapering proboscis, no auxiliary claws and pointed mid-dorsal trunk tubercles, with a pustulate integument and a rounded ocular tubercle. The cement-gland openings of Heterofragilia hirsuta are described.
