Abstract

Three new species of Myzomolgus are described as associates of sipunculans from a tidal flat in Phuket, Thailand. As diagnostic features, Myzomolgus leptocercosus n. sp. has elongate caudal rami which are 10.7 times longer than wide, 5 setae and a conical process on the first antennular segment, an armature formula 1, 0, 1+sucker, and 6 of antenna, and an inner coxal seta on all swimming legs. Myzomolgus spatulatus n. sp. lacks a rostrum, but bears 4 setae and a spatulate process on the first antennular segment, an armature formula 0, 0, 2+sucker, and 6 of the antenna, the inner coxal seta on legs 1-3, and 5 armture elements on the third endopodal segment of legs 1-3. Myzomolgus cucullatus n. sp. has short caudal rami which are 1.60 times longer than wide, a broad, hood-like tergite of fouth pedigerous somite, 4 setae only on the first antennular segment, the armature formula 0. 0. 2+sucker, and 6 of the antenna, and no iiner coxal seta on the swimming legs.
