Five species of apseudomorph tanaidaceans were distinguished in recent samples from inshore waters off Brunei. Two of
these, Phoxokalliapseudes gobinae and Mendamanus ailurostoma, were known only from Brunei waters, while
Pagurapseudopsis gracilipes was known before only from Vietnam waters. The opportunity is taken to describe the
female cheliped of P. spinipes, highlighting the previously unknown sexual dimorphism. For all three of these species, the
present material represents only the second record. The two further species were new to science, and are described herein.
One is in the apseudid genus Apseudopsis, and characterized by unusual apophyses on the uropod basis, while the other
represents a new parapseudid genus, showing affinities to Pakistanapseudes and Saltipedis.
