Material examined. Donggang fishing port, Pingtung County, commercial trawler, 3 Mar 2001, about 200 m, 1 male cl 9.2 mm ( NTOU M02475 View Materials ) .
Diagnosis. Rostrum reaching middle of second segment of antennular peduncle; dorsal margin slightly concave, with 10 teeth; ventral margin bearing 1 tooth subdistally. Carapace with large acuminate rostral basal spine; antennal and hepatic spines absent, anterolateral margin with 3 teeth; cervical groove distinct. Cornea narrower than eyestalk and darkly pigmented. First 2 pairs of pereiopods slender; grooming apparatus of first pereiopod well-developed. Dactyli of fourth and fifth pereiopods uniunguiculate, slender. Pleon smooth, first plenoite divided into 2 sections by distinct transverse carina. Second to fifth pleura armed with minute spines on ventral margins. Sixth pleonite widened posteriorly, with 2 minute spines on posteroventral margin. Telson lance-shaped; with 2 longitudinal dorsal ridges, each with 5 large spines; 2 pairs of basal spinules present. Uropods with lateral margin of endopod unarmed, that of exopod serrated with 6 teeth.
Coloration. Body generally reddish, covered with whitish spots ( Goy 2010b).
Distribution. Indo-West Pacific: Madagascar, Sri-Lanka, Australia, Philippines, Indonesia, Australia, and now Taiwan, at depths from 174– 640 m.
Remarks. The single Taiwanese specimen, though lacking the third pereiopods, fits well with the descriptions of this species provided by de Saint Laurent & Cleva (1981) and Goy (2010b). The genus Engystenopus is now restricted only to E. palmipes ( Goy 2010b) . The present record slightly extends the northern-most distribution of this monotypic genus to Taiwan.
