Lepidophthalmus sinuensis new species. Mouthparts (internal view): (a) mandible; (b) maxillule; (c) maxilla; (d) first maxilliped; 

 (e) second maxilliped; (f) third maxilliped (exopod not shown). Male CL 11.5mm. Scales equal 2mm (a-e) and 3mm (f). 



slender, curved spine on lateroproximal angle. Ischium 

 with row of 16-17 small spines on ventrolateral margin. 



Minor cheliped of male reaching to about level of 

 bases of fingers of major cheliped. Fingers gaping when 

 closed; prehensile edges of fingers formed by ridge of 

 small rounded teeth. Dactyl with row of tufts of setae 

 on dorsal and ventrolateral margin. Fixed finger with 

 dense, brush-like setae basally on prehensile edge (Fig. 

 3c). Merus with slender curved spine on lateroproximal 

 angle. Ischium with row of 18 small spines on ven- 

 trolateral margin. 



Minor cheliped of female similar to that of male but 

 somewhat slenderer, lacking brush-like setae on fixed 

 finger. 



Second pair of pereopods chelate, subequal; margins 

 of chela and carpus setose; ventral margin of merus 

 with row of evenly spaced long setae. Third pereopod 

 with dactyl slightly longer than broad, subtriangular. 

 Margins of dactyl and propodus with long setae. Pro- 



podus with ventral margin divided into three unequal 

 lobes (medial one smallest); outer face covered with 

 numerous tufts of short setae. Fourth pereopod sub- 

 chelate; propodus and dactyl with setae, densely setose 

 grooming apparatus on ventral margin of propodus. 

 Fifth pereopod subchelate; propodus and dactyl with 

 setae, densely setose grooming apparatus on suboval 

 area covering most of inner face of propodus. 



Abdominal somites smooth; dorsal surface naked ex- 

 cept for line of dense setae forming sub-semioval near 

 posterolateral angles of each somites 3 and 4 and on 

 midline of somite 5, and line of short setae on postero- 

 lateral angle of somite 6 (Fig. Id). Male first pleopod 

 uniramous, two-segmented (Fig. 4c); distal segment 

 with long setae, terminating in subtriangular tip with 

 small lobe at base on anterior margin; basal segment 

 two times (or more) as long as distal segment. Male 

 second pleopod biramous, with appendix interna on 

 endopod (Fig. 4d). Female first pleopod uniramous,
