Description. — Integument iridescent. Carapace 

 (Fig. 5a, h), exclusive of rostrum approximately 

 as long in midline as broad, sculptured, variably 

 ridged longitudinally; anterior and posterior 

 cervical grooves apparent but obscure, promi- 

 nent transverse ridge across anterior part of 

 raised cardiac region; crowded rugae on dorsal 

 surface moderately elevated, most closely clus- 

 tered and transversely elongated on median 

 prominences, especially on cardiac region, giving 

 an overall uneven, variably pebbled appearance; 

 a nearly smooth and slightly concave spot to 

 either side of midline at anterolateral corner of 

 cardiac region. Rostrum broadly subtriangular, 

 transversely arched, base broader than mid- 

 sagittal length; dorsal surface in lateral view 

 with concave base smoothly curving into up- 

 wardly inclined distal part having almost 

 straight dorsal margin, apparently acute tip 

 slightly blunted by damage; lateral margins 

 anterior to eyes serrate, but concave posterior 



margins adjacent to eyes nearly smooth; scat- 

 tered tubercles on anterior % of length much 

 smaller and more numerous than larger, sym- 

 metrically arranged rugae on posterior %; ante- 

 rior part with noticeable brush of plumose setae, 

 densest ventrally. Sinuous frontal margin with 

 broad angle lateral to eyestalk continued laterad 

 as thin raised edge curving into a small serrate 

 lobe proximolateral to basal article of antenna; 

 anterolateral angle densely and sharply rugose, 

 followed by similar but somewhat more broadly 

 projecting lateral margin of anterior branchial 

 region, margin thinner on posterior branchial 

 region. Posterior margin broadly and shallowly 

 concave, slightly sinuous; preceded in turn by 

 submarginal narrow rugose ridge, and trans- 

 verse narrow smooth tract. Lateral plate project- 

 ing anteriorly below antennal peduncle, its rather 

 angular anterior tip bearing minute spine in line 

 with base of eye; strongly rugose posterior part 

 separated from somewhat less strongly rugose 

 anterior part surrounded by impressed groove 

 running submarginal to anteroventral aspect, 

 then sweeping posterodorsally and recurving
