curvatures of telopodites. Postgonopodal sterna glabrous, flat, and 

 unmodified, with at most only shallow transverse grooves between 

 leg pairs, caudal margins gently curved. Coxae without projections; 

 prefemora of legs on segments 9-18 with ventrodistal spines, longer 

 and more distinct on segments 11-15; tarsal claws gently curved. 

 Hypoproct broadly rounded, slightly extended in midline; paraprocts 

 with margins strongly thicked. 



Gonopodal aperture ovid, without indentations, 1.4-mm wide and 

 0.7-mm long at midpoint, anterior margin flush with metazonal surface, 

 sides elevating caudad and continuing onto caudal margin, latter flared 

 slightly but not extending caudad. Gonopods in situ (Fig. 53b) with 

 acropodites extending forward in parallel arrangement, overhanging 

 anterior margin of aperture, apices curling laterad then mediad. Gonopod 

 structure as follows (Figs. 54-55): Coxae moderate-size, connected 

 by membrane only, without trace of sclerotized sternal remnant; with 

 2 macrosetae above cannula and dense cluster of a dozen or so setae 

 on protuberance below latter. Prefemur moderately long and broad, 

 with short prefemoral process arising near midlength on anterior side, 

 latter extending to just beyond level of tip of acropodite, broadest 

 basally, sides narrowing and tapering to subacuminate tip on lateral 

 margin, directed toward midpoint of arc of acropodite. Latter arising 

 from prefemur at narrow constriction, relatively long, blade-like for 

 most of length, tapering smoothly and continuously, more so distad, 

 to subacuminate tip, in form of broad open arch, flattened at highest 

 point, curving broadly anteriad at 1/3 length and bent more strongly 

 dorsad at 2/3 length, distal part curving in markedly bisinuate fashion. 

 Prostatic groove arising in pit in prefemur, running along medial 

 surface of latter and crossing to lateral side at base of acropodite 

 returning to inner surface at peak of arch and continuing to terminal 

 opening. 



Male Paratypes — In two individuals the acropodites cross in situ 

 at the midline instead of lying parallel, and in one male the prefemoral 

 process is shorter in relation to the acropodite. 



Female paratype — Length 29.0 mm, maximum width 4.5 mm, 

 W/L ratio 15.5%, D/W ratio 82.2%. Agreeing essentially with males 

 excepting the presence of interantennal, subantennal, and frontal setae, 

 1-1 each, and paranota more strongly depressed, imparting more vaulted 

 appearance to body. Cyphopod aperture encircling 2nd legs, sides and 

 caudal margin flush with metazonal surface, elevated only midline. 

 Cyphopods in situ lying transversely in aperture, common surface 

 visible in opening. Valves (Fig. 58) relatively small, unequal, anterior 

 valve larger, situated nearly entirely on top of receptacle, slightly
