distinct central impressions. Facial setae as follows: epicranial 2-2, 

 interantennal and subantennal not detected and presumed absent, frontal 

 1-1, genal 2-2, clypeal about 12-12, labral about 20-20. 



Caudolateral corners of paranota angular on segments 2-3, blunt 

 on 4-8, rounded on remaining tergites, becoming progressively angled 

 caudad in caudal half of body. 



Sides of metazonites with irregularly serrate ridges subtending 

 coxae through segment 7, becoming progressively indistinct thereafter. 

 5th sternum with very low, indistinct lobes between 4th legs, flat and 

 unmodified between 5th; 6th sternum with two distinct, widely separated 

 subtriangular lobes subtending anterior (6th) coxae, depressed centrally 

 to accommodate telopodites. Prefemoral spines present on legs on 

 segments 11-18, short and indistinct. 



Gonopodal aperture broadly rounded, without indentations, 1.2- 

 mm wide and 0.9-mm long at midpoint, anterior margin flush with 

 metazonal surface, sides elevating strongly caudad and continuing 

 onto caudal margin, latter flared slightly and extending slightly caudad 

 in midline. Gonopods in situ (Fig. 59, of paratype) with acropodites 

 leaning laterad then curving broadly anteromediad, tips nearly overlapping, 

 extending well beyond anterior margin of aperture and over 6th sternum. 

 Gonopod structure as follows (Figs. 60-61): Coxae moderate-size, connected 

 by membrane only, with 2 macrosetae above cannula, dense cluster of 

 innumerable setae below cannula, and 4-5 setae above latter cluster. 

 Prefemur moderately long and broad, with short prefemoral process 

 arising anteriad, latter narrow basally, extending distad a short distance, 

 then expanding to shallowly divided tip, medial side longer and more 

 acute. Acropodite arising imperceptibly from prefemur, without con- 

 striction, long and narrowly blade-like for most of length, becoming 

 subacicular distad, in form of very broad, open arch, gently curved at 

 highest point, curving broadly anteriad basally and continuing at 

 essentially same curvature to just before tip, where it bends suddenly 

 in uncinate fashion, narrowing thereafter to subacuminate tip. Pro- 

 static groove arising in pit in prefemur, running along medial side of 

 latter and curving onto lateral side of acropodite, angling back onto 

 medial surface at level of base of uncinate curve and continuing to 

 terminal opening. 



Male paratypes — The male paratypes agree closely with the 

 holotype except for the prefemoral process, which is slightly different 

 on nearly every individual. Its length and the apical division vary, as 

 the terminations are more unequal than in the holotype. In one paratype.
