The Chonaphini 129 



Terga smooth, polished. Collum relatively broad, ends terminating 

 above or at same level as those of following tergite. Paranota moderate- 

 size to well developed, broadest on segments 1-5/6, moderately declined, 

 angling ventrolaterad and interrupting or continuing slope of dorsum, 

 anterior corners rounded throughout or blunt on segments 2-3, 

 caudolateral corners variable, either blunt or with suggestion of tooth 

 on anteriormost segments and round on remaining tergites, or squared 

 on anteriormost segments, becoming blunt in midbody region and 

 blunt caudal to midlength. Peritremata broad, distinct to moderately 

 distinct, moderately to strongly elevated above paranotal surface; ozopores 

 located caudal to midlength, opening laterad to sublaterad. Caudal 

 segments normal for family. 



Sides of metazonites variable, with or without variable grooves, 

 impressions, or ridges above pregonopodal coxae. Strictures distinct. 

 Gonapophyses moderately long and stout. Pregonopodal sterna glabrous; 

 4th unmodified or with variable lobes, medially coalesced or widely 

 segregated; 5th sternum with flattened ridges or low, widely segregated 

 projections between anterior (4th) legs and depression between 5th 

 legs; 6th sternum with strong depression between both legs to accom- 

 modate stems of telopodites, 7th legs set slightly farther apart than 

 6th. Postgonopodal sterna glabrous, with broad, shallow, central im- 

 pressions but otherwise without modifications, caudal margins smooth, 

 gently curved. Coxae without projections; prefemora either without 

 ventrodistal spines or with variably short spines on legs in caudal half 

 of body; tarsal claws gently curved. Hypoproct broadly rounded, para- 

 procts with margins strongly thickened. 



Gonopodal aperture generally ovoid, either extending caudad 

 between 9th legs or terminating anterior to latter, with or without 

 slight anteriolateral indentations, anterior margin and anterior halves 

 of sides flush with metazonal surface, latter elevating caudad and 

 continuing onto caudal margin, either descending in midline or con- 

 tinuing at level elevation. Gonopods in situ with telopodites extending 

 anteriad from aperture and lying parallel to each other, overhanging 

 6th and caudal half of 5th sterna. Coxae variable in size, either with 

 2, or linear field of 4-8, macrosetae, well separated from each other 

 by narrow sternal band, latter with short to moderate lobes subtending 

 coxae. Telopodal elements not parallel, arising proximad on prefemur; 

 latter moderately long and slender; prefemoral process large, arising 

 from anteromedial or anterior margins, narrow basally, expanding great- 

 ly at 1/3 to 1/4 length into ledge or shelf on dorsal side, outer margin 

 extending beyond latter to form translucent shield, stem of prefemoral 

 process continuing distad with variably irregular margins, either with
