The Chonaphini 133 



Color in life — Metaterga black, without spots and usually without 

 stripes, paranota white, cream-colored, yellow, or light reddish orange; 

 collum without a stripe along anterior margin. 



Male syntype — Length 23.3 mm, maximum width 4.3 mm, W/L 

 ratio 18.5%, D/W ratio 65.1%. Body parallel sided for most of length, 

 tapering at both ends. 



Head capsule smooth, polished; epicranial suture shallow, indistinct, 

 terminating above interantennal region. Width across genal apices 2.3 

 mm, interantennal isthmus 0.8 mm. Antennae appearing relatively 

 short and broad, reaching back to caudal margin of 3rd tergite; relative 

 lengths of antennomeres 2>3>6>4=5>1>7. Genae with moderately dis- 

 tinct central impressions, ends broadly rounded and extending slightly 

 beyond adjacent cranial margins. Facial setae as follows: epicranial 

 1-1, interantennal absent, frontal 1-1, genal 3-3, clypeal about 8-8, 

 labral about 12-12. 



Collum broad, ends terminating at same level as those of adjacent 

 tergite. Paranota well developed throughout body, broadest on segments 

 1-6, angling ventrolaterad but interrupting slope of dorsum, anterior 

 corners rounded, caudolateral corners squared on segments 2-5, slightly 

 acuminate on 6-8 and 11, blunt on 9-10 and 12-13, angling caudad 

 on 14-17. Peritremata distinct, strongly elevated above paranotal surface; 

 ozopores located caudal to midlength, opening sublaterad. 



Sides of metazonites generally smooth, polished, with variable 

 curved, shallow impressions. Pregonopodal sterna glabrous; 4th sternum 

 unmodified; 5th sternum with two low, rounded, widely separated 

 elevations between anterior (4th) legs and concave depression between 

 5th legs to accommodate apices of telopodites. Prefemora of legs on 

 segments 11-18 with short but distinct, ventrodistal spines. 



Gonopodal aperture extending caudad between 9th legs, 1.8-mm 

 wide and 1.0-mm long at midpoint, without indentations, sides elevating 

 into broadly rounded, caudolateral lobes, lower in midline. Gonopods 

 in situ (Fig. 2, not this specimen) with telopodites situated in opposite 

 sides of aperture, well separated from each other, extending anteriad 

 in parallel arrangement over coxae of legs 6-7 (on segment 6), termi- 

 nating over 5th legs and sternum of segment 5. Gonopod structure as 

 follows (Figs. 3-7): Coxae of normal size and appearance, with linear 

 fields of 4-6 macrosetae, well segregated by broad sternum, latter 

 with moderate-size lateral lobes. Prefemur moderately long, with large 

 prefemoral process arising from anteromedial surface, latter narrow 

 basally and leaning slightly laterad, expanding at 1/3 length into ledge 

 or shelf on dorsal side, outer margin extending beyond surface of 

 ledge as translucent shield, stem of prefemoral process continuing distad
