The Chonaphini 143 



Somatic features agreeing with those of C. armata, with following 

 exceptions: 



Epicranial suture faint, becoming more distinct and deeply 

 impressed near termination above interantennal region. Width across 

 genal apices 1.9 mm, interantennal isthmus 0.8 mm. Antennae reaching 

 back to caudal margin of 3rd tergite, relative lengths of antennomeres 

 2>3>4>6>5>1>7. Genae with faint impressions. Facial setae as follows: 

 epicranial 2-2, interantennal 1-1, frontal 1-1, genal 3-3, clypeal about 

 7-7, labral about 11-11. 



Collum moderately broad, ends terminating just above those of 

 succeeding tergite. Paranota moderately developed, broadest on segments 

 1-5, angling ventrolaterad and continuing slope of dorsum, anterior 

 corners blunt on segments 2-3, rounded on remaining tergites, caudo- 

 lateral corners with suggestions of teeth on 2-3, rounded on remaining 

 segments. Peritremata moderately distinct, moderately elevated above 

 paranotal surface; ozopores located near midlength, opening laterad. 



Sides of metazonites smooth, without ridges or impressions. 4th 

 sternum with two minute, widely segregated knobs; 5th sternum with 

 two flattened ridges between 4th legs and moderate depression between 

 5th legs. Prefemor of legs on segments 14-17 with short, ventrodistal 

 spines. 



Gonopodal aperture without caudal extension between 9th legs, 

 1.0-mm wide and 0.5-mm long at midpoint, without indentations, an- 

 terior margin flush with metazonal surface, sides elevating caudad 

 and continuing onto caudal margin. Gonopods in situ (Fig. 15, of 

 paratype) with telopodites extending anteriad from aperture in parallel 

 arrangement, overhanging 6th sternum. Gonopod structure as follows 

 (Figs. 16-19): Coxae relatively small, with two macrosetae, sternum 

 with a short lobe subtending each coxa. Prefemoral process arising 

 from anterior margin, narrow basally and curving slightly bisinuately, 

 expanding at 1/4 length into shelf, outer margin extending beyond 

 shelf as translucent shield, latter angling upward and merging imper- 

 ceptibly with lateral margin of stem, stem without distal projection, 

 with curvilinear ridge angling distolaterad from level of shelf to near 

 lateral margin, outer/lateral margin curving to broadly rounded apex, 

 subterminal edge slightly inturned to subacuminate tip, inner margin 

 broadly indented, apical margin curving downward to narrowly rounded 

 tip. Acropodite arising from caudal edge of prefemur, looping around 

 prefemoral process and curling above shelf, displaced distad, normally 

 curling onto shelf and terminating behind shield.
