 Chonaphe remissa Chamberlin, 1949:127, figs. 4-5. Chamberlin and 



Hoffman, 1958:27. Kevan, 1983:2968. 



Type specimen — Male holotype (NMNH) collected by W. W. 

 Baker, 2 May 1933, at Puyallup, Pierce County, Washington. 



Diagnosis — Dorsal surface of prefemoral process with broad, 

 thickened, irregular projection distal to shelf; apical margin slanting 

 laterad, lateral side with vertical lamina lying along axis, marginally 

 serrate; shield connecting with inturned lateral margin. 



Color in life — Unknown, but evidence of light paranotal spots 

 on preserved specimens. 



Holotype — Length 24.5 mm, maximum width 5.3 mm, W/L ratio 

 21.6%, D/W ratio 75.5%. 



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

 exceptions: 



Epicranial suture distinct, terminating just above interantennal 

 region. Width across genal apices 3.2 mm, interantennal isthmus 1.1 

 mm. Antennae reaching back to midlength of 4th tergite, relative 

 lengths of antennomeres 2>3>4>5=6>1>7. Genae with distinct central 

 impressions. Facial setae as follows: epicranial 2-2, suprantennal 1-1, 

 interantennal 1-1, subantennal 1-1, frontal 1-1, genal 1-1, clypeal 

 about 11-11, labral about 14-14, merging with clypeal series and con- 

 tinuing for short distance along genal margins, about 3 setae per side. 



Sides of metazonites with low, variable ridges above coxae on 

 pregonopodal segments. 4th sternum with moderately large, medially 

 coalesced projections between 3rd legs, length subequal to widths of 

 adjacent coxae; 5th sternum with two shorter, widely separated pro- 

 jections between 4th legs and slight depression between 5th legs. 

 Prefemora of legs on segments 15-18 with distinct distoventral spines, 

 longest on segments 16-17. 



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

 wide and 0.9-mm long at midpoint, without indentations, sides elevating 

 strongly caudad and continuing onto caudal extension. Gonopods in 

 situ (Fig. 9, not this specimen) extending anteriad from aperture over 

 segment 6 and the caudal part of segment 5. Gonopod structure as 

 follows (Figs. 10-13): Coxae with linear fields of 5-8 macrosetae; 

 sterna with moderate-size lobes subtending coxae. Prefemoral process 

 arising from anteromedial surface, narrow basally, expanding greatly
