Characters. Body length ♂ 6.8-7.0mm, ♀ 7.5-9mm. Light to medium brown dorsally, ventrum lighter, little pattern except underlying muscles or developing adult pigment. Antennal segments 44-46, head capsule width ♂ 0.75-0.81mm, ♀ 0.90-1.02mm. Lacinia triangular, palmate, with longitudinally striate palm surface, broad apical teeth, ventral comb of 10-14 bristles and dorsal comb of 16-18 longer bristles (similar to C. ventura , Figs. 50, 51 View Figs ). Right mandible with apical teeth, molar pad of dense stiff bristles, and inner band of hairs from base of apical teeth to molar pad (similar to C. umpqua , Figs. 47, 48 View Figs ). Pronotum with scattered setae over surface, and as a marginal fringe ( Fig. 1 View Figs ). Mesosternal Y-arms with enclosed subtriangular area about 0.3 times the intercostal width. Hind wingpads shallowly notched along inner margin (like C. inyo and C. umpqua , Figs. 15 View Figs , 20 View Figs ); inside forewingpad length ♂ 0.96mm, ♀ 1.26mm. Femora with scattered surface bristles, and tibia with a silky outer fringe ( Fig. 2 View Figs ). Abdominal segments with long surface hairs ( Figs. 26-29 View Figs ). Sexual dimorphism evident. Male with posterior extension of 10 th tergum, triangular in dorsal view with length 0.52-0.57mm; underlying developing wide-based epiproct visible in pharate individuals ( Fig. 4 View Figs ); 10 th tergum in lateral view subtriangular, nearly straight with slightly upturned tip dorsally ( Fig. 8 View Figs ). Female without posterior extension of 10 th tergum ( Figs. 7 View Figs , 28 View Figs ). Cercal segments 30-32; cercomeres with apical circlet of short and long bristles, longer dorsal and ventral bristle in lateral view, and occasional fine intercalary hair ( Figs. 30-31 View Figs ), not usually visible under 50X light microscopy, and not present in any of the other 4 species studied.
