 medially (Fig. 16a); coxal lines extend 0.5 distance to 



posterior lateral angle (Fig. 9a); sternum with medial 



punctures fine, few coarse lateral punctures 3 x larger than 



medial punctures . 



First visible abdominal sternite with coxal lines 

 reaching 0.5 distance to posterior edge; broadly rounded 

 between metacoxae; coarse punctures laterally, fine medial 

 punctures dense. 



Male genitalia with median lobe moderately arched, 

 apically truncate, slightly constricted just before tip; 

 internal sac without noticeable sclerotized structures; 

 flagellum long and narrow, length = 1.9 x median lobe length 

 (Fig. 107a); base of flagellum curved, sclerite at base 

 blunt claw-shaped and thickened at connection with flagellum 

 (Fig. 107b-d) (5 dissected) . 



Female genitalia with spermathecal head kidney-shaped, 

 often with top-knot; tail swollen, tightly curved like an 

 inverted question mark, " i" (Fig. 107e) (13 dissected). 



Stridulatory files on occipital region of head present 

 in males; female specimens had heads retracted, presence 

 unknown. Females with lateral patch of foveate punctures on 

 prosternum in front of procoxae; males have, at most, 5 to 6 

 punctures immediately in front of procoxae. 



Variation . Gorham (1887:40) comments on the 

 differences in head color in this species, solid black or 

 with orange epistome and vertex, and illustrated each form. 

 In all of the specimens examined, the proportion of black
