 Mesosternum basal width = 2.5 x mesocoxal line length; 



coxal lines straight; base broadly sinuate. Metasternum 



coxal lines meet at middle, recurved; coxal lines extend 



0.33 to 0.5 distance to posterior lateral angle; line behind 



mesocoxa laterally deep, groove-like; sternum feebly 



shining, medial punctures fine, few coarse lateral punctures 



obscured by strong microreticulation . 



First visible abdominal sternite with coxal lines 

 reaching 0.25 distance to posterior edge (Mexico), or barely 

 surpassing coxa (Panama) ; broadly rounded between metacoxae; 

 coarse punctures laterally, fine punctures medially. 



Male genitalia with median lobe weakly arched, apically 

 rounded; internal sac without noticeable sclerotized 

 structures; flagellum straight and narrow, length = 2 x 

 median lobe length (Fig. 115a); base of flagellum straight, 

 sclerite at base elongate claw-shaped (Fig. 115b-d) (3 

 dissected) . 



Female genitalia with spermathecal head elongate 

 kidney-shaped, often with weak top-knot; tail narrow, weakly 

 looped, recurved onto itself (Fig. 115e) (13 dissected). 



Stridulatory files present on occipital region of 

 males' head; absent on females. Male with lateral expansion 

 of prosternum broad, covering most of pronotal epipleuron 

 (Fig. 14). Females with foveate punctures on prosternum in 

 front of procoxae; males lack these punctures. 



Variation . Pronotal spots vary from small and obscure 

 to large and prominent. Central and lateral elytral spots
