 Metasternal lines extending onto disc from inside of 



mesocoxa toward posterior angle of metasternum, rarely 



continuous around mesocoxae; variable in length, up to 0.5 



distance to posterior angle; line behind mesocoxae variably 



impressed or grooved, occasionally with pit (Fig. 16). 



Legs with femora slightly swollen, complete margin on 

 inner surface (Fig. 21); tibia straight, almost parallel- 

 sided, slightly widened toward apex; tarsi 

 pseudotetramerous . 



Abdominal coxal lines present, short; rarely continuous 

 around metacoxae. 



Male genitalia with median strut length variable, equal 

 to or larger than median lobe; internal sac can bear patches 

 of spinules; flagellum varying in length and thickness, with 

 sclerotized muscle attachment at base, non-slerotized 

 section at base flexible; lateral lobes of tegmen generally 

 flattened. 



Female genitalia with straps appendant to abdominal 

 segment VIII; abdominal segment IX elastic, length variable; 

 flattened plate-like proctigeral lobe; apical segment of 

 coxite with slender styli (Fig. 18) . Proportions of these 

 stuctures vary little throughout the genus. Spermatheca 

 sclerotized, shape of head and tail variable, occasionally 

 with a top-knot (Fig. 18) . 



Stridulatory files often present at the base of the
