External genitalia: Female, last ventral segment long, posterior mar- 

 gin medially produced; pygofers rather robust, spiny, considerably ex- 

 ceeded by the ovipositor. Male, last ventral segment large, concave, 

 and therefore the posterior margin appearing notched; plates long and 

 narrow, each bearing two rows of long bristles, the tips upturned; py-
