Female: Dorsal and lateral pore and pit seta patterns, from rear of cephalothorax through genital compound somite.
Symbols: dots (three sizes) = pores; larger circles = pits of pit setae; smaller circles = structures of uncertain type observed by light microscopy .
Pattern based on SEM and light microscopical examination.
