Measurements for 10 specimens of each population
(GF genital filaments, GP genital pump, a average, SD standard deviation)
Abdomen. Length 1.225. Second sternite with 8–10 bristles on each apical half. Spermatheca, like a pearshaped sac, finely wrinkled transversely, head deeply invaginated in the spermatheca, with pluri-lobed apex (Table 2), fan-shaped (Fig. 2g). Importantly, the head is slightly offset from the axis of the spermatheca, and therefore most often emerges laterally after mounting (Fig. 2g). Common duct and individual ducts not measurable, but a long common duct presence.
