[Boxed spermatheca is for comparison of Aporodrilus esculentus (Benham, 1904) from Benham’s fig. 67 and from Lee (1959: fig. 309)].

Figure 2b.Aporodrilus ponga dorsal view of prolobous prostomium, spermathecae (8lhs and 9lhs and part of 9rhs) and prostate in 18lhs in situ. Male field is shown with setae 17b? and 17a marked (setae a occluded by male pores on 18).
