9x as long as wide, with a constriction in basal 1/3, surface otherwise smooth, spermathecal
duct densely covered with knob-like processes beyond the division of the common duct into 2 straight branches (Fig.
Duct has no glandular cover but its distal portion is surrounded with a lush rosette of about 50 [micro]m high gland cells attached to spermathecal

1990) and, therefore, the expression of the cell cycle proteins may be linked to the prevention of DNA damage of the spermatozoids and the spermathecal
Epigynal teeth long, slender, arising from slightly anterior to atrium, with contiguous bases and widely separated apices; atrium large, wider than long, situated anteriorly, separated from epigastric furrow by more than its length, with distinct, continuous, arch-shaped anterior margin; copulatory ducts broad, originating anteriorly; spermathecae broad, slightly extended anteriorly, widely separated by about their width; spermathecal
heads arising distally on spermathecae (Figs.
viridans would greatly benefit from the future use of one or more hypervariable molecular markers applied to females, their spermathecal
contents, and broods (e.
pores and unusual setal arrangement in the South African endemic microchaetid earthworms of presumed Gondwanan origin (Oligochaeta: Microchaetidae).
Structurally, the spermathecae, associated ducts, and the ventral receptacle are innervated with muscle fibers surrounding the spermathecal
capsule, indicating that females may regulate sperm location and use (Fritz 2002; Fritz & Turner 2002).
PickardCambridge (1890) is elementary and is not very helpful in comparative taxonomic work, as it lacks information on spermathecal
Proximal end of vagina or entire vagina enlarged to form vaginal bulb joined by spermathecal

stalks, fertilization ducts long and curved (Fig.
