Description of spermatheca. Spermathecae ( Fig. 2C ) paired; pore located slightly below line of lateral chaetae; duct smooth, 195–225 µm long, about 15 µm wide; ectal gland about 35 µm in diameter; ampulla oval, about 35 µm wide, containing loosely arranged sperm; ampulla followed by duct connecting to spherical ental chamber, about 55 µm wide; ampulla in V or VI, ental chamber of one spermatheca usually occupying VI and the other VII; spermatheca not connected to oesophagus.

Remarks. In the original description, Martinsson et al. (2015b) illustrated a spermatheca that was not fully developed, here we describe and illustrate one that is.
