) are present just above the nerve cord on each side between the ovaries and the pharynx. The number is uncertain because most appear spent and some are barely distinguishable. There are perhaps four discernable on one side and two on the other. Larger ones are ovate, about 50 μm high and 20 μm long (presumably distorted due to longitudinal contraction of the worm). Only one or two possible spent testes are visible in WF09. A narrow sperm duct, <10 μm wide, runs posteriorly on the inner dorsal surface of the ventral nerve cord on each side. In both specimens each sperm duct expands posterior to the pharynx to about 35 μm wide to form a false seminal vesicle containing stored sperm (cyanophylic) (

). The musculature of the penis consists of outer longitudinal fibres, loose central tissue and a dense layer of circular muscle surrounding the ejaculatory duct. In the penis of WF06 the ejaculatory duct is centric throughout the length of the penis. In WF09 the ejaculatory duct is centric for most of the length of the penis, but is eccentric for a short distance in the mid part. The basal half of the ejaculatory duct in both specimens is lined with, and almost occluded by, eosinophylic cells, presumed to be glandular. The distal portion in both specimens contains amorphous eosinophylic material, almost plugging the duct.
