Note midventral gap in white pigment ring. B. Dorsal view of live specimen (paratype SIO-BIC A7847) showing white pigmented ring anteriorly with a dorsal gap where oviduct runs through it. Note pinnules of all palps oriented dorsally and oviduct lying between dorsalmost pair of palps. C. Differential interference micrograph of a solitary male dissected from tube of paratype (SIO-BIC A7847). Some hooks are visible in expanded posterior region. A large mass of mature sperm is visible in mid-body and extending into head, though there are a few obvious spermatids. D. Transverse section (7 µm) of paratype (SIO-BIC A7847), through crown showing pinnules of all palps oriented dorsally and oviduct lying between dorsalmost pair of palps. E.
