Umbellapathes Opresko, 2005

Diagnosis. Corallum monopodial and pinnulate, with long unpinnulated stalk; one or more orders of pinnulated branches developing from lowermost primary pinnules. Unpinnulated stalk usually longer than pinnulated section of stem. Pinnules on upper part of stem and on larger branches in two lateral or anterolateral rows, arranged alternately. Secondary pinnules present or absent. Spines conical and smooth, simple or rarely forked, and up to 0.1 mm tall. Polyps 3–4.5 mm in transverse diameter.

Type species. Umbellapathes helioanthes Opresko, 2005 .

Remarks. Two species are currently assigned to the genus Umbellapathes ; H. helioanthes Opresko, 2005 , and the new species described below. Another species, Bathypathes tenuis Brook, 1889 , might also belong to Umbellapathes ; however, the type material consists of two specimens that are too small and incomplete to provide sufficient information to be certain of such an assignment.
