Abstract: Parajasonisis Xu, Watling & Xu, gen. nov. urn:lsid:zoobank.org:act: 83A2D112-FC05-4F0D-9AD6-8A8A89CD0417 Diagnosis. Colony planar and flabellate covered with a thick tegument. Branches emerging from the short nodes, usually pseudo-dichotomously divided tending to form sections with a lyrate pattern, occasionally trichotomous. Polyps tall and cylindrical, well spaced and biserially arranged. Elongated scales to flat rods in tentacle rachis becoming smaller in pinnules with irregular outline. Flat rods/needles longitudinally or obliquely arranged in the upper part of polyp body wall, and flat rods/needles and elongate thick scales usually transversely arranged in the basal part. Sclerites in coenenchyme similar to the basal polyp body wall. Large rods/needles sometimes projecting beyond the tentacles. Small rodlets in the pharynx with blunt or conical lateral projections. Type species. Parajasonisis flabellata Xu, Watling & Xu, sp. nov. Etymology: Composition of the Greek prefix para (similar to) and the generic name Jasonisis, referring to the similarity of the new genus with Jasonisis. Remarks. See below.
