| Notes |
description: A genus of Zenometridae with centrodorsal conical with straight or gently convex sides, H/D about 0.8 to 1.5; rounded or truncated apically. At least basal cirrus sockets separated interradially by narrow flat strip or weak interradial ridge; ridge, when present, no longer than long axis of basalmost cirrus socket. Cirrus socket margins often coarsely crenulate; concave fulcral stereom spreading to lateral margins of sockets. Distal cirrals elongated and tapering; opposing spine weak or absent. Basals broad and tongue-like interradially with a pair of interior openings surrounded by stereom that corresponds to a rosette. Proximal ray ossicles smooth, bearing very fine spinules, or with cluster of small spines restricted to projecting tips of synarthrial tubercles. First segment of P1 with L/W at least 2.0. [details] Taxonomic Remark: All Psathyrometra were originally described in antedonid subfamily Zenometrinae AH Clark, but only three accepted species were transferred to the Zenometridae by Messing & White (2001). The remaining Psathyrometra species not previously transferred to other genera were placed in Athrypsometra [details] | ||||||||||||||||
