description: A species of Psathyrometra with centrodorsal H/D 0.78-1.53 (rarely <0.90); cirrus sockets separated interradially by narrow flat strip with short basal interradial ridge ranging from low but distinct to almost nonexistent. Distal end of oral margin of middle and mid-distal cirrals often extended distally as triangular spine (visible in oral view); penultimate cirral squarish with weak opposing spine. Axil and br2 with concave proximolateral margins, smooth aborally or with very fine spinules. Proximal brachials with moderately or well developed alternating articular tubercles. Distal midaboral margins of middle and distal brachials smooth. [details] Distribution: Pacific Rim from S Japan to Monterey Bay, CA; Gulf of Panama.
