Synonymy The variety was described by Hentschel from the Aru Islands, Stats. 12–14, approximate coordinates 6.2946–6.2985° S 134.3249–134.7609°E, depth 15–18 m (14 syntype specimens, SMF 1061–1064). Although Hentschel did not indicate any differences of his variety with the the typical variety of Ridley & Dendy (1886: 327, collected in the Eastern Philippines (Challenger Exped. Stat. 208, 11.6167°N 123.5167°E, depth 33 m, holotype BMNH 1887.5.2.208), it may be deduced from the two descriptions that strongyles in the present variety exceed those of the typical variety in length, 192–280 μm vs. 170 μm in Ridley & Dendy’s material, but Hentschel described also smaller strongyles 64–136 μm long, and he admitted that perhaps intermediate sizes between the larger and smaller strongyles were present. Hentschel’s material was extensive, whereas Ridley & Dendy only had one small fragment, which may explain the more limited spicule size they gave. The differences seem insufficient to justify recognizing a separate taxon for the present species and accordingly I propose to merge the variety into a single, somewhat variable species to be named Petrosia (Petrosia) truncata (Ridley & Dendy, 1886).
