Pleurocodonellina microperforata Tilbrook, 2006

( Fig. 5A )

Our material accords with Tilbrook’s description of this species from the Solomon Islands in virtually all respects, except that the latero-oral avicularia in the type material tend to have slightly more acute rostral tips. Autozooids in a measured specimen from Singapore are 475‒552 μm long (mean 522 μm) and 218‒331 μm wide (mean 250 μm), compared to the cited means of ~500 μm long and 300 μm wide ( Tilbrook, 2006) .

Fig. 5. A, Pleurocodonellina microperforata Tilbrook, 2006, with one ovicellate zooid and a small avicularium adjacent to each orifice; B‒D, Arthropoma subarensis, new species, at three magnifications; note the four arrowed spine bases in C, with paired spine bases in ovicellate zooids; D shows the reticulate dimpled patterning of the ovicell endooecium, with minute perforations at the bottom of each dimple. Scale bars = 0.5 mm (A, B); 0.2 mm (C); 0. 1 mm (D).
