Named by E. S. Carter.
Original description: Test disc-shaped, large and thick, subcircular to slightly scalloped in outline with short spines radiating from the periphery in different planes. Upper and lower surfaces of test with well defined raised central area, width greater than one-half diameter of test. Central area with numerous large, slight- to moderately-raised tubercules (Holotype, pl. ORB12, fig. 1). Outer rim of test covered with fine spongy pore frames; pore frames in central part of central area sometimes larger and well defined (Paratype, pl. ORB12, fig. 2), but pore frames on tubercules always much smaller. Peripheral spines short, irregularly spaced, variable in width, circular in axial section.
Original remarks: This distinctive species was first recognized in theas having a pseudoaulophacid outline similar to Pseudoaulophacus lenticulatus Pessagno, a central thickening, and peripheral spines.
There are pronounced similarities between Pseudogodia deweveri n. sp. and Orbiculiformella lomgonensis Whalen & Carter 1998, both similar in age. The former possesses large porous tubercules on the raised central area, whereas the latter has a depressed central area and raised tubercules around the periphery of the test. Until more is known, O. lomgonensis is still included with the genus Orbiculiformella.
Etymology: Named for Patrick De Wever, Museum National dHistoire Naturelle, Paris, to honour his pioneering contribution to the knowledge of Pliensbachian radiolarians and for his helpful guidance in the authors early studies of the late Early Jurassic of Queen Charlotte Islands.
