Asteromphalus cleveanus Grunow Fig. 7

ASTEROLAMPRALES Round & Crawford : Asterolampraceae H.L. Smith.

Ref. illus.: Hernández-Becerril 1991, pl. 12, fig. 3

Samples: GU52N-4

Dimensions: Length 42 µm, width 33 µm, areolae 16 in 10 µm in the middle of the segment.

Diagnostics: One singular ray reaching the center, 9 ordinary rays around it (i.e., 10 segments), the segments attached to the central area by long costae; small areolae.

Comments: Record based on one broken LM view found in a turf sample from farmer fish territory but presumably redeposited from the plankton. The shape of the valve and the number of rays distinguishes this species from A. flabellatus (Brébisson) Greville ( Hustedt 1927 –1930, fig. 279; Hernández-Becerril 1991, pl. 12, figs 1, 2).
