VELERONINOIDES Saidova, 1981

 

 

Type species: Haplophragmoides veleronis Cushman and McCulloch, 1939 (*830), p. 82; OD.

Veleroninoides Saidova, 1981 (*2696), p. 17.

Test planispiral, evolute, biumbilicate, with numerous low chambers in about two and a half whorls, increasing very little in size as added, periphery broadly rounded, margins slightly lobulate, with chambers much wider than high as seen from the periphery; later sutures slightly depressed, nearly radial; wall finely agglutinated, surface smoothly finished; aperture areal, a low oval to elliptical open­ing near the base of the apertural face, bordered by a slight lip. Holocene; E. Pacific, off Guadalupe Island, Mexico, at 150 m.

 

Remarks: The original description of the genus indicated the type species but stated only "test planispiral, evolute." The type species was described from a single locality off Mexico and has not been reported elsewhere. No sections have been illustrated for this genus, hence whether coiling of the earliest whorls is planispiral or streptospiral remains uncer­tain. Veleroninoides differs from Evolutinella and Haplophragmoides in the areal aperture and differs from the latter and Labrospira in the wholly evolute coiling. It differs from all in the very low and slowly enlarging chambers.
