Crucella cavata intermedicava Gorican et al. 2006 (radiolarian)

Protozoa - Spumellaria - Hagiastridae

Original description: Test with relatively small central area and four moderately long rays each with a strong central spine. Rays constant in width or just slightly expanded distally, subrectangular in axial section with upper and lower surfaces planiform. Each ray with one massive spine (usually broken), triradiate in axial section. Rays with small irregularly arranged pore frames, mostly triangular and tetragonal in shape; small nodes at pore frame vertices. Lacuna in central area variable in size, deep with steep sides.

Original remarks: Crucella cavata intermedicava Carter n. ssp. differs from C. cavata cavata Whalen & Carter in possessing slimmer rays with slightly larger, more regularly arranged pore frames, and spines are triradiate rather than circular in axial section. Differs from C. cavata giganticava n. ssp. in having narrower rays, less massive pore frames, and a smaller lacuna.

Etymology: From Latin: intermedius, -a, -um intermediate and cavus, -a, -um caved; adjective.
