FIGURE 7. Microceratina pseudoamfibola (Barbeito-Gonzàlez, 1971), valve morphology: A: LV-1; B–H—RV-1; I–L—RV-2 (Grotta Sulfurea di Cala Fetente, Tyrrhenian Sea, southern Italy); A—LV, external, general view (white arrow indicates the AMZ); B–H—RV, external; B—general view (light gray arrow indicates the round ridge delineating the postero-ventral protuberance); C—reticulum with solum covered by fossae and an intramural conulus pore, A"-type (dark gray arrow); D, E—details of fossae and loophole pores (LStPC); F—detail of shape of anterior section of valve (white arrow indicates the AMZ); G—detail of central valve area with reticular structure, central muscle imprints and NPC on a conulus, A"-type (dark gray arrow); H—detail of posterior valve shape (black arrow indicates a conulus with an emergent sensillum, A"-type); I–L—RV, internal; I—general view; J—central valve area with reticular structure, four muscle imprints, and apertures of NPC and of LStPC; K, L—details of two NPC which open on the inner side of the valve; black arrow in L indicates the minute diameter of aperture of a LStPC as compared to a NPC.
