Current identification/main database link: Lamprocyclas maritalis maritalis Nigrini 1967
Shell campanulate, usually thick-walled, and generally with a rather rough surface. Cephalis elongate, trilocular, the 2 secondary lobes beneath and somewhat lateral to the larger primary lobe (cf. pl. 7, fig. 7). Pores numerous, subcircular; apical horn stout, 3-bladed, 2 or 3 times cephalic length. Primary lateral and dorsal spines continue as ribs in the thoracic wall for about half its length; rarely, these project from the thorax, forming small wings. Collar stricture not pronounced.
Thorax cupola-shaped (conical above, inflated below) with hexagonally framed circular to subcircular pores, arranged in longitudinal rows and increasing slightly in size distally; 9-11 across the widest part of the segment. Lumbar stricture distinct and marked internally by a septal ring. Abdomen cylindrical, inflated. Pores hexagonally framed, circular to subcircular, arranged in longitudinal rows; larger than thoracic pores, 9-10 on a half-equator, 3-5 in a vertical series.
Peristome well differentiated, poreless, sometimes with up to 12 triangular lamellar teeth arising from its lower edge, but often teeth are rudimentary or absent. Subterminal teeth, on the abdomen just above the peristome, are conical or thorn-like, divergent, and usually better developed than terminal teeth.
Total length (excluding apical horn) 119-173µm. Length of cephalis 27-36µm; of thorax 45-63µm; of abdomen (excluding peristome) 45-72µm. Maximum breadth of thorax 81-90µm; of abdomen 100-128µm. Distinguishing characters (rw): Hays (1965) apparently called all specimens of this general form L. maritalis. Two subspecies of this species have been distinguished herein, that is, L. maritalis maritalis and L. maritalis polypora (p.76). Hays' description is probably based on numerous specimens of L. maritalis maritalis and rare specimens of L. maritalis polypora.

Indian Ocean occurrences (fig. 39) .- L. maritalis maritalis is very sparsely distributed in low latitudes, but is fairly abundant (3% to 9% of the described population) south of 35° S (cf. L. maritalis polypora, discussion, p.77).
