Current identification/main database link: Cryptocarpium azyx (Sanfilippo and Riedel 1973)


Original Description
Cephalis within upper part of thoracic wall, and its structure consequently obscure - it is not a small sphere, but a large structure (at least distally) of widely separated, narrow bars forming a loose \basket\". Thorax regularly ellipsoidal, with smooth surface, a somewhat constricted peristome, and thick wall perforated by small, closely spaced, circular pores longitudinally aligned. Peristome narrow, probably with an inwardly directed shelf, terminating in small thorns connected by ridges with the bars between distalmost thoracic pores, and perhaps the remnant of a previously existing abdomen.
QDIn Saunders et al., 1985 (p.412) specimens with abdominal lattice are excluded.

Size: Based on 30 specimens. Total length 105-140 µ, maximum breadth 85-120 µ."

Etymology: The specific name is the Greek azyx (solitary), [and is used as a noun in apposition].
