Description

SHELL. Closely spaced riblets on last part of protoconch. Teleoconch spotless, with strong, rounded and well-spaced ribs. Very strong and developed lip with columellar lobe quite abruptly inwardly curved to cover umbilicus.

MEASUREMENTS. 8 ♀♀: whorls =6.7–8, H = 6.7–7.7 mm, H/W=2.36–2.64, roundness= 0.11–0.14, ribs incl.= 65–68°, apert. incl.= 15–22°, ribs/mm 1 st wh.= 7–9, ribs/mm 4 th wh.=7–11.

FEMALE GENITAL ORGANS. As in C. (T.) stussineri .

Remarks

Its shell is characterized by a sturdy shape and a very large and thick lip. It is not clear why it was considered a subspecies of C. (T.) gracile : the shell is stumpier and the lip sturdier. The p-distance between the topotypical samples of gracile and reitteri is 2.9%.
