Remarks
Conical to ventricosely conical shell, moderately small to medium-sized (maximum shell length
51 mm
), with a carinate and often nodulose shoulder, and a moderate to high, stepped spire. Multispiral protoconch of about 3 whorls (
Fig. 32L
). Radular tooth (
Fig. 32M
) with an indistinct barb and a pointed blade covering about one third of the anterior section, which is much shorter than the posterior section. Shaft fold present. Basal spur is present on top of the slanted base. The morphology of the shell and radular tooth of
C. boholensis
is very similar to that of
Conasprella pagoda
(Kiener, 1847)
. In the phylogenetic analysis (
Fig. 2
), both species form clades which are very close to each other. These two species can be difficult to separate based upon shell morphology. The shell of
C. boholensis
is usually more nodulose at the shoulder and exhibits radial threads on the teleoconch sutural ramp, whereas in
C. pagoda
the radial threads appear crossed by 4–6 major spiral cords.
