Geographical distribution and bathymetry
Philippines, S Vietnam, NW Australia at depths between 125‒ 300 m. In New Caledonia, Coral Sea and Loyalty Islands at depths between 300 and 500 m. Also present in Fiji at 282‒444 m (Moolenbeek et al. 2008).
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.
