( FIGS 38D, E, 39)

Type species: Mitra tuberosa Reeve, 1845 ; OD, herein.

Diagnosis: Shell small (10–25 mm), ovate to almost conical, heavily sculptured, with pointed conical apex. Protoconch pointed, narrowly conical, of about three very slightly convex, smooth whorls. Spire whorls convex; last adult whorl proportionally very high, sculptured with densely set, gemmate spiral cords, one to three adapical cords very strong, forming prominent, spirally elongated rounded tubercles, directed slightly upwards. Siphonal canal very short, with well-developed fasciole, siphonal notch distinct. Aperture elongate, rather narrow, widening anteriorly. Outer apertural lip gently convex or straight, inner lip with four closely set columellar folds. Radula very narrow, monoserial, with rachidian bearing strong, unpaired medial cusp, flanked with two to eight smaller pointed cusps on each side. Proboscis dorso-ventrally flattened.

Distribution: Indo-Pacific, intertidal and upper subtidal depths, mostly on hard substrates.

S p e c i e s i n c l u d e d: C o n d y l o m i t r a b e r n h a r d i n a (Röding, 1798) 1 comb. nov., C. tuberosa (Reeve, 1845) 1 comb. nov.

Etymology: The name Condylomitra combines the Latin word condylus, meaning knob, with the suffix Mitra , in reference to the characteristic shell sculpture of tubercles that is shared by the species in this newly recognized lineage. Gender feminine.

Remarks: Although each on a quite long branch, C. bernhardina and C. tuberosa form a clade in our molecular trees and share features of the shell and radula, and the characteristic sculpture pattern allows a rather easy recognition of this group. Because of their superficial similarity, we initially considered Strigatella lugubris and ‘ Mitra ’ pudica to be possibly related to Condylomitra ; however, the former is closely related to Strigatella coronata in the Strigatella clade, and the latter, although it was not sequenced, is excluded from Condylomitra by its triserial radula.
