& BOUCHET GEN. NOV.

( FIGS 16F–I, 17E, F)

Type species: Mitra millepunctata G. B. Sowerby III, 1889 ; OD, herein.

Diagnosis: Shell small to medium sized (10–45 mm), thin walled, fusiform with rather low spire and high aperture. Protoconch pointed, narrowly conical, of three or more smooth, glossy, slightly convex whorls. Suture distinct, slightly impressed. Spire rather low, orthoconoid; spire whorls with convex outline, sculptured with narrow, rounded, widely set cords. Interspaces between spiral cords bearing finer and lower secondary cords, or fine, widely interspaced, axial grooves. Last adult whorl very high, evenly convex, with shell base extended without clear distinction into straight, stout siphonal canal. Siphonal fasciole not pronounced, siphonal notch shallow or indistinct. Aperture high and moderately wide, its outer lip evenly convex or strongly convex adapically and nearly straight in its mid-width. Inner lip with five fine folds, adapicalmost strongest and succeeding ones gradually diminishing. Shell white, cream or pink, with brown blotches or with regular brown dots or dashes on spiral cords. Radula with narrow rachidian bearing five to eight subequal cusps and wide laterals with narrow base and 15–21 moderately long pointed cusps ( Fig. 17E, F).

Distribution: Indo-Pacific, shallow subtidal to bathyal depths, on sand or mud.

Species included: Roseomitra citharoidea (Dohrn, 1862) 3 comb. nov., R. earlei (Cernohorsky, 1977) 3 comb. nov., R. fluctuosa (Herrmann & Salisbury, 2013) 3 comb. nov., R. honkeri ( Poppe, Tagaro & Salisbury, 2009) 3 comb. nov., R. incarnata (Reeve, 1845) 3 comb. nov., R. millepunctata (G. B. Sowerby III, 1889) 1 comb. nov., R. reticulata (A. Adams, 1853) 3 comb. nov., R. rosacea (Reeve, 1845) 1 comb. nov., R. roseovitta ( Huang, 2011) 3 comb. nov., R. strangei (Angas, 1867) 3 comb. nov., R. tagaroae ( Poppe, 2008) 3 comb. nov.

Etymology: The genus name refers to the pink(ish) colour that characterizes some species, such as R. incarnata or R. rosacea . Gender feminine.

Remarks: As the type specimen of M. millepunctata is lost [ Cernohorsky (1991) noted that the type specimen cannot be traced, and the first author failed to find it in NHMUK as well], we here designate our sequenced specimen IM-2013-40686, measuring 30.0 × 11.4 mm ( Fig. 16F) as neotype of M. millepunctata . This specimen was collected off Noc-nocan Is., Central Philippines, at the type locality of Mitra terryni , a junior synonym ( Herrmann, 2017) of M. millepunctata .

Species of the genus Roseomitra gen. nov. can be recognized by the combination of rather thin-walled shell with proportionally low spire and high aperture, distinctly rounded whorls and Domiporta -like sculpture. The shell proportions with low spire differentiate Roseomitra gen. nov. from closely related Domiporta and most other mitrid genera. Species of Pterygia and Imbricariopsis have a proportionally even higher aperture, but in these genera the shell is conical or ovate, whereas it is fusiform in Roseomitra gen. nov. In turn, Condylomitra tuberosa , C. bernhardina and Quasimitra sophiae have a notably stronger sculpture compared to Roseomitra spp.
