( Figs 3 E-H; 4 D; 11 E) TYPE MATERIAL. — Holotype ( MNHN IM-2000-27733 ) , one paratype ( MNHN IM-2000-27734 ), one paratype (coll. DL) East of Fajou Island , in 80-90 m deep, one paratype (coll. BG ), East of Fajou Island, in 80-90 m deep. TYPE LOCALITY. — East of Fajou Island , Guadeloupe , in 80-90 m deep. ETYMOLOGY. — From Fajou Island, Guadeloupe . DESCRIPTION OF THE HOLOTYPE Protoconch of 1.25 whorls. Teleoconch biconic, H 7.5 mm , D 3.8 mm . Spire high, of four whorls. Last whorl rounded, of 70% of the total length of teleoconch. Apical angle of 55°. Spiral sculpture displaying marked primary cords. Since the second whorl: appearance of P1 and P2. Last whorl: on the sutural ramp, IP; on the convex part of the whorl P1, P2, P3, P4 and P5 well developed; on the siphonal canal, P6 smaller than the other primary cords, ADP, MP and ABP.Axial sculpture:six varices from the first to the last whorl. No intervarical rib. Aperture ovate. Columellar lip smooth, slightly erected anteriorly. Outer lip erected and lacking internal denticles. Siphonal canal open, dorsally recurved and of 25% of the total length of teleoconch. Microstructure: fine spiral threads on the whole surface of the shell. Rough intritacalx drawing the spiral sculpture. Shell color light brown under a creamy intritacalx. Yellow aperture. Operculum with apical nucleus. Radula unknown. COMPARISON (SEE ALSO TABLE 1 ) Dermomurex ( T. ) fajouensis n. sp. and Dermomurex ( T. ) abyssicola are two sympatric species, but they live at different depth (respectively 80-90 m deep and 0.5-20 m deep). Dermomurex ( T. ) fajouensis n. sp. displays a rough intritacalx layer drawing the spiral sculpture, whereas it corresponds to fine spiral threads in D. ( T. ) abyssicola . D. ( T. ) pruvosti n. sp. differs by an atrophied P3, a cancellate intritacalx (instead rough in D. ( T. ) fajouensis n. sp. ) and by four varices on the last whorl with five intervarical ribs intercalated between two varices (instead six varices and no intervarical rib in D. ( T. ) fajouensis n. sp. ). Dermomurex ( T. ) boucheti n. sp. differs by its intritacalx marked by a latticework of axial and spiral lines and by three varices with five intervarical ribs (intercalated between two varices).
