Diagnosis. A Calliostoma species of rather small size, with an elevated, conical spire, up to 6 granular spiral cords (P2, P3; PI; P4; S2, SI), P3 and P1 the strongest, a moderately convex base with up to 15 spiral cords (3-4 innermost of them being stronger and granular), without umbilicus, an orange colour with possible regular white patches covering two or three beads and separated by two or three orange beads on P3 and P4.
Description. Shell rather small for the genus (H up to 11.5 mm, W up to 8.6 mm), much higher than wide, conical in shape; spire elevated, height 1.3x width, 3.8x to 4.3x aperture height, apical angle 55° to 56°; subangulate periphery; anomphalous. Protoconch about 300 µm wide, 1.25 whorls, rounded, without clear terminal varix. Teleoconch up to 8.0 weakly convex to almost flat whorls; early whorls with 3 spiral cords, last whorl with 6 cords.
Suture weakly impressed, not canaliculated. First whorl convex, sculptured by about 20 rather thin, weakly prosocline threads and 2 spiral cords, beads produced by intersection of cords with ribs; P2 and P3 appearing immediately and simultaneously, P3 quickly a bit stronger than P2; distance between threads similar in size to width of threads, distance between P2 and P3 about 1.5x size of cords. PI appearing at the end of first whorl or at the beginning of second whorl; second whorl still convex, beads of cords stronger, P3 stronger than other cords; P4 hard to detect, almost completely hidden by succeeding whorl; axial threads thicker, transforming into ribs, distance between about 1.5x size of them. Third whorl more or less flat; beads of P3 blunt sharp; axial ribs vanishing. On fourth whorl, S2 appearing, thin and P4 emerging, more visible. On fifth whorl, SI appearing, thin; P3 very strong while P2 weakening; S3 absent. On last whorls, SI, P2 and S2 still weak, P3 and PI the strongest with very different beads: beads of PI strong and separate, those of P3 horizontally elongated and close together; P4 peripheral, subgranular, not as strong as PI and P3 but stronger than the other cords; distance between cords about 2x size of cords. Aperture subelliptical. Columella more or less straight, oblique.
Base moderately convex, with about 15 spiral cords, 3 or 4 innermost cords granular, the others weak and hard to make out; distance between cords similar to cords.
Colour of teleoconch orange, with possible regular white patches covering two or three beads and separated by two or three orange beads on P3 and P4; base lighter, pinkish orange; protoconch whitish with the first quarter orange.
Operculum circular, multispiral, corneous, brown.

Fautor chrysoeides n. sp. is rather close to Fautor richeri (B.A. Marshall, 1995) from southern New Caledonia, but this larger species for a similar number of whorls has a S3 that appears the first of the Si, a narrower apical angle (45-55° instead of 55-56°) and a lower H/HA ratio (2.3-3.0 x instead of 3.8-4.3 x).
