Reported from 155– 274 m.   Description. Shellsmall (to 18.8 mmtotal length), glossy, fusiform, moderately slender with a high spire, whorls up to 11 total, the last approximately 54% of total length;. Whorls convex, periphery below mid-whorl, which appear to sag just above suture; aperture narrow, only a little wider midway than the anterior canal. Protoconchabout 2½ smooth round whorls. Axial sculptureof low broad ribs with round crests, about as wide as their interspaces, widest at whorl periphery, 8–11 on the penultimate and 7 on the body whorl to the varix. Axial growth striae weak; strongest on outer lip. Spiral sculptureabsent except for the presence of 6 fine threads on shell base and 7–9 on anterior fasciole. Sulcusabout ¼-whorl in height, flat, with a few low rib remnants but no other sculpture. Varixhump-like about ⅓-turn from the edge of the outer lip. Outer lipthin, flattened, with 3 strengthening ribs, the larges aligned under the anal sinus; edge folded slightly inward; viewed from its side, edge forms a low arc from, and is congruent with, the anal sinus to the anterior canal, with only a slight dip marking a stromboid notch. Anal sinusdeep, U-shaped and adjoining the suture at its apex; a weak parietal callus at its entrance; inner edge flared. Inner lipunemarginate except anteriorly where it is erect alongside the anterior canal. Anterior canalshort, but well formed, open and only very slightly notched; anterior fasciole not swollen. Colorwhite with 2 light golden-brown bands in rib interspaces above suture line, both visible on the spire whorls; varix with a reddish brown patch.   Remarks. Taxonomy. Splendrillia flavopunctatahas the characteristics of  Splendrillia: a bare sulcus, a reverse ”L”-shaped anal sinus, a hump-like varix, and absence of shell microsculpture except on shell base and anterior fasciole. The two typeswere previously identified on the ANSP data slip as  Cerodrillia carminura(Dall, 1889)but lack the cup-handle varix and spout-like anal sinus of  Cerodrillia.For reasons stated in the section on  C. carminura, the two ANSP lots are not the same as Dall’s original type. Variability.The average total length of six specimens is 15.83 mm( 11.8–18.8 mm), the average W/ L ratio0.354.  Identification. Splendrillia flavopunctatais similar to  S. interpunctata(E.A. Smith, 1882),  S. panamensis, new species,  S. abdita, new species, and  S. bahamasensis, new species. It is similar in size to  S. interpunctatabut differs in having a slightly narrower shell (W/L=0.357 versus 0.429, respectively), less angular whorls, and different coloration. It is similar in size to  S. panamensisbut its shell is also narrower (W/L=0.357 versus 0.413, respectively), and has less convex whorls. From  S. abditait differs in being larger (15.83 versus 9.67 mmin average total length) and in possessing more convex whorls and a different color pattern. It is similar in size to  S. bahamasensisbut its shell is also narrower (W/ L = 0.365 versus 0.413, respectively), lacks the heavy growth striae of that species, and has a different color pattern.   Etymology.The Gold-spotted  Splendrillia. Derived from Latin flavus, gold colored, and punctatuspunctuated. The name was inspired from the two rows of light golden-brown spots between the ribs.
