Popis

Shell very small, +/- 6 mm. , slender, claviform, with a very tall spire, almost twice the height of the aperture. Protoconch of 1,5 smooth low conical whorls, followed by two whorls with a sharp median carina. Adult spire-whorls with rather distant axial folds overridden by 3-5 narrow spiral cords, the peripheral one and the one below it, rendering the axials subspinose. Base with more numerous spiral cords but with the axials obsolete. Aperture narrow, terminated in a short unnotched slightly recurved, spout-like anterior canal. Outer lip thickened but not variced. Sinus subsutural, deep, U-shaped, very constricted at its entrance by a massive upper parietal callus. Colour uniform light reddish-brown.
Source: Powell, 1966
Shell tiny (5-7 mm), narrowly claviform with high spire, narrow aperture and short, truncate base, siphonal canal spout-like, not notched terminally, parietal nodule large, greatly constricting anal sinus, which is deep, asymmetrically U-shaped, and directed somewhat abapically, with its apex situated high on shoulder slope; labrum preceded by a varicoid swelling; sculptured by axial ribs crossed by strong spiral lirae, subsutural cord thin and weak, entire surface covered by microscopic granules. Protoconch proportionally large, conical of 3,5 whorls, last two whorls with a median keel. Operculum and radula unknown.

This small species seem to be nearest allied to the Hawaiian Carinapex. They have a somewhat different protoconch, with the addition of regular axials and different adult sculpture, of spiral series of massive nodes. The style of aperture, however, is similar in both genera.
