Specimens examined

NMBE 515473/1, Nahr al Damour, 33.704°N, 35.452°E, 20 m alt., 18.08.2008; NMBE 515474/1, Qanater al Zbeideh, Nahr Beirut, 33.85°N, 35.556°E, 80 m alt., 19.08.2008.

Diagnosis

shell small, teleoconch whorls with strong axial ribs, granules and long hairs.

Description

shell small, spire slightly elevated; protoconch consists of 1.5 smooth whorls; teleoconch greyish to brownish, with strong axial ribs, whorls covered by a dense sculpture of small granules and very long, soft hairs; hair scars visible even in eroded shells; suture moderately deep; last whorl slightly bending towards the aperture; aperture broadly oval, reinforced by a white lip (discernible from the outside); peristomial rim sharply bounded; umbilicus open, partly covered by a triangular columellar callus.
Measurements (Fig. 11): H = 4.72; D = 8.3; PH = 2.08; PD =4.76.

Distribution

This seems to be a rare species in Lebanon. It has probably been overlooked because of its small size, or even misidentified, because its hairs can easily fall off, and the remaining shell is less characteristic. It is possible that this species is more widespread.

Remarks

This species differs from all Lebanese Monacha species by its haired shell. Even eroded shells can be identified when using higher magnifications to see the axial ribs in combination with the granulated surface and remaining hair scars.
