Introduction

Limesta is readily distinguished from other rhytidids in north Queensland by the rugose protoconch sculpture which is comparable to that of the central NSW Protorugosa. However, compared with Protorugosa, Limesta has adult sculpture of regular radial ribs (rugosely radial in the former) and very weakly developed spiral striae.

Diagnosis

Shell medium to large, subglobose to globose with a low to high-domed spire, last whorl flared; protoconch sculptured with a combination of bold, raised irregularly curved radial ribs and very fine spiral striae, upper adult whorl surface sculptured with very strong, regular radial ribs, with few, very weak intersecting spiral striae on body whorl, underside of whorls smooth or with weak microspiral striae; lip simple; umbilicus wide, V-shaped. Shell colour deep reddish-brown (rarely all-yellow), occasionally with a yellow spiral band surrounding the umbilicus.

Introduction

Limesta sheridani is readily distinguished from both Murphitella franklandiensis and M. froggatti by the combination of strong radial sculpture on the teleoconch, rugose protoconch sculpture (smooth in both the latter species) and brown shell. Animals are dark grey to sepia to orange-brown in colour with a white dorsal stripe.
