Genus Echinolittorina Habe, 1956 Nodilittorina (Echinolittorina) Habe, 1956: 96–99 (type species by original designation Litorina tuberculata Menke, 1828; cited as Echinolittiorina in error, p. 96). Diagnosis: Shell aragonitic; nodulose, granulose, spirally striate or entirely smooth; if smooth or striate then usually with dark axial stripes or axially aligned series of dashes; eroded parietal area may be present, sometimes a small pseudumbilicus; aperture dark with pale spiral band at base (i.e. anterior end) and sometimes another posteriorly. Cephalic tentacles with 2–3 longitudinal black lines, all black, or with broad transverse band at base distal to eye. Operculum paucispiral. Penis with blade-shaped filament (rarely swollen); base usually bifurcate (not so if mamilliform gland absent); usually a single mamilliform gland (sometimes absent, rarely 2); glandular disc of subepithelial glandular tissue usually present; penial vas deferens an open groove or rarely a closed tube. Rod-pieces of paraspermatozoa usually long and straight (rarely small and irregular, or curved). In pallial oviduct egg groove makes a simple loop through albumen gland, straight path through capsule gland and jelly gland; copulatory bursa opens in anterior or posterior position within straight section of pallial oviduct. Spawn a biconvex pelagic capsule with cupola-shaped upper side sculptured by concentric rings, containing single egg; development planktotrophic. Outer marginal radular tooth with flange at inside and usually also at outside of base. Distribution worldwide tropical and warm temperate. (Diagnosis from Reid 2009.) Remarks: For taxonomic history, see Reid (2007). Monographs are available of the eastern Pacific species [Reid 2002a; as ‘ Nodilittorina ’, but Austrolittorina fernandezensis (Rosewater, 1970) and A. araucana (d’Orbigny, 1840) are now excluded (Williams et al . 2003)], Indo-Pacific species (Reid 2007) and western Atlantic species (Reid 2009). : Published as part of Reid, David G., 2011, 2974, pp. 1-65 in Zootaxa 2974 on page 10 : {"references": ["Habe, T.
