Austrolittorina fernandezensis ( Rosewater, 1970)

? Litorina mauritiana var. gracilior Philippi, 1847: 165 (no locality in text; 3 syntypes BMNH 20020038 plus 20020039; in part; 2 syntypes probably this species, but largest syntype, figured by Philippi, 1847: Litorina pl. 3, fig. 17b, is Echinolittorina ziczac ).

Taxonomic history. For full synonymy, see Reid (2002 a). As discussed above (see Taxonomic History of A. unifasciata ) the name Litorina mauritiana var. gracilior Philippi, 1847 was probably partly based on this species, although this is speculative. To exclude this name from the synonymy of A. fernandezensis , the largest figured syntype (BMNH 20020038), which is undoubtedly a specimen of E. ziczac , is here designated lectotype.

Diagnosis. Shell large; spiral sculpture of fine microstriae; aperture finely lirate; white with broad indistinct blue-grey zone above periphery. Penial filament small, pointed; small mamilliform gland and large glandular disc on base. Pallial oviduct with two consecutive loops of egg groove, in albumen and capsule glands.

Range. Juan Fernández Islands and Desventuradas Islands, southeastern Pacific Ocean.

Remarks. See Remarks on A. unifasciata for distinction from that species.
