Myonera paucistriata Dall, 1886

Fig. 41A‒C

Material examined

GALICIA BANK • 4 spm, 16 v; 42°41.87′ N, 11°26.71′ W; 1720 m; 8 Aug. 2011; BANGAL 0711 V10; MNCN .

Remarks

This species was mistaken in the preliminary INDEMARES BANGAL 0711 report ( Gofas et al. 2014b), for the similar M. angularis (Jeffreys, 1876) which has been reported from off Portugal (type locality) and off northwestern Morocco ( Salas 1996: fig. 127) but not in Spain. The latter differs in having only one sharp keel delimiting the smooth posterior area and in having more numerous and finer commarginal ridges on the anterior and median part of the shell. Myonera acutecarinata (Dautzenberg & H. Fischer, 1906) , described from off the Cape Verde Islands, is also very similar but more tapering posteriorly. Myonera bicarinata E.A. Smith, 1896 and Myonera dispar (Dall, Bartsch & Rehder, 1938) have been synonymized by Allen & Morgan (1981) but cautiously retained as separate species by Huber (2010), taking into account their type localities in the Indian Ocean and off Hawaii, respectively.
