D44087E8FFE84354FDD8FB52FD3F9DAC.taxon	description	Description Shell acteonoid, thick, elongated; last whorl with slightly rounded profile; imperforate; D / H ca. 0.5. Spire with slightly rounded whorls and faintly step-like profile; suture distinctly marked. Protoconch indistinct, nucleus fully immersed (Figures 1 (g) and 2 (h )). Teleoconch with ca. 4.5 whorls, entirely sculptured by narrow punctuated spiral grooves; grooves are more numerous in later whorls and more closely packed together towards umbilicus (Figures 1 (c) and 2 (c )). Grooves composed of small rounded-rectangular punctae, partially fused to the next one within each groove; punctae remain individually distinct or more completely fuse with their neighbours (Figures 1 (f) and 2 (g )). Aperture anteriorly rounded, slightly narrowed posteriorly; parietal region with thin well-delimited callus; columellar region broad, slightly expanded, with a sharp edge, bearing a thickened adapical fold; outer lip sharp, thickened externally.	en	Salvador, Rodrigo B., Cunha, Carlo (2020): Lanayrella, a new Acteonidae genus (Gastropoda, Heterobranchia) from Tierra del Fuego.

Protoconch indistinct, nucleus fully immersed (Figure 1 (g )); first whorl width 0.42 mm. Teleoconch with 4.5 whorls, entirely sculptured by narrow punctuated spiral grooves (~ 26 grooves on last whorl), separated from each other by a distance of unsculptured shell of roughly the width of each groove (0.14 mm); grooves become more numerous in later whorls and are more closely packed together towards umbilicus (Figure 1 (c )).

D44087E8FFED435FFE80FE38FC859FF1.taxon	diagnosis	Diagnosis Whorls and spire proportionately shorter than L. vagabunda; shell wall thicker; aperture less elongated. Teleoconch sculptured by less numerous punctate spiral grooves, more widely space than L. vagabunda; punctae rectangular, large and well defined only on first whorls, becoming more elongated and less defined individually on later whorls.	en	Salvador, Rodrigo B., Cunha, Carlo (2020): Lanayrella, a new Acteonidae genus (Gastropoda, Heterobranchia) from Tierra del Fuego.

D44087E8FFED435FFE80FE38FC859FF1.taxon	description	Redescription Shell thick, elongated, last whorl with a slightly rounded profile, imperforate; D / H 0.49. Spire short, with slightly rounded whorls and faintly step-like profile; suture distinctly marked. Colour light brown. Protoconch indistinct, nucleus fully immersed (Figure 2 (h )); first whorl width 0.34 mm. Teleoconch with 4.5 whorls, entirely sculptured by narrow punctuated spiral grooves (~ 20 grooves on last whorl), separated from each other by a distance of unsculptured shell of twice to thrice the width of each groove (0.09 mm); grooves become more numerous in later whorls and more closely packed together towards umbilicus (Figure 2 (c )). Grooves composed initially of small roundedrectangular punctae on first whorls, partially fused to the next one within each groove but still individually distinct (Figure 2 (c )). On later whorls, punctae become narrower and more fused with their neighbours, becoming less distinct individually; the groove takes the appearance of an almost continuous furrow (Figure 2 (g )). Aperture anteriorly rounded, lightly narrowed posteriorly; h / H 0.58; parietal region 0.5 h, with thin welldelimited callus; columellar region broad, slightly expanded, with a sharp edge, bearing a thickened adapical fold; outer lip sharp, thickened externally.
