Vexillum (Pusia) semicostatum (ANTON, 1838)

Herrmann, Manfred, Stossier, Günter & Salisbury, Richard, 2014, A new subgenus including three new species of the genus Vexillum (Gastropoda: Costellariidae) from the central Indo-Pacific with remarks on Vexillum (Pusia) semicostatum (ANTON, 1838), Contributions to Natural History 24, pp. 1-55 : 27

Vexillum (Pusia) semicostatum (ANTON, 1838)

( Figs 56–58, 60 )

Remarks: Three of four syntypes of this species were deposited in the MTD in the Anton collection. The largest one (MTD 3152/1) was pictured in Turner & Callomon (2001) as lectotype (fig. 10), but no formal designation was made. The other syntypes were not mentioned in that paper. The Costellariidae types in the Anton collection were presented by Schniebs (2003). Three syntypes are mentioned and again the largest one (8.7 mm x 4.8 mm) is pictured. When investigating these syntypes, the authors of the present paper identified the two smaller syntypes MTD 3152/2 (7.4 mm x 3.0 mm, Fig. 58 ) and MTD 3152/3 (5.9 mm x 2.7 mm, Fig. 60 ) as Vexillum (Pusia) tusum ( REEVE, 1845) . To avoid further confusion, we exclude those specimens from the type lot and designate the largest syntype (8.7 mm x 4.8 mm, Fig. 56 ) as lectotype of Vexillum (Pusia) semicostatum (ANTON, 1838) .
