Taxon classification Animalia Hygrophila Lymnaeidae

subulatus Dunker in Kuester, 1862 Fig. 46

Limnaeus subulatus Küster 1862: 24, pl. 4, fig. 24.

Limnaeus subulatus Clessin 1886: 395, pl. 16, figs 1, 2.

Type material.

11 shells from the type locality in three samples: no. 4613 and two without numbers. One of these shells (see fig. 45) is separated and marked as belonging to the type collection (a syntype). The rest of specimens are not formally labeled as syntypes but probably also origin from the type series.

Type locality.

Mexico, in Zimapan and Lake of Mexico ( Küster 1862). leg. Albers, Dunker.

Current taxonomic allocation.

Ladislavella (Walterlymnaea) elodes (Say, 1821).

Syntype dimensions.

WN 7.75; SH 32.2; SW 9.6; SpH 22.1; BWH 18.3; AH 11.8; SW 6.6.

Remarks.

Not discussed by Kilias (1961, 1967). Hubendick (1951) considered it to be a synonym of Stagnicola palustris that is apparently wrong since the latter species does not live in North America (Burch 1989; Johnson et al. 2013). Baker (1911) synonymized Limnaeus subulatus with Stagnicola attenuata (Say, 1829) that seems to be more reliable. Currently, Stagnicola attenuata is treated as identical with Stagnicola elodes (Say, 1821), placed by Vinarski (2012) into the subgenus Walterlymnaea Starobogatov & Budnikova, 1976 of the genus Ladislavella B. Dybowski, 1913.
