FAMÍLIA: AMPHIBULIMIDAE

ESPÉCIE: Plekocheilus plectostylus (L. Pfeiffer, 1848)

Tamanho médio: 35 mm

Ocorrência: Venezuela

Localidade tipo: Venezuela, “Chachopo, Province of Merida, New Granada (Funck)”

Nome original: Bulimus plectostylus L. Pfeiffer, 1848

Sinônimos: Bulimus speciosus L. Pfeiffer, 1854; Plekocheilus (Eurytus) plectostylus (L. Pfeiffer, 1848)

Comentários: Molluscabase 2025 considera Plekocheilus (Plekocheilus) speciosus (L. Pfeiffer, 1855) como sinônimo de Plekocheilus plectostylus, porém Breure & Ablett, 2011 destacam que “o material de ambos os táxons pode ser estudado no NHMUK. Tanto o tamanho da concha como da escultura são marcadamente diferentes. A classificação subgenérica anterior de Plekocheilus speciosus é assim mantida”
