Strophocheilus loxostomus ; Pilsbry 1895 [1895-1896] : 52. Thaumastus (Thaumastus) loxostomus ; Linares and Vera 2012 : 206. Type locality. "in Andibus Novae Granadae". Label. "Andes N. Granada". M.C. label style III. Dimensions. "Long. 71, diam. 34 mill.". Figured specimen H 71.3, D 37.3, W 5.8. Type material. NHMUK 1975125, one syntype (Cuming coll.). Remarks. Pfeiffer did not state on how many specimens his description was based, but said the material was in "Mus. Cuming". The protoconch is sculptured with spaced, indistinct wrinkles, becoming closer towards the transition to the teleoconch. The lip is white, which is quite unusual for Thaumastus s.str. Further research should thus shed more light on the systematic position of this taxon, which is here figured for the first time. Linares and Vera (2012) assumed that this taxon was collected in "Colombia, en una localidad no definida". Although this cannot be excluded, this remains disputable as 'New Granada' had a broader political-administrative meaning at the time the specimen was collected. Therefore, at the moment the allocation of this taxon to the Colombian malacofauna remains doubtful at best. Current systematic position. Megaspiridae , Thaumastus loxostomus (Pfeiffer, 1853).
