TYPE MATERIAL: MEXICO: San Luis Potosí: Municipio de Aquismón: outside Cueva del Espiritu Santo Mantetzulel, 21°37′36″N 99°03′42″W, 461 m, 13.ii.2010, G. Contreras, J. Cruz, O. Francke, C. Santibañez, and A. Valdez, holotype ♂ (CNAN T1294).

DIAGNOSIS: Ambulantactus aquismon , sp. nov., may be distinguished from other species of the genus by the male pygidial flagellum, which is deltoid with an acute posterior margin, and a pair of posterodorsal depressions fused posteriorly into a triangular shape. Ambulantactus aquismon is closely related and morphologically similar to A. montielae , sp. nov., but the male pygidial flagellum is more elongated and less bulbous than in A. montielae . Additionally, A. aquismon is smaller (3.6 mm) than A. montielae (4.7 mm); the apical process of the male pedipalp trochanter is obtuse in A. aquismon but acute in A. montielae ; and the pedipalp patella bears four Pe setae in A. aquismon and five in A. montielae .

ETYMOLOGY: The specific name is a noun in apposition taken from the name of the municipality in which the type locality is situated.

DESCRIPTION: The following description is based on the holotype male (fig. 15A).
