Endemic. Tachysphex dimidiatus DE SAUSSURE, 1892 is a junior homonym of Larra dimidiata PANZER, 1809 in the genus Tachysphex , but this species is a synonym of Tachysphex pompiliformis (PANZER, 1805) . Consequently Tachysphex dimidiatus DE SAUSSURE is an available name (ICZN 1999: Article 59.4). Tachysphex dimidiatus var. excisus ARNOLD, 1945 was published as an unavailable name, because ARNOLD (1945) described several subspecies (n.subsp.) in the same paper (ICZN 1999: Article 45.6.4). But this name was adopted by LECLERCQ (1960) as a valid name of a subspecies (ICZN 1999: Article 45.6.4.1).
