Genus Ardistomis Putzeys, 1846

Ardistomis Putzeys, 1846: 118. Type species: Ardistomis fasciolata Putzeys, 1846 designated by Desmarest (1851: 102). Etymology. From the Greek ardis (point of an arrow) and stoma (mouth), probably alluding to the apex of the glossal sclerite which is membranous and markedly projected forward (" la languette ... se rétrécit de la base à l’apex qui se termine en une longue pointe membraneuse "), one of the main characteristics of adults of this genus according to Putzeys [feminine]. Note. Lorenz (1998: 48) treated Ardistomis as masculine. However, the ending - is in Latin is of variable gender (masculine or feminine) and in such case the Commission (ICZN 1999: Article 30.1.4.2) rules that the name is to be treated as masculine unless its author, when establishing the name treated it as feminine in combination with an adjectival species-group name. Putzeys (1846) treated Ardistomis as feminine and so the name is feminine.
