Records from literature. Maneval (1935), Oehlke (1983).

Type locality. ”... au Pont-Ravatgers, commune de Sainte-Croix-Vallée-Française, Lozère” ( Maneval 1935).

Notes on type material. The type material consists of the holotype ♀; it is damaged and some parts are lost: some distal antennomeres of the right antenna; left fore leg; right hind leg. The two valvulae 3 of ovipositor are broken and glued on a label.
