Abstract

The genus Neoarisemus was proposed by Botoşaneanu & Vaillant (1970) for the extant North American species Psychoda nigra Banks, 1894. The diagnostic characters are eyes without eye suture, wing venation with R5 vein pectinate, wing forks complete and in basal position, epandrial appendages basally swollen, and aedeagus asymmetrical. In his treatise on Palearctic Psychodidae Vaillant (1975: p. 168) transferred to the genus Neoarisemus several species previously placed in genus Telmatoscopus Eaton, 1904, among them N. spinitibialis (Tokunaga & Komyo, 1955) [Japan] and N. lindbergi (Vaillant, 1963) [Afghanistan]. Neoarisemus ibericus Wagner, 1977 [Spain], and N. sardous Wagner & Salamanna, 1984 [Sardinia] were described later.
