Annotations to the Palaearctic sawfly genus Pseudarge Gussakovskij, 1935 gen. rev. with a contribution to the genus Arge Schrank, 1802 in the Afrotropical region

Koch, F. & Goergen, G. (2008). Annotations to the Palaearctic sawfly genus Pseudarge Gussakovskij, 1935 gen. rev. with a contribution to the genus Arge Schrank, 1802 in the Afrotropical region (Hymenoptera: Symphyta: Argidae: Arginae). Mitteilungen der Münchner Entomologischen Gesellschaft, Agriculture. Ecosystems and Environment, 98, 43-57.

The genus Pseudarge GUSSAKOVSKIJ, 1935 gen. rev. is removed from synonymy with Alloscenia ENDERLEIN, 1919, and Alloscenia syn. n. is synonymised with Arge SCHRANK, 1802. Alloscenia maculitarsis ENDERLEIN, 1919 syn. n. is synonymised with the Afrotropical Arge massajae (GRIBODO, 1879) and Arge goellnerae sp. n. is described as a new species from the Afrotropical region. This paper provides a key for the six known Palaearctic species of Pseudarge including re-descriptions of one East European and two Central Asian species of the genus. A lectotype for Pseudarge rubicunda GUSSAKOVSKIJ, 1935 is designated. The following new combinations are proposed: Pseudarge sinica (WEI & NIE) comb. n., P. wui (WEI & NIE) comb. n. and P. tricincta (WEN & WEI) comb. n. Drawings of all species are presented together with a current distribution map of all Pseudarge and Afrotropical Arge species. The taxonomic relationships of the species are discussed.
