A New Species of Genus Laboulbenia (Laboulbeniales) on Craspedophorus formosanus (Coleoptera, Carabidae) from Taiwan, with a Note on Laboulbenia asiatica

Abstract

Laboulbenia taiwaniana sp. nov. on Craspedophorus formosanus is described from Taiwan and illustrated with photographs. It is characterized by a long, asymmetrical perithecium with an oblique apex and a pale-colored lower wall, a slender, evenly tapered receptacle with cylindrical cell I and II and trapezoidal cell IV, well developed appendages with black septa concentrated in the basal portion of the appendage system, and especially by black septa on the distal end of cell g. Laboulbenia asiatica, which was described from an Asian carabid-"Casnonia sp."-in 1899 and was illustrated in 1908 by Thaxter, is reviewed and compared with L. taiwaniana morphologically.
