Type-species : Galissus cyanopterus Dupont, 1840 (monotypy). Panchylissus Waterhouse, 1880 : 294 ; Lane, 1978 : 75 ; Monné, 2005 : 626 (cat.). syn. nov. Type-species : Panchylissus cyaneipennis Waterhouse, 1880 (monotypy). The only difference between Galissus cyanopterus Dupont and Panchylissus cyaneipennis Waterhouse , both typespecies, is the density of hairs in the metatibiae, which are densely piloses in G. cyanopterus and with sparse hairs in G. a z u re u s Monné & Martins, 1981 , P. cyaneipennis and P. nigriventris Lane, 1965 . The density of the pilosity is an insufficient character to consider Galissus as a different genus of Panchylissus and we herein propose the synonymy of Panchylissus with Galissus .
