Fairmaire placed the genus in Graciliini Mulsant whilst Aurivillius placed Psathyrissa (=Linopteriduis) in Oemini [= Xystrocerini Blanchard]. The key differential characteristic between the tribes is the ligula being corneous (Xystrocerini) or membranous (Graciliini) I am most probably showing my level of ignorance, but could someone please explain how one sees the difference between a Corneous ligula and a membranous ligula... on another note, Breuning & Villiers 1958 in their re-description of Linopteriduis state: ...Labium membranous, bilobed... Does this imply that the ligula is membranous??? Thanking you for the help. [/quote]    Insert an Image File Check here to include your profile signature.
