Family Daesiidae Kraepelin 1899

Members of the family Daesiidae are known from southern Europe, central Asia, the Middle East, Africa, and South America.  The 177 known species are distributed among 29 genera, which are in turn distributed among six subfamilies. The genera Blossia (59 species) and Blossiana (1 species) are placed together in the subfamily Blossiinae.  The genera Biton (66 species), Bitonissus (2 species), Bitonota (1 species), Bitonupa (1 species), and Daesiola (1 species) are placed together in the subfamily Daesiinae.  The genera Eberlanzia (2 species), Gluvia (2 species), Gluviola (1 species), Haarlovina (1 species), and Mumaella (1 species) together make up the subfamily Gluviinae.  The subfamily Gluviopsinae includes Gluviopsida (1 species), Gluviopsilla (1 species), Gluviopsis (11 species), Gluviopsona (3 species).  The genera Gnosippus (4 species), Hemiblossia (16 species), Hemiblossiola (1 species), Tarabulida (2 species) form the subfamily Gnosippinae. The genera Hodeidania (1 species), Triditarsula (1 species), and Triditarsus (2 species) constitute the subfamily Triditarsinae.  Six monotypic genera, including the only two described from South America, are not currently assigned to any of the recognized subfamilies: Ammotrechelis, Ceratobiton, Gluviella, Namibesia, Syndaesia, and Valdesia.  One fossil daesiid is known from Baltic amber.
