Hydryphantes (s.str.) clypeatus Thor, 1899

Species incerta

Discussion: This species may be characterized by an enlarged frontal shield with very short posterior extensions and a straight posterior margin. The specimens described under this name by Sokolow (1940) and Láska (1964) obviously lie within the variability range described by Lundblad (1962) for H. planus . As the holotype of H. clypeatus is lost and the original description is incomplete, it must be considered a species incerta .
