Material.

Netherlands (Meijendel, dunes near The Hague; Rockanje, wet Salix repens dunes; Oostkapelle, Oranjezon; 't Harde). Mostly collected in August and September, but a few specimens were collected in May and June.

Synonyms.

Elasmosoma viennense Giraud, 1871, syn. n. (examined). According to Shaw (1992) the holotype of Neoneurus clypeatus is a male and has the third and fourth antennal segments shorter and less densely setose and the hind tibial spurs and hind tarsal segments shorter than in the male holotype of Elasmosoma viennense ; the body, hind coxa and the antenna of the holotype of Neoneurus clypeatus are much paler than those of Elasmosoma viennense . Elasmosoma viennense has the tegulae pale yellowish; dark brown or brown, the clypeus yellowish-white, yellowish-brown or brown and dorsally darkened, the hind coxa yellowish; largely black or dark brown. However, the holotype of Neoneurus clypeatus is coloured as a typical female and it may be either just an anomaly or a female. In general, Foerster types are paler by ageing than types from other collections of similar age, including Giraud types and limited weight should be given to colour differences in general.

Notes.

If the scapus and tegulae of a male are pale yellowish or whitish, the hind coxa largely yellowish-brown and the vertex finely granulate, the specimen may represent the unknown male of Neoneurus vesculus or Neoneurus recticalcar , the latter probably has a slenderer fore femur and tibia than the former.
