Description:

Male.

Head & thorax: Typical of the genus.

Abdomen: Terminalia with large gonocoxite in lateral view, increasing in width distally. Gonostylus small, elongate, blade-like, S-shaped, with fringe of setae, between which lies well sclerotised tip of aedeagus.

Notes: This specimen was repeatedly examined (e. g., Hennig 1972; B.R. Stuckenberg pers. comm., 2002), but never recognised as a separate species.After the recovery and redescription of other Nemopalpus ( Wagner 2006) , this species is now easily distinguished from other Baltic amber taxa. Although only visible in lateral view, the terminalia are unique. Gonocoxites of N. hoffeinsi Wagner, 2006 and N. tertiariae Meunier, 1905 are elongate, tube-shaped; those of N. molophilinus Edwards, 1921 are similar in shape, but the gonostylus is bipartite and larger than the gonocoxite.
