Hydrachna papilligera K. Viets, 1919

Species incerta

Material examined: Holotype deutonymph SMF 941, Germany, Braunschweig, Teich bei Weddel, 8.7.1910 Kühne.

Discussion: This species was described from a single deutonymph. Later, the author himself proposed its synonymy to H. skorikowi (see K. Viets 1936). In view of the difficulties of associating nymphs to conspecific adults, it must be considered a species incerta.
