Material Examined
2 ♂♂, “SLOVAKIA centr., 1200 m, Polana Biosphere Reserve, Zadná Polana N.N.Res., 6.5.–3.7.2006 Malaise trap, J. Ševčík & J. Roháček leg." [48.66°N, 19.49°E].
Drepanocercus was originally defined on the basis of having the cubital fork very near the base of the wing and elongated female cerci (Vockeroth, 1980). Acomoptera spinistyla shows neither of these features and in its original placement, prevents a clear distinction between Drepanocercus and Acomoptera. The spiky gonostyli of Drepanocercus spinistylus recall similar conditions found in Acomoptera species such as Acomoptera digitata (Fig. 11D) and Acomoptera plexipus (Fig. 23D). Furthermore, in Acomoptera spinistyla and Acomoptera plexipus, there is a bifurcate dorsomedial process (Søli, 1993: fig. 2D, Fig. 23A) and a broad gap before the posterior margin of the hypandrium (Søli, 1993: fig. 2B, Fig. 23B). For these reasons, it seems appropriate that this species be transferred to Acomoptera. Further study is needed to evaluate the position of Drepanocercus ensifer; for now, it remains separated from Acomoptera by its original defining characters.
