Acrodactyla degener (Haliday, 1839)

Acrodactyla spp. resemble Schizopyga spp. (see below), but have their clypeus and face separated by a distinct transverse impression.

The metapleuron of A. degener is smooth, the fore and mid femora are simple. The vertical carina on the mesoscutum in front of the notauli are well developed and the lateral lobes of the mesoscutum have isolated hairs (FITTON et al., 1988). Some of our specimens were reared from the small spider Tenuiphantes flavipes (Blackwall, 1854) ( Araneae : Linyphiidae ).

First report for Belgium and the Netherlands.
