Yesterday seen in my garden (Koudekerke, Walcheren, Netherlands)this Ctenophora (Tupilidae). Could anyone help me with the species name? Is it a female?

Jan Zwaaneveld gave me the comments (26-12-2006) of Louis Boumans about a male cranefly with 2 wingspots:
.... only 2 species have a stigmatic + an apical wing spot, i.e. Dictenidia bimaculata and Ctenophora nigriceps. The latter is not known from the NL, only from Sweden, so this must be D. bimaculata, which is also "the most widespread"and "relatively frequently encountered".
I didn't find any photos of a Ctenophora nigriceps to compare but meanwhile Louis Boumans confirmed me that my cranefly is the female of
Dictenidia bimaculata. Today I photographed the male in my garden. I'll send some photos of both insects to the gallery soon.
