As Siphonaptera are 'almost' flies, maybe someone has also some knowledge in that group. Found in a park in Vienna. 2mm long

I'd call this Pulex irritans

Female, could be Xenopsylla cheopis.
Receptaculum seminis is not visible, so the determination is not accurate.

I has one antepigidial bristle, which is not present in Pulex irritans.

Best wishes, Tomi

Thanks for your input Tomi. It's good to question identifications - keeps us all on our toes! However, comparing Figures 40 and 48 in Whitaker's RES Handbook, it seems to me that on head chaetotaxy alone, Lorin's specimen cannot be Xenopsylla. The apparent antesensilial (antepygidial) seta is at a rather strange angle, and I wonder whether it is a displaced seta from elsewhere on the specimen? So I'll stick with Pulex for now. :)

A parasitologist, whom I sent this photo, also had it determined as P.i. He was not sure about the sex though
