[Taxacom] Help with identification

[Tony Irwin]

Pectinate setae of this sort occur in many other arthropods, such as mites
and Ephemeroptera mouthparts (See
http://www.marietta.edu/~mcshaffd/phd/f33.gif ). If the type specimen can
be located, it might be possible to identify its origin, but I doubt it's
worth the effort!
