Xenox habrosus

Xenox habrosus
Eaton Wash, ~960 ft, Eaton Canyon Natural Area, Pasadena, Los Angeles County, California, USA

Saw two more the next day in other sections of this dry wash, as well as one in the same spot (perhaps same specimen) as the present one. Observed them to return to the same set of spots.
Larvae parasitize carpenter bees.

Xenox habrosus Xenox habrosus - female

species name?
Volume 3 of the Bombyliidae Catalog in PDF format here considers the Arizona/California Anthrax simson habrosus (Marston) a synonym of Xenox habrosus.

And it considers Anthrax simson (Fabricius) a synonym of Xenox nigritus, which occurs only in Mexico and farther south. There's no Xenox simson listed in the catalog. Are these old name now?

 
Hello Robin -
After Neal Evenhuis sent back the ID for this, I noticed the discrepancy with the World Cat. I asked whether this means that there are now three spp. extant in CA: delila , habrosus , and simson . His answer was in the affirmative.
ITIS lists 5 valid spp.: delila, habrosus, simson, tigrinus, xylocopae, the latter two not in CA. Most of their data on Diptera is based on BDWD project on which Evenhuis is co-editor. Probably no time for updating the World Cat.

 
good, thanks
This info should be on the species and genus pages for future reference.
