Chrysanthrax or Hemipenthes? - Hemipenthes lepidota

Chrysanthrax or Hemipenthes? - Hemipenthes lepidota
Alluvial scrub on East bank, ~ 1000 ft., Eaton Canyon Natural Area, Los Angeles County, California, USA
September 13, 2006
Taking nectar in Lepidospartum squamatum (Scalebroom).
The nearly punctiform contact of the discal cell and the fourth posterior cell (see middle photo), together with the somewhat projecting , but rounded & blunt face, make me think that this is a Chrysanthrax . Can't see much otherwise, and not quite sure of genus (proboscis too long? Proboscis & antennae closer to Hemipenthes?). Perhaps a Hemipenthes? H. lepidota looks somewhat similar.
Comments appreciated!

H. lepidota
I believe you were correct with Hemipenthes lepidota. You can see the original description online at BHL, page 130, and it seems an exact match for this in all of the visible characters. I was just sorting through our AZ material and found some very similar specimens, and I'm pretty confident on the name. Whether it is a true Hemipenthes will have to wait until the genus is revised and redefined phylogenetically.

 
Thanks, Joel,
I'll take a look at this as soon as I have time, also understand need for revision.
Right now I'm looking at bees, but of course see many bombyliids around them.

ID - NOT!
I see this fly a lot, but I don't know Hemipenthes that well. I've assumed it was Hemipenthes, but I wouldn't wager on it. It's hard to say whether something belongs in Chrysanthrax or not because the genus is poorly defined and currently holds a diverse grab bag of species.

 
Thanks, Andy,
so for now I'll just keep this on tribal level.
