Blastobasine coleophorid
This moth has transverse rows of spines on the dorsum of the abdomen, which diagnoses it to be a blastobasine coleophorid. The terminus of the abdomen indicates that it is male. Therefore, if it has a "notch" at the basal flagellomere of the antenna (see Fig. 2 here), then it is in either Asaphocrita, Holcocera, or Blastobasis; if it lacks the notch, then it is a Hypatopa.

Calosima is ruled out, because our spp. of that genus are white; likewise Pigritia, because your moth has labial palpi that are long enough to be visible in dorsal view (the right-hand one, at least, is clearly visible in your photo), whereas in Pigritia, they are so reduced as to appear to be almost absent. Sight ID of blastobasines beyond genus is beyond me.

it has the notch
any chance at Asaphocrita, Holcocera, or Blastobasis?

Probably Holcocera
By the form of the notch, I'd say this *probably* is Holcocera sp.

many thanks, Terry
I'll put it under that for now - perhaps someone else will weigh in some time.
