S. baboquivariensis
On 27 January I photo'd this moth and three others like it at my site on the Devils River. I had no idea what they were and my going through MPG images didn't find a match. I really wanted to find out what they were, so I put the images on BG and I called them to the attention of experienced moth folks. Six people offered IDs--two said Pleromelloida arizonata and four said Supralathosea baboquivariensis. Both are hairy gray moths. Each species has only one image at MPG (pinned) and none here or at iNat. At BOLD there are 5 images of P ariz and 15 images of S babo.

I looked at the five P arizonata at BOLD. Four were collected in the same 10 day period on the Mt Palomar road by the same collectors; the fifth was collected on the north side of Los Angeles in the same time period, but several years earlier. I can find no published report of the species in TX, but Ed Knudson stated he collected one in the Guadalupe Mts in early March.

Of the 15 specimens of S baboquivariensis at BOLD, 13 are from Texas. S babo are found all over TX, from Zapata to Sanderson, Iraan, Ft Davis, four from Big Bend NP and another outside the park, one from Ruidosa Hot Springs. Two S. babo were collected 10 days apart 5 mi N of Prescott AZ in late April/early May at 7000+ feet elevation. That is temporally, geographically, and thermally all around my record for these moths.

more on S babo
Looking at the five specimens of P ariz on BOLD and the pinned MPG specimen, I note that the P arizonata have a well-defined black ST line, a weakly developed or absent dark line on the inner margin of the (folded) FW, and darkly pigmented venation in the wings. Three of the specimens are darker than the one "darkish" specimen I have.

On the other hand, none the images of S babo show pigmented venation in the FW, none have much of an ST line, if any, and there is a conspicuous dark line along the inner margin of the (folded) FW on 14 of the 15 specimens at BOLD. This is in agreement with the four moths in the images posted here.

I am grateful for the input I had from all parties. Everyone contributed interesting info. I personally am convinced that this is S. baboquivariensis.

Pleromelloida arizonata?
Just a guess

Good hunting, that does look promising and would be a nice addition to the Guide!

Something from this Plate MPG. Possibly Genus Lithophane which likes the cold weather. Not something I recognize.
