Prob. P. bifascialis or P. cappsi
I have been studying images and specimens of
Petrophila
's in Texas for the past month or two. Aside from the present images and two records by Ann Hendrickson in Edwards County (which I have some doubts about), there are no other records of
P. kearfottalis
in Texas. MPG shows one dot which is apparently based on Ann's records; BOLD has no specimens from Texas. The Lep Soc seasonal database lacks any Texas records, and the species is not on the 2010 edition of Knudson & Bordelon's checklist. There are no
kearfottalis
specimens in the U.T. Insect Collection.
N.B.: The open black oval on the HWs is misleading in this case. In Munroe's monograph on the subfamily, he states that
kearfottalis
differs from *most* specimens of
P. bifascialis
in having a slender open loop on the HW rather than a solid oval, and further emphasizes that the solid spot in
bifascialis
is occasionally reduced to a loop like that of
kearfottalis
. Another poorly known species,
P. cappsi
, described from Kerr Co., TX, also has an open oval on the HW. I'm beginning to rely on the relative widths of the median yellow bands on the FW to separate these three: These two yellow bands are typically nearly of equal width in
kearfottalis
. See, for example,
this AZ image
. That said, both
bifascialis
and
cappsi
apparently have unequal width yellow median bands. So the present moth may be the open-loop version of
bifascialis
OR it might be the poorly known
P. cappsi
. Ugh.
On several Central Texas images uploaded recently on
iNaturalist.org
, you'll find that I had mislead everyone by erroneously identifying these open-loop
Petrophila
's as
P. kearfottalis
. I'm now in the process of notifying all the iNatters of the error of my ways and putting together a more detailed guide to the Texas species!

My defense
Sorry this is getting so lengthy.
Obviously you are using some original descriptions for your study and yours is a more scientific methodology which I am just learning to use. My personal study of the Texas
Petrophilas
, done in 2015, was a sight only study using my personal spread specimens collected at our ranch and in Schulenburg using primarily MPG information. I followed this visual study up by submitting 5 specimens to BOLD.
In my defense, MPG does show a dot on the Texas map for range of
P. kearfottalis
. THAT DOT WAS THERE WHEN I WAS MAKING MY VISUAL STUDY and I have never personally submitted any of my photographs or personal sightings to Moth Photographers. My photographs that appear there were submitted by others, primarily Maury Heiman.
P. cappsi
on MPG is shown ONLY for Arizona and the records on BOLD are non-public. I acknowledge that those BOLD photographs show the same HW marking that I attributed to
P. kearfottalis
, but I did not even LOOK at them because of the MPG range.
In the pictures on MPG for
P. bifascialis
, the HW marking is heavy. None of the open loop pictures are shown there.
As for my BOLD submissions, the results were as follows:
2
Petrophila
specimens, which I thought were
P. confusalis
(1 Texas dot on MPG map), was identified as
P. hepperni
for which MPG has no photographs and there was not a species page or picture on BG,
1
Petrophila
specimen which I had thought was
P. daemonalis
was placed in a separate BIN - nearest BIN was
P. nr. daemonalis
from AZ
2
Petrophila
specimens that I had thought were
P. daemonalis
in a different BIN with that BIN nearest being Petrophila Biolep 617 from Panama
None of my BOLD specimens were considered
P. bifasicalis
.
I have been preparing some additional specimens to send to BOLD in hopes that more will at least appear in the SAME bins. Perhaps sending more specimens to BOLD will enlighten us further.

No defense needed!
Ann, I hope my comment wasn't taken as a criticism of all the great work you have done/are doing! I value your contributions so much. I'm intrigued with the identity of
Petrophila
's in Texas--particularly the Hill Country--because they have been so confusing. Your efforts were seminal is peaking my interest in the group as a whole.
I'm putting the "finishing" touches--in quotes since no study like this is ever finished--on a guide to Texas
Petrophila
which will draw heavily on all of our Hill Country experience...and as you've seen, the current portrait is not at all clear. So my offering will be a "finished first draft". Watch for that soon.
Thanks as always for all your efforts and wonderful images.

Andrew, sorry for the wrong moves. I have really been studying this Genus for the last week at our place in Campwood where I had a number of species seen on nights close together.
I a think this placement is correct. Notice that the hind wing has a circular black line. P. bificalis has just one heavy line on a white background. I found out I had seen one as far back as 2012 at my place. Nice pictures.

Petrophila kearfottalis
Thanks for the comment.
Since I moved to Austin, Texas, in 2012, I saw Petrophila only this year, in June and July, total three times. Each specimen had a black circular line on the hindwings. However, none had an additional short black line just above the terminal black dots. Such a line is clearly visible on the P. kearfottalis photograph in the EOL. I wonder if that line has any taxonomic bearing.
Regards -
Andrew

Truthfully, I don't know. I have noticed the same thing, but there is nothing else that has the circular line, so I made a decision. I am sending my recently posted specimen to BOLD, so we may, sometime in the far future have a definitive answer. Until then, I think it is okay to leave it here. If BOLD has a specimen, I don't know how to search for it and I don't know where else to look. I also think I see some differences in the banding between the two species.
Have you been to UT to look at their pinned collection? Chuck Sexton used to mention doing that.

genus Petrophila
the species level becomes more difficult, but based on the hind wing hollow discal spot, I would suggest Petrophila kearfottalis - Hodges #4773

I agree, however
I agree, however, there are
Petrophila
species on MPG without images. This could be one of them. Moved to genus for now.
