Comments

possibly new species
I showed these to my collaborator, Dr. Luis Mendes, he and I have been working on a new species in the Eastern USA, he described the only CA species. He indicated that this is a female Nicoletiidae. It's habitus and habitat indicate it may be a new species, maybe a new genus. It certainly is a new record for CA. I wonder if the CAS would be willing to send the specimen to Luis for him to examine? There are only a few people that work on this group worldwide.

 
Nicoletiidae specimen transmittal request response

"I'm glad that you found a specialist on the Nicoletiidae. Sure, we can send the specimen to Dr. Mendes. Do you have his address? Also, do you have the reference (or pdf, even better) of his description of the CA species?"

 
possibly new species
Thank your for your message! I will ask Mr. Ubick at CAS if the specimen may be sent to Dr. Mendes.
I will also let you know if an additional specimen is collected. I did see another about two weeks ago but failed to get it from my hand to a container. Note that I hand examined but did not collect two similar appearing insects in a nearby cave about twelve years ago. The cave is also the only habitat of a unique species of harvestman, Banksula tutankhamen.
Suggestions for trapping or other collection techniques are welcomed!

From Darrell Ubick, Calif Academy of Science, S.F.
I had a chance to look at the specimen and it is clearly a nicoletiid, since it lacks both compound eyes and ocelli. I could not locate a key to the genera of nicoletiids, and so have no idea what your specimen is. Have also checked the Cave Fauna of California MS which does not list nicoletiids. So, the specimen you picked up is a very nice record; congratulations!

from Dr. Engel: "Indeed, this is likely a nicoletiid."
Moved from Silverfish.

 
cavernicole Nicoletiid, sp.?
Thank you very much for helping me learn more about the specimen! I see the family is reported from sites in Florida, Texas, and Mexico.
I wonder what is known about the California distribution of Nicoletiidae?

Moved
Moved from ID Request. Michael Engel is another authority to contact, according to previous BugGuide discussion.

 
from Dr. Engel: "hard to tell from the photographs...
"...Are ocelli present? How many tarsomeres are present?"

Glen, could you answer the above Qs? =v=

 
Nicoletiidae not Tricholepidiidae?
Thanks for your interest-
Detail image I just posted indicates specimen has three, perhaps 4 tarsomeres, but not 5. I also see no evidence of ocelli in any images.
Therefore, per the ID gude, specimen is not a Tricholepidiidae, rather it is probably a Nicholetiidae?

 
your input has been forwarded to Michael
...together w/the link to the newly added pic

how exciting!
do both photographs show the same specimen? if so, pls link.
