Chyphotes sp.? - Chyphotes cooki - male

Chyphotes sp.? - Chyphotes cooki - Male
Ash Mountain, 2800' elev., Tulare County, California, USA
August 11, 1984
Size: ca. 10 mm.
Any ideas on the species? It really looks more like Typhoctes. This species is very different from the other Chyphotes in my collection.

Moved from Chyphotes.

Species added tentatively per below discussion.

Chyphotes sp.
This and the male are both in the genus Chyphotes since the 1st tergite does not connect to the mesosoma, it only reaches halfway across the 1st sternite.

Edit: Wait, I count 7 metasomal segments. I'm almost certain this is a wingless male, which would explain why it looks like a Typhoctes.

 
I'll have to take another loo
I'll have to take another look at it tomorrow, along with the other specimens like it. I only count six metasomal segments in the picture, with the possibility of seven.

 
It is a male! And twenty year
It is a male! And twenty years ago I even knew that. I put little labels on them with the male symbol. Its amazing how much you can loose with a little gin and time!

These males are wingless and show no signs of ever having wings.

 
When first looking at it I th
When first looking at it I thought it was a female as well! But tergite 1 didn't look right, as well as the mesosoma.

Chyphotes cooki is the only species where this has been reported in, but it sounds like it has occured in other species before too. The tegulae and wing bases are completely missing.

Very cool to have a wingless specimen!

 
Who would it be better to sen
Who would it be better to send Chyphotes to? You or Kevin Williams? Or are you interested in seeing material from California?

 
Kevin
Kevin would be better since he has almost certainly been studying bradynobaenids much longer than I have. I wouldn't mind seeing any extra specimens though to key out, since Chyphotes aren't too common in Texas.

 
I'm not very experienced with Chyphotes
I don't have much experience working with Chyphotes or the other bradynobaenids, but I can try to key it out with Mickel's paper. There is an unpinned wingless male that looks very similar to this one in the specimens you sent to me Dennis. If I remember right it is from a site pretty close to where this specimen was collected. I will try to identify it sometime soon. I wouldn't put too much faith in me though, as I have almost never identified any Chyphotes specimens.

Like George said, the only wingless Chyphotes I have seen are C. cooki, but the only wingless individuals of that species that I have seen are pretty much isolated to Cold Canyon, almost on the coast range. I would not be surprised if this is a different species that aptery has not been recorded in yet. I guess there's only one way to find out.

*Edited Friday* I worked a bit on the specimen that was with the other material you sent me Dennis. I think that it is C. cooki. The specimen is from a site fairly close to the specimen photographed here, so I am fairly sure that this one is C. cooki too. I could be wrong though, because the Chyphotes key is pretty difficult and I don't have much experience with it.
