Montana. I have only a single specimen from Montana, 1090.1. This was collected at a rest stop near Anaconda, MT. The specimen is a female and it has some minor damage. It is a species in the genus Limonia, although I'll need additional material before I can settle on a species ID. We drove through this state pretty quickly on our way to Yellowstone and I didn't have the time to survey or collect much. This will definitely require another trip!
Wyoming. I wasn't able to spend very much time collecting in Wyoming. We were in Yellowstone for ~2 days and I didn't have permits. We did spend one night in the Big Horn Mountains on the eastern part of the state. This was an amazing campsite near Shell Creek. I managed to collect two different species at this locality (O'Grady 1091).
 Dicranota (Rhaphidolabis) integriloba (wing)  Dicranota (Rhaphidolabis) integriloba (habitus) | A single pediciid was taken, 1091.1. The separation of Sc1 and Sc2 is striking in this individual. Sc2 forms a crossvein between Sc1 and R about 1/2 down the length of Sc1. This is a member of the genus Dicranota (Rhaphidolabis). There are 31 Nearctic species and I've produced an updated key. I have one specimen from this genus, D. (Rhaphidolabis) integriloba, from Tilden Park near Berkeley (wing and habitus, at left). The Wyoming species keys to D. tehama, a species known from the Lassen area of Northern California. It is possible that this is a range extension or it could be that 1091.1 represents a new species. The wings possess a supernumerary crossvein in r not seen in D. tehama. Unfortunately, Alexander (1950) didn't illustrate or describe in the male genitalia of D. tehama so examination of the type will be necessary. I do have collections from near Lassen that might help shed light on this. |
There were also two females, each representing a different species of the genus Tipula from this locality. Additional material will be needed before I can assign these to subgenus and species.
