Dorytomus tortrix

I found this on me as I was driving away having just been under, and parked under, some poplars. I used Duff to identify it, hitting a snag when keying it to genus. The tarsal claws were expanded towards the base and then narrowed just before the base. I would therefore have described the claw as toothed or appendiculate, but I had to key it as simple to get to Dorytomus. Keying it to species seemed fairly straightforward but it was a little more patterned on the elytra than I had expected for this species. I decided to dissect it to see if it had male genitalia which I could have compared to the photos at the Beetles of Europe website, but it proved to be a female. Having said that the spermatheca might be useful as it differs from that of a Dorytomus longimanus I examined at the same time, but I have no references that describe or illustrate this or most other Dorytomus spermathecae. The beetle was 5.1mm long.

I had previously recorded this individual at light in an area with lots of Aspen. It was 4.8mm long and would have been keyed using Duff. The Beetles of Europe website (coleonet.de) only has genitalia images for a few Dorytomus species but they include tortrix and this one's genitalia matches well (and doesn't match the other species shown there).
