BG1301 D1549 - Doru taeniatum - Male
Barney Farm, Hwy 103, 1.0 mi. NW Washington, St. Landry Parish, Louisiana, USA
September 8, 2007
Size: BL 15 mm.(pincers incl.)
Collected on emergent vegetation at the edge of a pond. The second tarsal segment is wider than, and extends beneath, the terminal segment (see third photo). I believe this is diagnostic for the family Forficulidae. The "dark stripe" down the middle of the back points to the Genus Doru.
Confirmation/correction and proper placement would be appreciated.

Doru species
I'm having trouble differentiating Doru species. The only key I can find to all three NA species is Rehn & Hebard 1914. Based on this key, if the male pygidial spine is not as long or longer than the last abdominal segment, then it can only be D. lineare or D. aculeatum. The latter doesn't have exposed wings. Does this mean that all Doru images on BG (including this one) are D. lineare?

good point: lineare & taeniatum are synonymous...
guide page for the former deleted, pix moved

Moved tentatively -- better matches D. taeniatum (Dohrn)
compare male images in (1) and (2); both spp. occur in your area

Moved from Doru.

Spine-tailed Earwig (Doru aculeatum) family Forficulidae
This is a perfect match in the NWF Field Guide to Insects and Spiders (1) page 87. I just don't know if there are similar looking species.
Nice find and great photos as usual!
