BG1969 D2151 - Tipula subeluta - female

BG1969 D2151 - Tipula subeluta - Female
Baton Rouge, Brookhollow Drive, East Baton Rouge Parish, Louisiana, USA
December 13, 2007
Size: body length 18.8 mm.
We think this may possibly be a female Tipula (Triplicitipula) tricolor. If it can be positivly identified, it represents the first BugGuide record for Louisiana.
Confirmation/correction would be appreciated.

The transverse brown stripe r
The transverse brown stripe running from the anterior sides of the shoulders to the katepisternum and maybe even the second coxae point to two species, T. maculipleura or T. subeluta, and eliminate T. tricolor. Furthermore, T. subeluta can be distinguished from T. maculipleura by the extent of the obliterative streak not reaching past the discal cell as shown here. A real life example of the mark of subeluta can be found here . The mark is a bit covered in yours, but I still see it. The mark is best seen when viewing the specimen from a side shot angled anteriorly like in the attached thumbnail.

The abdomen and wings are also nearly identical to the T. subeluta specimen I have (a generally more light browned or just browned appearance than tricolor, which seems to have more contrasting colors) outside of the darker lighting the attached thumbnail has. I have a specimen not posted anywhere online where the darkened tip of cell Bm is not very visible at all, so I think there is considerable variation in this trait, which may in part explain why this feature isn't evident in your specimen.

Edit: And you can see that the mark is clearly absent in T. tricolor here .
