Dear Laci,

Your hypothesis of placement in 'Pseudochironomini' looks sensible, and the mentum reminds me of the second "major type" of Pseudochironomus larvae discussed and illustrated in John Epler's (2001) identification manual for the U.S. Carolinas (please see page 8.137 there).

One useful test may be to check whether the mandibular seta subdentalis is on the same (dorsal) side of the mandible as the seta interna, or on the opposite (ventral) side.

Cheers,

Martin Spies

Dear all,

This head capsule was found in the littoral sediment of lake Las Pozas, Guatemala. In my opinion it could be a Pseudochironomini, however, the genus name is a mystery to me. Do you know what is it? Also, if you dont but you know something about its ecology (you might have collected it), please let me know.
Thanks,
Laci
