Summary: | Baltileuctra dewalti Chen sp. nov., a new extinct species
of needle stoneflies (Leuctridae, Plecoptera), is described
and illustrated from the Eocene Baltic amber and compared
to the other leuctrids. Baltileuctra dewalti Chen sp.
nov. differs from both extant and extinct representatives of
Leuctridae by a combination of morphological characters
including wing venation, unique terminalia structures, and
cercal modification. The most distinguishable character
for the new taxon is the presence of two dentate long spines
lateral to a well-developed subanal probe. Several parasitic
mites are also found on the new stonefly. This is the earliest
known fossil evidence for mite parasitism in Plecoptera. |
