Myrmica weii

Nothing is known about the biology of .

Identification
Radchenko and Elmes (2010) – A member of the pachei species group. It well differs from M. pachei and M. villosa by the much coarser transverse rugosity on the propodeal and mesonotal dorsum and reticulated pronotal dorsum. Its head margins have numerous long suberect hairs, and by this feature it is similar to Myrmica pleiorhytida, Myrmica multiplex, Myrmica yunnanensis and Myrmica heterorhytida. It differs from the first species by its distinctly longer head (CI > 1.20 vs. < 1.15), it has a much lower petiole than M. multiplex (PI1 1.68 vs. < 1.55), and has coarser transversal rugosity on the alitrunk dorsum than M. yunnanensis and M. heterorhytida (number of the rugae on this area ≤ 20 vs. ≥ 25). In some respects M. weii resembles Myrmica inezae for which it was mistaken when first collected. It well differs from that species by its reticulated pronotal dorsum whereas the whole alitrunk dorsum of M. inezae is transversely rugose, and especially by the shape of petiole and propodeal spines.
