Myrmica yani

Identification
Chen et al. (2016) - Myrmica yani is a remarkable new species, belonging to the pachei group.. So far, only three species (M. pachei, Myrmica inezae and Myrmica villosa) are recorded from the Himalayas which possess the key character of the whole mesosoma of dorsum bearing transverse rugae. Myrmica yani differs from the M. pachei and M. inezae by having a distinctly elongated head, with narrowly rounded posterior corners; posterior third of head dorsally without longitudinal rugae and reticulation, but densely punctate; petiole with distinct, short peduncle, its anterior surface slightly convex, meeting the dorsal one to form a blunt, narrowly rounded angle; dorsal surface short, gradually sloping posteriorly; body colored yellowish brown. It differs from M. villosa by the distinctly elongated head, with narrowly rounded posterior corners; posterior third of head dorsally without longitudinal rugae, but densely punctate; propleuron with densely micropunctures and dull; dorsum of propodeum with fine transverse rugae; anterior surface of petiole slightly convex, meeting the dorsal one to form a blunt, narrowly rounded angle.
