Previously, workers of species belonging to the pachei-group of the genus Myrmica were characterised by having only transverse rugosity on the alitrunk dorsum. The group contained only M. pachei and M. villosa, both endemic to the Indian side of the Himalaya. Three other species were recently described from China (M. taibaensis, M. polyglypta and M. well) that have at least some transverse rugae mixed with other types of sculpture on various parts of the alitrunk dorsum. Examination of new material collected from southern and south-western China and Kashmir revealed 9 new species sharing this feature. Here we redefine the pachei-group to include all 14 species; we review all the species, making a redescription of M. taibaensis and describe the 9 new species: Myrmica sculptiventris, M. schulzi, M. phalacra, M. varisculpta, M. hlavaci, M. pleiorhytida, M. multiplex, M. yunnanensis and M. heterorhytida. Drawings and measurements are provided together with a conventional key to workers of the pachei-group and a diagnostic table of the species.
