Remarks on distribution.

Polistes dawnae, one of the two species characterized by a basally strongly swollen second metasomal sternum and recorded in northeastern Vietnam (the other is Polistes mandarinus), was originally described from Dawna Hills [16°50'N, 98°15'E], northern Myanmar, and has been recently recorded in northeastern part of Laos (Gusenleitner 2013) and northern Vietnam, such as in the provinces of Lai Chau, Dien Bien, Hoa Binh (Nguyen et al. 2011), Bac Kan and Son La (present study). This species may be restricted in its distribution to the areas on the eastern slope of the Himalaya.
