Remarks on distribution.

The following three subspecies are currently recognized in Polistes strigosus : the nominotypoical subspecies known to occur in Laos, China and Taiwan; minimus Bequaert, 1940 distributed in Nepal, Malaysia (Sabah) and the Philippines; and atratus Das and Gupta, 1984 in India. The color form from Vietnam agrees with non of the above-mentioned subspecies. It has the head reddish brown, mesosoma dark yellowish brown with metanotum and propodeum dark yellow, metasomal terga I−III dark yellow, and the other metasomal terga brownish black (in some specimens, all metasomal terga dark yellow). This species is widely recorded from the provinces of Hai Phong ( Nguyen et al. 2005), Quang Binh, Quang Tri, Thua Thien Hue ( Nguyen and Ta 2008), Hoa Binh ( Nguyen and Pham 2011), Ha Giang, Cao Bang, Lang Son, Vinh Phuc, Bac Giang, Ha Noi, Nghe An, Ha Tinh (present study), and may occurs in eastern parts of Vietnam north of the Hai Van Pass.
