15 species are reported as new records for Bhutan. Unlike other 14 species, Vespa fumida is treated as new record as the present geographical location of Padong is in the Indian state of Sikkim. Moreover, during the entire study period, Vespa fumida and Polistes (Stenopolistes) nigritarsus are reported only from Ngatshang, Mongar and Pasakha, Chukha respectively with single female specimen each. Recording species from single location may indicate its rareness in Bhutan, while Parapolybia varia is found commonly throughout Bhutan with altitudes ranging from 349 m to 2073 m.
Dolichovespula lama has been reported from new altitudinal range of 1235 m above sea level. With exception of Vespula flaviceps, only females were caught and studied for Vespula vulgaris, V. structor and Dolichovespula lama. Therefore, the study of male specimens and the nest for Vespula vulgaris, V. structor and Dolichovespula lama are recommended.
