On the species-group taxa of Taiwanese social wasps (Hymenoptera: Vespidae) described and / or treated by J. Sonan Author Kojima, Jun-Ichi Author Saito, Fuki Author Nguyen, Lien Thi Phuong text Zootaxa 2011 2920 42 64 journal article 46640 10.5281/zenodo.201805 f9385d5f-2207-403f-b7e9-4bd5440581be 1175-5326 201805 Polistes olivaceous (!) ( De Geer 1773 ) [mostly Polistes ( Gyrostoma ) jokahamae Radoszkowski 1887 ] Sonan (1943: 477) , listing Polistes hebraeus ( Fabricius 1787 ) and P. okinawensis Matsumura & Uchida 1926 as junior synonyms of P. o l i v a c e u s , stated that this species was common in lowland areas all over Taiwan Island. He listed, as example localities of its occurrence, Heitou, Kagi, Koshun, Rimogan in Bunsan-gun, Souzan and Taihoku. Starr (1992) regarded Sonan's “ P. olivaceus ” as P. jadwigae Dalla Torre [= P. jokahamae ; see Kojima and Hagiwara (1998) ]. We have examined 21 Ƥ and 11 3 in TARI that were identified as P. o l i v a c e u s by Sonan; they are from Ako, Hokoto (or Bokoto or Hookoto), Horisha, Kagi, Koshun, Nanto, Rimogan and Taihoku. All of them except one P. rothneyi Ƥ from Kagi were revealed to belong to P. j o k a h a m a e .
