Petronia petronia tibetana Jacobi

Petronia petronia tibetana Jacobi, 1923: 31 (Tschuwo, Kansego) .

Now Petronia petronia brevirostris Taczanowski, 1874 . See Vaurie, 1959: 586; Moreau and Greenway, 1962: 25; Dickinson, 2003: 718; Eck and Quaisser, 2004: 308; and Summers- Smith, 2009: 810–811.

SYNTYPE: AMNH 717370, female, collected at Kansego (= Ganse, as on label), Sichuan, China, on 12 August 1915, by H. Weigold on the Stoetzner’sche Szetschwan- Expedition. From the Rothschild Collection .

COMMENTS: In the original description, Jacobi did not designate a type but listed a male from Tschuwo, collected on 3 November, and two males, two females, and one female [juv.?] from Kansego in August. According to Eck and Quaisser (2004: 308) there are three male syntypes in SNSD, one from Tschuwo and two from Kansego. The above specimen is labeled ‘‘ Petronia petronia tibetana Jac. ’’ and marked ‘‘Cotypus,’’ with the wing measurement given as 93 [mm.]. This measurement falls within the 91–94 [mm.] given by Jacobi (1923: 31) for August specimens. The specimen had not formerly been recognized as a syntype.

As noted by Vaurie (1972: 137), Weigold’s ‘‘Tibetan’’ specimens were not always from within the boundaries of what was later considered to be Tibet. This specimen came from Kansego in Sichuan. Israel (1919: pls. 7 and 10), who gave the itinerary of the expedition, showed Kansego on his maps and noted on page 95 that on 11 August it was nearing Kansego.
