Sphinx bhutana Brechlin, 2015, Entomo-Satsphingia 8(1): 17. Type locality: Bhutan, Paro Valley, 5km W Paro City, 11-12.vii.2009, 2820m.
Wingspan: 72--75mm. Similar in size to Sphinx yunnana Brechlin, 2015, but larger than Sphinx oberthueri (Rothschild & Jordan, 1903), but with male genitalia similar to the latter.
China: As yet, not positively recorded.
OVUM: Unknown.
LARVA: Unknown.
PUPA: Unknown.
Larval hostplants. Unknown.
China: As yet, not positively recorded.
Endemic to Bhutan (Dierl, 1975; Brechlin, 2015).
Records in the Chinese literature of Sphinx caligineus sinicus (Rothschild & Jordan, 1903) from southeastern Xizang/Tibet (Mutu, Namjagbarwa region, 850m) (e.g. Zhang et al., 1986, pl. 1, fig. 3) are usually misidentifications of Sphinx oberthueri; however, there is the possibility that the individuals could be Sphinx bhutana Brechlin, 2015 (or Sphinx yunnana Brechlin, 2015).
