SPHINX CENTROSINARIA Kitching & Jin, 1998

Sphinx centrosinaria Kitching & Jin, 1998, Tinea 15(4): 275.

Type locality: Ya'an, Sichuan Province, China.

(Taxonomic notes. (i) Closely related to S. crassistriga (Rothschild & Jordan, 1903) from Japan, some 3000 km away!)


BIOGEOGRAPHICAL AFFILIATION

Holarctic; eastern Palaearctic region. Pleistocene refuge: Monocentric -- Yunnan refugium.


ADULT DESCRIPTION AND VARIATION

Wingspan: 76mm. Closely resembles S. crassistriga, but the male with a more elongate, pointed forewing and more developed ventral lobe to the genital harpe. To quote Kitching & Jin "In its elongate forewing, centrosinaria resembles Sphinx formosana Riotte, 1970 from Taiwan. However, centrosinaria lacks the general dusting of pale grey scales found over the forewing upperside of formosana (which reduces the pattern contrast in this species), while the shape of the harpe in formosana is quite different from that of centrosinaria.
