PHYLLOSPHINGIA DISSIMILIS PERUNDULANS Swinhoe, 1897

TAXONOMY

Phyllosphingia perundulans Swinhoe, 1897, Ann. Mag. nat. Hist. (6)19: 64. Type locality: [India, Meghalaya,] Jaintia Hills.

Note. Recent studies indicate that this taxon is a distinct species, with a degree of overlap in range with the previous.

ADULT DESCRIPTION AND VARIATION

Wingspan: 120mm.

ADULT BIOLOGY

FLIGHT-TIME

China: ix (Guizhou).

EARLY STAGES

OVUM:

LARVA:

PUPA:

Larval hostplants. Unknown, but almost certainly Juglandaceae.

PARASITOIDS

Unknown.

LOCAL DISTRIBUTION

China: Yunnan (Bahand; Adunzi, nr Dêqên); Guizhou (Jiangkou); Hunan (Guzhang; Shangzhi).

The subspecific status of P. dissimilis outside of Yunnan and Hunan is uncertain. The population in Guizhou is most probably P. d. perundulans but those recorded from Fujian (Longqi Shan), Guangdong, Guangxi and Hainan could be either this subspecies, the nominotypical subspecies or intermediate forms. Study of specimens from these provinces is necessary to resolve the problem.

GLOBAL DISTRIBUTION

Occurs from Nepal, east through northeastern India, Burma/Myanmar and northern Thailand, to southwestern China.

BIOGEOGRAPHICAL AFFILIATION

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