Diagnosis
Medium-sized swallowtail butterdly. Wingspan 8-10 cm.
Forewing somewhat triangular, rounded at apex; hindwing
undulate at margin and bearing three tails arising from
M3, Cu1 and Cu2. Forewing ground colour black with several
longitudinal stripes across wings from submarginal, postmedial,
medial, subbasal to basal zones; underside of forewing
similar in colouration but with all veins tinged yellow
between marginal to postmedial zones; hindwing ground
colour black and with several yellow stripes; marginal
lunate patterns somewhat rectangular; postmedial, medial
and subbasal stripes much more developed than those in
former species; like B. thaidina, a red area ranging from
m1 to cu2 cells and associated with two whitish blue spots
below; underside similar to upperside, but with yellow
area more developed and black area paler. Female similar
to male in colouration but larger in size with forewing
much more rounded, and characteristic by bearing a sphragis
(Ackery, 1975; Saigusa & Lee, 1982). |

Distribution
This species is presently only known from Yuennan (Zhondian)
and Sichuan (e.g. Gonggashan and Hailougou) of China though
Collins and Morris (1985) suggested that record in Yuennan
was probably a mistake.
Habitat and Ecology Refer to previous species. The larval
hostplant is Aristolochia moupinensis and the larvae are
figured in Watanabe (1998: 18). |

Threats and Conservation Status
This species still faces strong threats from illegal collecting
and great demand of insect trading from Japan and Europe.
Local populations are also endangered by deforestation
and habitat alternation by improper forest management. |

Remarks
Bhutanitis pulchristriata Saigusa et Lee, 1993 has been treated as a synonym or a subspecies of Bhutanitis mansfieldi since no significant morphological difference could be found between them.
