Magnificus bouvieri ( Oberthür, 1913) comb. n.

( Figs 1 , 10 , 23b, 23d )

Hepialus (Phassus) bouvieri ( Oberthür 1913: 671)

Sthenopis bouvieri ( Nielsen et al. 2000: 850)

Examined material. Holotype ♂ MNHN: Verbatim label: Chasseurs indigènes des Missionnaires de [local collectors of the missionaries of] Ta-tsien-Loû, 1905 / ESN slide no. 2872/ Type.

Original description ( Oberthür 1913). “ Phassus bouvieri is close to regius, Str. , and roseus, Obthr. ; however, Phassus bouvieri does not present any vestige of the pink hue which characterizes regius and roseus . It is a very pretty species whose designs on the upper wings are very complicated and delicate.”

Female. Unknown.

Etymology. Named in honour of Eugène-Louis Bouvier, Professor of Entomology, MNHN ( Oberthür 1913).

Flight period. Unknown

Remarks. Forewing pattern with oblique white band (orange outline in Fig. 30b ) broken by dark brown patch over outer anterior and central discal cells. Very similar to M. zhiduoensis . Male genitalia ( Fig. 10 ) distinguished from all other species (where male is known) by larger and rounded lateral corners and broadly rounded anterior margin of the saccus. Sympatric with S. roseus ( Fig. 31 ).
