W.", a bluish green label: “8494”; 2 males (GMNH), all with the following labels: "♂/ Cochinchine/ M??? Saussure", a yellow determination label: "Corydia aenea Br. ♀"; MYANMAR: 1♀ (NHMV), "Palon/ ( Pegù) / L. Fea. VIII.IX.87", "Collectio Br. v. W.", a blue label: “19.084.”; 2♀♀ (GMNH), all with the following labels: "Palon/ ( Pegù)/ L. Fea. VIII.IX.87", "620/ 8g/ Birmania./ Indesor./ Mus. de Genes", two determination labels: "Corydia aenea Br. ♀" (yellow label), "Corydia aenea"; THAILAND: 1 male (NHM, No. #876266), "Thailand/ LOT. 2522 S. LOT/ Sam Ngow, Tak./ June. 12. 1959/? COLL", a label with number: “105”, "Pres by Com Inst Ent/ B M 1964-2", "Eucorydia aenea (Brunner)/ det. J. A. Meadows, 1968".

Diagnosis.

Total length (including tegmina) nearly 15.0 mm for male, 12.0 mm for female. Body metallic blue, head metallic blue, legs dark brown, tegmina metallic blue, anterior lateral margin of the tegmen with an elongate yellow spot, tegmen surface with circle white pubescence. Abdomen in ventral view brownish black, three segments orange laterally, in dorsal view dark with metallic blue, three segments orange laterally.

Remarks.

This species is characterized by tegmina with two elongate yellow spots, whitish pubescence, and the abdomen with lateral portions orange emarginated. The original description didn’t mention how many specimens were designated as types. We found three specimens from NHMV which were all labeled "Ostindien, fr. Fieber, Coll. Br. v. W.". None had a type label, except one with a red label which was handwritten with an illegible letter. We consider this specimen as the one which Brunner von Wattenwyl studied (Brunner von Wattenwyl 1865); it is the only one to possess an opened tegmen and wing, and the original description paid much attention to the tegmen and wing. Also, because of the red label, we designated it as the lectotype.

Walker (1868) reported Eucorydia dasytoides var. β from Siam as "abdomen beneath with a large luteous patch on each side. Fore wings without a band, but with an elongated spot on the costa". This description and locality agree with E. aenea , so we consider this E. dasytoides var. β as E. aenea .

Distribution.

East India, Thailand, South Vietnam, Myanmar.
