AustraHanlycaenidbutterflygenusNacadubaMoore.[1881],Itisproposedthatitbe
given precedence over the senior subjective synonym Pepliphorus Hiibner. [1819],

first being '698. Pepliphorus Euchylas. HylasCram." and the second '699. P[apilio]

leadingtoPapiliohylasCramer,[1781](p. 142,pi. 363)andPapiliocyaneaCramer,
[1775] (p. 120, pi. 76), ofwhich P. cyanusFabricius, 1781 (p. 116)isan unjustified
emendation.AsnotedbyFruhstorfer{1916a,p.33)Hiibner'sspecificnameeuchylas
was a replacement name forhylas Cramer: there are at least three senior primary
homonymsofthelatter, theoldestbeingPapiliohylasLinnaeus, 1758(p.486).The
synonymyofeuchylasandhylasCramerwasmentionedbyRothschild(1915,p. 138),
Toxopeus(1927,p.267)andD'Abrera(1990,p.356).

Tite,1963;1 referencespublishedsince1981andadditionaltothosementionedinthis
applicationareheldbytheCommissionSecretariat).Nacadubapresently(Hirowatari,
1990)contains 38 species from the Oriental and Australian Regions, including the
South Pacific Islands. Recently two species of Nacaduba. N. berenice (Herrich-
Schaefier, 1869)andN.normaniEliot, 1969,havebeenrecordedaspestsofcocoain
Sabah,EastMalaysia,byFujii(1987)andPan&Morishita(1990)respectively.
5. Although Scudder'sdesignation (seepara. 2)ofcyaneaas the type species of
Pepliphorus was noted by Toxopeus (1927, p. 267) and Hemming (1967, p. 351),
