Abstract: The preceding definitions of the tribe Poecilonotini Jakobson, 1913 are revised
and commented and a new concept of the tribe Poecilonotini sensu novo is
suggested. The subtribe Nesotrinchina Bílý, Kubáň & Volkovitsh,
subtrib. nov. is described and revised including a study of selected taxa of the
subtribe Poecilono- tina. Ulaikoilia jelineki Bílý & Kubáň, gen. nov.,
sp. nov. (subtribe Nesotrinchina subtrib. nov.) is described from Papua New
Guinea. The genus is diagnosed and compared with related genera and important
characters at the genus and species level are illustrated. The following new
synonymies are proposed: Lamprodila (Erialata) auripilis (Obenberger, 1922) = L.
(E.) pubescens (Fisher, 1930), syn. nov., Melobasina apicalis Kerremans, 1900 =
M. ignita (Théry, 1937), syn. nov., Nesotrinchus australicus (Kerremans, 1903)
= N. simondsi Obenberger, 1924, syn. nov. and N. caeruleipennis (Fairmaire,
1877) = N. orientalis Bellamy, 1987, syn. nov. Haplotrinchus marginefossus
Thomson, 1878, stat. restit. (Chrysochroinae Laporte de Castelnau, 1835,
Dicercini Gistel, 1848, Haplotrinchina Hołyński, 1993) is removed from
synonymy with H. pyrochlorus (Fairmaire, 1877) and restituted as a valid
species. Nesotrinchus Obenberger, 1924, stat. restit. is remo- ved from synonymy
with Melobasina Kerremans, 1900. A new substitute name is suggested:
Nesotrinchus thomsoni Bílý & Kubáň, nom. nov. for N. caeruleipennis
Thomson, 1878 (primary and secondary homonym). Lectotypes are designated for
Dicercomorpha caeruleipennis Fairmaire, 1877, D. caeruleipennis Thomson, 1878,
Haplotrinchus australicus Kerremans, 1903, Melobasina apicalis Kerre- mans,
1900, Nesotrinchus simondsi Obenberger, 1924 and Poecilonota suturalis
Deyrolle, 1864. The genus Pseudhyperantha Saunders, 1869 is transferred from
Stigmoderini Lacordaire, 1857 back to the tribe Buprestini Leach, 1815. Final-
ly, the following species are transferred to other genera: Melobasina suturalis
(Deyrolle, 1864), comb. nov. from Lamprodila Motschulsky, 1860; Nesotrinchus
wallisii (Montrouzier, 1855), comb. nov. from Haplotrinchus Kerremans, 1903; and
N. australicus, N. caeruleipennis and N. thomsoni Bílý & Kubáň, nom.
nov., all comb. nov. from Melobasina.
Key words: Coleoptera, Buprestidae, Buprestini, Dicercini, Poecilonotini, Neso- trinchina subtrib. nov., taxonomy, replacement name, synonymy, new combination, lectotype designation, Oriental Region, Australian Region, Pacific Islands
