Type material examined. LECTOTYPE (designated here): ♀ ( MNHN), FIJI: ‘Caeruleipennis (H. Deyr. M.s.s. Th. Type T. B. 38 I. Fidji / Th.Type [p] / Ex Musaeo James Thomson [p] / Type [p] [red label] / Muséum Paris 1952 Coll. R. Oberthür [p]’. Since the number of syntypes is unknown, we designate here the female specimen from MNHN as the lectotype to avoid any confusion in the future.

Additional material examined. FIJI: ‘Fiji [h] / cum typo comparavit Sv. Bílý [p] 2006 [h]’ (1 J, NMPC); ‘Fidji. [h] / Collection de Bonneuil [p] / Chalybeipennis ED. I. Viti. [h] / caeruleipennis H.Deyr. = coeruleipennis Thoms. Fidji [h]’ (1 ♀, BMNH); ‘caeruleipennis (HDeyr.) [HDeyr. is scratched] Fairm. I. Fiji [h] / Ex Musaeo Mniszech [p] Muséum Paris 1952 Coll. R. Oberthür [p]’ (1 ♀, MNHN).

Published records. FIJI: OVALAU ISLAND: no data, 1 spec., USPC ( BELLAMY 2005, 2008; as caeruleipennis Fairmaire – misidentification). VANUA LEVU ISLAND: Korovuli, 26.x.1977, on Agathis log [ Araucariaceae ], BPBM, CLBC ( BELLAMY 1990, 2005, 2008; as caeruleipennis Fairmaire – misidentification). VITI LEVU ISLAND: Colo-i-Suva, C.23, ex laulau leaves, 6.iii.1995, ex. resting on Garcinia myrtifolia leaves [ Clusiaceae ], 1 spec., FFDC; Navua Nakavu, ex. Mavota, 8.vi.1994, ex. Gonystylus punctatus [ Thymelaeaceae ], emerge in cage, 1 spec., FFDC (both data from BELLAMY 2005, 2008; as caeruleipennis Fairmaire – misidentification).

Biology and collecting circumstances. The specimen(s) from Vanua Levu were apparently collected on an Agathis log and the specimens from Viti Levu ‘ex laulau leaves […] ex. resting on Garcinia myrtifolia leaves’ and ‘ex. Mavota [= Gonystylus ] […] ex. Gonystylus punctatus , emerge in cage’ ( BELLAMY 1990, 2005, 2008).

Remarks. Nesotrinchus caeruleipennis ( Thomson, 1878) is a junior primary and secondary homonym of N. caeruleipennis ( Fairmaire, 1877) . The taxon was erroneously treated as a junior subjective synonym of N. caeruleipennis ( Fairmaire, 1877) , moreover some authors ( FAIRMAIRE 1881, KERREMANS 1892) mentioned the THOMSON’ s (1878) description only as a subsequent reference of N. caeruleipennis (Fairmaire, 1788) . BELLAMY (1987) misidentifed N. caeruleipennis ( Fairmaire, 1877) and N. caeruleipennis ( Thomson, 1878) and described specimens of the former species erroneously as N. orientalis . We propose a new subtitute name, N. thomsoni Bílý & Kubáň , nom. nov., to remove the existing homonymy.

Distribution. Pacific Islands: Fiji Islands (Ovalau Island, Vanua Levu Island, Viti Levu Island).
