Misidentification. Nesotrinchus caeruleipennis (Fairmaire) sensu BELLAMY (1987, 1990 , 2005, 2008) – in fact N. caeruleipennis (Thomson) , is now N. thomsoni Bílý & Kubáň , nom. nov. (see below).

Type material examined. Nesotrinchus caeruleipennis (Fairmaire) : LECTOTYPE (designated here): ♀ ( BMNH), TONGA: VAVA’ U ISLAND: ‘Type [p] [round, red-framed label] / Dicercomorpha caeruleipennis Fairm. Vavao [h, Fairmaire’s handwriting] / Fidji Fairm.[h, Kerremans handwriting] / coeruleipennis Fairmaire Type [h, Kerremans’ handwriting] / D. coeruleipennis Fairmaire I. Fidji [h]’. Since the number of syntypes is unknown, we designate here the female specimen from BMHN as the lectotype to avoid any confusion in the future.

Nesotrinchus orientalis : PARATYPES: 7 JJ 5 ♀♀ ( BMNH), TONGA: VAVA’ U ISLAND: ‘ Tonga: Vavao. iii.1925. G.H.E.Hopkins. [p] / Pres. by Imp. Inst. Ent. Brit. Mus. 1930–555.

Other published records. Further type specimens of N. orientalis ( BELLAMY 1987) : TONGA: EUA ISLAND: Eua Isl., 21.viii.1975, J. C. Watt leg. (1 J (holotype), 2 ♀♀, NZAC). TONGATABU ISLAND: Haamea, ii.1956, N. H. L. Krauss leg. (1 ♀). VAVA’ U ISLAND: various data (24 spec.). NEW ZEALAND: NIUE ISLAND: various data (4 JJ 4 ♀♀). Deposition of paratypes other than those from the Eua Island not specified.

Biology and collecting circumstances. Four paratypes of Nesotrinchus orientalis from Vava’u Island are labelled: ‘Talau Forest, on tree trunks’ and 13 paratypes from Vava’u Island (Neiafu) were collected at 0–100 m a.s.l. ( BELLAMY 1987).

Remarks. We have studied the syntype of N. caeruleipennis ( Fairmaire, 1877) and 21 paratypes of N. orientalis and failed to find any differences. We regard them as conspecific, N. orientalis being a junior subjective synonym of N. caeruleipennis ( Fairmaire, 1877) .

Distribution. Pacific Islands: Tonga (Eua Island, Tongatabu Island, Vava’u Island), Niue Island.
