Material examined. 1 male (12.2 mm × 10.6 mm), dead on dock, Hanga Roa, Easter Island, coll. H. Tonnemacher, 29 August 1999 ( ZRC 2016.0123 View Materials ) ; 1 male (11.8 mm × 10.5 mm), 1 ovigerous female (10.9 mm × 8.5 mm), Easter Island, coll. L. H. DiSalvo ( LACM MBC 17835) ; 1 male (6.5 mm × 5.6 mm), 1 ovigerous female (5.6 mm × 4.3 mm), Piko , coll. C. B. Boyko & S. Reanier, 31 August 1999 ( ZRC 2016.0124 View Materials ) ; 2 males (7.4 mm × 6.3 mm, 8.2 mm × 7.2 mm), 1 ovigerous female (8.3 mm × 6.8 mm), Easter Island, coll. L. H. DiSalvo, 18 June 1986 ( LACM CR 19867022).

Geographical distribution. Southeastern Pacific Ocean (Castro et al. 2004).

Remarks. Castro (1997) parsed the identities of the specimens reported by Rathbun (1907) and Garth (1973), but it seems likely the later references by Garth (1985), Retamal (1981), Baez & Ruis (1985), Poupin (2003), and Retamal & Arana (2016) also refer to T. punctimanus . The figure of T. punctimanus given by Retamal (2004: fig. 19) certainly shows a specimen that very closely resembles one examined here, which was found dead on the dock at Hanga Roa (ZRC 2016.0123). We agree with the conclusion of Castro et al. (2004), who accepted the 1983 date for this species name. The name was first used in a dissertation ( Odinetz 1983) and subsequently in a journal article ( Odinetz 1984). Odinetz’s dissertation (1983) was nevertheless “obtainable, when first issued, free of charge or by purchase” (satisfying ICZN Article 8.1.2) and the name was not expressly disclaimed by the author in her dissertation (satisfying ICZN Article 8.2). At first glance, it may appear that this species name should be emended to punctimana, in order to comply with ICZN Article 34.2 mandating that Latinized adjectival species-group names must agree with the gender of the genus they are placed in and Trapezia is feminine. Odinetz (1983, 1984), however, did not provide a detailed etymology for her species name and manus can therefore be treated as a noun or an adjective. Because of this lack of etymology, the name is governed by ICZN Article 31.2.2 and is treated as a noun in apposition to the name of its genus.

Trapezia punctimanus is endemic to the southeastern Pacific, having been recorded only from French Polynesia and Easter Island ( Castro 2000).
