Mlíkovský, Jiří & Frahnert, Sylke, 2017, Type specimens and type localities of birds (Aves) collected during F. J. F. Meyen’s circumnavigation in 1830 – 1832, Zootaxa 4250 (1), pp. 1-22 : 9

Larus glaucodes Meyen, 1834a: 115 , pl. 24.

Now: Larus maculipennis M.H.C. Lichtenstein, 1823 (e.g. Dwight 1925: 298; Hellmayr & Conover 1948b: 281; Dickinson 2003: 148) or Larus maculipennis glaucodes Meyen, 1834a (e.g. A. Phillips in Belton 1984: 517; Howell & Dunn 2007: 313).

Syntype: ZMB 13462 skin, collected by Eduard Poeppig in 1827–1829 in Chile.

Syntype: ZMB 13463 ( Lichtenstein 1832, Nr. 73 sub “ Larus ”), skin, collected by Meyen in “ Maerz ” [= 1–15 Mar 1831; see below] in “ Chile ” [= bay of Valparaíso, Chile; see below]. For photos see Mallet-Rodriguez (2006: 177, fig. 3–4).

Type locality. “Die Küsten von Chile ” (“ Chilean coasts”) according to Meyen (1834a: 116). In his travel report, Meyen (1834b: 220) specified that these gulls were shot in the bay of Valparaíso. M.H.C. Lichtenstein (1832) reported that the specimen was collected in “ März ” (March). Considering Meyen’s itinerary (see above), he must have collected the specimen between 1–15 March 1831. Poeppig collected his syntype at an unknown locality in Chile . The type locality of Larus glaucodes Meyen is thus coastal Chile (including Valparaíso, Valparaíso Region, 33.05°S, 71.60°W).

Remarks. Meyen (1834a) called the species glaucodes in the text (p. 115) and glaucotes on the accompanying plate (pl. 24), respectively. Subsequently, both spellings, glaucodes (e.g. Boie 1844: 194; Cassin 1855: 204) and glaucotes (e.g. Meyen 1834b: 220; Bruch 1853: 105, 1855: 291; Lichtenstein 1854: 98; Bonaparte 1856: 771) have been used. The first author we found who mentioned both spellings, chose one and who can thus be considered as the First Reviser (sensu ICZN 1999, Art. 24.2.3) is Gray (1870: 114). Following his decision, the name should be spelled glaucodes .
