Mimagoniates lateralis ( Nichols, 1913) Figs. 52-55

Coelurichthys lateralis Nichols, 1913: 151 (type locality: none, “These two small aquarium fishes were presented to the American Museum of Natural History by Mr. William Mack, of New York. There was no accompanying data, but they are probably South American, and are referred to the genus Coelurichthys of Ribeiro”). - Nelson, 1964a: 65 (found female type of C. lateralis difficult to identify and could not decide whether it was C. microlepis or same as C. tenuis , but if it were latter, C. lateralis would have priority because of page precedence).

Coelurichthys tenuis Nichols, 1913: 152 (type locality: none, same remarks as above under M. lateralis ). - Schultz, 1959: 63, (erroneously referred to M. inequalis ). - Nelson, 1964a: 62, 127 (considered male holotype valid species distinct from M. microlepis ). - Géry, 1966: 320 (questioned whether M. tenuis is synonym of M. lateralis ). - Géry, 1977: 362 (listed and noted that M. barberi of aquarists is apparently C. tenuis ). - Sterba, 1987: 69 (aquarium description).

Mimagoniates barberi (not of Regan, 1907: 402), Rachow, 1927: 17 (misidentification of M. lateralis for M. barberi ). Myers, 1928: 120 (misidentification). Rachow, 1928: 15 (misidentification). - Holly et al., 1950: 779, (misidentification; list of aquarium and ichthyological literature mostly referring to M. lateralis prior to 1941).

Mimagoniates inequalis Schultz, 1959: 11 , 63 (in part, misidentified specimens of M. lateralis, USNM 94117, as M. inequalis ).

Mimagoniates lateralis Weitzman & Fink, 1985: 106 , 109 (in list of material examined).- Weitzman et al., 1988: 404 (caudal skeleton, gland and entire specimens illustrated; discussion of phylogeny and biogeography). - Menezes & Weitzman, 1990: 385 (in key to species of Glandulocaudini ). - Machado et al., 2005: 73 (conservation status). - Guimarães et al., 1995: 185-189 (cytogenetic studies). - Weitzman et al., 1996a: 206, 209 (distribution; courtship behavior). - Weitzman, 2003: 226 (maximum length; distribution; remarks and references). - Menezes et al., 2007 (photograph; distribution; systematic status; synonyms; ecology and conservation status). - Menezes, 2007: 39 (listed in catalog; distribution; conservation status). - Menezes et al., 2008: 38-40 (distribution; discussion of relationships and biogeography). - Duboc & Menezes, 2008: 77 (conservation status; general informations; geographic distribution; main threats; conservation strategies).
