“…Thomson, 1997;Camacho-Rodríguez, Lozano-Vilano, 2004), who used non-standardized measurements. Some of the linear measurements of this analysis are consistent with those used in morphological studies for some taxa of the family Mugilidae and have found to be effective for taxonomical discrimination (e.g., Ibáñez-Aguirre, Lleonart, 1996;Cousseau et al, 2005;Ibáñez-Aguirre et al, 2006;González-Castro et al, 2008Konan et al, 2014). These last authors determined for the genus Mugil that the landmarks associated to the head region had a higher discriminative power.…”

Assessing population-level morphometric variation of the Mountain Mullet Agonostomus monticola (Teleostei: Mugilidae) across its Middle American distribution

Population-level morphometric variation of the Mountain Mullet (Agonostomus monticola) was assessed in 419 adult specimens from 25 sample sites (river basins) across its Middle American distribution (Pacific and Atlantic-Caribbean drainages). This analysis was based on 36 standardized linear measurements and 19 landmarks on geometric morphometrics approach. Discriminant function analysis (DFA) revealed 19 linear morphological characters with significant variation among groups. Geometrically, the most notable changes were associated to the curvature of the frontal region of the head, the anterior and posterior insertion of the first dorsal and anal fins. The resulting grouping based on the DFA and geometric morphometrics techniques (Pacific-A, Pacific-B and NE México-Caribbean) were similar to those previously recovered by genetic techniques, where the Pacific-B (Ayuquila river basin) was the most different group. Our results provide morphological evidence for considering Agonostomus monticola as a complex of evolutionary entities, represented by two forms in the Pacific Ocean and another in the Atlantic Ocean.Keywords: Discriminant analysis, Evolutionary entities, Landmarks, Middle American distribution, Morphometry. La variación morfométrica de poblaciones de la lisa de montaña Agonostomus monticola fue evaluada en 419 especímenes adultos recolectados en 25 sitios (cuencas) a través de su distribución mesoamericana (Pacífico, Atlántico y cuencas del Caribe). El análisis fue basado en 36 medidas lineales estandarizadas y 19 puntos de referencia basados en morfometría geométrica. El análisis de función discriminante (AFD) reveló 19 caracteres morfométricos con variación significativa entre grupos. Geométricamente, los cambios más notables estuvieron asociados con la curvatura de la región frontal de la cabeza y la inserción anterior y posterior de la primera aleta dorsal y de la aleta anal. Los agrupamientos resultantes del AFD y del análisis de morfometría geométrica (Pacífico-A, Pacífico-B y NE México-Caribe) fueron similares con los previamente definidos mediante técnicas genéticas. El grupo Pacífico-B (cuenca de Ayuquila) fue el más disímil. Nuestros resultados proveen evidencia morfológica para considerar a Agonostomus monticola como un complejo de entidades evolutivas, representadas por dos formas en la cuenca del océano Pacífico y una forma en la cuenca del océano Atlántico.

“…sp., and the body width at the origin of the pectoral fins (Pw) is slightly less than in other M. curema or M. rubrioculus n. sp. However, as noted above and by Ibanez‐Aguirre et al (2006), there seems to be quite large morphometric variation within Atlantic populations of M. curema . Therefore, none of the features discussed above reliably distinguish the lectotype from the other specimens of M. curema .…”

“…However, neither D1w nor Pb in the M. curema lectotype is outside the total range for all examined specimens on M. curema (wide‐ and narrow‐jawed morphotypes). Moreover, the body width can be strongly influenced by sexual maturation (Ibanez‐Aguirre et al , 2006). The anal fin base (Ab) and the pelvic fins (Vl) are longer than in other wide‐jawed morphotypes of M. curema and are comparable to wide‐jawed morphotypes of M. rubrioculus n. sp.…”

The original description of Mugil gaimardianus has created various taxonomic problems in the past since the description is ambiguous and the type specimen is apparently lost. The name M. gaimardianus could not be reliably applied to any known species and was suppressed by the International Commission on Zoological Nomenclature (ICZN) (Bulletin of Zoological Nomenclature, 51: 286–287, 1994). Nevertheless, karyological evidence has shown that there is a species of mullet in Venezuelan coastal waters that does not conform to the description of any other mullet from the Western Central Atlantic and has the feature of a red eye that was often used by earlier authors to define nominal M. gaimardianus. The purpose of this study was to make a morphological description of these unusual specimens, provide a morphological diagnosis from other species of Mugil present in the Caribbean and Western Central Atlantic and establish a valid name for the species.

“…The higher morphological variation in the specimens of M. curema especially in the Atlantic may be due to the presence of more than one population in the Gulf of Mexico or else that there are different phenotypes in the same sample (Ibáñez-Aguirre and Lleonart, 1996;Ibáñez-Aguirre et al, 2006).…”
