Relaciones filogenéticas del género Anomala (Coleoptera: Melolonthidae: Rutelinae)
Ramírez-Ponce, Andrés;Morón, Miguel ángel;
Revista mexicana de biodiversidad , 2009,
Abstract: a phylogenetic analysis based on adult morphology that includes some genera included in the tribe anomalini is presented, to redefine the genus anomala samouelle, 1819, and evaluate its phylogenetic situation. the parsimony analysis, based on 46 species of 18 genera from several areas of the world, allowed us to test the monophyly of some genera and evaluate their taxonomic position, and to reveal that the generic limits are not clear. on the basis of the strict consensus cladogram there is reason to consider the american species heretofore included in anomala as members of a different genus, paranomala casey, 1915, stat. rev. some american species included in the genus callistethus blanchard, 1851 are transferred to paranomala, with exception of c. viduus (newman), a finding that supports the revalidation of the genus pachystethus blanchard, 1851, stat. rev. anomalacra casey, 1915 is synonymized with paranomala, and anomala carlsoni hardy is transferred to leptohoplia saylor, 1935. the descriptions and diagnoses of the genera anomala, paranomala, callistethus and pachystethus are updated and a generic key to the new world anomalini is provided with the new nomenclatural changes proposed.

Abstract: Se presenta un análisis filogenético basado en caracteres morfológicos de adultos de varios géneros de la tribu Anomalini para redefinir al género Anomala Samouelle, 1819 y evaluar su situación filogenética. El análisis de parsimonia, que incluyó 46 especies de 18 géneros procedentes de varias partes del mundo, permitió poner a prueba la monofilia de algunos géneros y evaluar su posición taxonómica, además de revelar que los límites de algunos géneros no son claros. Con base en el cladograma de consenso estricto existen evidencias suficientes para considerar las especies americanas hasta ahora incluidas en Anomala como un género diferente, al que corresponde nombrar Paranomala Casey, 1915, stat. rev. También se comprobó que algunas especies americanas incluidas en el género Callistethus Blanchard, 1851 deben incorporarse al género Paranomala, con excepción de C. viduus (Newman), la cual fundamenta la revalidación del género Pachystethus Blanchard, 1851, stat. rev. También se sinonimiza el género Anomalacra Casey, 1915 con Paranomala, y se transfiere Anomala carlsoni Hardy, 1976 a Leptohoplia Saylor, 1935. Se actualizan las descripciones y diagnosis de los géneros Anomala, Paranomala, Callistethus y Pachystethus y se incluye una clave de los géneros americanos de Anomalini que incorpora las definiciones y cambios nomenclaturales propuestos.

Acta zoológica mexicana , 2001,
Abstract: Se presenta un estudio faunístico de los Melolonthidae de la Reserva de la Biósfera El Triunfo, ubicada en la porción sureste de la Sierra Madre del Sur en el estado de Chiapas, México. Se efectuaron colectas con trampa de luz tipo pantalla, trampas con fruta fermentada y captura directa sobre plantas, durante 1997 y 1998, que aportaron 40 especies de 24 géneros de Melolonthinae, Rutelinae, Dynastinae, Cetoniinae y Trichiinae. El mayor número de especies se encuentra en los géneros Phyllophaga, Anomala y Cyclocephala. Se encontraron especies recientemente descritas de los géneros Yaaxkumukia, Anomala, Mesosternus, Parisoleoides, Chrysina, Plusiotis, Hologymnetis y Phyllophaga. Hoplia subcostata Bates y Plusiotis quiche Morón se registran por primera vez para México, y se confirma la presencia de Archedinusrelictus Morón y Krikken, especie relictual descrita de El Triunfo en 1990. La estimación de la riqueza de especies por esfuerzo de colecta indica que esta investigación aportaría el 70 % de las especies nocturnas de esta localidad. Con base en los ejemplares capturados, se presenta una clave preliminar para las especies de Melolonthidae de la reserva.
