Description of diatom species of the genus Actinoptychus from the coast of Oaxaca, Mexico
Background and Aims: Within phytoplankton, diatoms are the most studied, even though confusions in identification still occur among species of some genera like Actinoptychus.

| description | Background and Aims: Within phytoplankton, diatoms are the most studied, even though confusions in identification still occur among species of some genera like Actinoptychus. The aims of this work was to determine and describe the morphology of the species of the genus Actinoptychus, present the new records that occur in the coastal area of Oaxaca, Mexico, and review the distribution of the species of this genus recorded in the Mexican Pacific.Methods: Twenty-four samples from five localities were analyzed: Corralero and Chacahua coastal lagoons, and Cacalotepec, Punta Colorada and Bahía Grande neritic zones in Oaxaca. A cleansing of frustules was performed, and permanent slides were made for identification. Specimens were observed in optical microscopy.Key results: Five species were identified on the coast of Oaxaca: Actinoptychus splendens, A. vulgaris, A. concentricus, A. aster and A. senarius, being A. aster, A. concentricus and A. vulgaris new records for the state. Detailed descriptions are provided for each taxon.Conclusions: The distribution range of Actinoptychus aster, A. concentricus and A. vulgaris is extended for the Mexican Pacific. The size intervals previously reported in the Mexican Pacific for A. aster, A. senarius and A. vulgaris are extended here. Additionally, morphometric and meristic data for A. concentricus are reported for the first time. |

Antecedentes y Objetivos: Dentro del fitoplancton, las diatomeas constituyen uno de los grupos mejor estudiados; sin embargo, se presentan confusiones en la determinación entre las especies de algunos géneros como Actinoptychus. Los objetivos de este trabajo fueron identificar y describir la morfología de las especies del género Actinoptychus, presentar los nuevos registros en la zona costera del estado de Oaxaca, México, y hacer una revisión de la distribución de las especies del género en el Pacífico mexicano.Métodos: Se analizaron 24 muestras de cinco localidades: las lagunas costeras Chacahua y Corralero, y las zonas neríticas Cacalotepec, Punta Colorada y Bahía Grande, Oaxaca. Se llevó a cabo una limpieza de frústulas y se realizaron preparaciones permanentes para poder identificar a las especies. Se utilizó microscopía óptica para las observaciones de los especímenes.Resultados clave: Se identificaron cinco especies en la costa de Oaxaca: Actinoptychus splendens, A. vulgaris, A. concentricus A. aster y A. senarius, de los cuales A. aster, A. concentricus y A. vulgaris constituyen nuevos registros para el estado. Se proporcionan descripciones detalladas de cada taxon.Conclusiones: Se amplía el intervalo de distribución de Actinoptychus aster, A. concentricus y A. vulgaris en el Pacífico mexicano. Se amplía el intervalo de tamaño reportado en el Pacífico mexicano para A. aster, A. senarius y A. vulgaris. Además, se presentan por primera vez los datos morfométricos y merísticos para A. concentricus.
