MACIEL-BALTAZAR, Ebodio. New records of planktonic silicoflagellates (Dictyochophyceae) to the coast of Chiapas, Mexico. Hidrobiológica [online]. 2015, vol.25, n.3, pp.383-390. ISSN 0188-8897.

The silicoflagellates are a group of species with worldwide distribution, their determination is somehow problematic and rarely are abundant. In this study 10 species are described and illustrated, five are new records to the Gulf of Tehuantepec (D. californica, D. crux, D. franshepardii, D. fibula var. messanensis and D. octonaria), the presence of three species (Dictyocha calida, D. fibula y D. fibula var. robusta) is confirmed, the other two are considered as doubtful, one similar to the genus Corbisema and the other to the genus Mesosena. This work contributes to the knowledge of the geographic range and morphological variability of silicoflagellates.
