Resumen

The increasing anthropogenic development of the Veracruz Metropolitan Area demands the updating and monitoring of the region’s biodiversity, particularly on the spatial-temporal dynamics of those potential indicator groups of any disturbance. We present the first study on the Tanaidaceans of the Lagunar System of Mandinga, Veracruz, Mexico. Seven collections were made on submerged vegetation and sediments in dry season from 2008 to 2015 and one in the rainy season of the first year. Organisms were collected with a dredger and a Renfro-like net on submerged vegetation. One species from the suborder Apsudomorpha, Discapseudes (Discapseudes) mexicanus Gutu, 2006 and two from the suborder Tanaidomorpha, Chondrochelia dubia (Krøyer, 1842) and Hargeria rapax (Harger, 1879). The former recorded the highest distribution and abundance during the study period, confirming that D. mexicanus is a tanaidacean characteristic of the coastal systems of the Gulf of Mexico and it is associated with environments with high organic content in the sediments, while the other species were collected with lower abundances. In general, the downward trend in its abundance is noticeable over time, a fact that can be attributed to the constant modifications and alterations that SLM has undergone throughout the study period.
