“…Remarkably, we have found specimens with up to 10 layers, 2 more than previously reported. In L. variegata, the specimens examined are similar to previous reports from Mexico (Godínez-Ortega et al, 2018), Cuba (Torres-Conde et al, 2021), and other Caribbean localities (Camacho et al, 2019;Vieira et al, 2016;Vieira, Henriques et al, 2020;Vieira, Morrow et al, 2020), but the overall measurement ranges were smaller. This could be attributed to where sections were made or the developmental stage of the samples, which can make identification difficult based only on thallus thickness (Vieira et al, 2014).…”

“…Measurements of the medullar, subcortical, and cortical cells were made following the anatomical description used by Schultz et al (2015), using a Nikon Eclipse 50i microscope. Maximum and minimum values were obtained for each trait and compared with previous descriptions (Camacho et al, 2019;Godínez-Ortega et al, 2018;Torres-Conde et al, 2021;Vieira, Henriques et al, 2020;Vieira, Morrow et al, 2020).…”

Species of Lobophora (Dictyotales) are distributed throughout the sub-tropical and tropical seas worldwide. Recent analyses have revealed high species diversity in regions previously presumed to host only a single species, such as the Bismarck Sea, Eastern Pacific, Western Atlantic, Mediterranean Sea, and Greater Caribbean. Here, samples from Veracruz and Quintana Roo, Mexico, were collected, and 2 genetic markers (cox3 and psbA) were sequenced. The results confirmed the presence of L. dispersa and L. variegata. Lobophora dispersa is recorded for the first time on the Mexican coast. The distribution of its cox3 haplotypes shows genetic differentiation within the Greater Caribbean and Gulf of Mexico, possibly indicating limited dispersal and isolation by distance. Lobophora variegata exhibits lower genetic variability compared to L. dispersa, but its haplotypes did not show any obvious pattern. Lobophora declerckii, previously reported in the “Anegada de Afuera” reef, Veracruz, was not found, possibly due to its affinity to subtidal depths. Morphologically, L. dispersa and L. variegata align with previous descriptions, although we observed more variation in thallus cell thickness in L. dispersa. However, relying solely on morphological characters is insufficient to confidently identify the species, necessitating further sampling to determine the species diversity in Mexico.

Antecedentes y Objetivos: Desde la publicación del libro sobre las macroalgas marinas de Cuba en 2015 se han publicado nuevos registros y cambios taxonómicos. Por lo anterior, el objetivo del presente trabajo fue presentar una quinta revisión sistemática actualizada, que incluye Ochrophyta (Clase Phaeophyceae), Rhodophyta y Chlorophyta. Métodos: Se recopiló la información disponible en publicaciones científicas, tesis de licenciatura, maestría y doctorado, e informes científico-técnicos de especialistas reconocidos, considerando aquellas que no fueron comprendidas en la revisión anterior o que fueron publicadas después de 2015. Los taxones encontrados fueron ordenados sistemáticamente, los nombres actualizados y la sinonimia revisada según AlgaeBase y la literatura más reciente. Las especies se ordenaron alfabéticamente dentro de cada familia. La distribución de cada taxón se resumió para nueve zonas consideradas como Distritos Ecológicos (zonas) de la plataforma cubana.Resultados claves: Se presenta un listado florístico actualizado con 569 especies, una subespecie, 25 variedades y 21 formas. Se añaden a la anterior revisión 38 especies, de las cuales siete son nuevos registros para Cuba: Hydrolithon boergesenii, Neogoniolithon mamillare, N. propinquum, N. rhizophorae, Lithothamnion crispatum, Liagoropsis schrammii y Peyssonnelia rubra. Se da la distribución de cada uno de estos taxones en las nueve zonas de la plataforma cubana.Conclusiones: Las zonas que presentaron más especies son aquellas que han tenido un mayor esfuerzo de muestreo o donde predominan los fondos rocosos arrecifales, aunque no se han inventariado detalladamente las macroalgas en la zona mesolitoral, bahías y lagunas costeras.
