SUMMARY Ochtodes searlesii Mendoza‐González, Mateo‐Cid et Sentíes sp. nov. is described from Michoacán, tropical Mexican Pacific, on the basis of comparative morphology and rbc L sequence analysis. It is distinguished from other Ochtodes species by its erect axes arising from an encrusting base, its small terete fronds, regularly dichotomously branched axes, and obliquely divided zonate tetrasporangia. Phylogenetic analyses showed that three Pacific Mexican samples, from Caletilla, Zapote and La Majahuita (Michoacán), were identical and formed a distinctive and well supported Clade segregated from other species of Ochtodes from Brazil, Cuba, Ecuador, Guadeloupe and Mexico. The Mexican entity is morphologically distinct from other Ochtodes species as well. On this basis we propose a new Ochtodes species.
