Tardigrada, Diversidad, REPSA, Ciudad de MéxicoResumen
Se recolectaron 5 muestras de musgo y 2 muestras de líquenes dentro de la Cantera Oriente en el sur de la Ciudad de México. En total, se registraron 110 tardígrados y 27 huevos pertenecientes a 2 órdenes (Apochela y
Parachela), 4 familias (Milnesiidae, Hypsibiidae, Macrobiotidae y Ramazzottiidae), 6 géneros (Milnesium, Hypsibius, Notahypsibius, Minibiotus, Paramacrobiotus y Ramazzottius) y 9 especies. Milnesium longiungue Tumanov, 2006, Notahypsibius pallidoides Pilato, Kiosya, Lisi, Inshina y Biserov, 2011 y Paramacrobiotus gadabouti Kayastha, Stec, Mioduchowska y Kaczmarek, 2023, representan nuevos registros para México. La especie Paramacrobiotus puma sp. nov. es nueva para la ciencia y se proporciona su descripción, respaldada por microscopía óptica de contraste de fases (MCF), microscopía electrónica de barrido (MEB) y análisis de secuencias de nucleótidos de 3 marcadores nucleares y 1 mitocondrial. Estos nuevos registros incrementan la diversidad del grupo a 87 especies en el país.
