A new species of Triacanthoneus Anker, 2010 is described from an anchialine cave near Akumal, Quintana Roo, Mexico.Triacanthoneus akumalensis sp. nov., is the fourth species in the genus and can be distinguished from the previously de-scribed species by the position of the sharp lateral teeth on the carapace, the length and shape of the rostrum, the eyes beingcompletely concealed by the carapace, the dentition of the major chela fingers, and the shape of the telson. The presenceof a pleural process in the new species represents a new character for the genus. The description of T. akumalensis sp. nov. increases the number of caridean genera having representatives in the anchialine systems of the Yucatan Peninsula to 11.

A new species ofCirolanaLeach, 1818, collected from Cenote Aerolito, Cozumel Island, Mexican Caribbean, is described.Cirolana(Anopsilana)adrianisp. nov. has a body 2.7× as long as wide, widest at pereonites 5-6; cephalon smooth, with small rostral point; pereonites without tubercles or ridges; antenna 2 not surpassing back of segment 2 of pereon; pleonite 4 lacking free ventrolateral margins; pleotelson as long as wide, smooth, with 9 distal robust setae; appendix masculina extremely long, 2× as long as endopod of pleopod 2. The main differences between the new species and the marine speciesCirolana(Anopsilana)jonesi(Kensley, 1987) andC.(A.)sinu(Kensley & Schotte, 1994), as well as the stygobitic speciesC.(A.)yucatanaBotosaneanu & Iliffe, 2000, the most similar known species ofCirolana(Anopsilana) in the region, are described. This is the second isopod of the genusCirolanarecorded from the karstic systems of the Yucatan Peninsula.

AbstractA new species of Nebalia is described from Ría Lagartos in the Yucatán Peninsula, Mexico, increasing the number of described species in this genus to 13. The species closely resembles a complex of species recognized for the tropical western Atlantic that will need further study. The importance of the shape of the denticles on the dorsal plconal segments 6 and 7 as a taxonomical character is discussed.

A New Species

Stephanosporamayana is presented as a new species from the Yucatán Peninsula, Mexico. This species is distinguished by the yellowish pileus, basidiospores with a small corona (4–6 × 1–2.5 µm), and variable size (8.0–17.0 × 6.0–11.0), thin pileus (21–40 µm) and the ecological association to lowland forest with Haematoxylumcampechianum, Gymnopodiumfloribundum, Coccolobadiversifolia, Metopiumbrownei and Pinuscaribaea. It differs from the American species of Stephanospora, like S.michoacanensis and S.chilensis, by its larger basidiospores. Descriptions, photographs and discussions are presented.

Se describe e ilustra a Lophiaris tapiae Balam & Carnevali (Orchidaceae: Oncidiinae). La nueva especie se conoce solamente del área de Escárcega y de los márgenes de los ríos Candelaria y Palizada en el estado de Campeche, México. Se compara con los representantes del complejo Lophiaris oerstedii, particularmente con L. andrewsiae, con la que se encuentra cercanamente relacionada. Se incluye un mapa de distribución de las especies y una clave de identificación para todos los taxa del complejo L. oerstedii. De acuerdo con los criterios del Método de Evaluación del Riesgo de Extinción de las Especies Silvestres en México (MER) se propone el estado de conservación en “peligro de extinción (P)” para L. tapiae.

Abstract A new stygobitic isopod from the anchialine systems of the Yucatan Peninsula, Mexico, is described, bringing the total number of anchialine isopods to seven. Curassanthura yucatanensis sp. nov. of the family Leptanthuridae is the first species of the genus to be recorded from a continental site. It can be distinguished from the other known species in the genus by the shape of the head, wider than long, and the number of robust setae (30) on the palmar margin of the propodus of pereopod 1.
