The new species Eugenia naraveana is described and illustrated here. It is only known at the windward slopes of Cofre de Perote volcano, and it grows in the upper tropical montane cloud forest. Its closest relatives are Eugenia sotoesparzae and Eugenia mexicana, but they differ from the new species because they grow in tropical perennial forests and coastal dunes, in addition to the differences in their morphological structures. This new species breaks the typical altitude range of Eugenia in Veracruz, Mexico, being registered above 2,100 up to 2,600 meters.

We describe and illustrate Philodendron guadarramanum, a new species of Araceae from Tabasco, Mexico. This species grows in montane cloud forest and evergreen tropical rainforest at elevations between 700 and 1100 m. It is similar to Philodendron purulhense, but differs from that species by having petioles broadly and sharply sulcate adaxially, with an acute medial rib, leaf blades with more basal veins and more primary lateral veins per side, and inflorescences more numerous per axil.

We describe a new plethodontid salamander species of the genus Isthmura, known only from one locality in the mountainous region of central Veracruz, Mexico. Like its congeners, Isthmura corrugata sp. nov. has a large and robust body, but it is easily distinguished from the other species in the genus by the absence of any spot or mark on the dorsum (except by dull reddish brown coloration on eyelids) and by extremely well-marked costal grooves separated by very pronounced costal folds. Based on an mtDNA phylogeny, the new species is most closely related to the geographically distant I. boneti and I. maxima but occurs very near I. naucampatepetl and I. gigantea on the eastern slope of Cofre de Perote, Veracruz. The region where I. corrugata occurs contains a high number of plethodontid salamander species and is threatened by human activity.

AbstractRevision of lichen herbarium specimens at DUKE revealed a species of thelotremoid Graphidaceae new to science. Clandestinotrema carbonera sp. nov. is characterized by an olive-green thallus, dense cortex, the absence of a columella, ascospores 15–24 × 5.5–8.0 μm with 3–5 transverse septa (occasionally submuriform), and the presence of hypostictic acid as a major substance. At present the species is known only from the type locality, an area of montane cloud forest near Mérida, Venezuela. Interestingly, this species appears to have been discussed in the literature once before, as an unnamed ‘Thelotrema sp.’ which in the 1970s provided the first instance of hypostictic acid isolated from a lichen. The previous report of C. leucomelaenum from the same locality is shown to actually represent C. pauperius.

Ixchelia kochii Cuevas (Violaceae, Rinoreeae), a new species from western Mexico, is described and illustrated; it constitutes the third species of a recently described genus endemic to Mexico and Central America. The species grows in ecotones between tropical subdeciduous forest and montane cloud forest. The species of the genus are compared, and their relationships discussed.

A new species, Eucynorta rooneyi sp. nov. (Opiliones, Cosmetidae), is described from Parque Nacional Cusuco, Cortés, Honduras, a tropical montane cloud forest habitat. This is the thirty-fifth species of Eucynorta Roewer, 1912, and is characterized by the combination of three sexually dimorphic characters in males: enlarged chelicerae, some armature on femur III and IV, and swollen basitarsi on leg I. This new species is distinct from other Eucynorta species due to its unique pattern of yellow markings on area I of the dorsal scutum, and unarmed free tergites with line markings.

The new species Impatiens serusiauxii is described from Marojejy National Park in NE Madagascar. Impatiens serusiauxii differs from the morphologically similar I. manaharensis in the distinctly coriaceous linear-lanceolate leaves, the larger white flowers with dark red and yellow spots, the shape of the dorsal petal and the lateral united petals, and the shape of the lateral sepals and the lower sepal with spur oriented upwards. Impatiens serusiauxii is restricted to sclerophyllous montane cloud forest above 1100 m.
