Current knowledge of fungi from Neotropical montane cloud forests: distributional patterns and composition
Biodiversity and Conservation.
Montane cloud forests in the Neotropics harbor a great wealth of biological diversity and a large number of endemic species. Here, we present (i) a comprehensive data mining exercise of fungi from Neotropical montane cloud forests (NMCF), (ii) an extensive review of the current knowledge of fungal richness, distribution and composition, and (iii) a preliminary analysis of fungal endemicity in Mexican montane cloud forests. Based on a survey of literature and other sources, we assembled a database of 6349 records representing 2962 fungal species in NMCF. The computed individual-based species rarefaction curve remained non-asymptotic, and the extrapolation curve estimated an expected increment of 42% in the number of species by doubling the sampling effort. Fungal species richness was highest in NMCF from Mesoamerica, particularly from Mexico and Costa Rica. Fungi from Mesoamerica, Caribbean and South America are significantly different at diverse taxonomic levels, and there is a little overlap in the fungal species recorded from these regions. The analyses of endemicity of the Mexican dataset performed with parsimony and Bayesian methods were highly complementary. They showed the following areas of endemicity supported by the congruent distribution of fungal species: (i) two main regions in the Trans-Mexican Volcanic Belt (TMVB); (ii) a region in the southern part of Veracruz; and (iii) a region located in the eastern part of TMVB with affinities with Sierra Madre Oriental and the Chiapan-Guatemala Highlands. This last area was supported by five species of Glomeromycota and is consistent with an area of endemicity previously found in vascular plants. In this study, we provide a perspective on gaps in knowledge regarding the diversity and distribution of fungi in NMCF, and provide a full dataset of fungal records with geographical, bibliographic and taxonomic information.

The primary freshwater crabs of Guatemala (Decapoda: Brachyura: Pseudothelphusidae), with comments on their conservation status
Journal of Crustacean Biology.
The freshwater crabs of the family Pseudothelphusidae Ortmann, 1893 are restricted to the Neotropics and many species have an elevated risk of extinction. The majority of pseudothelphusids is considered to be data-deficient, which impedes the assessment of their vulnerability levels. More than 50% of pseudothelphusids are endemic to Guatemala, and half of the species are categorized as data-deficient. In order to update and broaden our knowledge of the freshwater crab fauna of Guatemala, several surveys were carried out from 2014 to 2015, combined with the examination of collections of freshwater crabs of Guatemala deposited in several museums. A total of 55 specimens comprising six pseudothelphusid species were collected. The most common species were Potamocarcinus armatus H. Milne Edwards, 1853 (20% of the material identified to the species level), Phrygiopilus ibarrai (Pretzmann, 1978), Raddaus bocourti (A. Milne-Edwards, 1866), and Potamocarcinus magnus Rathbun, 1896 (14.5% each). The collection of the Universidad del Valle de Guatemala consisted of 57 lots with 69 individuals of nine pseudothelphusid species; predominant species were R. bocourti (61.7% of all identified lots) and P. magnus (20.5%). The following species are reported here as new records for Guatemala: Elsalvadoria zurstrasseni (Bott, 1956), Raddaus mertensi (Bott, 1956), and two undescribed species (Phrygiopilus sp., Zilchia sp.). Almost half of the 17 freshwater crab species (including the two undescribed) are either data-deficient or not yet assessed, and 65% (11 species) are endemic to Guatemala. Conservation strategies are urgently needed to preserve the integrity of the sites and habitats occupied by freshwater crabs, along with studies aiming to fill the gap of the data-deficient species.

Chiroptera Neotropical 18(1) 1106-1110.
Field inventories of small mammals have resulted in the collection of five bat species previously unreported for Guatemala: Trinycteris nicefori (Sanborn 1949), Thyroptera tricolor Spix 1823, Eptesicus brasiliensis (Desmarest, 1819), Myotis thysanodes Miller & Allen 1928, and Eumops glaucinus (Wagner 1843). The range of M. thysanodes is extended 334 km from Chiapas southeastward to Central America. The five new records to Guatemala increase the documented total bat species to 104.
