Taxonomic novelties in the genus Campylospermum (Ochnaceae) Naturalis
Bissiengou, P.; Chatrou, L.W.; Wieringa, J.J.; Sosef, M.S.M..
Four new species, one with two subspecies, of the genus Campylospermum are described, all endemic or sub-endemic to Gabon. These are C. auriculatum, C. gabonensis, C. gabonensis subsp. australis, C. glaucifolium and C. occidentalis. Distribution maps and scans of the holotypes are provided as well as preliminary IUCN Red List assessments. New combinations for nine species formerly assigned to the genus Ouratea and/or Gomphia are proposed: C. andongensis, C. glomeratum, C. longestipulatum, C. lunzuensis, C. lutambensis, C. nutans, C. plicatum and C. warneckei. Finally, one taxon is raised from the variety to species level, leading to the new combination C. costatum.

Selaginella devolii (Selaginellaceae), a new species from Taiwan Naturalis
Chang, H.-M.; Lu, P.-F.; Hsu, T.-C.; Chiou, W.-L..
Selaginella devolii sp. nov. is described from four populations located in central and southern Taiwan. It is an annual prostrate lycophyte, growing on moist rocky slopes. Its diagnostic characteristics include its small size, tiny broadly ovate trophophylls, complanate strobili, and sporangia which are only formed at the ventral sporophylls. Notes on taxonomy and distribution and a line illustration are provided.

EXTINCTION RISK OR LACK OF SAMPLING IN A THREATENED SPECIES: GENETIC STRUCTURE AND ENVIRONMENTAL SUITABILITY OF THE NEOTROPICAL FROG PRISTIMANTIS PENELOPUS (ANURA: CRAUGASTORIDAE) Pap. Avulsos de Zool. (São Paulo)
RESTREPO,ADRIANA; VELASCO,JULIAN A.; DAZA,JUAN M..
ABSTRACT IUCN Red Lists have been a valuable tool to prioritize conservation plans in endemic neotropical frogs. However, many areas in this region are poorly known in terms of their diversity and endemism. Based on examined museum specimens of the threatened species Pristimantis penelopus we revised its geographic distribution and determined the habitat suitability using niche modeling techniques. Using a mitochondrial fragment of COI gene, we determine the phylogenetic position and the extent of the genetic variation across its distribution in Colombia. We present the first records of P. penelopus for the Cordillera Oriental, the western versant of Cordillera Occidental and the northern portion of the Cauca river basin. Based on the molecular...
