Macbrideola spinosispora is described as a species new to science based on material collected in a lowland tropical rainforest in Costa Rica. This new species can be distinguished from other members of the genus by the violaceous color of the sporotheca, the loose and flexuous capillitium and the conspicuously spiny spores. Images are provided of diagnostic morphological features.

Based on nucleotide sequences from three chloroplast DNA regions (rps16, rpl16, trnT-trnL), we infer detailed phylogenetic relationships within the subfamily Thunbergioideae (Acanthaceae) and among major lineages of the family as a whole. Taxa were sampled to cover the geographic distribution of Thunbergioideae and to include all subgenera of the largest genus Thunbergia. All other major lineages of Acanthaceae were sampled to test monophyly and intrafamilial position of Thunbergioideae. Both parsimony and Bayesian analyses support Thunbergioideae as monophyletic. The mangrove genus Avicennia is consistently placed as sister to Thunbergioideae although with only moderate support. Thunbergia and Mendoncia are both monophyletic in all analyses, and Mendoncia is placed as sister to Thunbergia plus Pseudocalyx. Relationships within the two largest genera Mendoncia and Thunbergia are highly resolved and most branches are strongly supported. Our results suggest that the existing morphology-based classification of Thunbergia partially holds, but needs revision. Based on the phylogenetic relationships we found it likely that a twining habit is ancestral for the genus Thunbergia. The thecal awns, characteristic for many species in the genus, have probably evolved from unicellular bristles. Longitudinal dehiscence over the whole length of the thecae, which is present in many Thunbergia species, most likely evolved from short slits or pores as present in Pseudocalyx and Mendoncia.

The vesper mouse, Nyctomys sumichrasti (Rodentia: Cricetidae), a poorly known, arboreal, nocturnal, rodent found in Central America, has been considered rare, and limited information is available about its biology, especially reproduction. We obtained vesper mice from several sites in Costa Rica and prepared them as scientific specimens with standard external measurements and reproductive data recorded. We expanded our dataset by including specimens from museum collections. Vesper mice have 1:1 sex ratios throughout their range. They reproduce year-round and litters may occur in rapid succession. Testis size is positively correlated with body mass; however, we could not determine the onset of sperm production. The onset of reproduction for females, based on mass, is variable but most females are parous by 60 g. Litter size is small with a mode of two, and embryos are not evenly distributed across the uterine horns. Vesper mice exhibit striking morphological differences in terms of tooth-wear and pelage patterns across their range. Much work is needed to fully appreciate N. sumichrasti, its role in tropical habitats, and its reproductive biology.

The coexistence of multiple species of short-tailed fruit bats (Phyllostomidae: Carollia) is common throughout the range of the genus. Previous studies of fecal and stomach contents have documented differences in dietary breadth and in habitat use as mechanisms by which these species may partition dietary niches. By comparing values of \ð15N and \δ13C across species of Carollia from 17 sites in Central and South America, we show that co-occurring Carollia frequently differ in dietary breadth, foraging habitats, and level of insectivory. Values of \δ15N, which tended to be enriched in C. castanea, depleted in C. perspicillata, and intermediate in C. brevicauda and C. sowelli, indicate trophic stratification. Values of \δ13C followed the opposite trend, tending to be enriched in C. perspicillata and depleted in C. castanea, suggesting interspecific differences in breadth of the foraging area. Isotopic comparisons among Carollia, other bat species, and potential food items at 5 of our sites illustrate that populations of Carollia tend to be trophically intermediate between strictly phytophagous and strictly insectivorous organisms, and, contrary to the paucity of insect remains found in fecal samples, indicate that the consumption of insects by Carollia is more common and potentially more important than previously was thought.
