Title: Six New Species of Burmeistera (Campanulaceae) from Ecuador
Six species of Burmeistera H. Karst. & Triana are described as new from Ecuador: B. chrysothrix Mashburn & Muchhala, B. crocodila Mashburn & Muchhala, B. erosa Mashburn, B. lingulata Mashburn & Muchhala, B. sierrazulensis Mashburn & Muchhala, and B. valdiviana Mashburn. These discoveries bring the total number of Burmeistera species in Ecuador to ca. 47. Descriptions are given for each species, as well as diagnoses to differentiate them from other Burmeistera. Also provided is a discussion of each species’ etymology, phenology, and ecology, a list of all specimens examined, and distribution maps and photos, when available. more »« less
Three species of Burmeistera discovered during fieldwork in Ecuador are described here. Burmeistera velutina and Burmeistera catulum are unusual in being nearly completely covered in indumentum, short and velvety in the former and remarkably long (up to 4 mm) and silky in the latter. Burmeistera jostii possesses bright red corollas, rare in a genus typically characterized by dull green flowers, and yellow to tan strigose hairs. We provide a discussion of each species’ etymology, phenology, and ecology, a list of all specimens examined, and distribution maps and photos.
A new taxon belonging to the genus Burmeistera (Campanulaceae, Lobelioideae) is described from El Quimi Biological Reserve in Morona Santiago Province, southeast Ecuador. Burmeistera quimiensis is characterized by its red-violet stems and veins, spiral phyllotaxy, bullate, ascending leaves with a revolute margin, puberulous abaxial leaf surface, cupuliform hypanthia, and thick-walled white to red-violet fruits with reflexed pedicels. Photos of the new species are given, as well as a distribution map of known collection localities, and its relationships with other species are discussed.

Abstract Premise Many tropical plants are bat‐pollinated, but these mammals often carry copious, multispecific pollen loads making bat‐pollinated plants susceptible to heterospecific pollen deposition and reproductive interference. We investigated pollen transfer between sympatric bat‐pollinated Burmeistera species and their response to heterospecific pollen deposition from each other. Methods We quantified conspecific and heterospecific pollen deposition for two populations of B. ceratocarpa , a recipient species in heterospecific pollen transfer interactions, that co‐occur with different donor relatives ( B. borjensis and B. glabrata ). We then used a cross‐pollination scheme using pollen mixtures to assess the species' responses to heterospecific pollen deposition in terms of fruit abortion and seed production. Results Burmeistera ceratocarpa received significantly more heterospecific pollen from its relatives at both sites than its own pollen was deposited on its relatives. However, heterospecific pollen deposition only affected seed production by B. borjensis and B. glabrata , but not by B. ceratocarpa , suggesting that early acting post‐pollination barriers buffer the latter against reproductive interference. Crosses between sympatric and allopatric populations suggest that the study species are fully isolated in sympatry, while isolation between allopatric populations is strong but incomplete. Conclusions We did not observe evidence of reproductive interference among our study species, because either heterospecific pollen deposition did not affect their seed production ( B. ceratocarpa ) or they receive heterospecific pollen only rarely ( B. borjensis and B. glabrata ). Frequent heterospecific pollen deposition might favor the evolution of barriers against foreign pollen (as in B. ceratocarpa ) that alleviate the competitive costs of sharing low fidelity pollinators with co‐occurring species.
Abstract—The genus Burmeistera consists mostly of cloud forest species occurring from Guatemala to Peru. Molecular work on this group has revealed previously established subgeneric groupings to be non-monophyletic, while also identifying several monophyletic groups with recognizable synapomorphies. One such monophyletic group is a clade of species with recurved corolla lobes which contains three species: B. crispiloba, B. sodiroana, and B. succulenta. As many as nine names have been recognized previously for these species, though the most recent taxonomic treatments recognize only these three. Additional collections of these species made in the last forty years have uncovered phenotypic variation showing that characters traditionally used to differentiate them no longer do so clearly and suggest the possibility of introgression between them. Here, we report morphometric analyses of herbarium specimens of the recurved corolla clade, using both hierarchical and normal mixture model-based clustering methods to test the current species hypotheses. Our results support the recognition of the three known species plus the newly described Burmeistera kitrinaima sp. nov. We provide complete descriptions of all four species, and include photographs, distributions maps, taxonomic discussion, and an identification key. Keywords—Andes, biodiversity, cluster analysis, hybridization, taxonomy.

Three new Neotropical athysanine (Deltocephalinae) leafhopper genera, Spaltumtettix Pinedo-Escatel & Dietrich gen. nov., Pseudonapo Pinedo-Escatel & Dietrich gen. nov., and Goiattus Pinedo-Escatel gen. nov., and 4 new species, S. coloradus Pinedo-Escatel & Dietrich sp. nov. (Peru), P. waorani Pinedo-Escatel & Dietrich sp. nov. (Ecuador), P. huanucensis Pinedo-Escatel & Dietrich sp. nov. (Peru), and G. reyesi Pinedo-Escatel sp. nov. (Brazil), are described and illustrated. In addition, the genera Zabrosa Oman, Napo Linnavuori & DeLong, Pseudalaca Linnavuori and Brazosa Oman are revised and redescribed. Six new species are described in Brazosa: B. campinacu Pinedo-Escatel & Dietrich sp. nov. (Brazil), B. espatula Pinedo-Escatel & Dietrich sp. nov. (Brazil), B. encrustada Pinedo-Escatel & Dietrich sp. nov. (Brazil), B. mildredireanae Pinedo-Escatel sp. nov. (Peru), B. negra Pinedo-Escatel & Dietrich sp. nov. (Peru and Bolivia) and B. beni Pinedo-Escatel & Dietrich sp. nov. (Bolivia). Brazosa caesarea Linnavuori & Heller comb. nov. is transferred to Spaltumtettix. The South American species Z. aquareza Linnavuori & DeLong syn. nov. is proposed as junior synonym of Z. unicampi Menezes. Keys to species of each genus are provided. Unusual aspects of the morphology of these genera are discussed and a comparative table is provided.
