Novelties in Costa Rican aroids (Araceae) with nomenclatural notes

Background and Aims: Araceae is a worldwide family of herbaceous plants, most notable for its striking morphological diversity and broad habitat diversity. It comprises eight subfamilies, 143 genera, and 3667 species. The Central American region has about 780 species, of which 262 are distributed in Costa Rica. In this contribution, we include four new aroid records for the Costa Rican flora belonging to the genera Anthurium, Philodendron, and Spathiphyllum. In addition, nomenclatural aspects of A. myosuroides are discussed. Methods: The new records resulted from fieldwork on Fila Anguciana, Cerro Turrubares, and Volcán Miravalles. The correct taxonomic identity of the species was confirmed based on literature and comparison with herbarium specimens, especially type specimens from the herbaria of the Universidad de Panama (PMA) and the Missouri Botanical Garden (MO), as well as consultation of the JSTOR Global Plants database and the collections of the Muséum National d'Histoire Naturelle de Paris (P) online. Descriptions, taxonomic discussions, and figures of the morphological characteristics of the new records are provided. Key results: We present Anthurium roseospadix, A. myosuroides, Philodendron pseudauriculatum and Spathiphyllum dressleri as new records for the Costa Rican flora. Moreover, lectotypification for Pothos myosuroides is proposed. Conclusions: Considering the new records presented in this work, the aroid flora of Costa Rica now comprises 266 species, and the total species numbers for Anthurium, Philodendron, and Spathiphyllum increased to 94, 63, and 10, respectively.

The 19Th Century

The establishment in Costa Rica of the great naturalist Charles H. Lankester in the 19th century brought a tremendous increase in the knowledge of Costa Rican Orchidaceae. His desire to leave the collections kept at his farm for a scientific and educational purpose was finally accomplished in 1973 with the foundation of Lankester Botanical Garden (JBL). Since then, JBL has followed Lankester’s legacy with its consolidation as a leading center for the study of Neotropical orchids, resulting among others in more than 180 new Costa Rican species and records in the last 12 years. This manuscript includes the description of four new species and seven new records, as part of JBL’s contribution to the completion of the Costa Rican orchid inventory.

This catalogue contains literature reports and new records of Costa Rican Hepaticae and Anthocerotae, proceeding from monographs, revisions, floristic inventories, ecological bryophyte studies and herbarium specimens. The nomenclature has been updated in several genera. A total of 582 hepatic and eight hornwort species are reported from Costa Rica. The present work adds 26 new species records, and excludes 49 dubious records. Three new synonyms are proposed: Taxilejeunea carinata Herzog (=Lejeunea anomala Lindenb. & Gottsche); Taxilejeunea standleyi Herzog (=T. obtusangula [Spruce] A.

Central American Species

A revision of the Central American species of the genus Brachiacantha was undertaken to update the knowledge of the Central American species of the genus. Material of several collections was reviewed, using original descriptions and keys, and comparing with the type material. Twenty-five species of the genus Brachiacantha were found in Central American material, including nine new species: B. nubes Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. dentata Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. isthmena Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. aurantiapleura Nestor-Arriola, Solís and Toledo-Hernández, sp. nov., B. invertita Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. papiliona Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. tica Nestor-Arriola, Toledo-Hernández and Solís, sp. nov., B. hexaspina González, Větrovec and Nestor-Arriola, sp. nov., and B. mimica Nestor-Arriola and Toledo-Hernández, sp. nov. Nomenclatural changes include Brachiacantha gorhami (Weise), comb. nov., B. guatemalensis (Gorham), comb. nov., and Brachiacantha duodecimguttata Leng, syn. nov. for B. lepida Mulsant. The male genitalia of the species B. fenestrata Gorhan, B. octostigma Mulsant, B. aperta Weise, and B. cachensis Gorhan are described and illustrated for the first time. New records include B. indubitabilis Crotch and B. bipartita Mulsant (Costa Rica and Guatemala), B. gorhami (Weise) (El Salvador), and B. cachensis Gorham (Panamá). A key to the species is included.

Soft Bottoms

Echinoderms within the Eastern Tropical Pacific have mainly been studied in association with coral reefs. Investigations on echinoderms associated with soft-bottoms and estuaries are still scarce. The present study reports on the echinoderm species inhabiting the soft-bottom sediments of shallow-brackish waters adjacent to the largest river basin along the Pacific coast of Costa Rica, Térraba-Sierpe wetland. Nine species were recorded, three of them new records for Costa Rica: Luidia columbia, L. latiradiata, and L. superba. The most common species were L. columbia, Astropecten armatus, A. regalis, and L. latiradiata. This contributes towards current knowledge on the biodiversity of Térraba-Sierpe wetland and should be considered as a baseline upon which to monitor the effects of future impacts on this important mangrove area.

Saimiri Oerstedii

Central American squirrel monkeys Saimiri oerstedii are limited to Costa Rica and Panama, and have never been abundant. The Costa Rican population is now decimated. Based on our survey of squirrel monkeys throughout a large portion of the Costa Rican range of this species in 1996, we can confirm that at least 1246 squirrel monkeys remain in 26 spatially dispersed localities. Despite probable undercounts of squirrel monkeys within sites and potentially missed localities, the total population size should be considered far below a size that would provide longterm genetic viability. Deforestation and habitat fragmentation spurred by agricultural and tourism development are the familiar culprits contributing to this decline. Our strong recommendation is that future conservation efforts be targeted at the level of each specific locality, perhaps recruiting local, national and international sponsors. A focused strategy would allow management efforts to be tailored to the circumstances specific to each site and thus allocate scarce resources more efficiently.

Central American Species

Paper wasps (subfamily Polistinae) are one of the four main groups of eusocial insects in the Neotropics. They are medically important for the frequent stings inflicted on humans, but at the same time are valuable predators of pest insects. Nonetheless, there are no updated keys for the identification of the Central American species. Here we provide keys to the 18 genera and 106 species known to occur in Costa Rica, illustrated with one hundred original line drawings.

Primary Consumers

Although appendicularians are relevant primary consumers and are part of every zooplankton community, there is a lack of information on the species present in different ocean regions. Thus, regional identification guides are useful to develop datasets with high taxonomic resolution. Appendicularian species were identified in 33 epipelagic samples of zooplankton collected in several locations of Costarican waters. Eighteen appendicularian species were identified, of which 15 were found in the Pacific and only three in the Caribbean. Seven species are new records for Costa Rican Pacific waters (Appendicularia sicula, Fritillaria charybdae, F. cf. pacifica, F. tenella, F. pellucida f. omani, Oikoipleura fusiformis f. cornutogastra and Pelagopleura verticalis). Data for each species distribution in Costa Rica is presented together with a key for the identification of appendicularian species recorded in the Inter-American seas and the Eastern Tropical Pacific.
