  • With the Discovery of a New Species of Oedipina from the Foothills Along
    With the discovery of a new species of Oedipina from the foothills along the Caribbean versant of Costa Rica (see the following article), the number of species of salamanders in the country has risen to 51. When compared to other countries, this diversity of salamanders places Costa Rica 5th among all countries on the planet, behind the United States (1st), Mexico (2nd), China (3rd), and Guatemala (4th). When considering countries with an area greater than 5,000 km2, the highest diversity density of salamanders is found in the small country of Costa Rica, with one species/1,000 km2.

Email: [email protected] ABSTRACT: I describe a new salamander of the genus Oedipina, subgenus Oedopinola, from two sites in Premontane Rainforest along the foothills of the central Caribbean region of Costa Rica, at elevations from 540 to 850 m. The type locality lies within the Guayacán Rainforest Reserve, a private reserve owned and operated by the Costa Rican Amphibian Research Center, located approximately 2 km north of Guayacán de Siquirres, in the province of Limón. The new taxon is distinguished from its congeners based on phenotypic and molecular (16S and cyt b) characteristics.

Reproduction takes place during the rainy months (September–March). During courtship, females emit reciprocal calls and both sexes perform vibratory movements of the body; the latter is described for the first time in anurans. Amplexus and oviposition occurred inside subterranean chambers. The temperature in closed chambers was lower than outside chambers, which may aid in reducing desiccation risks of eggs and tadpoles. Females were larger than males, but males had longer heads and shorter tibias, which may be related to digging. The study reinforces the importance of ongoing discoveries on anuran natural history.

AbstrAct. various species of frogs produce foam nests that hold their eggs during development. we examined the external morphology and histology of structures associated with foam nest production in frogs of the genus Leptodactylus and a few other taxa. we found that the posterior convolutions of the oviducts in all mature female foam-nesting frogs that we examined were enlarged and compressed into globular structures. this organ-like portion of the oviduct has been called a “foam gland” and these structures almost certainly produce the secretion that is beaten by rhythmic limb movements into foam that forms the nest. however, the label “foam gland” is a misnomer because the structures are simply enlarged and tightly folded regions of the pars convoluta of the oviduct, rather than a separate structure; we suggest the name pars convoluta dilata (pcd) for this feature.

Reserve. 3 Costa Rica is internationally recognized as one of the most biologically diverse countries on the planet in total species numbers for many taxonomic groups of flora and fauna, one of those being amphibians. Costa Rica has 190 species of amphibians known from within its tiny 51,032 square kilometers territory. With 3.72 amphibian species per 1,000 sq. km. of national territory, Costa Rica is one of the richest countries in the world regarding amphibian diversity density. Amphibians are under constant threat by contamination, deforestation, climatic change, and disease. The majority of Costa Rica’s amphibians are surrounded by mystery in regards to their basic biology and roles in the ecology. Through intense research in the natural environment and in captivity many important aspects of their biology and conservation can become better known. The Costa Rican Amphibian Research Center (C.R.A.R.C.) was established in 2002, and is a privately owned and operated conservational and biological research center dedicated to studying, understanding, and conserving one of the most ecologically important animal groups of Neotropical humid forest ecosystems, that of the amphibians.

However, this number is likely an underestimate due to the presence of many unexplored areas that are diffcult to access. Between 2012 and 2017, a monitoring survey of amphibians was conducted in the Central Caribbean of Costa Rica, on the northern edge of the Matama mountains in the Talamanca mountain range, to study the distribution patterns and natural history of species across this region, particularly those considered as endangered by the International Union for Conservation of Nature. The results show the highest amphibian species richness among Middle America lowland evergreen forests, with a notable anuran representation of 64 species.

Few species of caecilians are maintained in captivity and little has been published on their husbandry. We present data on substrate preference in a group of eight Central African Geotrypetes seraphini (duméril, 1859). Two substrates were trialled; coir and Megazorb (a waste product from the paper making industry). G. seraphini showed a strong preference for the Megazorb. We anticipate this finding will improve the captive management of this and perhaps also other species of fossorial caecilians, and stimulate evidence-based husbandry practices. INTRODUCTION (Gower & Wilkinson, 2005) and little has been published on the captive husbandry of terrestrial caecilians (Wake, 1994; O’ Reilly, 1996).
