A New Species

Based on differences in hemipenial morphology we recognize two species of anoles related to Anolis polylepis: Anolis polylepis (Pacific versant of central and southern Costa Rica and western Panama, excluding the Osa Peninsula) and a species described herein which is restricted to the Osa Peninsula. The two species differ in hemipenial morphology (hemipenis bilobed in A. polylepis versus unilobed in the species from the Osa Peninsula) but show no discernable differences in external morphology (i.e., morphometrics, scalation, coloration, male dewlap). We therefore consider them to be cryptic species. At the neck of the Osa Peninsula where the ranges of the two species meet we detected a narrow (about 1 km wide) hybridization zone in which only individuals with an intermediate hemipenial morphology occur.

A New Species

We describe and illustrate a new species of Beilschmiedia, from the Osa Peninsula of Costa Rica. It is distinguished by its small flowers, which are turbinate to campanulate, with six fertile stamens and pubescent ovary, in addition it has alternate leaves along the twigs, with the lower leaf surface glabrous and not glaucous. In the field, it can be recognized by its stature, a very large tree, with the bark reddish, and peeling in large plates. Among described congeners it is superficially similar to B. hexanthera, from French Guiana, which also has six fertile stamens, and staminodes of whorl III columnar, but differs in having a pubescent ovary and larger, more branched inflorescences.

Calathea hylaeanthoides Kennedy, Calathea retroflexa Kennedy, and Calathea incompta Kennedy are described as new. All three species are endemic to Costa Rica. Calathea hylaeanthoides and C. incompta are from the Osa Peninsula, while C. retroflexa is from midelevation on the Pacific slope of the Cordillera de Talamanca. Calathea hylaeanthoides belongs to Calathea section Breviscapus, C. retroflexa belongs to Calathea section Calathea, and C. incompta belongs to the "Ornata group" of Calathea. Key words: Marantaceae, Calathea, Costa Rica, endemism.

A New Species

A new definition for the genus Moribaetis Waltz & McCafferty 1985 is given. Its type species, Moribaetis maculipennis (Flowers 1979) is redescribed based on male and female imagoes reared from larvae near the type locality in Panama. Larvae, formerly wrongly attributed to Moribaetis salvini (Eaton 1885), and a male imago, formerly wrongly attributed to Moribaetis macaferti Waltz 1985, belong to a new species Moribaetis latipennis sp. n., which is described here based on a male imago reared from larva in Panama. Both species, M. maculipennis and M. latipennis sp. n., are distinct from M. salvini, which is known as a single male imago (lectotype) from Costa Rica. All other species, formerly attributed to Moribaetis, are excluded from this genus; a new combination Caribaetis macaferti comb. n. is proposed for the species originally described as Moribaetis macaferti Waltz (in Waltz & McCafferty) 1985, and a new combination Baetis (Rhodobaetis) mimbresaurus comb. n. is proposed for the species originally described as Moribaetis mimbresaurus McCafferty 2007.

Se describe e ilustra Pleodendron costaricense, una especie de árboles muy rara en el bosque lluvioso de bajura del Pacífico Sur de Costa Rica. La única otra especie congenérica, P. macranthum, se encuentra ca. 2000 km al nordeste, en Puerto Rico. Hasta ahora, la única especie de Canellaceae conocida en Centroamérica era Canella winterana, principalmente de las Antillas, que llega a la Península de Yucatán en México.
