Raveneliapiepenbringiae and Raveneliahernandezii, two new rust species on Senegalia (Fabaceae, Mimosoideae) from Panama and Costa Rica.

ABSTRACT: Two new rust species, Raveneliapiepenbringiae and R.hernandezii (Pucciniales) on Senegalia spp. (Fabaceae) are described from the Neotropics (Panama, Costa Rica). A key to the species on neotropical Senegalia spp. is provided. Molecular phylogenetic analyses based on 28S rDNA sequence data suggest that the representatives of Senegalia rusts distributed in the neotropics evolved independently from species known from South Africa. This is further supported by the teliospore morphology, which is characterised by uniseriate cysts in the neotropical Senegalia rusts and contrasting multiseriate cysts in the paleotropic Ravenelia species that infect this host genus.

Two new species of yellow-shouldered bats, genus Sturnira Gray, 1842 (Chiroptera, Phyllostomidae) from Costa Rica, Panama and western Ecuador.

Project description:Two new species of yellow-shouldered bats Sturnira Gray, 1842 (Chiroptera, Phyllostomidae) from Central America and western South America are described using molecular and morphological data. The two new species, which occur in Costa Rica and Panama and in western Ecuador, were previously confused with S. ludovici, and S. lilium and S. luisi, respectively. Sturnira now includes 22 described species, making it the most speciose genus in the Neotropical family Phyllostomidae.

Two new species of the Hagnagora anicata complex (Geometridae, Larentiinae) from Costa Rica.

Project description:Examination of the lectotype (here designated) reveals that Hagnagora anicata (Felder & Rogenhofer) does not occur in Costa Rica. Instead two new species are described, Hagnagora eliannesp. n. and Hagnagora unniasp. n., and their distribution is discussed. The previous treatment of Hagnagora anicata as a single widespread species ranging from Jamaica and Mexico to Bolivia needs to be critically evaluated.

Two new species and a new combination in Protium (Burseraceae) from Costa Rica.

Project description:Two new species of Protium (Burseraceae) are described and illustrated: Protium aguilariisp. nov., from the Pacific slope of the Osa Peninsula, Puntarenas Province, Costa Rica; and Protium hammeliisp. nov., from wet forests on the Caribbean slopes of Nicaragua and Costa Rica. In addition, Protium brenesiicomb. nov., is proposed as a new combination based on Trichilia brenesii, a name that was based on a specimen collected with flowers in the mountains near San Ramón, Alajuela Province, Costa Rica. It is compared with Protium costaricense, a similar species with which it has been confused for more than 90 years. Finally, illustrations and specimen citations are provided for all the aforementioned taxa, and some others with which they have been confused.

Four new species of Symmerista Hubner, 1816 (Notodontidae, Nystaleinae) from Costa Rica.

Project description:The genus Symmerista Hübner (Notodontidae, Nystaleinae) is reviewed for Costa Rica, based on 49 wild-caught specimens. Four species are newly described: Symmerista luisdiegogomezi Chacón, Symmerista inbioi Chacón, Symmerista minaei Chacón and Symmerista aura Chacón. All are from the cloud forests of the Talamanca moutain range, southern Costa Rica. Photographs of the adults, male and female genitalia, and barcodes are also provided. The species Symmerista tlotzin Schaus (1892) is removed from Symmerista and assigned to the genus Elymiotis Walker as a new combination.

Project description:BACKGROUND:We describe two new species in the genus Erythromelana Townsend, 1919 from Area de Conservación Guanacaste (ACG) in northwestern Costa Rica. Both species were reared from wild-caughtcaterpillars of Eois spp. (Lepidoptera: Geometridae). We provide a concise description of each species using morphology, life history, molecular data, and photographic documentation. NEW INFORMATION:Erythromelana jimmychevezi Fleming & Wood sp. nov.

Cryptic species within cryptic moths: new species of Dunama Schaus (Notodontidae, Nystaleinae) in Costa Rica.

Project description:Based on almost 1,700 recently reared and wild-collected specimens, the genus Dunama Schaus (Notodontidae, Nystaelinae) in Costa Rica is reviewed. Eight species are recorded of which seven are newly described: Dunama jessiehillae Chacón, Dunama jessiebarronae Chacón, Dunama janewaldronae Chacón, Dunama jessiebancroftae Chacón, Dunama janecoxae Chacón, Dunama biosise Chacón, Dunama indereci Chacón. Dunama angulinea Schaus is redescribed and associated with its correct genitalia. Dunama tuna (Schaus), previously listed as ocurring in Costa Rica, is restricted to Colombia. Most species are described through their distinctive CO1 barcodes, genitalia and life histories. Dunama adults and caterpillars, their foodplants, and their parasites in Area de Conservación Guanacaste (ACG) in northwestern Costa Rica are described where known. Many life history stages are illustrated.

Male and female terminalia were dissected and illustrated.

First record of the genus Venanus (Hymenoptera: Braconidae: Microgastrinae) in Mesoamerica, with the description of two new species from Costa Rica.

Project description:The New World genus Venanus (Hymenoptera: Braconidae: Microgastrinae) is a small group of parasitoid wasps that includes two Nearctic and seven Neotropical species. Here two additional species, authored by Fernández-Triana & Whitfield, are described from Costa Rica: V.johnnyrosalesi sp. n. from Area de Conservación Guanacaste (ACG) and V.randallgarciai sp. n. from Area de Conservación Cordillera Volcanica Central. They represent the first record of the genus for Mesoamerica. A previous key to all known Venanus (Whitfield et al. 2011) is modified to include the new species. The Costa Rican species were collected at altitudes of 1,400-1,460 m, but nothing is known of their biology. DNA barcodes were obtained for both species and are included as part of the description along with extensive photos. This paper is part of a series inventorying the diversity of Microgastrinae in ACG.
