Two new species and distribution records for the genus Bohayella Belokobylskij, 1987 from Costa Rica (Hymenoptera, Braconidae, Cardiochilinae).

ABSTRACT: Two new species of Bohayella Belokobylskij, 1987 from Costa Rica are described: Bohayella geraldinae Kang, sp. nov. and Bohayella hansoni Kang, sp. nov. These are new distribution records for the genus in the Neotropical region. In addition, a key to species of the genus Bohayella of Costa Rica is presented. The current work elevates the number of species included in Bohayella from nine to eleven.

Project description:The descriptive taxonomic study reported here is focused on Glyptapanteles, a species-rich genus of hymenopteran parasitoid wasps. The species were found within the framework of two independent long-term Neotropical caterpillar rearing projects: northwestern Costa Rica (Área de Conservación Guanacaste, ACG) and eastern Andes, Ecuador (centered on Yanayacu Biological Station, YBS). One hundred thirty-six new species of Glyptapanteles Ashmead are described and all of them are authored by Arias-Penna. None of them was recorded in both countries; thus, 78 are from Costa Rica and the remaining 58 from Ecuador. Before this revision, the number of Neotropical described Glyptapanteles did not reach double digits. Reasonable boundaries among species were generated by integrating three datasets: Cytochrome Oxidase I (COI) gene sequencing data, natural history (host records), and external morphological characters. Each species description is accompanied by images and known geographical distribution. Characteristics such as shape, ornamentation, and location of spun Glyptapanteles cocoons were imaged as well. Host-parasitoid associations and food plants are also here published for the first time. A total of 88 species within 84 genera in 15 Lepidoptera families was encountered as hosts in the field. With respect to food plants, these wild-caught parasitized caterpillars were reared on leaves of 147 species within 118 genera in 60 families. The majority of Glyptapanteles species appeared to be relatively specialized on one family of Lepidoptera or even on some much lower level of taxonomic refinement. Those herbivores in turn are highly food-plant specialized, and once caterpillars were collected, early instars (1-3) yielded more parasitoids than later instars. Glyptapanteles jimmilleri Arias-Penna, sp. nov. is the first egg-larval parasitoid recorded within the genus, though there may be many more since such natural history requires a more focused collection of eggs. The rate of hyperparasitoidism within the genus was approximately 4% and was represented by Mesochorus spp. (Ichneumonidae). A single case of multiparasitoidism was reported, Copidosoma floridanum Ashmead (Encyrtidae) and Glyptapanteles ilarisaaksjarvi Arias-Penna, sp. nov. both parasitoid species emerged from the caterpillar of Noctuidae: Condica cupienta (Cramer). Bodyguard behavior was observed in two Glyptapanteles species: G. howelldalyi Arias-Penna, sp. nov. and G. paulhansoni Arias-Penna, sp. nov. A dichotomous key for all the new species is provided. The numerous species described here, and an equal number already reared but not formally described, signal a far greater Glyptapanteles species richness in the Neotropics than suggested by the few described previously.

Project description:BackgroundThe Monteverde region of Costa Rica is a hotspot of endemism and biodiversity. The region is, however, disturbed by human activities such as agriculture and urbanisation. This study provides a list of orchid bees (Hymenoptera: Euglossini) compiled from field surveys conducted during January-October 2019 in the premontane wet forest of San Luis, Monteverde, Costa Rica. We collected 36 species of Euglossine bees across four genera. We provide new geographic distribution and elevation data for eight species in two genera. Due to their critical role in the pollination of orchids and other plants, the distribution and abundance of Euglossine bees has relevance to plant biodiversity and conservation efforts. This is especially important in a region with a high diversity of difficult-to-study epiphytic orchids, such as in the Monteverde region.New informationA total of 2,742 Euglossine male individuals across four genera (Eufriesea, Eulaema, Euglossa and Exaerete) were collected in this study. Updated geographic distributions and elevation ranges were established for eight species of Euglossini in two genera: Eufrieseamussitans (Fabricius, 1787), Eufriesearufocauda (Kimsey, 1977), Euglossadodsoni (Moure, 1965), Euglossadressleri (Moure, 1968), Euglossahansoni (Moure, 1965), Euglossaignita (Smith, 1874), Euglossatridentata (Moure, 1970) and Euglossaturbinifex (Dressler, 1978). These are the first recorded occurrences of these species in the Monteverde region of Costa Rica, according to the Global Biodiversity Information Facility (GBIF) database (https://doi.org/10.15468/9f9kgp). This study also established expanded elevation ranges for Euglossaallosticta, Euglossabursigera, Euglossamixta, Euglossaheterosticta and Euglossamaculabris, though these five species have been previously recorded in the Monteverde region and, thus, are not described in detail here. Additionally, our capture of 123 Eufrieseaconcava individuals is significant, as it indicates its abundance in this region. Prior to this study, there was a single record of E.concava in the Monteverde region, documented in 1993.
