Revision of Belvosia Robineau-Desvoidy (Diptera, Tachinidae) and 33 new species from Area de Conservación Guanacaste in northwestern Costa Rica with a key to known North and Mesoamerican species.

Background: This revision is part of a continuing series of taxonomic work aimed at the description of new taxa and the redescription of known taxa of the Tachinidae of Area de Conservación Guanacaste in northwestern Costa Rica. Here we describe 33 new species in the genus Belvosia Robineau-Desvoidy, 1830 (Diptera: Tachinidae). All species described here were reared from this ongoing inventory of wild-caught caterpillars spanning a variety of families (Lepidoptera: Erebidae, Eupterotidae, Noctuidae, Notodontidae, Saturniidae, and Sphingidae). We provide a morphological description of each species with limited information on life history, molecular data, and photographic documentation. In addition to the new species, the authors provide a redescription of the genus Belvosia, as well as provide a key to the identification of the species present in the Meso- and North-American fauna. New information: The following 33 new species of Belvosia Robineau-Desvoidy, 1830, all authored by Fleming & Woodley, are described: Belvosiaadrianguadamuzi Fleming & Woodley sp. n., Belvosiaanacarballoae Fleming & Woodley sp. n., Belvosiaangelhernandezi Fleming & Woodley sp. n., Belvosiabrigittevilchezae Fleming & Woodley sp. n., Belvosiaalixtomoragai Fleming & Woodley sp. n., Belvosiacarolinacanoae Fleming & Woodley sp. n., Belvosiaciriloumanai Fleming & Woodley sp. n., Belvosiadiniamartinezae Fleming & Woodley sp. n., Belvosiaduniagarciae Fleming & Woodley sp. n., Belvosiaduvalierbricenoi Fleming & Woodley sp. n., Belvosiaeldaarayae Fleming & Woodley sp. n., Belvosiaeliethcantillanoae Fleming & Woodley sp. n., Belvosiafreddyquesadai Fleming & Woodley sp. n., Belvosiagloriasihezarae Fleming & Woodley sp. n., Belvosiaguillermopereirai Fleming & Woodley sp. n., Belvosiaharryramirezi Fleming & Woodley sp. n., Belvosiahazelcambroneroae Fleming & Woodley sp. n., Belvosiajorgehernandezi Fleming & Woodley sp. n., Belvosiajosecortezi Fleming & Woodley sp. n., Belvosiajoseperezi Fleming & Woodley sp. n., Belvosiakeinoraragoni Fleming & Woodley sp. n., Belvosialuciariosae Fleming & Woodley sp. n., Belvosiamanuelpereirai Fleming & Woodley sp. n., Belvosiamanuelriosi Fleming & Woodley sp. n., Belvosiaminorcarmonai Fleming & Woodley sp. n., Belvosiaosvaldoespinozai Fleming & Woodley sp. n., Belvosiapabloumanai Fleming & Woodley sp. n., Belvosiapetronariosae Fleming & Woodley sp. n., Belvosiaricardocaleroi Fleming & Woodley sp. n., Belvosiarobertoespinozai Fleming & Woodley sp. n., Belvosiarostermoragai Fleming & Woodley sp. n., Belvosiaruthfrancoae Fleming & Woodley sp. n., Belvosiasergioriosi Fleming & Woodley sp. n.Belvosiacanalis Aldrich, 1928 is reared and recorded from the inventory; new information relative to host is provided and the species is rediscribed.The following are proposed by Fleming & Woodley as new synonyms of Belvosia Robineau-Desvoidy, 1830: Brachybelvosia Townsend, 1927 syn. n., Belvosiomimops Townsend, 1935 syn. n.The following three new combinations are proposed as a result of the new synonymies: Belvosiabrasilensis (Townsend, 1927), comb. n.; and Belvosiabarbiellinii (Townsend, 1935), comb. n.The authors also propose the following new synonymies: Belvosiabrasilensis (Townsend, 1927) = Belvosiaaurulenta (Bigot, 1888), syn. n.; Belvosiapollinosa Rowe, 1933 = Belvosiaborealis Aldrich, 1928 syn. n.; Belvosiaweyenberghiana (Wulp, 1883) = Belvosiafuliginosa (Walker, 1853) syn. n.; Belvosiabrasiliensis Townsend, 1927 = Belvosiafuliginosa (Walker, 1853) syn. n.; Belvosialuteola Coquillett, 1900 = Belvosiaochriventris (Wulp, 1890) syn. n.; Belvosiasocia (Walker, 1853) = Belvosiaproxima (Walker, 1853) syn. n.; Belvosiachrysopyga (Bigot, 1887) = Belvosiaunifasciata (Robineau-Desvoidy, 1830) syn. n.; Belvosiachrysopygata (Bigot, 1888) = Belvosiaunifasciata (Robineau-Desvoidy, 1830) syn. n.

Integration of DNA barcoding into an ongoing inventory of complex tropical biodiversity.

Inventory of the caterpillars, their food plants and parasitoids began in 1978 for today's Area de Conservacion Guanacaste (ACG), in northwestern Costa Rica. This complex mosaic of 120 000 ha of conserved and regenerating dry, cloud and rain forest over 0-2000 m elevation contains at least 10 000 species of non-leaf-mining caterpillars used by more than 5000 species of parasitoids. Several hundred thousand specimens of ACG-reared adult Lepidoptera and parasitoids have been intensively and extensively studied morphologically by many taxonomists, including most of the co-authors. DNA barcoding - the use of a standardized short mitochondrial DNA sequence to identify specimens and flush out undisclosed species - was added to the taxonomic identification process in 2003. Barcoding has been found to be extremely accurate during the identification of about 100 000 specimens of about 3500 morphologically defined species of adult moths, butterflies, tachinid flies, and parasitoid wasps. Less than 1% of the species have such similar barcodes that a molecularly based taxonomic identification is impossible. No specimen with a full barcode was misidentified when its barcode was compared with the barcode library. Also as expected from early trials, barcoding a series from all morphologically defined species, and correlating the morphological, ecological and barcode traits, has revealed many hundreds of overlooked presumptive species. Many but not all of these cryptic species can now be distinguished by subtle morphological and/or ecological traits previously ascribed to 'variation' or thought to be insignificant for species-level recognition. Adding DNA barcoding to the inventory has substantially improved the quality and depth of the inventory, and greatly multiplied the number of situations requiring further taxonomic work for resolution.

DNA barcodes reveal cryptic host-specificity within the presumed polyphagous members of a genus of parasitoid flies (Diptera: Tachinidae).

Insect parasitoids are a major component of global biodiversity and affect the population dynamics of their hosts. However, identification of insect parasitoids is often difficult, and they are suspected to contain many cryptic species. Here, we ask whether the cytochrome c oxidase I DNA barcode could function as a tool for species identification and discovery for the 20 morphospecies of Belvosia parasitoid flies (Diptera: Tachinidae) that have been reared from caterpillars (Lepidoptera) in Area de Conservación Guanacaste (ACG), northwestern Costa Rica. Barcoding not only discriminates among all 17 highly host-specific morphospecies of ACG Belvosia, but it also raises the species count to 32 by revealing that each of the three generalist species are actually arrays of highly host-specific cryptic species. We also identified likely hybridization among Belvosia by using a variable internal transcribed spacer region 1 nuclear rDNA sequence as a genetic covariate in addition to the strategy of overlaying barcode clusters with ecological information. If general, these results will increase estimates of global species richness and imply that tropical conservation and host-parasite interactions may be more complex than expected.
