Dataset Information

A database and checklist of geometrid moths (Lepidoptera) from Colombia.

ABSTRACT:

Background

Molecular DNA sequence data allow unprecedented advances in biodiversity assessments, monitoring schemes and taxonomic works, particularly in poorly-explored areas. They allow, for instance, the sorting of material rapidly into operational taxonomic units (such as BINs - Barcode Index Numbers), sequences can be subject to diverse analyses and, with linked metadata and physical vouchers, they can be examined further by experts. However, a prerequisite for their exploitation is the construction of reference libraries of DNA sequences that represent the existing biodiversity. To achieve these goals for Geometridae (Lepidoptera) moths in Colombia, expeditions were carried out to 26 localities in the northern part of the country in 2015-2019. The aim was to collect specimens and sequence their DNA barcodes and to record a fraction of the species richness and occurrences in one of the most biodiversity-rich countries. These data are the beginning of an identification guide to Colombian geometrid moths, whose identities are currently often provisional only, being morpho species or operational taxonomic units (OTUs). Prior to the current dataset, 99 Geometridae sequences forming 44 BINs from Colombia were publicly available on the Barcode of Life Data System (BOLD), covering 20 species only.

New information

We enrich the Colombian Geometridae database significantly by including DNA barcodes, two nuclear markers, photos of vouchers and georeferenced occurrences of 281 specimens of geometrid moths from different localities. These specimens are classified into 80 genera. Analytical tools on BOLD clustered 157 of the mentioned sequences to existing BINs identified to species level, identified earlier by experts. Another 115 were assigned to BINs that were identified to genus or tribe level only. Eleven specimens did not match any existing BIN on BOLD and are, therefore, new additions to the database. It is likely that many BINs represent undescribed species. Nine short sequences (< 500bp) were not assigned to BINs, but identified to the lowest taxonomic category by expert taxonomists and with comparisons of type material photos. The released new genetic information will help to further progress the systematics of Geometridae. An illustrated catalogue of all new records allows validation of our identifications; it is also the first document of this kind for Colombian Geometridae. All specimens are deposited at the Museo de Zoología of Universidad de Sucre (MZUS), North Colombia. DNA BINs are reported in this study through dx.doi.org/10.5883/DS-GEOCO, the species occurrences are available on SIB Colombia https://sibcolombia.net/ and the Global Biodiversity Information Facility (GBIF) https://www.gbif.org/ through https://doi.org/10.15472/ucfmkh.

Project description:BackgroundThe geometrid moths of Europe are one of the best investigated insect groups in traditional taxonomy making them an ideal model group to test the accuracy of the Barcode Index Number (BIN) system of BOLD (Barcode of Life Datasystems), a method that supports automated, rapid species delineation and identification.Methodology/principal findingsThis study provides a DNA barcode library for 219 of the 249 European geometrid moth species (88%) in five selected subfamilies. The data set includes COI sequences for 2130 specimens. Most species (93%) were found to possess diagnostic barcode sequences at the European level while only three species pairs (3%) were genetically indistinguishable in areas of sympatry. As a consequence, 97% of the European species we examined were unequivocally discriminated by barcodes within their natural areas of distribution. We found a 1:1 correspondence between BINs and traditionally recognized species for 67% of these species. Another 17% of the species (15 pairs, three triads) shared BINs, while specimens from the remaining species (18%) were divided among two or more BINs. Five of these species are mixtures, both sharing and splitting BINs. For 82% of the species with two or more BINs, the genetic splits involved allopatric populations, many of which have previously been hypothesized to represent distinct species or subspecies.Conclusions/significanceThis study confirms the effectiveness of DNA barcoding as a tool for species identification and illustrates the potential of the BIN system to characterize formal genetic units independently of an existing classification. This suggests the system can be used to efficiently assess the biodiversity of large, poorly known assemblages of organisms. For the moths examined in this study, cases of discordance between traditionally recognized species and BINs arose from several causes including overlooked species, synonymy, and cases where DNA barcodes revealed regional variation of uncertain taxonomic significance.

Project description:A backbone molecular phylogeny of Mimallonidae, based on 47 species and 515 loci, was recently published. That study resolved some of the major relationships in the family, but taxon sampling was limited and a classification of the family was not formally presented for all species. Here morphological phylogenetic analyses in parsimony and maximum likelihood (ML) frameworks were conducted that included 192 species and 55 morphological characters. A phylogenetic analysis was also conducted on the morphological dataset with a topological constraint based on the 515 locus tree from the previous study. Results show that nearly all species can be confidently placed in a genus using morphological phylogenetics. The presence of a frenulum, a character that was historically used to distinguish major groups of Mimallonidae, varies within and among genera. Based on our phylogenetic results, the classification of Mimallonidae is revised, which now includes 291 species in 41 genera. Descriptions of three new genera are included: Fatellalla gen. n., Citralla gen. n., and Lepismalla gen. n. The following taxonomic changes were made in the present article: 43 new/revived combinations (in Aceclostria Vuillot, Arcinnus Herbin, Bedosia Schaus, Bedosiallo St Laurent & Kawahara, Cicinnus Blanchard, Citralla, Druentica Strand, Fatellalla, Lacosoma Grote, Lepismalla, Mimallo Hübner, Procinnus Herbin, Psychocampa Grote, Roelmana Schaus, and Thaelia Herbin), two new species-level synonyms (melini Bryk is synonymized with viemanda Schaus, jaruga Jones is synonymized with hamata Walker), one revived synonymy (roscida Dognin is resynonymized with externa Moore), seven new statuses (in Druentica, Macessoga Schaus, and Trogoptera Herrich-Schäffer), six revived statuses (in Aceclostria, Cicinnus, Druentica, Psychocampa, and Zaphanta Dyar), and one new designation of nomen nudum. In order to alleviate nomenclatural problems, twelve lectotypes are designated (for Tolypidaamaryllis (Schaus), Trogopteraalthora Schaus, Adalgisacroesa Schaus, Alheitapulloides (Dognin), LacosomabriasiaSchaus, Lacosomadiederica Schaus, Lacosomaraydela Schaus, Psychocampalacuna (Schaus), Cicinnuscorallina Dognin, Cicinnuslatris Schaus, Cicinnussolvens Schaus, Cicinnustuisana Schaus) as well as a neotype for Mimallodespecta Walker (= Cicinnusdespecta). This paper also provides apomorphies for each genus and a morphological key to genera. Annotations are given to aid researchers in understanding all changes made herein, and images of male and female and their genitalia are present for nearly all type species.
