The dataset contains two records of moth specimens (Lepidoptera, Depressariidae) collected in 2011 and 2015 in continental Portugal. The study of these specimens resulted in the description of a new Portuguese endemic species, Depressaria infernella Corley & Buchner, 2019 based on differences found in the male and female genitalia and DNA barcodes in Corley et al. (2019). Specimens were detected and captured using a mercury-vapor lamp to attract the insects. Captured specimens were identified to species level and preserved in 96% ethanol or in dry storage. From each specimen a tissue sample, one leg, was removed to be used for DNA extraction. The DNA barcoding of these specimens was conducted within the InBIO Barcoding Initiative (IBI), funded by EnvMetaGen and PORBIOTA projects. DNA barcode sequences were deposited in BOLD (Barcode of Life Data System) online database. Collected specimens and DNA extracts are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).

The dataset contains eight records of moth specimens of the genus Ypsolopha collected from 2015 to 2017 in continental Portugal. The study of these specimens resulted in the description of a new species, Y. rhinolophi (Corley, 2019), present in northern Portugal and south-east France, similar to Y. alpella (Denis & Schiffermüller, 1775) and Y. lucella (Fabricius, 1775), based on clear differences in male and female genitalia and on DNA barcodes in Corley et al. (2019). Specimens were detected and captured by direct search of the environment during the day, with adults hand-netted and larvae reared to adulthood, and by night using mercury-vapor lamps to attract the insects. Captured specimens were identified to species level and preserved in 96% ethanol. A tissue sample, usually a leg, was collected from each individual, from which DNA was extracted. The DNA barcoding of these specimens was conducted within the InBIO Barcoding Initiative (IBI), funded by EnvMetaGen and PORBIOTA projects. DNA barcode sequences were deposited in BOLD (Barcode of Life Data System) and GenBank online databases. Preserved specimens and DNA extracts are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).

The dataset contains three records of moth specimens of the family Gelechiidae collected from 2015 to 2018 in continental Portugal. The study of these specimens resulted in the description of a new genus, Mondeguina Corley & Rosete, 2020, a new species M. atlanticella Corley & Rosete, 2020, and a new genus placement for Catatinagma agenjoi (Gozmány, 1954) previously in the genus Apatetris Staudinger, 1880 (Corley et al. (2020)). The new genus contains M. mediterranella (Nel & Varenne, 2012) and M. atlanticella Corley & Rosete, 2020, a new Portuguese endemic species, described based on differences found in the male and female genitalia and on DNA barcodes. Specimens were detected and captured using mercury-vapor lamps to attract the insects. Captured specimens were identified to species level and preserved in 96% ethanol. A tissue sample, a leg, was collected from each individual, from which DNA was extracted. The DNA barcoding of these specimens was conducted within the InBIO Barcoding Initiative (IBI), funded by EnvMetaGen and PORBIOTA projects. DNA barcode sequences were deposited in BOLD (Barcode of Life Data System) online database. DNA extracts are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).

The dataset contains one record of the species Cochylimorpha punctiferana (Ragonot, 1881) (Lepidoptera, Tortricidae) collected in continental Portugal in 2016.The study of this specimen resulted in the resurrection of the Portuguese endemic species C. punctiferana from synonymy with C. discopunctana (Eversmann, 1844) based on clear differences in female genitalia and DNA barcode by Corley et al. (2020). A tissue sample, one leg, was removed to be used for DNA extraction. Sequencing of the 658 bp COI DNA barcode was conducted within the InBIO Barcoding Initiative (IBI) and the DNA sequence was submitted to BOLD (Barcode of Life Data System) and GenBank databases. The preserved specimen and DNA extract are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).

The dataset contains five records of moth specimens of the genus Isotrias collected from 2012 to 2016 in continental Portugal. The study of these specimens resulted in the discovery of sexual dimorphism in the species Isotrias penedana Trematerra, 2013, and in the description of the previously unknown female of the species in Corley and Ferreira (2017). Specimens were detected and captured by direct search of the environment during the day, with adults’ hand-netted, and by night using mercury-vapor lamps to attract the insects. Captured specimens were identified to species level and kept in dry storage. A tissue sample, a leg, was collected from each individual, from which DNA was extracted. The DNA barcoding of these specimens was conducted within the InBIO Barcoding Initiative (IBI), funded by EnvMetaGen and PORBIOTA projects. DNA barcode sequences were deposited in BOLD (Barcode of Life Data System) and GenBank online databases. DNA extracts are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).

The dataset contains 11 records of moth specimens (Lepidoptera, Depressariidae) collected from 1988 to 2016 in seven South European and North African countries. The study of these specimens resulted in the description of a new genus, Rosetea Corley & Ferreira, 2019. The new genus contains two species previously placed in the genus Cacochroa Heinemann, 1870, Rosetea corfuella (Lvovsky, 2000) and R. rosetella (Corley, 2018), but also a new species, R. sara Corley & Ferreira, 2019, described based on differences found in the male and female genitalia and on DNA barcodes in Corley et al. (2019). Captured specimens were identified to species level and preserved in 96% ethanol, with one exception kept in dry storage. A tissue sample, one leg, was collected from each individual, from which DNA was extracted. The DNA barcoding of these specimens was conducted within the InBIO Barcoding Initiative (IBI), funded by EnvMetaGen and PORBIOTA projects. DNA barcode sequences were deposited in BOLD (Barcode of Life Data System) online database. DNA extracts are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).

The dataset contains one record of the species Borkhausenia crimnodes (Lepidoptera, Oecophoridae) collected in continental Portugal in 2014. This species, a southern hemisphere moth, had not been recorded in Europe before. The specimen was detected and captured by direct search of the environment and preserved in 96% ethanol. A tissue sample, one leg, was removed to be used for DNA extraction. Sequencing of the 658 bp COI DNA barcode was conducted within the InBIO Barcoding Initiative (IBI) and the DNA sequence was submitted to BOLD (Barcode of Life Data System) and GenBank databases. The preserved specimen and DNA extract are deposited in the IBI collection at the CIBIO (Research Center in Biodiversity and Genetic Resources).
