“…DNA barcodes accurately delimit species in a number of large-scale studies ( e.g ., birds, Hebert et al, 2004b ; Kerr et al, 2007 ; moths, Hebert, DeWaard & Landry, 2010 ; Hausmann et al, 2011 ; Huemer et al, 2014 ; beetles, Hendrich et al, 2014 ; bees, Schmidt et al, 2015 ; dipterans, Morinière et al, 2019 ). They are often useful for discovering cryptic species, as has been shown with butterflies and flies ( Hebert et al, 2004a ; Smith et al, 2006 ; Van Velzen, Bakker & VanLoon, 2007 ; Riedel et al, 2013 ; Espinoza, Janzen & Hallwachs, 2017 ; Janzen et al, 2017 ; Dias et al, 2019 ; Tujuba, Hausmann & Sciarretta, 2020 ). In many cases, BINs correspond with traditional taxonomy.…”

Background With about 1,000 species in the Neotropics, the Eumaeini (Theclinae) are one of the most diverse butterfly tribes. Correct morphology-based identifications are challenging in many genera due to relatively little interspecific differences in wing patterns. Geographic infraspecific variation is sometimes more substantial than variation between species. In this paper we present a large DNA barcode dataset of South American Lycaenidae. We analyze how well DNA barcode BINs match morphologically delimited species. Methods We compare morphology-based species identifications with the clustering of molecular operational taxonomic units (MOTUs) delimitated by the RESL algorithm in BOLD, which assigns Barcode Index Numbers (BINs). We examine intra- and interspecific divergences for genera represented by at least four morphospecies. We discuss the existence of local barcode gaps in a genus by genus analysis. We also note differences in the percentage of species with barcode gaps in groups of lowland and high mountain genera. Results We identified 2,213 specimens and obtained 1,839 sequences of 512 species in 90 genera. Overall, the mean intraspecific divergence value of CO1 sequences was 1.20%, while the mean interspecific divergence between nearest congeneric neighbors was 4.89%, demonstrating the presence of a barcode gap. However, the gap seemed to disappear from the entire set when comparing the maximum intraspecific distance (8.40%) with the minimum interspecific distance (0.40%). Clear barcode gaps are present in many genera but absent in others. From the set of specimens that yielded COI fragment lengths of at least 650 bp, 75% of the a priori morphology-based identifications were unambiguously assigned to a single Barcode Index Number (BIN). However, after a taxonomic a posteriori review, the percentage of matched identifications rose to 85%. BIN splitting was observed for 17% of the species and BIN sharing for 9%. We found that genera that contain primarily lowland species show higher percentages of local barcode gaps and congruence between BINs and morphology than genera that contain exclusively high montane species. The divergence values to the nearest neighbors were significantly lower in high Andean species while the intra-specific divergence values were significantly lower in the lowland species. These results raise questions regarding the causes of observed low inter and high intraspecific genetic variation. We discuss incomplete lineage sorting and hybridization as most likely causes of this phenomenon, as the montane species concerned are relatively young and hybridization is probable. The release of our data set represents an essential baseline for a reference library for biological assessment studies of butterflies in mega diverse countries using modern high-throughput technologies an highlights the necessity of taxonomic revisions for various genera combining both molecular and morphological data.

A long‐standing question in evolutionary biology is how historical biogeographic processes have shaped the current diversity of organisms, especially for highly diverse groups. We study the diversification dynamics and biogeographic processes of one of the most diverse families of Lepidoptera, Geometridae, with over 24,000 described species and a worldwide distribution. Despite the cosmopolitan distribution of the family, most species of Geometridae have limited distribution ranges. We present the largest historical biogeography and diversification study on the current diversity patterns and distribution ranges of Geometridae. We use a multi‐locus dataset of 1200 taxa to estimate the historical biogeography of Geometridae, implementing a Bayesian approach of the Dispersal‐Extinction‐Cladogenesis (DEC) model that incorporates palaeographic‐based dispersal graphs with uncertainty in geological ages in RevBayes. We also implement a Bayesian time‐variable, episodic birth–death model and a model that allows branch‐specific speciation rates to estimate the diversification dynamics in the family. Our results suggest that the most recent common ancestor of Geometridae was distributed in the New World, with the Neotropics being the most likely ancestral area. An increase in diversification rates occurred circa 30–40 million years ago (Mya), coinciding with a time of a major global climate cooling in the Eocene. Clade‐specific shifts in speciation rates also occurred around 10–15 Mya, coincident with another period of major climate change in the Oligocene. Our results point to different biogeographical and evolutionary histories per area to show the differences of the diversification rates in different biogeographical regions through time, showing the relative importance of each region in the diversification history of Geometridae.

The paper contains the description of two new species of the genus Morabia Hausmann & Tujuba, 2020: M. cryptica sp. n. and M. smithi sp. n. The descriptions are based on both morphological data and DNA barcoding. Based on integrative taxonomic analyses, five new combinations are proposed: Morabia nigripunctata (Warren, 1897), comb. n. described from Nigeria, Morabia hero (Viette, 1971), comb. n., Morabia pluto (Viette, 1971), comb. n. described from Madagascar, Morabia herbuloti (Orhant, 2003), comb. n. described from Réunion and Morabia distinctaria (Joannis, 1915), comb. n. described from Mauritius are transferred from the genus Ectropis Hübner, 1825 to Morabia. The female genitalia of M. nigripunctata, M. brunnea Hausmann & Tujuba, 2020, M. hero and M. herbuloti are described and illustrated for the first time. Detailed diagnoses and re-descriptions of all taxa newly transferred to Morabia are given, interspecific pairwise distances of DNA barcodes are calculated and a maximum likelihood tree is compiled. The paper is illustrated with 38 colour and 38 black and white diagnostic images and a distribution map.
