Erebia epiphron and Erebia orientalis: sibling butterfly species with contrasting histories

The butterfly genus Erebia (Lepidoptera: Nymphalidae) is the most diverse in Europe and comprises boreo-alpine habitat specialists. Populations are typically fragmented, restricted to high altitudes in one or several mountain ranges, where habitat is relatively well preserved, but where the effects of climate change are considerable. As a result, the genus Erebia has become a model to study the impact of climate changes, past and present, on intraspecific genetic diversity. In this study, we inferred phylogenetic relationships among populations of the European species Erebia epiphron and Erebia orientalis using mitochondrial (COI) and nuclear markers (ITS2, wg and RPS5), and reconstructed their phylogeographical history. We confirm E. orientalis and E. epiphron as a relatively young species pair that split c. 1.53 (±0.65) Mya. The high genetic homogeneity of E. orientalis, combined with its restricted geographical range in the eastern Balkans, suggests that this taxon may be subject to inbreeding depression and displays low adaptability to potential environmental changes, which calls for close monitoring of population trends. By contrast, genetic structure was complex for E. epiphron, revealing an intricate phylogeographical history that included a succession of dispersal events, mixing of populations and periods of isolation in multiple refugia. Finally, we highlight southern populations that represent unique genetic lineages, which, in the case of extinction, would lead to important genetic erosion.We thank the association ZERYTNHIA (http://www.asociacion-zerynthia.org/) for its support and the government of La Rioja for financing a specific study some years ago, as well as for the administrative authorization for the collection of samples.

Integrative Taxonomy Reveals a New Melitaea (Lepidoptera: Nymphalidae) Species Widely Distributed in the Iberian Peninsula

The Melitaea phoebe group is constituted by six species distributed throughout the Palearctic. One of the most widespread species is Melitaea ornata Christoph, 1893, present from France (Provence) to Central Asia. Recently, populations of M. ornata were discovered in a mountainous region of south-eastern Iberia, although doubts about their taxonomy existed. To clarify the taxonomic status of these populations and to revise the distribution of this taxon in Iberia, we have sequenced mitochondrial (COI barcode region) and nuclear (wg, RPS5, MDH, and EF-1α) markers, and analyzed the male genitalia for 72 Iberian individuals and for all the species of the M. phoebe group. This information was complemented with phenological and ecological data. Our results unveiled that the Iberian M. ornata-like taxon is in fact distributed through most of the Iberian Peninsula, except for the south-west and north-east. In contrast to the univoltine M. ornata, the Iberian taxon can be bivoltine in the wild. The Iberian taxon was retrieved to be related to M. ornata, but the differences in the genetic markers and genitalia were comparable to those found between species in the group. Based on the evidence here presented and according to species delimitation results, we propose to consider the Iberian taxon as a novel species, tentatively named Melitaea pseudornata Muñoz Sariot & Sánchez Mesa, 2019, stat. nov.Financial support for this research was provided by projects PID2019-107078GB-I00 funded by Ministerio de Ciencia e Innovación (MCIN)/Agencia Estatal de Investigación (AEI)/ 10.13039/501100011033 and 2017-SGR-991 funded by Generalitat de Catalunya to Roger Vila and by grant BES-2017-080641, funded by MCIN/AEI/10.13039/501100011033 and by ‘European Social Fund (ESF) Investing in your future’ to Joan C.

Reassessment of Poecilocampa navalagamellae Expósito, 2004 stat. nov. and its distribution in the Iberian Peninsula (Lepidoptera: Lasiocampidae, Poecilocampinae)

[EN]: Poecilocampa navalagamellae Expósito, 2004 stat. nov., endemic to Spain, is characterized and elevated to species rank. This taxon was originally described as a subspecies of Poecilocampa alpina (Frey & Wullschlegel, 1874) with insufficient diagnosis based on two male specimens only. Its southern populations are described as Poecilocampa navalagamellae turdetana ssp. nov. Notes on external morphology of the imago, genitalia, chorionic structure of the egg, habitat and host plant are presented herein, as well as ab ovo breeding results of P.n. turdetana. An actualised distribution map is provided. According to the results obtained from the study of mitochondrial DNA barcoding, P. navalagamellae belongs to a lineage well differentiated from the rest of the European Poecilocampa Stephens, 1828 taxa. It also differs from these in the wing pattern, the male genitalia, the chorionic structure of the egg and the larval external traits.[ES]: Se redescribe y se eleva al rango de especie Poecilocampa navalagamellae Expósito, 2004 stat. nov., endémica de España. Este taxón fue originalmente descrito de forma escueta como una subespecie de Poecilocampa alpina (Frey & Wullschlegel, 1874) en base a dos machos y sin el estudio de los genitalia. Sus poblaciones meridionales se describen como Poecilocampa navalagamellae turdetana ssp. nov. Se presentan también observaciones relativas a los adultos, genitalia, corion de los huevos, hábitat y plantas nutricias, así como los resultados de cría ab ovo de P. n. turdetana. Se proporciona un mapa de distribución actualizado. De acuerdo con los resultados obtenidos del estudio del ADN mitocondrial (código de barras genético), P. navalagamellae pertenece a un linaje bien diferenciado del resto de los taxones de Poecilocampa Stephens, 1828 europeos. También se distingue de ellos en el patrón alar, los genitalia masculinos, la estructura del corion del huevo y el aspecto de la larva
