First records of the new species (and new genus) Lourdesiella falcatum (Lepidoptera: Stathmopodidae, Gelechioidea) in southwestern Iberian Peninsula (Spain)

Study Extent

This study was carried out on a 0.5 ha plot located at the bottom of a valley called Barranco de Carabaña, within the Sierra de Aracena y Picos de Aroche Natural Park. It has an altitude of 600 m above sea level, a north-north-west orientation and an average slope of 20 %. Within the boundaries of the plot there are four different habitats: chestnut woodland (Habitat of Community Interest 9260-Castanea sativa woodland), an orchard, hedgerows on the boundaries and a gallery woodland in the northern area. The predominant tree species surrounding the plot belong to the genus Quercus, in order of importance, Q. suber L., Q. faginea Lam. and Q. rotundifolia Lam.

Sampling

In June 2020 and 2021, daytime transects through the different habitats that make up the study area (orchard, chestnut grove, gallery forest and hedgerows) with a length of about 250 m, following, in general, the methodology described by Pollard & Yate (1993).

Quality Control

In addition to comparing the morphological elements of the captured specimens, at all stages of development, including the genitalia, the proposed tool for molecular identification of Lepidoptera species, or DNA barcode marker, which uses the nucleotide sequences of the mitochondrial molecular marker cytochrome oxidase I (COI) (Hebert et al. 2003), has also been used (Hebert et al. 2003).
