A remarkable new genus of Iberian troglobitic Trechodina (Coleoptera: Carabidae: Trechinae: Trechini), with a revisited molecular phylogeny of the subtribe

Abstract: A new representative of the subtribe Trechodina, Iberotrechodes spinosus n. gen., n. sp., subterranean and known so far from a single cave system of the Cantabrian chain (NW Spain), is described. The external morphology of the new species is highly derived within Trechodina, in particular for the peculiar and unique shape of its elytra, and likely due in part to its subterranean habits. A phylogenetic analysis based on six nuclear and mitochondrial genes placed it unambiguously within the subtribe Trechodina o… Show more

“…n. and Argonotrechus subgen. n. This suggests an eastern origin of the whole Pyrenean lineage, an assumption also supported by the complete absence of the group in the Cantabrian chain, which is inhabited by other old lineages related to Trechus sensu lato (the Apoduvalius clade), is known to have acted as a refugium in the past, and hosts remarkable paleoendemic Trechini ground beetles such as Iberotrechus and Iberotrechodes ( Jeannel 1913; Faille et al 2021).…”

“…Subterranean environments host some of the less known parts of beetle diversity in the Western Palearctic and remain among the most important reservoirs of unknown biodiversity for the area, as evidenced by recent discoveries (e.g., Fresneda et al 2009; Casale et al 2012; GuÉorguiev 2012; Faille et al 2015a; Njunjic et al 2016; OrtuÑo et al 2017; HlavÁČ et al 2019; Lohaj & Delić 2019; Maghradze et al 2019; Ribera & Reboleira 2019; Faille et al 2021; Piva 2021; Casale et al 2022; F Aille & Bourdeau 2022a, 2022b). The species colonizing the hypogean environment share some remarkable morphological features known as troglomorphies: depigmentation, apter-ism, lack of eyes and elongation of appendages ( Vandel 1964; Barr 1968).…”
