Brassicogethes salvan (Audisio et al. Insect Systematics and Evolution, 34, 121) is certainly among the most important and unexpected recent discoveries in the European beetle fauna. The species was initially described from a couple of unidentified specimens collected in 1912 on the Maritime Alps (NW Italy). Despite a long series of attempts to recollect the species at the type locality (Rovina Lake, Mount Argentera Massif, Cuneo Province, Piedmont, NW Italy) and several neighbouring areas of the SW Alps between 2002 and 2016, no specimens of this species were found. We re‐discovered B. salvan in a small high valley of the Regional Natural Park of the Maritime Alps, a few dozen kilometers from the type locality. The previously unknown larval host‐plant as Descurainia tanacetifolia (L.) Rchb., Brassicaceae was determined. Some unusual life history traits were also observed. In an effort to yield a suitable taxonomic placement for this species, we present a partial preliminary molecular phylogeny for this species and related taxa. A discussion regarding some issues about its actual and potential geographic distribution in southern France and northwestern Italy is also provided. We propose an EN (Endangered) classification for this species following the IUCN criteria, and discuss aspects of its rather problematic conservation biology.

“…The new species is a member of a clade (the Meligethes chinensis Kirejtshuk, 1979 species group). An integrative taxonomy approach (see, e.g., Audisio et al 1999, 2000, 2001a, 2001b, 2002, 2006, 2011, 2012, De Biase et al 2003Mancini et al 2016) is needed to fully illuminate the relationships involving the constituent species (all from China and neighboring countries: Figs 4-5) thus far included in this problematic group. Eleven of the species (M. chinensis, M. scrobescens, M. bourdilloni Easton, 1968, M. henan Audisio, Sabatelli & Jelínek, 2015, M. pseudochinensis Audisio, Sabatelli & Jelínek, 2015 inexpectatus sp.…”

Meligethes (Odontogethes) inexpectatus sp. n. is described from China, Sichuan Province. The new species is based on a female specimen previously incorrectly referred to as Meligethes scrobescens Chen, Lin, Huang & Yang, 2015, which was recently described from a series of male specimens collected in the same area. Both species belong to the taxonomically difficult species-group related to M. chinensis Kirejtshuk, 1979, including a dozen closely related species distributed throughout Nepal and SW and Central China. The true female of Meligethes scrobescens is also described, based on recently collected material from China (Hubei and Chongqing), including a series of male and female specimens. Diagnostic characters distinguishing the new species from all other known members of the M. chine nsis species-group and species-complex are discussed, and their overall range distribution are depicted. Additional data on geographic distribution and larval ecology of some of the closely related species are also reported.

“…As reported in our Meligethes revision [7], and in more recent papers [8][9][10] Despite the incomplete taxonomic and biogeographic coverage, the present morphological phylogenetic analysis and the thus far available molecular data seem to support at least the following conclusions: 1) Based on molecular evidence, the Meligethes complex of genera univocally represents a monophyletic lineage, including almost certainly three species-rich genera or subgenera (Meligethes s.str., Odonthogethes, and Brassicogethes), which are comparable in the number of inclusive species (32, 31 and 42 species, respectively). Other preliminary molecular data using mitochondrial and nuclear markers (COI, NADH, ITS2, PEPCK) [24,26], suggested that the genus Meligethinus Grouvelle (a small, mostly Oriental and Afrotropical genus including some 20 species associated as larvae with male in orescences of Arecaceae [1,46]) is placed as sister of this clade. In fact, the phylogenetic position of Meligethes and Odonthogethes is certainly closer to both Brassicogethes and Meligethinus, than to any other recognized genera inside Meligethinae [46].…”

“…The thus far available molecular data set for Meligethes and Brassicogethes, including sequences of three mitochondrial and nuclear genes for 21 species (Table 2), allowed us to depict a rst scenario of the phylogeny of Meligethes and of some related genera, to also provide a framework for understanding the origin of this group of Meligethinae, its evolution on different subfamilies of Rosaceae, and the shift of the rst ancestral Brassicogethes to Brassicaceae. Although the genus Meligethes has been included in previous phylogenetic studies, those were aimed to resolve suprageneric classi cation using molecular approaches [24][25][26] (Figs. 1A (a), (b), (c); 7) complete absence of circumocular furrows ("occipital sulci") when viewed dorsally (Figs.…”

Background: Meligethes are pollen-beetles associated with flowers of Rosaceae as larvae. This genus, in its present-day concept, consists of 63 known species in two subgenera, Meligethes and Odonthogethes, predominantly occurring in the eastern Palaearctic. We analyzed 61 morphological and ecological characters (128 states) of all species, as well as of 7 outgroup species from 7 Meligethinae genera (including the believed sister-genus Brassicogethes), to investigate their phylogeny. A parallel molecular analysis was carried out on 9 Meligethes, 9 Odonthogethes, 3 Brassicogethes and 2 Meligethinus species, based on DNA sequence data from mitochondrial (COI, 16S) and nuclear (CAD) genes, to obtain additional phylogenetic information on the group. Results: Morphological phylogenetic reconstructions supported the monophyly of the genus, and clades corresponding to purported subgenera Meligethes and Odonthogethes. Main species-groups were mostly recovered intact, however some unresolved polytomies remained. Molecular data suggested a different scenario, placing members of Brassicogethes (including 42 mostly W Palearctic species associated with Brassicaceae) as sister to Odonthogethes, with this clade being sister to Meligethes s.str. This alternative phylogenetic assessment suggests that the monophyletic clades Meligethes s.str., Odonthogethes and Brassicogethes should be regarded alternatively as three subgenera of a monophyletic Meligethes, or three genera in a monophyletic genus-complex, with mutually monophyletic Brassicogethes and Odonthogethes. Molecular analyses estimated the origin of this lineage at ca. 14-15 Mya from a common stem including Meligethinus. Conclusions: We hypothesize in the Middle Miocene (likely in Langhian Age), the first Meligethes specialized on Rosaceae, on which they subsequently radiated during Late Miocene and Plio-Pleistocene. This radiation was enforced by geographic isolation in E Asiatic mountain systems, and by larval host-plant specialization. Combined evidence from morphology, ancestral state parsimony reconstruction of host-plant associations, and molecular evidence, suggested that for Meligethes s.str., Rosoideae (Rosa spp.) represented the ancestral hosts, followed by an independent shift of ancestral Odonthogethes (ca. 9-15 Mya) on Rubus (Rosoideae) and members of Rosaceae Spiraeoideae. Other ancestral Odonthogethes probably shifted again on the unrelated plant family Brassicaceae (maybe 8-14 Mya in S China), allowing a rapid westward radiation of the Brassicogethes clade.
