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.

The 24 members of the Euro-Asiatic genus Thymogethes are highly specialized pollen beetles associated as larvae with flowers of Lamiaceae Nepetoideae. All members of the genus were analyzed in within the framework of an integrative taxonomy approach, which was aimed to reconstruct the phylogenetic relationships, as well as the possible pattern of evolution of their larval-host-plant association.

Recent molecular and morphological data derived from members of the pollen-beetle subfamily Meligethinae suggest the need to separate
the genus Sagittogethes Audisio & Cline, 2009, including species mostly distributed in Western Palaearctic areas, into two distinct
(although related) genera, Sagittogethes and Teucriogethes gen. n. This new genus, comprising the Western European Meligethes obscurus
Erichson, 1845 as its type species, includes less than ten species distributed between the Iberian Peninsula and North Africa westward,

Five new species of the genus Lamiogethes Audisio & Cline are described from western, central and southern China: L.
falcatus sp. n. (Sichuan), L. hastipenis sp. n. (Hubei), L. sagittalis sp. n. (Shaanxi), L. unditibiis sp. n. (Chongqing), and
L. limaelytralis sp. n. (Sichuan). The first four new species appear to be morphologically related to Lamiogethes ancestor
(Kirejtshuk, 1980) (comb. n.) from Central China, and allied taxa. Lamiogethes limaelytralis sp. n. appears to be more

Meligethes (Odonthogethes) trapezithorax sp. n., M. (O.) tricuspidatus sp. n., and M. (O.) luteomaculatus sp. n. are described from Hubei Province, China, based on a series of recently collected specimens. The new species appear morphologically closely related to M. (O.) brassicogethoides Audisio, Sabatelli Jelínek, 2015 from Yunnan [M. (O.) trapezithorax sp. n.], M. (O.) occultus Audisio, Sabatelli Jelínek, 2015 from Yunnan [M. (O.) tricuspidatus sp. n.], as well as M. (O.) pallidoelytrorum Chen Kirejtshuk, 2013 from Sichuan and M.

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.

Two new species of the genus Lamiogethes Audisio & Cline, 2009are described from China (Sichuan): L.forcipenissp. n.,and L.con-vexistrigosussp. n., based on a series of recently collected specimens. The new species are both likely morphologically related to L.po-tanini (Kirejtshuk, 1979) from Sichuan and to L. conjungens (Grouvelle, 1910) from Yunnan. These new species clearly differ from their related taxa by details of the body shape and color, and the distinct shape of the male and female genitalia.
