Re-examination of the genus-level taxonomy of the pollen beetle subfamily Meligethinae – Part 1. Sagittogethes Audisio & Cline 2009 and allied genera; with description of a new genus (Coleoptera: Nitidulidae)

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,

Palms and pollen beetles: two new anthophilous beetle species of Meligethinus from Mozambique (Coleoptera: Nitidulidae: Meligethinae)

The genus Meligethinus Grouvelle, 1906 represents a small group of pollen beetles, including some twenty species
distributed from southern Palaearctic areas to northern Oriental and Afrotropical regions. All constituent species appear to
be strictly associated as larvae and adults to male inflorescences of palms (Monocots: Arecaceae). Two new species of this
genus (Meligethinus mondlanei sp. nov. and M. hamerlae sp. nov.) were recently discovered in southern Mozambique,

New and poorly known Meligethes Stephens from China, with bionomical data on some species (Coleoptera: Nitidulidae: Meligethinae)

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.

Two new Lamiogethes Audisio & Cline from China (Coleoptera: Nitidulidae, Meligethinae)

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.
