The leaf-beetle genus Microdonacia Blackburn (Coleoptera: Chrysomelidae: Galerucinae): revision and systematic placement

Abstract. The genus Microdonacia Blackburn is revised and its systematic position considered. Ten species are treated, seven of which are new ( bidentata, eucryphiae, grevitteae, incurva, octodentata, pilosa, pomaderris ), and lectotypes are designated for two species. Four of the new species are placed in Tantawangalo subgen.n. Microdonacia is compared with the genera Cassena Weise, Licyllus Jacoby and Orthaltica Crotch. The sister-group for Microdonacia is identified as Orthaltica and these genera are placed incertae sedis in the Galerucinae, as used in the sense of Crowson (1967). The proposed phylogeny of the species is illustrated on a cladogram.

Chromosomes of sixteen European species ofLongitarsus flea-beetles (Coleoptera,Chrysomelidae)

Sixteen species ofLongitarsus have been chromosomally surveyed, showing a continuous range of even numbers from 2n=26 to 2n=32 chromosomes. Among the total of twenty-three known species, about 40% display a 14+Xy male karyotypic formula, the possible modal and most primitive one for the genus. The current taxonomy of species groupings is in good agreement with the chromosome numbers in some cases, but not in others. Also, there is no interrelationship between chromosome numbers and foodplant selection. The number of large bivalents at metaphase I is generally negatively correlated with the diploid value, suggesting the possible role of centric fusions coupled to shifts in the amount of chromatin as the main chromosomal changes in the evolution ofLongitarsus. The karyotypes of a few studied species are composed of metacentric chromosomes, some of them of rather large size, and a minute y-chromosome. A possible example of polymorphism for the chromosome number inL. nigrofasciatus is reported and briefly discussed.     

A worldwide species catalogue and key of Sermyloides (Coleoptera,Chrysomelidae, Galerucinae) with description of two new species from China

In this study, a species catalogue of Sermyloides, including 42 species, is given. Two new species are described: Sermyloides wuyiensis sp. nov. from Fujian, China and Sermyloides bipunctatus sp. nov. from Chongqing, China. A key to species, photographs of aedeagus, habitus of new species and habitus of 14 species of Chinese holotypes are provided.www.zoobank.org/urn:lsid:zoobank.org:pub:820BDA9F-633B-49D8-B5F0-45610E622C9A.     

Chromosomal analysis of Leptinotarsa and Labidomera species (Coleoptera: Chrysomelidae)

Chromosomes were examined from 13 Leptinotarsa species: L. decemlineata, L. texana, L. defecta, L. juncta, L. rubiginosa, L. haldemani, L. tumamoca, L. peninsularis, L. behrensi, L. heydeni, L. lineolata, L. typographica, and L. undecimlineata. With the exception of L. undecimlineata, which has 2n=32+XO, all other species have the basic chromosome number 2n=34+XO. Of two Labidomera species also examined, L. clivicollis has 2n=32+XO and L. suturella has 2n=30+XO. Idiograms showed that the majority of the autosomes are submetacentric. All species have a large submetacentric X chromosome. Meiotic pairings were regular with both closed and open bivalents. Chiasma frequencies varied considerably among species and even between populations. No distinct correlation was evident when chromosome numbers and chiasma frequencies were compared with host plant association and geographic distribution patterns of Leptinotarsa species.     

New genera and new species of leaf beetles (Coleoptera: Polyphaga: Chrysomelidae) from Lowermost Eocene French amber

Short reviews of known fossil records of the mentioned subfamilies are given and position of the new genera discussed.

A new species of the genus Phygasia (Coleoptera: Chrysomelidae: Alticinae) from Taiwan of China

Continuing study on the Chinese species of Phygasia Chevrolat, 1836 revealed 10 specimens collected from Taiwan that were distinctly different from other described species within this genus. The new species is similar to P. ornata Baly, 1876 and P. pseudornata Wang et Yang, 2008, but can be distinguished from them by the color and position of elytra markings as well as the shape of male genitalia: the black markings on the elytra only covered the humeral area and the sub-apical area of elytra, and genitalia of male pointed and short with big basal opening. A new species, Phygasia taiwanensis sp. n., is described herein.
