—Laselva, n. gen, and Laselva triplehorni, n. sp., are described and illustrated from the canopy of a lowland Atlantic rainforest in Costa Rica. The genus belongs to the ‘‘Sphaeronychini’’ of the Alticinae.

Complex morphological or functional traits are frequently considered evolutionarily unique and hence useful for taxonomic classification. Flea beetles (Alticinae) are characterized by an extraordinary jumping apparatus in the usually greatly expanded femur of their hind legs that separates them from the related Galerucinae. Here, we examine the evolution of this trait using phylogenetic analysi...

Examination of the metafemoral spring in a variety of Neotropical genera was undertaken th order to further the study of this internal generic level charac ter and to relate some Neotropical genera to the previously established metafemoral spring morpho-groups of Palearctic and Nearctic genera. Although this study concerns only a portion 91 of the more than 220 genera of Neotropical Alticinae, ...

an account of the iranian alticine fauna, comprising 59 species from 11 genera, is presented. phyllotreta muehlei sp. nov. is newly described and 13 species are recorded for the first time from iran.

Two new species of Laboulbeniales are described: Laboulbenia parasyphraeae, parasitic on Parasyphraea sp. (Coleoptera, Chrysomelidae, Alticinae), and L. skelleyi, parasitic on Pselaphacus rubricatus and P. signatus (Coleoptera, Erotylidae). Other recorded species are Chaetomyces pinophili, Chitonomyces aurantiacus, Corethromyces ophitis, Dimorphomyces platensis, Dioicomyces anthici, D. cf. noto...

A so-called R-gene renders the yellow-striped flea beetle Phyllotreta nemorum L. (Coleoptera: Chrysomelidae: Alticinae) resistant to the defenses of the yellow rocket Barbarea vulgaris R.Br. (Brassicacea) and enables it to use it as a host plant in Denmark. In this study, genetic markers for an autosomal R-gene, inherited as a single, dominant locus in flea beetles from the Danish locality "Kva...

four species of flea beetles (col.: chrysomelidae, alticinae), viz. altica tsharynensis (ogloblin), aphthona pygmaea (kutschera), longitarsus pulmonariae weise and neocrepidodera interpunctata (motschulsky), collected from the south of caspian sea are newly recorded from iran. host plants, localities and diagnostic characters of each species are given.

This is a preliminary study of the diversity of the Flea Beetles (Alticinae) of the Mexican state of Oaxaca based on fieldwork by the author in 1991, 1997, and 2010, the literature, and specimens in several institutional collections. The number of genera and species for Mexico as well as for Oaxaca increased significantly from previous studies. There are now 625 species in 90 genera recorded fr...

I investigated the phylogenetic relationships within the New World Blepharida and among related genera, using sequences of the Internal Transcriber Spacer 2 (ITS2) of nuclear ribosomal DNA and sequences of the COI and COII genes of the mitochondrial genome. Cladistic analyses were performed using parsimony, maximum likelihood, and Bayesian methods. These methods generated almost identical topol...
