“…Most characters were observed from dry pinned insects. Male genitalia were studied following Manfio et al (2013) , except for Amblycerus virens for which we followed Ribeiro-Costa (1998) . Colored images of the external morphology were captured with a LEICA DFC 500 digital camera attached to a LEICA MZ16 stereomicroscope, and subsequently processed using Auto-Montage Pro (Syncroscopy) image processing software of the “TAXon line- Rede Paranaense de Coleções Biológicas” at the Departamento de Zoologia, Universidade Federal do Paraná (UFPR).…”

Representatives of the subfamily Bruchinae (Coleoptera: Chrysomelidae) are usually small and inconspicuous, with only a few species drawing the attention. Here we deal with several unusually colored species of Amblycerus Thunberg, 1815, one of the two most diverse bruchine genera in the Western hemisphere. We define the virens group that consists of five species whose bodies are covered with a green vestiture, including one new for science, Amblycerus medialis Ribeiro-Costa, Vieira & Manfio, sp. n. (Type locality: Brazil: Pará, Rondônia). This study also provides redescriptions, diagnoses, comparative notes, illustrations, geographic distribution records and a key to the species in this group.

The search for and choice of oviposition sites are a key step in the life cycle of herbivorous insects. Theory predicts that natural selection should favor the discrimination ability of female insects to select between high- and low-quality oviposition sites. However, correlation between female preference and offspring performance is apparently lacking or even negative in some herbivore-plant systems. A possible explanation for this seeming failure is that most studies have focused on a single factor and spatial scale. Here, we investigated the preference-performance relationship in the seed beetle Gibbobruchus bergamini Manfio & Ribeiro-Costa (Coleoptera: Chrysomelidae). We took into account several potential factors affecting oviposition choices and larval survivorship through a multi-level approach. Hierarchical analysis that controlled for the non-independence of observations demonstrated that oviposition site choices were not related to the factors that most influenced larval survivorship. The apparent effects of other pod-feeding herbivores were greater at the plant and branch scales while at the pod level the most important factors were plant-related variables. Oviposition choices seemed to be time-constrained, meaning that females have little opportunity to further increase offspring performance through additional compensatory choices.

Phylogeny and evolution of the genus Ctenocolum Kingsolver & Whitehead (Coleoptera, Chrysomelidae, Bruchinae), with the description of three new species

The seed beetle genus Ctenocolum Kingsolver & Whitehead is peculiar because its preferred host Lonchocharpus Kunth (Fabaceae) is not preyed upon by other bruchine species. This study investigates the phylogenetic relationships and evolution of this genus and of its species groups, while providing the description of three new species and of the male of C. biolleyi Kingsolver & Whitehead. To infer phylogenetic relationships, a character matrix of 40 morphological characters was assembled and analysed using both parsimony and Bayesian inference. Ancestral state estimations of host plant use and biogeography analyses were also performed. A total of 22 species were examined: 16 Ctenocolum species (including the three new ones) and six outgroup bruchine species (from genera Caryedes Hummel, Meibomeus Bridwell, Pygiopachymerus Pic and Pachymerus Thunberg). All resulting trees support the monophyly of the genus Ctenocolum. Three synapomorphies characterize the genus: (i) head with frontal carina enlarged at base, (ii) male pygidium truncated apically, and (iii) lateral lobes of tegmen with dorsal process. The two known species groups are also recovered monophyletic in the parsimony analyses. The following three species are described: Ctenocolum inmaculatus Manfio & Ribeiro-Costa sp. nov. (Type locality: Venezuela, Guarico), which belongs to the group tuberculatum; Ctenocolum nigronotus Manfio & Ribeiro-Costa sp. nov. (Type locality: Porto Rico, Mayaguez) and C. pallidus Manfio & Ribeiro-Costa sp. nov. (Type locality: Republic of Guyana), which belong to the group podagricus. Finally, we present colored illustrations of dorsal patterns and male genitalia for these three new species and C. biolleyi in addition to an updated key for the genus Ctenocolum.
