Composition and structure of the fig wasp community in Amazonia

An understanding of the complex ecological interaction between fig wasps and their host plants in Amazonia requires previous knowledge of their distribution and diversity. The objective of this study was to describe the composition and structure of the wasp community associated with four species of Ficus in the municipal area of Manaus, Amazonas, Brazil. A total of 600 syconia from four species were collected. The study species were: Ficus obtusifolia Kunth; Ficus citrifolia Mill; F. americana subspecies guianensis Desv. form mathewsii; and F. americana subspecies guianensis Desv. form parkeriana. Statistical analyses were used to examine the relationship between fig wasp diversity and syconium diameter, and the effect of non-pollinating wasps on numbers of pollinators and seeds. Forty three species of fig wasp were identified, distributed across seven genera (Pegoscapus, Idarnes, Aepocerus, Physothorax, Anidarnes, Heterandrium , Eurytoma). Idarnes (carme group) was the wasps genus non-pollinator with greatest number of individuals with the greatest number of infested syconia (7409 wasps in 376 syconia). Analysing non-pollinating wasp diversity in relation to fig diameter, a significant difference was observed between the four fig species. Ficus citrifolia and F. americana subspecies guianensis form mathewsii had the smallest diameter but the greatest diversity of fig wasp. Ficus obtusifolia was the only species in which the non-pollinating wasps had a significant negative effect on the number of Pegoscapus sp. and on seed production.

Taxonomia da subfamília Corinninae (Araneae, Corinnidae) nas regiões neotropical e neártica

The subfamily Corinninae is characterized and diagnosed. Two synapomorphies are hypothesized for the subfamily, both regarding the male palpal reservoir, which is primarily coiled and presents a sclerotized distal sector. Seventeen genera are recognized, six of which are new: Abapeba (type species Corinna lacertosa Simon), Erendira (type species Corinna pallidoguttata Simon), Septentrinna (type species Corinna bicalcarata Simon), Simonestus (type species Diestus validus Simon), Tapixaua (type species T. callida sp. nov.) and Tupirinna (type species T. rosae sp. nov.). The genera Creugas Thorell, Falconina Brignoli and Paradiestus Mello-Leitão are revalidated. Diestus Simon and Lausus Simon are newly synonymized with Corinna C. L. Koch. Chemmis Simon is included in the synonymy of Megalostrata Karsch. Hypsinotus L. Koch is removed from the synonymy of Corinna and included in the synonymy of Creugas. Thirteen new species are described: Septentrinna yucatan and S. potosi from Mexico; Tupirinna rosae from Venezuela and Brazil; Tapixaua callida from Brazil and Peru; Abapeba hoeferi, A. rioclaro, A. taruma, Corinna ducke, C. colombo, C. mourai, C. recurva and Parachemmis manauara from Brazil; Creugas lisei from Brazil, Argentina and Uruguay. Twenty seven species are redescribed.

Feeding ecology in the small neotropical amphisbaenid Amphisbaena munoai (Amphisbaenidae) in southern Brazil

We analyzed the alimentary tract of 66 specimens of Amphisbaena munoai Klappenbach, 1969 from the Serra do Sudeste, state of Rio Grande do Sul, southern Brazil. Forty specimens (60.6%) had prey items in their gut. The diet consisted mainly of small invertebrate prey, such as termites, insect larvae and ants. The most abundant prey item was termites, found in 62.5% of the non empty stomachs. The high number of individual prey items in the majority of stomachs, the small size of the regular prey items, and the absence of gut content in specimens of A. munoai kept alive for about two days, indicate that this species forages very frequently. The predominance of fossorial prey items and the occasional records of nomadic ants lead us to suggest that A. munoai usually feeds underground, and occasionally forages on the surface.
