 pt REGISTRO DE NOVAS ESPÉCIES DE FORMIGAS (HYMENOPTERA: FORMICIDAE) NO ESTADO DO RIO GRANDE DO SUL
Fleck, Marciane Danniela; Cantarelli, Edison Bisognin & Granzotto, Fabiane

Resumo

O presente trabalho objetivou registrar a ocorrência de novas espécies de formigas para o estado do Rio Grande do Sul e, com isso, contribuir para o conhecimento sobre a mirmecofauna. As coletas foram realizadas em quatro ambientes (floresta nativa, plantio de eucalipto, plantio agrícola e pastagem exótica). Para a coleta das formigas, foi utilizado o método do extrator de mini-Winkler, cujo processo consistiu em retirar 1m² de serapilheira, peneirá-la e acondicioná-la em extratores de mini-Winkler para a obtenção da fauna. Foram coletadas 108 espécies, representantes de 31 gêneros, 18 tribos e oito subfamílias. Destas, a floresta nativa, apresentou 90 espécies coletadas, seguida pelo plantio de eucalipto, com 65 espécies, pelo plantio agrícola e pela pastagem exótica, com 20 espécies cada. Neste trabalho, é feito o primeiro registro de ocorrência de Dorymyrmex thoracicus check for this species in other resources (Dolichoderinae), Camponotus arboreus check for this species in other resources , Camponotus melanoticus check for this species in other resources (Formicinae), Apterostigma madidiense check for this species in other resources , Apterostigma sp. complexo pilosum check for this species in other resources , Cyphomyrmex major check for this species in other resources , Cyphomyrmex vorticis check for this species in other resources , Wasmannia rochai check for this species in other resources , Cephalotes pusillus check for this species in other resources , Strumigenys (Pyramica) rugithorax check for this species in other resources , Strumigenys cosmotela check for this species in other resources , Strumigenys silvestrii check for this species in other resources , Pheidole aper check for this species in other resources , Pheidole heyeri, Pheidole rugatula, Pheidole siggilata, Pheidole senilis, Pheidole sospes, Megalomyrmex pusillus check for this species in other resources (Myrmicinae) e Pachycondyla ferruginea check for this species in other resources (Ponerinae) para o Rio Grande do Sul

Abstract

This study aimed to report the registration of new ant species in Rio Grande do Sul state and thus to contribute to the knowledge about the ant fauna (Myrmecofauna). Collections were made in four different environments, namely, native forest, eucalyptus plantations, agricultural plantation and exotic pasture. We used the mini-Winkler method of extraction to collect the ants. We removed 1 square meter (1m²) of litter, sifted it and packed it in mini-Winkler extractors to obtain the fauna. We collected 108 species, which represent 31 genera, 18 tribes and 8 subfamilies. The native forest presented 90 collected species, the eucalyptus plantation presented 65 species, and the agricultural plantation and the exotic pasture presented 20 species each. We have registered for the first time the following species in the state of Rio Grande do Sul: Dorymyrmex thoracicus check for this species in other resources (Dolichoderinae), Camponotus arboreus check for this species in other resources , Camponotus melanoticus check for this species in other resources (Formicinae), Apterostigma madidiense check for this species in other resources , Apterostigma sp. pilosum check for this species in other resources complex, Cyphomyrmex major check for this species in other resources , Cyphomyrmex vorticis check for this species in other resources , Wasmannia rochai check for this species in other resources , Cephalotes pusillus check for this species in other resources , Strumigenys (Pyramica) rugithorax check for this species in other resources , Strumigenys cosmotela check for this species in other resources , Strumigenys silvestrii check for this species in other resources , Pheidole aper check for this species in other resources , Pheidole heyeri, Pheidole rugatula, Pheidole siggilata, Pheidole senilis, Pheidole sospes, Megalomyrmex pusillus check for this species in other resources (Myrmicinae) and Pachycondyla ferruginea check for this species in other resources .
