Abstract

Edited by Marcelo Duarte -MZ/USPNeotropical Entomology 38 (6):786-790 (2009) Rhinoleucophenga joaquina sp. nov. (Diptera: Drosophilidae) da Região Neotropical RESUMO -O gênero Rhinoleucophenga Hendel compreende 18 espécies nominais e possui distribuição Neotropical e Neártica. Uma nova espécie foi encontrada em coleta realizada em Florianópolis, SC, e é descrita como Rhinoleucophenga joaquina sp. nov. Os espécimes encontrados emergiram de fl ores de Dyckia encholirioides (Bromeliaceae) coletadas em região de restinga sobre dunas. Este é o primeiro registro da utilização de fl ores como sítio de oviposição para Rhinoleucophenga.PALAVRAS-CHAVE: Taxonomia, nova espécie, Steganinae, Insecta, Brasil ABSTRACT -The genus Rhinoleucophenga Hendel comprises 18 nominal species and has a Neotropical and Nearctic distribution. A new species was found in a collection in Florianópolis, SC, Brazil, and is described as Rhinoleucophenga joaquina sp. nov. The specimens found were reared from fl owers of Dyckia encholirioides (Bromeliaceae), collected in a region of restinga on the dunes. The use of fl owers as breeding site for Rhinoleucophenga has never been reported before.

The flower flies and the unknown diversity of Drosophilidae (Diptera): a biodiversity inventory in the Brazilian fauna

“…The genus Rhinoleucophenga Hendel was represented by one species found in Florianópolis, still undescribed in the occasion. Based on the seven specimens caught, it was subsequently described as R. joaquina (Schmitz et al, 2009). Its life cycle is considerably longer than other drosophilids reported here, as imagines took 20-21 days to emerge after the field collection of the flowers.…”

Two New Species of the New World Genus Rhinoleucophenga (Diptera: Drosophilidae)

“…The following were examined: the holotypes of Rhinoleucophenga angustifrons Malogolowkin, 1946 ; R. lopesi , Rhinoleucophenga matogrossensis Malogolowkin, 1946 ; and Rhinoleucophenga nigrescens Malogolowkin, 1946 , as well as the type series of Rhinoleucophenga personata Malogolowkin, 1946 ; Rhinoleucophenga brasiliensis Costa Lima, 1950 ; Rhinoleucophenga capixabensis Culik and Ventura, 2009 ; Rhinoleucophenga fluminensis Costa Lima, 1950 ; and Rhinoleucophenga joaquina Schmitz et al . , 2009 .…”

“…Its species occur in the Neotropical and the Nearctic regions and are distributed from Argentina to the United States. The known biological information about Rhinoleucophenga is restricted to isolated characterizations of different habits, such as parasitism and predation from hemipteran agricultural pests ( Costa Lima 1950 , Culik and Ventura 2009 ) and one species’ emergence from the flowers of a bromeliad ( Schmitz et al . 2009 ).…”
