Abstract
Nests of Synoeca septentrionalis were collected in two Brazilian Atlantic Rain Forest localities (Itabuna and Santa Terezinha, in the state of Bahia and Alfredo Chaves in the state of Espírito Santo). Synoeca septentrionalis was previously recorded only from Central America and northwestern South America. This findingextends its geographical distribution to Northeast and Southeast regions of Brazil, and represents the first record for Synoeca septentrionalis in the Brazilian Atlantic Rain forest, raising to three the number of Synoeca species known from Bahia State.
Highlights
Synoeca is a small genus of social wasps, with five species described, widely distributed in Central and South America (Richards 1978; Carpenter and Marques 2001)
Richards (1978: 181) reported similar nests features in S. septentrionalis collected in Cali (Colombia)
The nest collected in Santa Terezinha had eight females with clypeus entirely reddish, two females with clypeus reddish with a dorsal dark area, eight males with clypeus reddish with a triangular dorsal dark area, and five males with the clypeus reddish with a dark dorsal area
Summary
Synoeca is a small genus of social wasps, with five species described, widely distributed in Central and South America (Richards 1978; Carpenter and Marques 2001). Four species of Synoeca have been recorded in Brazil, S. septentrionalis was previously recorded only from North and Central America (Mexico, Guatemala, Belize, Honduras, El Salvador, Costa Rica, Nicaragua and Panama) and northwestern South America (Colombia, Venezuela, Ecuador, Peru and Bolivia) (Richards 1978; Andena et al 2009; Cely and Sarmiento 2011). Active nests of S. septentrionalis were discovered and collected in Atlantic Rain Forest in Itabuna (14°47'S, 39°16'W) and Santa Terezinha (12°46'S, 39°31'W), Bahia State, and in Alfredo Chaves (20°38'S, 40°45'W), Espírito Santo State.
