Revision of the Amazonian species of Syneches Walker (Diptera, Hybotidae, Hybotinae)

Abstract

A revision of the Amazonian species of Syneches Walker resulted in the re-description of four species and the description of nine new species: Syneches amazonicus sp. nov., S. angulatus sp. nov., S. applanatus sp. nov., S. bilobatus sp. nov., S. equatoriensis sp. nov., S. exilis sp. nov., S. maculosum sp. nov., S. striatus sp. nov., S. tenebricus sp. nov., and two new synonymies: S. quadricinctus (Fabricius, 1805) = S. curvipes (Fabricius, 1805) and S. hispidus Ale-Rocha & Vieira, 2008 = S. repletus Bezzi, 1909. The male of S. fuscescens Bezzi and the female of S. annulipes Bezzi are described and their terminalia are illustrated. Geographic records for S. annulipes Bezzi, S. curvipes (Fabricius), S. fuscescens Bezzi, S. manaos Smith, S. moraballi Smith, S. rafaeli Ale-Rocha & Vieira, S. repletus Bezzi and S. walkeri Smith and an identification key for the species recorded in the Amazon are provided.

Checklist of the dipterofauna (Insecta) from Roraima, Brazil, with special reference to the Brazilian Ecological Station of Maracá

“…The genus Baeodromia Cumming, 2006 currently includes only one Nearctic species, B. pleuritica(Melander, 1918), butCumming (2006) pointed out the existence of several undescribed Neotropical species, including in Brazil. Syneches moraballi Smith, 1963 is a widespread species in Brazil, with previous records for the entire Amazon basin, including IIha de Maracá(Menezes & Ale-Rocha, 2016). This is the only species of Syneches registered to the island.…”

New genus and first record of Hybotinae (Diptera: Empidoidea: Hybotidae) in middle Miocene Dominican amber

“…Neohybus is restricted to Neotropical Americas (Ale-Rocha & Rafael, 2004), whereas Euhybus has been recorded beyond the New World, but the definition of the genus needs to be re-examined (Sinclair & Cumming, 2017). Syneches is cosmopolitan in distribution and broadly dispersed with approximately 189 species described (Menezes & Ale-Rocha, 2016). Most species of Syneches occur in tropical regions.…”

“…Most species of Syneches occur in tropical regions. In America, the genus is widespread from southern Canada, to the south of Brazil and the Antilles (Wilder, 1974;Menezes & Ale-Rocha, 2016). The Hybotinae are predaceous flies living in various forest habitats, with adults capturing prey during flight (Sinclair & Cumming, 2017).…”
