A new species of Brachygasterina Macquart from Chile (Diptera: Muscidae)

Abstract

. Brachygasterina maculata, new species, from Santiago, Chile, is here described and illustrated, and its position in the genus Brachygasterina is discussed.

New species of Brachygasterina Macquart (Diptera: Muscidae) from high altitudes of Colombia, Ecuador and Venezuela

“…Here we present a new diagnosis of Brachygasterina to include the discussion of the characters of the three new species, despite the recent revision of the genus (Carvalho & Pont 2006) and the diagnosis (Couri et al 2007). …”

“…The monophyly of Brachygasterina is not well established since Couri et al (2007) placed B. maculata outside of Brachygasterina clade, using the data matrix of Soares & Carvalho (2005 General color. General body coloration metallic blue to bluish-purple, metallic green in alcohol.…”

“…The generic concept of Brachygasterina was enlarged to include B. maculata, since this Chilean species has characters that disagreed with the earlier Brachygasterina concept (Couri et al 2007): palpus not dilated, absence of interfrontal seta and katepisternals 2:2.…”

“…Based on the most recent Brachygasterina concept (Couri et al 2007), herein we describe three new species of the genus from high altitudes of Ecuador, Colombia and Venezuela, with a key to the ten current species of Brachygasterina.…”
