A REVISION OF NEOSILBA McALPINE WITH A KEY TO THE WORLD GENERA OF LONCHAEIDAE (DIPTERA)

Abstract

AbstractThe identities of the 12 previously described species of Neosilba McAlpine, seven of which are represented among the syntypes of pendula (Bezzi), are established: batesi (Curran), certa (Walker), dimidiata (Curran), fuscipennis (Curran), glaberrima (Wiedemann), longicerata (Hennig), major (Malloch) [(= magna (Hennig), new synonymy], parva (Hennig), pendula (Bezzi), perezi (Romero S. and Ruppel), and pseudopendula (Korytkowski and Ojeda). Three new species, also represented among the syntypes of pendula, are described: oaxacana and peltae from Mexico, and zadolicha from Colombia and Brazil. Lectotypes are designated for magna, parva, pendula, and perezi. “Carpolonchaea” devions Hennig is placed in Silba Macquart, and “Carpolonchaea” intermedia Hennig is transferred to Lonchaea Fallen (new combination). New keys to the world genera of Lonchaeidae and to all described species of Neosilba are provided. Fifty-four illustrations, mostly of male and female terminalia, are given.
