Shannoniella Townsend, 1939: 249 . Type species: S. cuspidata Townsend, 1939: 251 , by original designation.

Diagnosis. In addition to the characters included in the key of Mulieri et al. (2010), the following features also characterize and can help to distinguish Shannoniella from the other rhinophorid genera: head shape strongly modified especially in the males, with sunken face and vibrissal angles conspicuously projected forward and turned inwards apically (Figs 1b, 2b); male proclinate orbital setae present; male first aristomere elongated and more than twice as long as its greatest diameter; metathoracic spiracular lappets practically absent; vein R1 entirely setulose dorsally; wing infuscated but with 3 or 4 clear (non-infuscated), hyaline spots on cells r2+3, r4+5, dm and m (hyaline spot on r2+3 absent in S. setinervis sp. nov.); male tergite 6 divided into two hemitergites.
Remarks. Neotropical genera of Rhinophoridae can be identified using the keys provided by Pape (2010, with Apomorphyto Cerretti, Lo Giudice & Pape 2014 included as “Undescribed Genus A”) and Mulieri et al. (2010), with the complement added by Nihei & Andrade (2014) to fit the new redefinition of Trypetidomima .
