? Tetraconcha sp.

[A] CH 5008 ♀ photo only

After taking photos the specimen was eaten by ants and only parts of the tegmina remained. From coloration, tegmen shape and its short ovipositor, it ( Fig. 1 H) looks similar to T. banzyvilliana , whereas according to the pictures presented in OSF T. fenestrata , stichyrata (tegmen shape) and smaragdina (coloration) can certainly be excluded.

Focusing on the short ovipositor, even the tribe Phlaurocentrini Karsch, 1889 with Phlaurocentrum , Buettneria and Leiodontocercus may be possible. Only using the keys in Brunner von Wattenwyl (1891) and Chopard (1955), it is difficult or impossible to determine Tetraconcha by females, because one has first to decide that the ovipositor is (nearly always; Chopard 1955) longer than the pronotum (incorrect) and in a second step that it is shorter.
