following Linnavuouri, whose analysis in 1993 led him to believe that it was unnecessary to split the Phylini tribe based on the available evidence. Evidence was soon forthcoming from Menard and Schuh in 2011, where molecular and morphological evidence provided strong support for the monophyly of Leucophoropterini, so long as Tytthus, Karoocapsus and five other genera were grouped outside the tribe. In 2013 the Semiini tribe was resurrected and redefined by Menard, Schuh and Woolley, and Tytthus was placed with the Semiini.

Adults have shiny, broad, globose heads. The eyes have a yellow dot on the inside edge. In general, they have dark brown to black heads, a pronotum and scutellum, a pale translucent hemelytra, slender legs, and slender antennae. Tytthus resembles the genus Cyrtorhinus, and was previously considered to be a junior synonym. Ecology The members of Tytthus feed on the eggs of Delphacidae and a few on the eggs of other planthoppers. One of the early success stories of biological pest control was Frederick Muir's importation of Tytthus mundulus from Queensland, Australia to Hawaii to eat the eggs of Perkinsiella saccharicida that fed on the sugar cane crops.
