Type species. Dioxippe (Tmethypocoelis) ceratophora Koelbel, 1897, by original designation, subsequently elevated to generic status by Shen (1935) ; gender feminine. Remarks. The genus name Dioxippe de Man 1888, to which the type species was originally placed, is pre-occupied by Dioxippe Thomson, 1860 [ Coleoptera ]; and therefore, a replacement name, Tympanomerus , was proposed by Rathbun (1897) , and subsequently used by Tesch (1918) in his account of Tympanomerus ceratophora . However, Tympanomerus Rathbun, 1897, is itself currently considered a junior synonym of Ilyoplax Stimpson, 1858. Shen (1935) was the first to formally elevate Tmethypocoelis to full generic rank. The year of publication of Tmethypocoelis ceratophora has usually been wrongly attributed to Koelbel (1898) ; the 1898 paper is actually a German translation of Koelbel's original paper published in 1897 in Hungarian. The name should thus be cited as Tmethypocoelis ceratophora (Koelbel, 1897).
