“…Diagnosis. The genus Tillicera is closely related to Hemitrachys Gorham but differs from it by the following characteristics (Yang and Yang 2013;Gerstmeier and Stapel 2016): antennomeres V-XI not clubbed; elytral length to width ratio 2.01-2.37; pulvillar formula 4-4-2, 4-4-3 or 4-4-4 (Hemitrachys: antennomeres V-XI clubbed; elytral length to width ratio 1.58-1.80; pulvillar formula 4-2-2).…”

“…nov., Tillicera spinosa sp. nov., and Hemitrachys tubericollis Yang & Yang, 2013 for the first time 34,35). The genus Tillicera is included in the Tillicera genus group with Apopempsis, Cardiostichus, Hemitrachys, Placocerus, and Plathanocera (Gerstmeier and Stapel 2016); the monophyly of the genus group, however, is questioned by Bartlett (2021).…”
