A female of Schuhacantha bifurcata gen. n. et sp. n. (Hemiptera: Heteroptera: Colobathristidae: Colobathristinae) is described from continental Malaysia (Pahang). The autapomorphies of the genus are a robust bifurcate process situated at the middle lobe of the pronotum and an extremely short labium; a potential synapomorphy with Centromus Bergroth, 1910 is a strongly protruding, bill-shaped ovipositor. The first key to Eastern Hemisphere genera of the Colobathristidae which are distinct from the Neotropical fauna is provided. Morphology as well as diagnostic and functional significance of some structures (antennal sclerite, pronotal process, evaporatorial system, abdominal laterotergites, forewing venation, femoral spine, female terminalia) are discussed.
