Type species — Lophopoeum carinatulum Bates, 1863 (subsequent designation, Thomson, 1864: 322 ). Scutelongus Gilmour, 1959a: 6 . Type species — Scutelongus freudei Gilmour, 1959 (original designation). Cristurges Gilmour, 1961: 364 . Syn. nov. Type species — Cristurges bimaculatus Gilmour, 1961 (original designation). Diagnosis. Lateral tubercle of the prothorax prominent, placed about middle; elytra with centrobasal crest pilose, rounded, without carinae. Number of species currently included: 15. Remarks. According to Gilmour (1961) on Cristurges : “Somewhat allied to the genus Lepturges Bates , from which the female is however immediately distinguishable through each elytron bearing a distinct setose centro-basal crest, the lateral pronotal spine is also stronger, more conical, placed nearer the middle of the side and more laterally directed.” These features do not allow the separation of Cristurges from Lophopoeum . In addition, the width of the prosternal and mesoventral process agrees with that of the Lophopoeum species. Accordingly, Cristurges is considered a junior synonym of Lophopoeum .
