Among the genera of Urosyristini, Curvicephus is most similar to Sinicephus Maa, 1949 as shown by the head not elongated backwards, the head and mesopleuron rugose, abdomen narrow and slender, malar space broader than diameter of lateral ocellus and the first terga not distinctly incised. However, Sinicephus differs from Curvicephus by the middle tibia with 1 preapical spur, the lateral ocelli distinctly behind the line of posterior margin of eyes, the distance between toruli broader than distance between torulus and inner orbit, the claw with the inner tooth shorter than apical tooth, the antennomere 3 clearly longer than antennomere 4, the ovipositor sheath not curved upwards, the lancet with basal annuli strongly condensed and the apical serrulae not bifurcate.</p><p>Among known genera of Cephidae, only this genus has the lateral ocelli behind the line of posterior margin of eyes in dorsal view.</p><p>Key to the species of Curvicephus gen. nov.</p><p>1.
