Etymology. The specific name “ occiputalis ” which comes from the Latin words “occiput” refers to the presence of occipital carina.
Comments. This new species O. occiputalis sp. nov. can be distinguished from other species by having occipital carina present (Fig. 7b), dorsal pronotal area papillate and first median cell of forewing right triangular (Fig. 7g).
