Diagnosis

Embidobia dooranetra sp. nov. is close to E. brittanica but differs from it in having an elongate OOL, at least 1.3 × the diameter of the median ocellus; striae on T1 and T2 are elongate, extending>0.8 × length of the tergite. Whereas in E. brittanica OOL is subequal to diameter of median ocellus and T1 and T2 are striate only at base.

Etymology

The Sanskrit epithet ‘dooranetra’ means ‘eyes set far apart’, referring to the placement of the lateral ocelli, which are present far from the orbits. The name is treated as an adjective.
