Differential Diagnosis. A rather coarsely granulate species ( Fig. 19), with prominent elongate granules linking the rather large elytral punctures; however, reliable determinations will be based on examination of the aedeagus. The aedeagus is relatively simple in this species ( Fig. 23). The median lobe is pointed apically, like that of E. simplex ( Fig. 37, 38). However, the parameres are very different in the two species, being pointed apically in E. inaequalis , and much longer than the median lobe.

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.69/0.82; head (width) 0.45; pronotum 0.61/0.55; elytra 1.11/0.82. Habitus and sculpture as illustrated ( Fig. 19). Head black, dorsum brown to reddish brown, venter and coxae dark brown, maxillary palpi testaceous. Eye with ca. 3–4 facets between canthus and posterior margin. Protibiae slightly arcuate. Granules of pronotum and elytral carinae quite coarse. Elytral punctures large, granules linking punctures prominent. Metaventral depression moderately deep, ca. six granules along base.

Etymology. Named in reference to the unequal lengths of the median lobe and parameres.

Distribution. Currently known only from Ecuador and Peru ( Fig. 129).
