Diagnosis

Erythrocricus electrofasciatus resembles E. sanguineostriatus in the characteristics cited above for the diagnosis of E. sanguineostriatus but differs by the general coloration (Fig. 4) and by the transverse red line only on the posterior metazonites. Coxae of leg pair 3 with a pointed apex (Fig. 4B); the telopodite of the anterior gonopod is well developed in posterior view (Fig. 5B), the external branch of the posterior gonopod lamellated and narrow, distally long and slender (Fig. 5C).
