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 ).
