Justification of synonymy

Schubart (1962) described two species, Erythrocricus sanguineostriatus and E. miniatostriatus , both similar in body pattern and gonopods structure. Despite the similarities, both species present variations in

the red coloration on body rings wich in E. sanguineostriatus is present dorsally and in E. miniatostriatus dorsally and ventrolaterally. Our examination of the type species revealed that there is no significant difference either in external morphology or the structure of the gonopods between the species. Still, during examination of fresh specimens, we observed that the differences in the red coloration, seems to reflect only intraspecific variation.


Erythrocricus sanguineostriatus ( Schubart, 1962) resembles E. electrofasciatus ( Schubart, 1957) comb. nov. by the shape of the anterior gonopod ( Figs 2A View Fig , 5A View Fig ) with a triangular sternite having the medial portion distally rounded and the anterior gonopod wider than long but differs by the telopodite of the anterior gonopod with a reduced lobe in posterior view ( Fig. 2B View Fig ), and the red coloration presented as a transverse red line on all metazonites, collum and telson ( Fig. 1B, D–F View Fig ) and a rounded process of the coxae of leg pair 3 of the male ( Fig. 1C View Fig ).
