Cylindroiulus truncorum (Silvestri, 1896) (Figs. 2B, 7F) Descriptive notes: Male, see Blower (1985: 162, fig. 51) and Korsós & Enghoff (1990: 347, figs. 1, 5-8, 21, 30, 31). Identification: According to the diagnosis made by Korsós & Enghoff (1990), males of C. truncorum are recognized by promerite of gonopods slightly longer than mesomerite, without a deep mesal incision; opisthomerite with laterad bent smooth brachit, without setae or protuberances; paracoxal process long, slender and pointed, almost reaching the end of solenomerite (Blower, 1985: fig. 51; Fig. 7F). Distribution: It is widespread in Europe and North Africa, probably by several events of introduction (Blower, 1985; Korsós & Enghoff, 1990). The species has been reported in Hawaii, North and South America (Shelley et al., 1998; Hoffman, 1999). Cylindroiulus truncorum occurs mainly in synanthropic habitats such as greenhouses, gardens, and parks (Korsós & Enghoff, 1990). In Brazil, the species has been recorded only in urban areas in São Paulo. All records of the species were obtained from the literature.

Paraspirobolus lucifugus (Gervais, 1837) (Figs. 2C, 7 C-D) Descriptive notes: See Attems (1900: figs. 13-16) and Brölemann (1902: 184, figs. 223-227). Identification: According to the descriptions made by Attems (1900) and Brölemann (1902), males of P. lucifugus can be recognized by the anterior and posterior gonopods. Coxae of the anterior gonopods separated by wide sternum slightly indented in midline (Attems, 1900: figs.13-14; Brölemann,1902:fig. 226; Fig.7C).Telopodites of the posterior gonopods apically fusiform and with a broad lobe (Attems,1900: fig. 16; Fig. 7D). An overview of its taxonomic status was made by Jeekel (2001). Distribution: Paraspirobolus lucifugus is widespread in the tropics and in greenhouses from Europe (Jeekel, 2001; Enghoff et al., 2004; Korsós,2004). In Brazil,the species has been recorded only in the coastal region from the Atlantic Forest and in urban areas. All records of the species were obtained from the literature.

Cylindroiulus britannicus (Verhoeff, 1891) (Figs. 1D, 7E) Descriptive notes: See Schubart (1942c: 250, fig. 1) and Blower (1985: 158, fig. 49). Identification: Members of Julida are easily recognized by stipites of gnathochilarium in contact in the midline in their basal part (symphyognathous condition). The species is recognized by three pairs of setae on the anal valves (Blower, 1985: fig. 49a); opisthomerite with finger-shaped projection (Blower, 1985: fig. 49b); promerite simple; mesomerite shorter than promerite (Fig. 7E). Distribution: The order Julida is distributed in the Holarctic region, marginally also in SE Asia and Central America (Enghoff et al., 2015). Cylindroiulus britannicus is widespread in Europe and predominantly distributed in the Northwest region (Blower, 1985). The species has been recorded in southern India, New Zealand, South Africa (Hoffman, 1999), Chile, and Argentina (Golovatch, 2014; Shelley et al., 2014). In Brazil, the species has been recorded only in urban areas in the states of São Paulo and Rio de Janeiro. All records of the species were obtained from the literature.

Genus Erythrocricus Schubart, 1962 Erythrocricus Schubart, 1962: 69, as subgenus of Rhinocricus Karsch, 1881 (type species: Rhinocricus (Erythrocricus) sanguineostriatus Schubart, 1962). Erythrocricus – Hoffman, 1980: 79 (new status). Rhinocricus (Erythrocricus) sanguineostriatus – Marek et al. 2003: 71. Diagnosis Species of Erythrocricus differ from other rhinocricid genera by the combination of the following characters: both males and females have a transverse red line on body rings (Figs 1B, D–F, 3C–D), males present a sternite of the anterior gonopods triangular in anterior view and a rounded coxite (Figs 2A, 5A), each posterior gonopod has the external branch folded over the solenomere (Figs 2C, 5C). Species included Erythrocricus sanguineostriatus (Schubart, 1962) Erythrocricus electrofasciatus (Schubart, 1957) comb. nov. Distribution Occurring in the Atlantic forest (state of São Paulo), Cerrado biome (state of Goiás), and in the Amazonian and Pantanal biomes (Mato Grosso) of Brazil. Key to species of Erythrocricus (based on males) 1.

Erythrocricus sanguineostriatus (Schubart, 1962) Figs 1–3 Rhinocricus (Erythrocricus) sanguineostriatus Schubart, 1962: 70, figs 1, 2, 4. Rhinocrinus (Erythocricus) sanguineostriatus — Marek et al. 2003: 72. Erythrocricus miniatostriatus Schubart, 1962: 71, figs 3, 5. Syn. nov. 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. Diagnosis Erythrocricus sanguineostriatus (Schubart, 1962) resembles E. electrofasciatus (Schubart, 1957) comb. nov. by the shape of the anterior gonopod (Figs 2A, 5A) 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), and the red coloration presented as a transverse red line on all metazonites, collum and telson (Fig. 1B, D–F) and a rounded process of the coxae of leg pair 3 of the male (Fig. 1C).
