BRAZIL (NMW) • 1 undetermined sex; Minas Gerais; 16 Mar. 1923. • São Paulo, Pindamonhangaba.Diagnosis.Body not very robust, head oval, pronotum longer than wide and subconical, and prominent tubercles over the body as in E. fraterculus, E. longiceps, E. soesilae, E. tuberculosus, and E. volans. Different from E. fraterculus by antennomeres 6–10 as long as wide (transverse in E. fraterculus) and by each elytron with four rows of tubercles (3 in E. fraterculus), from E. longiceps by larger eyes, from E. tuberculosus by antennae of same length as head (almost 2 × longer than head in E. tuberculosus) and from E. soesilae and E. volans by pronotum with four rows of tubercles (5 rows in other two species).Additional characters.Antennae (Fig. 9 E) with scape as long as antennomeres 2–5; antennomeres 2 and 3 subequal in length; antennomeres 2–5 longer than wide, 6–10 subquadrate, antennomere 11 slightly smaller than 10; labrum (Fig. 10 E) with three denticles of subequal size; abdomen with tergites III – V and paratergites of segment III bearing small tubercles, VI bearing only impressions at base; sternites III – VI with ridges extending beyond posterior margin and few lateral tubercles. Aedeagus (Fig. 13 J, K) with median lobe short and stout, with truncate dorsal strut near foramen, slightly narrowing towards apex, apex of median lobe rounded.Measurements.TL: 6.5–7.0; HL: 1.53; HW: 0.8; PL: 1.28; PW: 0.92; EL: 1.39; EW: 1.47; LA: 0.9.Distribution.BRAZIL, Goiás, Espírito Santo, Rio de Janeiro, São Paulo, and Santa Catarina (Fig. 15).Host ant.Labidus praedator.Remarks.Some of the studied specimens are old, entirely glued to cardboards, and therefore fragile. In order to preserve these specimens, it was decided not to unglue them, which made sex determination impossible. Wasmann (1900) did not designate a holotype or define the type locality of the species; he only described two specimens that were found in two localities, Teresópolis (Brazil, Rio de Janeiro) and Joinville (Brazil, Santa Catarina), and we did not have access to the other specimen from the type series deposited in Wasmann’s collection to confirm the conspecificity of the syntypes. The syntype deposited in Borgmeier’s collection (MZSP) originally belonged to Wasmann’s collection, as indicated by the label “ Ex. Coll. Wasmann ”, and is the same specimen Borgmeier (1949) mentioned as the “ paratype ” in his review, originating from Joinville (Brazil, Santa Catarina). The exact locality of the other specimen in the type series is unknown. Since Wasmann did not designate a holotype or a type locality, and given our inability to access the other syntype, we here designate the aforementioned specimen as a lectotype, thereby fixing the type locality for Joinville, Santa Catarina Brazil.
