Type material: Holotype: ♂ from Parque Estadual de Itaúnas (18º25’S, 39º42’W), Conceição da Barra, Espírito Santo, Brazil, 15 December 2002 – 6 March 2003, Equipe Biota leg. (IBSP 60005).GoogleMaps 

Etymology. The specific name honours Klaus Meine, German singer, songwriter, lead singer of the hard rock band Scorpions; name in genitive case.

Diagnosis. Males of E. klaumeinei sp. nov. resemble those of E. andrematosi  sp. nov. by the triangular shape of the TBC in the male palps ( Figs 43View FIGURES 40–44, 46View FIGURES 45–49). They are distinguished by the RTA distally flattened and almost straight in retrolateral view ( Figs 44View FIGURES 40–44, 49View FIGURES 45–49) (bent at a 90º angle in E. andrematosi  sp. nov.) and by the MA with a widened base (same width throughout in E. andrematosi  sp. nov.) ( Figs 43View FIGURES 40–44, 48–49View FIGURES 45–49). Females are unknown.

Description. Male (Holotype): Prosoma brown, darker at lateral margins; fovea slightly darker; eye borders black. Chelicerae brown. Endites pale brown, distally cream colored. Labium brown, with dark brown base. Sternum orange with pale brown margins. Legs and pedipalps brown, slightly lighter than prosoma. Opisthosoma cream colored; dorsally with brown pattern of spots on anterior half and chevron-like marks medially down posterior half; ventrally with few scattered brown spots. Spinnerets pale orange ( Figs 40–41View FIGURES 40–44). Total length 10.3. Prosoma: 4.6 long, 3.9 wide. Opisthosoma: 5.5 long, 3.2 wide. Eye diameters: 0.34, 0.25, 0.20, 0.27; interdistances: 0.25, 0.12, 0.40, 0.35, 0.17, 0.08. Legs (4123): I: 13.4 (3.9, 2.3, 3.4, 3.0, 0.8); II: 13.3 (4.1, 2.4, 3.1, 2.9, 0.8); III: 10.8 (3.4, 1.7, 2.5, 2.5, 0.7); IV: 14.2 (4.4, 1.6, 3.2, 3.9, 1.1). Spination follows the generic pattern except femur III r1-0-0; tibiae I–II: v4-2 -2; tibia IV v2-2 -2; metatarsus I–II v2-1 r-0. Palp: VTA conical, retrolaterally displaced; RTA single, slightly over 3 times longer than wide, retrolatero-distad in ventral view; TBC slightly wider than long; MA 1.5 times longer than basal width, arising from tegulum at 5:30 o’clock position; E arising from tegulum at 7 o’clock position ( Figs 42–49View FIGURES 40–44View FIGURES 45–49).

Female unknown.

Distribution. Only known from the type locality in Espírito Santo ( Fig. 65View FIGURE 65).
