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 43
,
46
). They are distinguished by the RTA distally flattened and almost straight in retrolateral view (
Figs 44
,
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 43
,
48–49
). 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 (

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 42–49
).
