Etymology: Named in honor of Dr. Dante Vailati, an Italian entomologist and biospeleologist, who contributed greatly to the studies of the entomofauna and arachnofauna of Greece.

Geographic range: GREECE. Western Greece (Aitoloakarnania); Central Greece (Fokida) ( Fig. 47).

Diagnosis. A medium-small Euscorpius species , total length 25–34.5 mm (mean 29.3 mm). Color of adults light brown to brown-reddish; darker reticulation or marbling on chelicerae, carapace, mesosoma, metasoma and legs may be present. The number of trichobothria on the pedipalp manus ventral surface is 4 (V 1-3 +Et 1). The number of trichobothria on the pedipalp patella ventral surface is 9–11. The number of trichobothria on pedipalp patella external surface is: eb = 4, eba = 4, esb = 2, em = 4, est = 4, et = 6–8 (7). The pectinal teeth number in males usually is 9–10; in females usually is 7–8, more rarely 9. Mean Lchel/Wchel ratio is 2.46 in males and 2.60 in females. Notch on the fixed finger very pronounced. Dorsal patellar spur well developed. Femur more or less as long as the patella; it may be slightly longer (usually in males Lfem/Lpat 1.013) or shorter (usually in females Lfem/Lpat 0.985). Carapace more or less as long as wide; it may be either slightly longer or wider, but tends to be wider (mean ratio Lcar/Wcar 0.986); mean distance from center of median eyes to anterior margin of the carapace is 41% of the carapace length. Mean ratio of Lmet/Lcar is 2.57 in males and 2.38 in females. Metasomal segment I in males usually longer than wide (1.051). Ventral row of spinules on tarsus usually ending with two larger, paired spinules.
