Medium-sized scorpions, total length 50.0-59.8 mm. It can be distinguished from other species of Euscorpiops  by having thicker chelas. It can be ditinguished from other Euscopiops species  from Yunnan by the following features: pedipalp patella with 9 to 10 (rarely 11 or 8) ventral trichobothria; chela strong, length/width ratio: 2.9-3.2 (mean 3.0 in 3 males, and 3.1 in 4 females); pectinal fulcra present (obsolete in some females); chela fingers obviously curved; pectinal teeth: 7-8; pectinal fulcra present and small. Euscorpiops validus  can be ditinguished from related Euscopiops  species by the following features: in Euscorpiops shidian  there are 11 (rarely 10 or 12) ventral trichobothria on pedipalp patella, chela length/width ratio higher than 3.2 in Euscorpiops shidian  , higher than 3.3 in Euscorpiops yangi  and higher than 3.4 in Euscorpiops xui  ; chela fingers clearly curved in Euscorpiops validus  , whereas in Euscorpiops shidian  they are nearly straight, in Euscorpiops kubani  female nearly straight and in Euscorpiops yangi  they are slightly undulated in both sexes without sexual dimorphism; chela manus flat in Euscorpiops validus  , whereas in Euscorpiops vachoni  rounded.
