Type locality.

China,Yunnan, Puer.

Type materials, examined.

Female holotype, China: Yunnan, Puer, X/2008, Heng Xiao leg, (Ar.-MWHU-YNPE0801); paratypes: 5 males and 4 females (including 2 male immatures and 1 female immature) (Ar.-MWHU-YNPE0802-06, Ar.-MWHU-YNPE0807-10), same data as holotype.


Euscorpiops puerensis  differs from all other species in the genus on the basis of the following combination of characters: 18 external trichobothria (5 eb, 2 esb, 2 em, 4 est, 5 et), and 10 or 11 ventral trichobothria in the pedipalp patella (10 specimens); che la with a length/width ratio average of 2.7 in males and females (5 males and 2 females); pedipalp chela fingers of adult females and males scalloped; pectinal teeth count 7-8; pectinal fulcra present.

Euscorpiops puerensis  appears to be closely related to Euscorpiops vachoni  Qi, Zhu and Lourenço, 2005: both are medium-sized scorpions characterized by the presence of 10 or 11 trichobothria on the ventral surface of pedipalp patella, a pronounced lobe on the movable finger and a corresponding notch on fixed finger of adult males, 7-8 pectinal teeth. The shape of the chela manus provides the most pronounced difference between them, in Euscorpiops puerensis  is flat dorsoventrally, whereas it is short, stout, and robust in Euscorpiops vachoni  . Euscorpiops puerensis  may be distinguished from Euscorpiops kubani  and Euscorpiops sejnai  Kovařík 2000 by means of the following features: pedipalp chela fingers are distinctly scalloped on adult males and females in Euscorpiops puerensis  , whereas in Euscorpiops kubani  chela fingers are scalloped on male and nearly straight on female, and in Euscorpiops sejnai  male chela fingers are slightly scalloped (female unknown); 10-11 trichobothria on ventral surface of patella in Euscorpiops puerensis  , whereas there are 9 in Euscorpiops sejnai  , and 9-10 in Euscorpiops kubani  (11 rarely); chela with a length/width ratio average of 2.7 on males and females, whereas in Euscorpiops kubani  is higher than 2.7, and on Euscorpiops sejnai  is 2.75; 7-8 pectinal teeth, whereas there are 4-7 in Euscorpiops sejnai  , 6-8 in Euscorpiops kubani  ; total length 48.8 to 60.0 mm in Euscorpiops puerensis  , whereas both Euscorpiops sejnai  and Euscorpiops kubani  are smaller than 48.0 mm ( Kovařík 2000, 2004, 2005).
