Holotype , 1♂ , Lushui , Pianma Zhen , Yunnan , alt. 2300m , 2010-VII-6 ~7, collected by Bi Wen-Xuan ; paratypes , 2♂♂ 3♀♀ , same data as holotype. Distribution. China ( Yunnan ). Diagnosis. This species is similar to T . ( G .) wuyishanicus ( Zhang & Liu, 2009 ) , but differs by: epiphallus of male genitalia with upper notch smaller than lower notch, female subgenital plate triangular, at base almost as wide as length of plate, tip acute; corresponding status of T . ( G .) wuyishanicus ( Zhang & Liu, 2009 ) : epiphallus of male genitalia H-shaped, female subgenital plate triangular or quadrate, tip blunt. Etymology. The specific epithet refers to the small size of the body.
