Type material. CHINA, Hunan Province: Holotype male from Zhangjiajie City, Sangzhi County, Tianpingshan Forest Farm , Davidia involucrata Garden , 29.78°N, 110.09°E, 1401 m, 20 June 2017, Y. Zhong & Y. Zhu leg. ( CBEE, LJ05088 ) . Paratypes: 3 males, 10 females, with same data as for holotype ( CBEE, LJ02371 – LJ02378 , LJ05065 – LJ05066 , LJ05072 – LJ05073 , LJ05080 ) ; 3 males, 3 females, Zhangjiajie City, Zhangjiajie National Forest Park, Huangshizhai , 29.34°N, 110.46°E, 454 m, 8 June 2018, F. Liu, J. Zhang, J. Lu, R. Zhong & Z. Li leg. ( CBEE, LJ02392 – LJ02397 ) .

Etymology. The specific name is derived from the

Latin adjective explanatus, -a, - um, meaning “flattened”, referring to the shape of RTA; adjective.

Diagnosis. The male of P. explanata Zhang, Jäger & Liu , spec. nov. resembles those of P. dhulensis Jäger, 2001 , P. hyatti Jäger, 2001 and P. martinae Jäger, 2001 (Jäger 2001) by sickle-shaped E and sub-apical EP. It can be recognised by huge EP (thinner and shorter in the other species). Females of P. explanata Zhang, Jäger & Liu , spec. nov. is similar to those of P. exiguoides ( Song & Zhu, 1999) ( Song et al. 1999) by the posterior margins of LL with median indentation. It can be recognised by anterior margins of LL smoother (distinctly curved in P. exiguoides ).

Spermophor visible submarginally on retrolateral T in ventral view. RTA arising medially to distally from Ti, with flat basal part. vRTA longer than dRTA, the former with thinner tip, the latter with rounded apex.

Colouration ( Figs 105A–B ): DS reddish brown with dark spots, two lateral bands, margin with thin dash line and brown patterns. Fovea and striae distinctly marked. OS dorsally with distinct pattern, lateral with irregularly spotted. OS ventrally with few spots and with triangleshaped patch in front of spinnerets.

FEMALE (LJ02371): Measurements: Medium sized. Body length 10.6–11.2, DS length 5.0, width 4.2, OS length 5.8, width 3.7.
