Diagnosis.

The female of this species resembles that of P. subaureolus Bösenberg & Strand, 1906 (see Yin et al. 2012: 1250, fig. 672 b, c) in having widely separated oval spermathecae, but it can be easily separated from it by the broad median septum (vs narrow) and the broad copulatory ducts (vs narrow) (Fig. 1 C, D ). For the male diagnosis, see Long et al. (2022).

Abdomen 1.71 long, 1.12 wide.

Coloration (Fig. 1 A, B ). Carapace white to red-brown, laterally with broad red-brown stripes. Medially with a white V-shaped mark. Chelicerae and endites yellow to brown. Labium brown. Sternum white to brown, laterally with brown spots. Legs white to dark brown, with many dark brown stripes or annulations. Abdomen white to dark brown, with many white spots and yellow muscle sigilla; venter white to yellowish.

Epigyne (Figs 1 C, D , 8 A ). Copulatory openings located at antero-lateral part of epigyne. Median septum broad, sub-posterior part slightly constricted. Copulatory ducts broad, anteriorly curved, posteriorly slightly separated. Glandular appendages slightly protruding, very small, directed laterally. Spermathecae oval, widely separated. Glandular mounds mastoid-like, located on anterolateral part of spermathecae, directed anterolaterally. Fertilization ducts long, more than 2 / 3 length of spermathecae, directed anterolaterally.

Male. See Long et al. (2022) for description; habitus is shown in Fig. 2 A, B and the palp is shown in Fig. 2 C – E .

Remarks.

This species is numerous in subtropical broad-leaved forests. The specimens were collected on shrubs and broad-leaved trees by sieving.

Distribution.

Known from Guizhou ( Long et al. 2022), Hunan (Fig. 10 ), and Jiangxi (Fig. 10 ), China. It may be broadly distributed in southern China.
