Diagnosis.

Females resemble those of P. subaureolus in having the similarly bell-shaped MS which is not delimited to SEF, but can be recognised by: (1) A comma-shaped (vs elongate-oval, nearly funnel-shaped) (cf. Fig. 8 C, D, F View Figure 8 and Fig. 11 D View Figure 11 ); (2) anterior keel of MS relatively wider, ~ 1 / 5–1 / 4 epigyne width (vs distinctly narrower, ~ 1 / 10–1 / 8 epigyne width) (cf. Fig. 8 D View Figure 8 and Fig. 11 D View Figure 11 ); (3) CD heavily sclerotised, not looped, distinctly thick and short, almost as thick as R, length ~ 1 / 2 epigyne (vs weakly sclerotised, distinctly thinner and longer, with a long cCD forming two loops before entering R, their thickness no more than 1 / 2 the diameter of R, length longer than epigyne) (cf. Fig. 8 E, G View Figure 8 and Fig. 11 E View Figure 11 ); (4) R elongate-oval, anteriorly separated by ~ 0.5 × diameters, posteriorly separated by ~ 1.3 × diameters (vs nearly spherical, separated by ~ 1 diameter) (cf. Fig. 8 E, G View Figure 8 and Fig. 11 E View Figure 11 ). Males of P. guiyang are also similar to those of P. subaureolus by the similar, blade-shaped VTA, lamellar RTA with a bifurcated tip, spine-shaped IR, and the more or less S-shaped SDL, but can be distinguished from the latter by: (1) Em claw-shaped, distinctly shorter, originating at the 10 o’clock position, terminating at the ~ 1 o’clock position (vs filiform, distinctly longer, originating at 8 o’clock position, terminating at ~ 1 o’clock position) (cf. Fig. 9 A, C, D View Figure 9 and Fig. 10 D – F View Figure 10 ); (2) Con distinctly shorter, enveloping the second half of Em, the coverage ranges from the 11 o’clock to the 1 o’clock position (vs distinctly longer, almost enveloping the entire Em, the coverage ranges from the 9 o’clock to the 1 o’clock position) (cf. Fig. 9 A, C, D View Figure 9 and Fig. 10 D – F View Figure 10 ); (3) in retrolateral view, the middle section of RTA distinctly narrower than its base and tip (vs not distinctly narrowed, the entire RTA is almost uniform in width) (cf. Fig. 9 D View Figure 9 and Fig. 10 F View Figure 10 ); and (4) vRTA noticeably prominent, distinctly longer and sharper than dRTA (vs vRTA small, both branches of RTA are similar in size and shape) (cf. Fig. 9 D View Figure 9 and Fig. 10 F View Figure 10 ).

Abdomen elongate-oval, dorsum with a narrow, purplish median band starting from behind pedicel, reaching 1 / 2 of abdomen length; posteriorly with numerous purplish-black streaks interspersed with many pale brown spots, forming a reticulated pattern; ventral abdomen uniformly pale brownish.

Epigyne (Fig. 8 C – G View Figure 8 ). Epigynal field slightly longer than wide; anterior and lateral margins not delimited, posterior margin rebordered; the arrangement of the various parts of the vulva (CD and R) are distinctly visible through integument. A small, located at anterior part of epigynal plate, divided by anterior keel of MS, represented by two comma-shaped cavities; the two cavities separated by ~ 1 diameter. MS bell-shaped, broad; anteriorly narrowed abruptly, ~ 1 / 5 epigyne width, with distinct edges and distinctly delimited to A; posteriorly widen gradually, ~ 1 / 2 epigyne width, with indistinct lateral rMS alongside with rSEF. SEF anteriorly and posteriorly narrowed, medially widened, ~ 1 / 3 epigyne width, not delimited to MS.

Palp (Fig. 9 A – D View Figure 9 ). Tibia relatively long, ~ 2 / 3 of Cy length, with two apophyses arising distally from tibia. Both tibial apophyses are lamellar and almost equal in length, nearly as long as palpal tibia length, including: a weakly sclerotised VTA, blade-shaped in ventral view and finger-shaped in lateral views; and a more sclerotised RTA which with wide base, narrowed middle section, and more or less biforked tip; both branches of RTA nearly triangular, vRTA heavily sclerotised, surface and edges smooth, apex angle is approximately 30 °, dRTA hyaline, surface rough and with several scratch-like textures, distal edge jagged, apex angle is approximately 90 °. Cy distinctly longer than tibia, basoretrolaterally with an indistinct CP. Te oval, ~ 1.37 longer than wide, proximally slightly swollen, prolatero-apically slightly excavated to accommodate Em and Con. SD sinuate, originating at distal portion of Te, aligning clockwise along the tegular retrolateral margin, forming a S-shaped SDL in ventral view, finally terminating at the ~ 10 o’clock position, and entering EmB. Em claw-shaped, EmB thick, inserted prolatero-apically (approximately 10 o’clock relative to Te), gradually tapering toward apex; EmT sharp and retrolaterally pointed, terminating at ~ 1 o’clock position.

Distribution.

China (Fujian, Guizhou, Hunan, Jiangxi; distribution records in Guizhou as in Fig. 23 A View Figure 23 ).

Comments.

Long et al. (2022) described the holotype male of P. guiyang in Chinese in the original paper. Wang et al. (2024) later described the female of the species for the first time but did not provide a diagnosis and redescription for the male. Therefore, to date, the male of this species lacks an English description. Here we diagnose and describe the male in English for the first time. Newly available specimens indicate that the species is also distributed in Mayanghe National Nature Reserve in Guizhou Province (Fig. 23 A View Figure 23 ).
