Type material.
Holotype: ♂ (SYNU-Ar00357), China, Liaoning, Dandong, Fengcheng, Dalishu Village, Yaowanggu (40°26.30'N, 123°56.65'E, 298 m), 2 July 2023, Q. He & Z. Yao leg. Paratypes: 2♂ (SYNU-Ar00358-59), 3♀ (SYNU-Ar00360-62), same data as for the holotype.
Etymology.
The specific name is dedicated to the late Deputy of China’s National People’s Congress, Fengmei Mao (1949-2014). Under the leadership of Fengmei Mao, the villagers of Dalishu in Liaoning Province were inspired to work hard and work smart, embarked on an entrepreneurial journey from 1980, and transformed their spartan hamlet into the prosperous and flourishing community it is today.
Diagnosis.
The new species resembles P. phoenixus (Fig. 4D-F View Figure 4 ; Yao and Li 2012: figs 144A-D, 145A-C) by having similar epigyne (Fig. 3A View Figure 3 ) and male chelicerae (Fig. 3D View Figure 3 ), but it can be easily distinguished by procursus lacking ventro-subdistal apophysis (Fig. 2C View Figure 2 ; vs present, arrow 2 in Fig. 4D View Figure 4 ), by prolatero-subdistal sclerite of procursus lacking angular proximal apophysis (Fig. 2C View Figure 2 ; vs present, arrow 3 in Fig. 4D View Figure 4 ), by uncus nearly half-round, with latero-median protrusion (arrow in Fig. 3C View Figure 3 ; vs with latero-median and distal protrusions, Fig. 4E View Figure 4 ), by anterior arch medially strongly curved (bow-shaped, Fig. 3B View Figure 3 ; vs straight, Fig. 4F View Figure 4 ), and by pore plates nearly half-round (Fig. 3B View Figure 3 ; vs nearly triangular, Fig. 4F View Figure 4 ).
Description.
Male (holotype): Habitus as in Fig. 3E, F View Figure 3 . Total length 4.85 (5.08 with clypeus), carapace 1.41 long, 1.62 wide, opisthosoma 3.44 long, 1.34 wide. Legs: I: 36.90 (9.55, 0.74, 9.04, 15.19, 2.38), II: 25.06 (6.99, 0.64, 6.22, 9.68, 1.53), III: 17.98 (5.19, 0.60, 4.17, 6.79, 1.23), IV: 23.47 (6.79, 0.68, 5.77, 8.85, 1.38); tibia I L/d: 65. Eye interdistances and sizes: PME-PME 0.26, PME 0.15, PME-ALE 0.04, AME-AME 0.06, AME 0.10. Sternum width/length: 1.10/0.97. Carapace yellowish, with brown radiating marks and marginal brown bands; ocular area yellowish, with median and lateral brown bands; clypeus yellowish, with brown median marks; sternum yellowish, with brown marks and posterior median stripe. Legs yellowish, but dark brown on patellae and whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and proximal and subdistal parts of tibiae. Opisthosoma yellowish, with dorsal and lateral spots. Chelicerae (Fig. 3D View Figure 3 ) with pair of proximo-lateral apophyses, pair of distal apophyses with 2 teeth each, and pair of frontal apophyses. Legs with short erected setae on tibiae, metatarsi, and tarsi; retrolateral trichobothrium on tibia I at 3% proximally; tarsus I with 33 distinct pseudosegments.
Palp as in Fig. 2A, B View Figure 2 ; trochanter with long (4 times longer than wide), retrolaterally strongly bulged ventral apophysis (arrow 1 in Fig. 2B View Figure 2 ); femur with small retrolatero-proximal protrusion (arrow 2 in Fig. 2B View Figure 2 ) and indistinct ventral protrusion; tibia with prolatero-ventral protrusion (arrow in Fig. 2A View Figure 2 ); procursus simple proximally and complex distally, with proximally wide prolatero-subdistal sclerite (arrow 1 in Fig. 2C View Figure 2 ) equipped with curved proximal apophysis (arrow 2 in Fig. 2C View Figure 2 ), curved distal apophysis (arrow 3 in Fig. 2C View Figure 2 ), and 3 dorsal spines (arrow in Fig. 2D View Figure 2 ); uncus nearly half-round, 1.3 times longer than wide, with scales and latero-median protrusion (arrow in Fig. 3C View Figure 3 ); bulb without appendix; embolus weakly sclerotized, with some indistinct transparent distal projections (Fig. 3C View Figure 3 ).
Female (paratype, SYNU-Ar00360): Similar to male, habitus as in Fig. 3G, H View Figure 3 . Total length 5.83 (5.99 with clypeus), carapace 1.45 long, 1.68 wide, opisthosoma 4.38 long, 2.33 wide; tibia I: 8.85; tibia I L/d: 52. Eye interdistances and sizes: PME-PME 0.22, PME 0.15, PME-ALE 0.05, AME-AME 0.06, AME 0.09. Sternum width/length: 1.11/0.95. Clypeus brown.
Epigyne (Fig. 3A View Figure 3 ) 1.2 times wider than long, with antero-median brownish marks, short oval knob (1.6 times longer than wide), and pair of lateral protrusions anterior to epigynal plate (arrow in Fig. 3A View Figure 3 ). Vulva (Fig. 3B View Figure 3 ) with strongly curved, sclerotized anterior arch, pair of nearly half-round pore plates (2 times longer than wide), and pair of curved lateral sclerites (arrow in Fig. 3B View Figure 3 ).
Variation.
Tibia I in two paratype males (SYNU-Ar00358-59): 10.51, 10.90. Tibia I in the other two paratype females (SYNU-Ar00361-62): 7.76, 8.01.
Natural history.
Specimens were found on the underside of overhang on rocky outcrop and wooden railings in rural areas.
