(Sal- 019, ASM-JGSU) ; 1 ♀, 26°38'13.2"N, 114°6'39.6"E, 1099 m a. s. l., other data as same as previous (Sal- 019, ASM-JGSU) .

Diagnosis.

The female of this species can be easily distinguished from that of all other species by the nearly double C-shaped copulatory ducts (vs circular, one C-shaped, or other shapes in other species) and the C-shaped spermathecae (vs oval or spherical in other species) ( Logunov and Marusik 2014; Peng 2020; Wang and Li 2022; Wang et al. 2023 a) (Fig. 5 C, D ).

Description.

Habitus as in Fig. 5 A, B . Total length 2.21, carapace yellow to brown, with large patches of black pigment around PME and PLE eye cups, 0.95 long, 0.77 wide, cup-shaped, with many short white setae in dorsal view. Eye sizes and interdistance (Fig. 5 A ): AME 0.24, ALE 0.14, PME 0.05, PLE 0.11, AME - AME 0.03, AME - ALE 0.01, PME - PME 0.58, PME - PLE 0.15, AME - PME 0.31, AME - PLE 0.48, ALE - ALE 0.52, PLE - PLE 0.59, ALE - PLE 0.32. MOA 0.61 long, front width 0.41, back width 0.73. Chelicerae (Fig. 5 B ) pale yellow, mottled, with two promarginal and four retromarginal teeth. Endites pale yellow, mottled, as long as wide. Labium yellow-brown, wider than long. Sternum (Fig. 5 B ) pale yellow-brown, mottled, broadly oval, slightly longer than wide, lateral margin slightly thickened, posterior end blunt. Abdomen (Fig. 5 A, B ) yellowish, dorsally with five pairs of dark brown stripes, anterior two touching, posterior three touching, 1.08 long, 0.91 wide, completely covered sparse elongated setae, anterior part with many discrete macrosetae; venter pale yellow. Legs missing.

Epigyne (Fig. 5 C, D ). Atrium very large, oval, nearly covering all areas of epigyne; copulatory openings small, antero-medially located, separated by half width of atrium; copulatory ducts long, double C-shaped; spermathecae C-shaped, posterior part human stomach-shaped; fertilization ducts subpostero-medially located, slightly separated at base, directed anteriorly.

Distribution.

Known only from Jiangxi Province, China (Fig. 13 ).

Remarks.

Ying et al. (2021) first recognized the species as new and had labeled the male as a holotype, but did not recognize the other salticid specimens collected from nearby localities. This is probably because the (preserved) female is pale and presumably had faded in alcohol. After re-examination, these two female specimens were considered as allotypes of male E. pengi .
