Pardosa astrigera is a species of wolf spider in the family Lycosidae. [1] They are found throughout Japan, Korea, China, Taiwan, and far east Russia. [1] [8] [9] [10] [11]
Pardosa astrigera is a small wolf spider with the body length ranging between 6–10 mm (0.24–0.39 in) for females and 5–9 mm (0.20–0.35 in) for males. [8] [9] [10] The cephalothorax varies from blackish-brown to yellowish-brown with a distinct median dorsal stripe running the length of the carapace. [1] [9] [10] White setae are typically present on the pedicel. [1] [8] The sternum is blackish-brown. [1] [10] The abdomen varies from blackish-brown to yellowish-brown, with a subdued brownish-yellow longitudinal dorsal stripe. [1] [10] There is a high degree of variation in the dorsal pattern on the abdomen, however the typical presentation includes several thin lateral chevrons and 5 pairs of spots along the margins. [1] [8] [10] [11] The ventral side of the abdomen is yellowish-brown with a blackish-brown middle. [1] [8] [10] [11]
Descriptive diagnostic features with illustrations can be found in Koch 1878, [1] Saitō 1939, [4] and Namkung 2003. [10] Diagnostic photographs are provided in Baba and Tanikawa 2015. [9]
Pardosa astrigera is one of the few spiders that can be identified at a glance, as these spiders have a unique longitudinal band on the median of the carapace. [8] [9] The band is yellowish-brown in color, rounded behind the eyes, forming a star shape around the fovea, and narrowing as it reaches the abdomen. [1] [9]
Pardosa astrigera have been found on plains, mountains, paddy fields, open grasslands, riverbanks, and other areas. They are often found in relatively dry regions. [8] [9] [10]
Adult males and females can be found from spring to autumn. [9]
