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][2][3][4][5][6]
Description
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.[2][3][4] The cephalothorax varies from blackish-brown to yellowish-brown with a distinct median dorsal stripe running the length of the carapace.[1][3][4] White setae are typically present on the pedicel.[1][2] The sternum is blackish-brown.[1][4] The abdomen varies from blackish-brown to yellowish-brown, with a subdued brownish-yellow longitudinal dorsal stripe.[1][4] 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][2][4][5] The ventral side of the abdomen is yellowish-brown with a blackish-brown middle.[1][2][4][5]
Identification
Descriptive diagnostic features with illustrations can be found in Koch 1878,[1] Saitō 1939,[7] and Namkung 2003.[4] Diagnostic photographs are provided in Baba and Tanikawa 2015[3]
Visual Identification
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.[2][3] 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][3]
Habitat
Pardosa astrigera have been found on plains, mountains, paddy fields, open grasslands, riverbanks, and other areas. They are often found in relatively dry regions.[2][3][4]
Seasonality
Adult males and females can be found from spring to autumn.[3]
