Pardosa sumatrana is a species of wolf spider in the family Lycosidae. It was first described by Tamerlan Thorell in 1890 from specimens collected in Sumatra. [1]
The species was originally described as Lycosa sumatrana by Thorell in 1890. [2] It was transferred to the genus Pardosa by Hogg in 1919. [3]
Several species have been synonymized with P. sumatrana over the years. Chen & Gao (1990) synonymized Arctosa chengta and Pardosa davidi with P. sumatrana. [4] Barrion & Litsinger (1995) synonymized Chorilycosa arorai. [5] More recently, Abhijith et al. (2021) synonymized Pardosa mysorensis, [6] and Wang et al. (2021) synonymized both Pardosa tieshinglii and P. villarealae. [7]
P. sumatrana has a wide distribution across South and Southeast Asia. [1] It has been recorded from India, Sri Lanka, Nepal, Bhutan, Bangladesh, Myanmar, Thailand, China, the Philippines, and Indonesia (specifically Sulawesi). [1]
The species is commonly found in agricultural habitats, particularly rice fields, where it serves as a predator of agricultural pests. [8] It has also been found in forest floor litter and various ground-dwelling habitats. [9]
According to Thorell's original description, P. sumatrana has a dark cephalothorax marked with three longitudinal pale bands covered in grayish-white pubescence. The central band is the widest and uniform, while the lateral bands are narrow and irregular. The sternum is black, often with a longitudinal testaceous line at the front. [2]
The legs are olive-testaceous with dark annulations. The dorsal abdomen is covered with dense grayish pubescence and shows a pale or yellowish thick chevron mark at the front, followed by a thin black V-shaped mark, and usually pale spots arranged in four or two longitudinal series behind it. [2]
In females, the vulva consists of two very shiny black tubercles with a narrow septum between them and a narrow procurved ridge behind them forming a pale ∩-shaped structure. [2] Adult males measure approximately 5.75 mm in length, while females reach 6.5–8 mm. [2]
