Pardosa sumatrana

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]
