Leucauge argentina is a species of long-jawed orb weaver in the family Tetragnathidae. It was first described by van Hasselt in 1882 as Theridion argentinum from Sumatra, Indonesia. [1]
L. argentina is found across Southeast Asia, including Thailand, Singapore, Indonesia (Sumatra), the Philippines, and Taiwan. [1] [2] The species was first recorded from Taiwan by Tso and Tanikawa in 2000. [2]
Based on specimens from Taiwan, females are larger than males. [2] Females have a total body length of approximately 4.34 mm, while males measure about 2.60 mm. The carapace is yellowish with a darker head region, and the legs are brown without distinct banding patterns. The abdomen displays silver speckles and black markings. [2]
The carapace length to width ratio is about 1.30 in females and 1.25 in males. Female specimens have a distinctive epigynum structure, while males possess characteristic palpal features used for identification. [2]
L. argentina constructs orb webs and is associated with agricultural areas, particularly rice fields in Southeast Asia. [3]
