Tetragnatha hasselti is a species of long-jawed orb weaver spider in the family Tetragnathidae. It has a wide distribution across Asia, from India to China and Indonesia (Sulawesi).[1]

Taxonomy

The species was first described by Tamerlan Thorell in 1890 from a female specimen collected at Gorontalo in Sulawesi, Indonesia.[2] The species was named in honor of A. W. M. Van Hasselt, who provided the type specimen to Thorell.[2]

Two species have been synonymized with T. hasselti: Tetragnatha aduncata Wang, 1991 was synonymized by Song, Zhu & Chen (1999),[3] and Tetragnatha zhuzhenrongi Barrion et al., 2013 was more recently synonymized by Lin et al. (2023).[4]

Distribution

T. hasselti is widely distributed across Asia. It has been recorded from India, China, and Indonesia (Sulawesi).[1] The species appears to be particularly common in rice field habitats across its range.[5]

Habitat

Tetragnatha hasselti is commonly found in rice fields and other agricultural habitats.[5][6]

Description

The original description by Thorell noted that females reach about 12 millimeters in total body length, with the cephalothorax measuring approximately 3.5 mm long and 1.5 mm wide.[2] The species is characterized by its distinctive chelicerae, which are long and strongly curved outward at the base, with a complex arrangement of teeth along the cheliceral furrow.[2]

The cephalothorax is dark brown to blackish, while the abdomen appears grayish-silver due to dense minute silvery-white spots scattered across a dark grayish-black background.[2] The legs are yellowish to reddish-testaceous.[2]
