Gonatium tridentatum
Gonatium tridentatum is a species of dwarf spider in the family Linyphiidae, described in 2025 by Muhammad Irfan, Chang-Cheng Zhang, Yu-Jun Cai, and Zhi-Sheng Zhang. It is endemic to Jiangjin District, Chongqing, China.
Diagnostic characteristics
Gonatium tridentatum can be easily recognized by a unique feature in males: a small leg-like structure near their reproductive organ has three distinct tooth-like points, unlike its close relative Gonatium japonicum, which has only one.Another distinctive trait in males is a long, curved spine shaped like the letter "C", which wraps close to another part of the body called the cymbium, ending slightly beyond it. The cymbium itself is shaped like a hoof with a small bump on the side.
Females of this species are identified by their reproductive structures, which include spiral-shaped internal ducts and round, globular organs where sperm is stored, unlike the more oval shapes found in similar species.
