Two-horned Debris Spider
The female may be recognised by its globose abdomen with a pair of conical protuberances on the dorsum. The protuberances may be partially or entirely black. While sub-adult males may have the variegated colouration as in the females, the abdomen becomes predominantly dark brown upon maturity.
| Length | 3–5 mm; 3 mm. |
| Habitat | Open areas, often associated with an aquatic environment such as beaches, lakes, reservoirs, and mangroves. |
| Biology | The web of mature females measures 5–6 cm in diameter. Egg sacs are placed in a single row like a string of beads. along a radial line which passes through a free sector at the upper part of the web. As many as seven egg sacs may be found in a string. The spider sits at the hub with legs retracted, simulating the last bead of the chain. Webs without egg sacs do not have a free sector. In this case, the spider places pellets of debris along a vertical line above and below the hub on which it sits, thereby presenting itself as another pellet in the same chain. |
| Type Locality | Mawlamyine, Myanmar. |
| Distribution | Widespread, including Singapore, Malaysia (Johor), Thailand, Myanmar, Vietnam, Philippines, China, India, Japan. |
