Front of the abdomen of the female tapers strongly and overhangs most of the carapace. The abdomen is tubular, tapers to the front and protrudes to the rear over the spinnerets. There are silver white patches all over the abdomen. The legs are long and thin with dark brown annulations.

Femora IV with uniform rakes of long curved trichobothria. There is also a substantial brush of hairs all round or almost all along tibia IV.

The Spinneret of a female Opadometa fastigata

The spinneret located in abdomen which helps the spiders to produce the silk for web.
Many species of spider have different glands to produce silk for different jobs, such as housing and web construction, defense, capturing and detaining prey, or mobility. Thus, different specialized silks have evolved with material properties optimized for their intended use. For example, Argiope argentata has five different types of silk, each for a different purpose.

The last pair of legs are well armed with strong spines (the hair brushes orgaiters) on the tibial segment of legs

Opadometa fastigata species typically build a web with a central component of heavy zigzag silk but there is not a string of insect debris stretched across the web.
