Beaded Egg Sac Matchstick Spider
With a colour varying from whitish to yellowish green, this species can be identified with certainty only through microscopic examination of its sexual organs. Nevertheless, the egg sac offers a clue to distinguish it from N. phyllicola. the other Nipisa species found in Singapore. In this species, the egg sac is like a string of beads, comprising 9-12 eggs arranged in a single row.
