INDEX to Spiders of Sungai Tawau
 



Family Gnaphosidae
(Flat-bellied Ground Spiders)


Family :  Gnaphosidae
Genus :  Micaria

Generally, ground spiders are characterized by having barrel-shaped anterior spinnerets that are one spinneret diameter apart.

The main exception to this rule is found in the ant-mimicking genus Micaria. Another characteristic is an indentation in the endites (paired mouthparts anterior and lateral to the labium, or lip).

All ground spiders lack a prey-capture web and generally run prey down on the surface. They hunt at night and spend the day in a silken retreat.

The thick-walled egg sacs are guarded by the mother until the spider lings hatch.

Only 5 species of Ground Spider is recorded in Borneo Island, despite this is the second largest family.
