  Singapore Tarantula
Phlogiellus inermis (Ausserer) 1871
 

Female
Nocturnal. Hides in silk-lined spaces among leaf litter.

When disturbed, the spider will adopt a threat posture by lifting its cephalothorax and spreading its jaws and first two pairs of legs.
Classification: Family Theraphosidae, Hairy Mygalomorph Spiders
Habitat: Leaf litter, especially near the base of tree trunks in waste-land and gardens.
Female: 20 mm.
Male: 17 mm.
Distribution: Singapore, Malaysia, Indonesia.
Theraphosidae and several other families of primitive spiders are collectively known as "Mygalomorph Spiders".
These are hairy, robust spiders with heavy jaws projecting forward horizontally from the cephalothorax. The fangs point backwards, instead of facing each other like a pair of pincers as in most spiders. On the underside of the abdomen are two pairs of book-lungs, whose positions are marked by four pale patches.

Most Theraphosids live on the ground, but some can be found in holes high in trees. Some Theraphosids are kept as pets in the United States, where they are known as "Tarantulas" or "Bird-Eating Spiders".
