Myrmarachne plataleoides

Field Notes
Description:
Myrmaplata plataleoides, especially the females, mimic the Weaver Ants in size, shape and colour. The body of the M. plataleoides appears like an ant, which has three body segments and six legs, by having constrictions on the cephalothorax and abdomen. This creates the illusion of having a distinct head, thorax and gaster of the weaver ant, complete with a long and slender waist. The large compound eyes of the weaver ant are mimicked by two black patches on the head. The female's front legs resemble the feelers of the Weaver Ants, while the males resemble a larger ant carrying a smaller one.
The scientific name of the genus literally translates as "ant spider".
Ant-mimic jumping spider
Notes:
Kerengga ant-like jumpers are sexually dimorphic. Female jumpers, measuring about 6–7 mm, are the best mimics of the weaver ants while the males which usually measure about 9–12 mm in length give the appearance of a weaver ant carrying a minor worker due to their elongated chelicerae which may be as long as one-third to half their body length. These elongated chelicerae are a secondary sexual characteristic of the males. The males use their long fangs like swords to fight off rivals. They can split their jaws, normally held closed, to unfold their fangs when required.
