Mangrove Long-jawed Spider
This species may be identified by its association with mangrove swamps, its dull colouration, details of the tooth arrangement of its chelicerae, and configuration of its sex organs. The male chelicerae are slender, divergent and longer than the length of the carapace. The abdominal colouration may vary; most have dark-coloured patterns, but some have lighter tones or are more palely coloured with yellow spots, as shown respectively in the two males on the upper row. The female has short chelicerae and shows distinct dark patterns on the dorsum.
