Mangrove Long-jawed Ant Jumper
The male is readily recognisable by the exceptionally long chelicerae, distinguished from M. markaha by a shorter pedicel and abdomen. Smaller males with shorter chelicerae also exist in Singapore as a variant of this species. The female (not shown here) resembles M. melanocephala but has no abdominal markings.
| Length | ♀ 4–5 mm; ♂ 8 mm, including chelicerae |
| Distribution | Singapore, Indonesia (Java, East Nusa Tenggara). |
| Habitat | Among forest foliage in Southeast Asia, but both the normal form and the smaller variants seem to be seasonally common in Singapore mangroves. |
