One of the largest and most distinctive sminthurids, typically in canopy communities, grazzing on algae on bark etc. Ant IV has 16 segments.

Dicyrtoma / Dicyrtomina

Common, distinctive and very pretty, the dicyrtomids are distinguished by ant IV being stubby and reduced. Note the waxy filaments in life, that vanish in IMS. The genera are separated by +/- a membrane around the claw of the foot.
