Macrogomphus quadratus is large and commonly widespread in Sabah’s shallow streams in dense alluvial forest.

The female Macrogomphus quadratus body total length is 76mm,
Front wings span = 110mm,
Hind wings span = 102 mm
Abdomen length = 56mm

Macrogomphus quadratus synthorax is robust though the abdomen rather thin.

This female’s Macrogomphus quadratus synthorax is as robust as a male’s

The eyes are well separated, a feature which distinguishes them from all other Anisoptera species.
 

The ovipositor of this female Macrogomphus quadratus is very different from other familiar dragonflies. Segment 2 is extraordinary long.

The females lay their eggs alone, with a few quick passes over the weedy mud banks in shallow water.

10 meters from where I found this female is a small river with mud banks eroded by recent monsoon flood.
