Goneplacidae

Ommatocarcinus macgillivrayi, from Macgillivray 1852.

Belongs within: Heterotremata.

The Goneplacidae has long been recognised as a somewhat poorly defined grouping of crabs of small to medium size.

Characters (from Davie 2002): Carapace hexagonal, transversely rectangular, trapezoidal, or transversely ovate; dorsal surface more or less convex, typically smooth, regions poorly defined; frontal margin usually entire, sometimes bi- to multilobate; anterolateral margins usually armed with 1-4 teeth or lobes, but sometimes entire. Orbits complete, may be moderately or greatly elongate. Interantennular septum typically narrow. Antenna folding obliquely or transversely. Third maxillipeds with carpus articulating at or near antero-internal angle of merus. Ambulatory legs gressorial, not broadly flattened for swimming. Male abdomen with seven free segments or with segments 3–5 fused and immovable. Male first gonopod moderately stout, weakly curved or sinuous; second gonopod short or long, but usually shorter than first. Male genital openings sternal or sterno-coxal, with vas deferens passing along open or closed groove in sternum.
