Types. Holotype, male, 12 mm. Paratypes, 2 males, 1 female, ZMUC .

Type locality. Patio of Hotel Central , Porlamar, Margarita Island, Venezuela, under stones in the patio about 60 m from the sandy sea shore .

Ecological type. Beach-hoppers.

Habitat. Living at the back of sandy beaches.

Diagnosis (male). Based on Stephensen (1948).

Gnathopod 2 propodus palm without proximal sinus, with large distal sinus; with proximal spine defining palm. Pereopod 7 not incrassate. Telson with 7–8 robust setae per lobe.

Remarks. Platorchestia margaritae differs from the other species in the genus in having a large spine defining the proximal margin of the palm of male gnathopod 2.

Venables (1981 a –c) describes aspects of the physiology and ecology of the species. Martin & Diaz (2003) reported it as common on sandy beaches in Anzoátegui, Nueva Esparta and Sucre, Venezuela.

Distribution. Venezuela. Margarita Island ( Stephensen 1948): Cumaná ( Venables 1981 a –c).
