Etymology: Pomacentrus: Greek, poma, -atos = cover, operculum + Greek, kentron = sting (Ref. 45335); rodriguesensis: This species is named Pomacentrus rodriguesensis with reference to the type locality. It is probably restricted to this location as collections from other Mascarene Islands have failed to yield specimens.

Pomacentrus rodriguesensis is currently known only from Rodrigues. It is relatively common in the lagoon at depths between 9-18 m on reefs that contain mainly Acropora corals that are affected by silt deposition. Their territorial behaviour suggests that, although they may not dramatically modify the benthic reef environment, they may promote the biomass of their preferred food algae. Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
Pomacentrus rodriguesensis 现在被已知只来自 Rodrigues 。 它是相当普遍的在舄湖中在深度介于 9- 之间， 18 公尺在主要地包含 Acropora 珊瑚的礁上那是被淤泥沈淀影响。
