Porcellio lamellatus

About Porcellio lamellatus

Porcellio lamellatus is an isopod crustacean in the family Porcellionidae. Published sources characterize its origin status as adventive. Published Kauaʻi evidence documents the species from Kauaʻi. The cited evidence includes records dated or referenced to 1996. Evidence types include distribution table. These records establish a documented Kauaʻi occurrence but are not automatically interpreted as a present-day abundance estimate. The documented Kauaʻi habitat context includes terrestrial. For current-status context, historical Kauaʻi occurrence; current population status not reassessed. The source reports the Kauaʻi material as Porcellio lamellatus lamellatus, including a Haʻena record from 1973; the public record is retained at species level with the subspecies form as an alias. The available Kauaʻi evidence does not support adding island-specific claims about diet, reproduction, behavior, population size, or trend unless those points are stated in the cited sources, so they are not inferred here. Keeping the accepted taxonomic concept together with the dated occurrence evidence allows later surveys to distinguish historical documentation from contemporary status.
