This species occurs in the lowlands of the State of Rio de Janeiro, southeastern Brazil, close to sea level.
Habitat and Ecology
It lives in coastal "restinga" scrub, forest edge, and primary and secondary forest. It is an explosive breeder, using both small and large temporary ponds. A population from Rio de Janeiro had reproductive activity recorded for the month of December (Abrunhosa et al., 2006). It is not found in open habitat outside forest.
It is abundant where it is found.
The major threats are probably related to habitat loss due to fire, tourism and human settlement.
It occurs in several protected areas, including Bosque da Barra, and Floresta Nacional Mario Xavier.
Red List Status
Least Concern (LC)
Listed as Least Concern since, although its Extent of Occurrence is probably less than 20,000 km2, it occurs in an area of extensive, suitable habitat which appears not to be under significant threat, it has a presumed large population, and it is unlikely to be declining to qualify for listing in a more threatened category.
Izecksohn and Albuquerque (2000) separated the populations of Stereocyclops incrassatus from Rio de Janeiro as a separate species, reviving the previous name Stereocyclops parkeri.
