Assessment Information [top]

Red List Category & Criteria: Extinct ver 3.1
Year Published: 2013
Date Assessed: 2011-11-30
Assessor(s): De Grave, S. & Wowor, D.
Reviewer(s): Cumberlidge, N. & Smith, K.
Justification:
The species is only known from the type specimen collected from an unknown location in the Bogor Regency (2,664 km2) in Java, Indonesia in 1888. Surveys in the past 30 years in the area have failed to collect the species. This complex of freshwater shrimp species have been well surveyed in the wider region and based on the total lack of records over the past 30 years (surveyed every year) in the Bogor Regency and the level of development of the Regency since the description, the species is assessed as Extinct. It is however noted that Ou and Yeo (1995) consider that Macrobrachium leptodactylus could be a synonym of M. pilimanus, a widespread species in Java.
