Justification:
In the previous Red List assessment for Isomma hieroglyphicum, the species was assessed as Data Deficient. New records are now available from scattered localities in eastern Madagascar from the north to the south of the island. Therefore the species is unlikely to be declining fast enough to qualify for listing in a threatened or the Near Theatened category. Assessed as Least Concern.

Errata [top]

Errata reason: When the 2008 assessment of this species was published in 2009, the 2006 citation reference was left attached to the account by mistake and hence the previous version of this assessment showed it as being published in 2006 although the assessment was only done in 2008. That error is corrected here and therefore a 2016 citation reference is now used; the 2009 reference that should have been used in the citation is under the References.
