'''''Grypotyphlops acutus''''', also known as the '''beaked worm snake''', '''beaked blind snake''', or '''beak-nosed worm snake''', is a harmless [[Typhlopidae|blind snake]] [[species]] [[Endemism|endemic]] to peninsular [[India]]. It is the only species in the genus '''''Grypotyphlops'''''. No [[subspecies]] are currently recognized.<ref name=RDB/><br />
<br />
== Taxonomy ==<br />
''Grypotyphlops'' is thought to group with the [[Africa]]n [[Typhlopidae|typhlopids]] in the genera ''[[Afrotyphlops]]'', ''[[Letheobia]]'', and ''[[Rhinotyphlops]]'', being the [[sister group]] to the latter two and having dispersed from Africa to the [[Indian subcontinent]] during the [[Paleogene]]. This contrasts with the other blind snakes in the Indian subcontinent, which are thought to have either mainland Asian ancestry (''[[Indotyphlops]]'' and ''[[Argyrophis]]'') or be descended from ancient [[Gondwana]]n endemics of [[Insular India]] (''[[Gerrhopilus]]'').<ref>{{Cite journal |last1=Sidharthan |first1=Chinta |last2=Karanth |first2=K.

<br />
==Geographic range==<br />
This species is found throughout peninsular India south of the [[Ganges]] and [[Rajputana]] basins. The [[Type locality (biology)|type locality]] given is "''inconnue''" ([[French language|French]] for unknown).<ref name="McD99"/><br />
