It is the only member of the genus Lochmias. The species is also known as the streamside streamcreeper.[2] DescriptionThis bird is about 6 in (15 cm) long, with a short tail and a long, thin, slightly curved bill. The plumage is dark brown, densely spotted white on the underparts. There is a white stripe over the eye and the tail is blackish. The first Guyana specimen, collected on July 24, 2004, had a smooth ovary measuring 4x3 mm, a bursa of Fabricius measuring 3x3 mm, and an unossified skull (as often seen in Furnarioidea even when adult).[3] The song is an accelerating trill, lasting for about five seconds. EcologyIt inhabits dense undergrowth near streams, particularly in humid premontane and montane forest,[3] foraging on the ground for insects and other invertebrates.[4] It usually occurs alone or in pairs and is often shy and hard to see. The nest is ball-shaped with a side-entrance and is built on the ground. Due to its extremely wide range, the sharp-tailed streamcreeper is not considered a threatened species by the IUCN.[1][5] SubspeciesThere are six subspecies which differ little:
The species has long been suspected to have at least a temporary presence in Guyana. However, this was only proven recently, with sight records in the Pakaraima Mountains since 2002 and a specimen (LSUMZ 175389) taken in 2004. These birds probably belong to one of the Venezuelan populations, but it is not yet known to which.[6] Footnotes1. ^1 {{IUCN|id=22702732 |title=Lochmias nematura |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} 2. ^Remsem, (2003) 3. ^Salaman et al.
