How many tapaculos of the genus Scytalopus are there?

Well, many – according to a new study (which apparently took about 40 years in the making!!!).

The tapaculos of the genus Scytalopus are troughout small, mostly greyish colored, inconspicuous birds with poor flight abilities that inhabit the dense undergrowth of the Andean forests of southwestern South America (some species occur more northerly).

The Magellanic Tapaculo (Scytalopus magellanicus (J. F. Gmelin)) (see depiction below) is one of them, and is a part of a complex that shares its name, the Scytalopus [magellanicus] complex, which again includes several species, some of which have been discovered and described only recently.

Yet, this complex has gotten even richer in species, with the description of three completely new ones, split from others: the Jalca Tapaculo (Scytalopus frankeae), the White-winged Tapaculo (Scytalopus krabbei), and the Ampay Tapaculo (Scytalopus whitneyi), as well as one subspecies (itself only described in 2010) being elevated to species rank, the Eastern Paramo Tapaculo (Scytalopus androstictus).

Rufous Antpitta x six

The Rufous Antpitta is a more or less completely plain rufous-colored typical Antpitta that inhabits the dense forests of the Andes and their foothills from northern Bolivia to parts of southern Venezuela.

The bird reaches sizes from about 14,5 to 15 cm.

The species is split into six subspecies all of which are now about to be upgraded to species status, they will then probably be named as:

Bolivian Antpitta (Grallaria cochabambae J. Bond & Meyer de Schauensee)
Cajamarca Antpitta (Grallaria cajamarcae (Chapman))
North Peruvian Antpitta (Grallaria obscura Berlepsch & Stolzmann)
Rufous Antpitta (Grallaria rufula Lafresnaye)
Sierra Nevada Antpitta (Grallaria spatiator Bangs)
South Peruvian Antpitta (Grallaria occabambae (Chapman))

These future-former subspecies differ slightly in the the hue of their rufous-colored plumage, but very likely more so in their DNA.
