Description

The Utcubamba tapaculo is small compared to other tapaculos; it is approximately 11 cm (4.3 in) long. Males weigh 16.7 to 22 g (0.59 to 0.78 oz) and females 14 to 20 g (0.49 to 0.71 oz). The male is entirely black. The female is dark gray above and somewhat lighter gray below with little of no brown on the flanks.[2][1]

Taxonomy and systematics

The Utcubamba tapaculo was originally described as a subspecies of unicolored tapaculo (Scytalopus unicolor). Subsequent splits of two other subspecies retained it as a subspecies of blackish tapaculo. As of January 2021, the International Ornithological Congress (IOC) considers it a distinct species, but the Clements taxonomy retains it as a subspecies of blackish tapaculo (S. latrans intermedius).[1][3][4]

Distribution

The Utcubamba tapaculo is endemic to the central Andes of Peru. Most of the records are from the drainage of Río Utcubamba. The range extends from there west to Río Marañón, east to Río Huallaga, and south into San Martín. It is found in elevations from 2,560 to 3,600 m (8,400 to 11,810 ft).[1]

Status

The IUCN has not assessed the Utcubamba tapaculo.
