This species is considered Endangered because it has a very small range, being currently known from only five sites and appears to have been lost from parts of its former range, suggesting that the population and possibly the area of occupancy are declining. In this context, the species's rarity indicates that the population may well be very small and comprised of extremely small, fragmented subpopulations.

|Range Description:||Taphrolesbia griseiventris occurs in the Andes of north-central Peru, where it is known from nine localities, on the Pacific slope in Cajamarca, and in the río Marañón drainage in Cajamarca and Huánuco. There have been very few records since 1950: in Cajamarca, two males where the main road from Cajamarca to the coast crosses to the Pacific slope, in the early 1990s (B. P. Walker in litt. 1997); a female feeding nestlings in February 1999, near the río Chonta, south-east of Cajamarca (Garrigues 2001); a female nest-building above Sucre, south-west of Celendín in February 1999 (Garrigues 2001); in Huánuco, near Cullcui in 1983 (where it was also recorded in 1922) (T. S. Schulenberg in litt. 1994); three or more seen at the bridge where the Huánuco-La Unión road crosses the río Marañón, in 1975 (but not subsequently, despite several searches) (J. P. O'Neill in litt. 1997, W-P. Vellinga in litt. 1997) and three nests near Cajamarca in February 2001, two again occupied in December 2001 (J. Flanagan in litt. 2002). It was been reported in 2006 from Marcabalito, La Libertad (R. Zeppilli per F. Angulo in litt. 2012), and has been seen close to Llanganuco lake, Ancash (Angulo in litt. 2012). Two collecting localities near Cajamarca and one near Cajabamba have produced the greatest number of specimens, but the species has not been seen at any of these sites recently.|
