Quechua, Chaupihuaranga

Ethnologue includes the dialect named in the title line in none of its Quechuan languages, which looks wrong.  The Peruvian linguist Alfredo Torero, whose 1964 classification of Quechua dialects is accepted still today (Los dialectos quechuas in: Anales Científicos de la Universidad Agraria, Vol. II, No. 4, Lima, 1964, pp. 446-478), divides his Quechua I group into eight dialects, one of which is 'Huayhuash medio' in Lima and Pasco.  Since 1964, administrative divisions in northern Lima have changed their names and boundaries, but what Torero writes about the geography of this dialect tells us that he refers to the location of Chaupihuaranga Quechua and the dialect named in the title line.  For Torero, this is one and the same dialect.  (Torero's five maps on how five representative phonemes are treated by the various Quechua I dialects, invariably put both areas in the same group.)  Just like Ethnologue suggests that Chaupihuaranga and Santa Ana de Tusi may be dialects of the same language, Torero says the same about Chaupihuaranga and Checras (Oyón).  Importantly, Glottolog (https://glottolog.org/resource/languoid/id/yana1272) in its References for Yanahuanca = Chaupihuaranga Quechua lists two works published in 1967 in Cuatro Fonologías quechuas: that on Yanacocha Quechua and that on Picoy Quechua -- the latter being spoken in the Checras area of Chaupihuaranga Quechua. (Interestingly, Torero also says that the neighboring Checras and Pacaraos speakers understand each other, although the speech of the former in his classification belongs to Quechua I and that of the latter to Quechua II. P. 472)  My estimate of the speaker population of the expanded Chaupihuaranga is 11,000 (8,000 for Chaupihuaranga proper and 3,000 for Checras, based on the 2017 census in Peru).
