Chincha Quechua [qxc] Location and Speaker Population

The Location lines for Chincha Quechua [qxc] and Yauyos Quechua [qux] read practically the same, with the only difference being that the Yauyos Quechua Location line erroneously says 'northEAST Castrovirreyna province' when the Chincha Quechua Location line correctly says 'northWEST Castrovirreyna province.'  Now, your Dialects line for Yauyos Quechua lists districts in Lima and Ica departments but none in Huancavelica department.  Your map for Peru clearly shows that Chincha Quechua stays apart from Yauyos Quechua and to the east of the latter.  Alfredo Torero's, Willem Adelaar's, and Rodolfo Cerrón-Palomino's descriptions of the locations of Quechua dialects suggest that Chincha Quechua must be only present in northwest Castrovirreyna province, Huancavelica department, namely in its districts of Aurahuá (639 Quechua speakers according to the 2017 census), Arma (331 speakers), Chupamarca (231 speakers), Huamatambo (147 speakers), and Tantará (105 speakers).  The census data give us a total of 1,453 Quechua speakers, which may be rounded to roughly 1,500.  I am not sure if the neighboring San Juan district also belongs to the Chincha Quechua speaking area (I am inclined to think that it does not), but even if it does, it does not affect much the Speakers figure, as it only had 65 Quechua speakers according to the 2017 census, which, added to 1,453, gives us 1,518, rounded to the same 1,500.  The name Chincha, however, must be pointing at Chincha Province in the north of Ica Department, and we do see there a Quechua peasant community named Chavín in Chavín District, which is not mentioned among the Yauyos Quechua one-village varieties.  It is a 434-strong community, according to the 2017 census, and the same census says that Chavín District had 433 Quechua speakers in 2017.  There are also two peasant communities in San Juan de Yanac District, bordering on both Chavín District and Castrovirreyna Province; both communities speak mostly Spanish but do have 108 Quechua speakers, according to the same census.  We may thus safely estimate some 2,000 speakers of Chincha Quechua.  On the map then, it would be appropriate to draw the Chincha Quechua area immediately to the southeast and south of Yauyos Quechua, with no other language in between the two.
