↑ 2,02,1C.J. Schofield, Cleber Galvão: Classification, evolution, and species groups within the Triatominae. Acta Tropica 110 (2009) 88–100. p. 89: The term ‘vinchuca’ widely used in Chile, Argentina and Uruguay, is derived from Quechua and typically translated as “he that lets himself fall”, perhaps referring to bugs falling from the house roof to reach their hosts below. In Peru, the widely used term is ‘chirimacha’, again from Quechua, usually translated as “drunk with the cold” and assumed to refer to the bugs’ dislike of very cold conditions (and absence from the high Andes).
