Chile. Region I Tarapacá: Usmagama, 15 Mar 1885, R.A. Philippi s.n. (lectotype, selected by Plos and Sancho (2013: 339): SGO [SGO044738!]; isolectotype: K [K000486664, photo!]).

Ophryosporus pinifolius has an inconspicuous pappus that consists of minute squamellae. Its leaves are extremely variable and range from linear-lanceolate with entire margins to irregularly dentate ones. It is one of two Andean species in the genus known to occur in Chile. Based on herbarium records, its distribution is centered in the northern regions of Tarapacá and Arica y Parinacota where it is widespread (Fig. 1 ).
