Type material. Phyllocnistis puyehuensis Davis, 1994 description was based on two males from Puyehue, Aguas Calientes National Park, Chile. The male holotype ( Fig. 3S ) figured is deposited at ZMUC, with the following labels (separated by forward slash symbols, Fig. 4S ): / HOLOTYPE Phyllocnistis puyehuensis Davis / CHILE, Osorno 16: Parque Nacional Puyehue, Aguas Calientes, 450 m, 12.xii.1981 Nielsen & Karsholt /. Paratype male with the same data of the holotype (ZMUC).

Forewing length. 2.65 mm (n=1).

Diagnosis ( Figs. 3S, S 1; Tab. 2). Dorsal forewing: ground color light gray. lf absent. tf1 fused to tf2, forming together a thicker golden yellow bar with dark brown borders that cross the wing entirely in the middle region (II).

They extend to the base of the wing as a fine, dark brown strip that is alligned with the costal margin. On the distal region (III) there is a second blotch of similar color, formed by fusion of tf3 + tf4. Costal and apical strigulae typical for the genus. A light gray stripe precedes the as. This species is different from all other Neotropical Phyllocnistis by the absence of lf, and presence of a brown line along the costal margin in connection with the fused tf1 + tf2.

Geographical distribution ( Fig. 5 ). This species is known from Puyehue National Park, Aguas Calientes, Osorno province, Los Lagos region, Chile at 450 m elevation, a region of the cold and humid Valdivian Forests, southern Chile.

Natural history. No information available.

Host plant(s). Unknown.

Examined material. Holotype.

Remarks. The author of this species illustrated only the male genitalia. Information regarding female genitalia, immature stages and biology were not provided.
