Type material. Phyllocnistis bourquini Pastrana, 1960 was described based on 15 males and 16 females, from Tigre, Argentina. The male holotype ( Fig. 3D ) is deposited in the Pastrana collection at MACN, with the following labels (separated by forward slash symbols, Fig. 4D ): / HOLOTYPUS / Tigre, Prov. BA VIII.9.57 Bourquin leg. / Phyllocnistis #m bourquini sp n. 1958 J. A. Pastrana det /. The female allotype and 21 paratypes (10 males and 11 females) are deposited also at MACN. The other specimens cited in the description, eight paratypes (four males and four females) are deposited in the Fernando Bourquin personal collection.

Forewing length. 2.70 mm (n=2).

Diagnosis ( Figs. 3D, S 1; Tab. 2). Dorsal forewing: ground color light gray. lf light yellow with dark brown borders, middle portion a little wider; this fascia emerges from proximal bases of the wing, running distally oblique to the inner margin, ending in the region II, where it is completely united to tf1. Transversal fasciae with same coloration as lf. The tf1 is broad, emerging on the costal margin and ending at lf. The tf2 is parallel and similar to tf1, emerges on the costal margin and reaches the inner margin; however, on the central region, it is partially interrupted by light grayish scales. The tf3 and tf4 cross the wing from the costal margin towards the inner margin; the tf4 is narrow and precedes as. P. bourquini is similar to P. baccharidis , differentiating from this species by the tied connection between lf with tf1 and by a complete separation between tf1 and tf2. In addition, by the shape of the two first fasciae morphology; that is, in P. bourquini the tf1 ends at the center of the wing and the tf2 reaches the inner margin, contrary to what is found in P. baccharidis .

Geographical distribution ( Fig. 5 ). Type specimens have distribution records for the city of Tigre , Buenos Aires province, Argentina.

Natural history. The specimens were reared by Fernando Bourquin, however, there is no information available for the immature stages in the original description.

Host plant(s). Tessaria integrifolia Ruiz & Pav. (Asteraceae) .

Examined material. Holotype and a paratype (allotype).
