Type material. The description of Phyllocnistis perseafolia Davis & Wagner, 2011  was based on ten males, eight females and five pupae from Villamaria, Colombia. The male holotype ( Fig. 3PView FIGURE 3) is deposited at USNMAbout USNM and has the following labels (separated by forward slash symbols, Fig. 4PView FIGURE 4): / HOLOTYPE Phyllocnistis perseafolia Davis & Wagner  #m / Genitalia slide By DRD USNMAbout USNM 34075 #m / COLOMBIA: Caldas Villa Maria Apr. 2008 F. Posada / HOST: Avocado. var. Hass leafminer /. According to the original description, the paratypes (nine males with one genitalia on slide ( USNMAbout USNM 34078) and eight females, with two genitalia on slides ( USNMAbout USNM 34076, 34077)) are deposited at USNMAbout USNM. Five pupae and one pupa on a slide mounted in glycerin ( USNMAbout USNM 34072) are deposited at the USNMAbout USNM and UNCMAbout UNCM collections.

Forewing length. 2.58 mm (n=1).

Diagnosis ( Figs. 3P, SView FIGURE 3 1; Tab. 2). Dorsal forewing: ground color silvery. lf faded, light yellow scales with brown border, emerging from the base of costal margin (region I), thus running convex towards the median region where it narrows, ending near tf l (region II). tf 1 and tf 2 fused, with same coloration as lf. The tf 1 is v-shaped, crossing the wing entirely, connecting to the central region of tf 2, which is short, restricted to the costal margin. A blotch is found on the distal region of the wing (III) formed by tf 3 and tf 4; on the tf 3 region the scales are light yellow and on the tf 4 they are darker. Strigulae typical for the genus. This species differs from all by the lf convex and tf 2 restricted to costal margin, connected to tf 1.

Geographical distribution ( Fig. 5View FIGURE 5). Specimens have distribution records for Villamaria, Caldas Department, Colombia. However, according to the authors, there might be chances of finding more specimens in the northern South America , where there is a greater number of the host plant cultivars. 

Natural history. Similar to the other Neotropical Phyllocnistis  , specimens of P. perseafolia  present thin serpentine mines, having a black fine trace of feces, either on the adaxial or abaxial leaf surface. Pupal development occurs in an elliptical chamber, slightly enlarged in the final portion of the mine. According to the authors, some mines were found on the avocado, the fruit produced by the host plant. The adults of this species usually emerge in April.

Host plant(s). Persea americana Mill., Hass  variety ( Lauraceae  ).

Examined material. Holotype.

Remarks. The authors figured and described in detail this species regarding the adults and pupa. Eggs and larvae were not examined.
