Adult habitus. General body color yellow with patches of brown and black pigment. Ocellar area of head bearing a diffuse brown area of pigment ( Fig. 1 View Figure ). Median pronotal stripe dark, separated from wide, lateral stripe by an irregular yellow area; a few small yellowish areas are interspersed in the dark lateral bands. Femora banded; apical third dark and basal two thirds yellow; tibiae and tarsi dark brown. Wings brown, most veins darker, but costa and subcosta pale brown; r-crossvein on each wing darker than other veins.

Male. Forewing length 11–12 mm. Hammer thimble-shaped, height less than basal width ( Fig. 2 View Figure ). Aedeagal apex trilobed in dorsal and ventral aspect ( Figs. 3–4 View Figure ) and without subapical membranous lobes; median lobe much wider than lateral ones and bearing an obscure, median triangular notch. Aedeagal hooks slender; ventral keel obscure, consisting of a pair of short, thin ridges about twice as wide as the aedeagal hooks. Apex of aedeagus in lateral aspect somewhat foot-shaped ( Fig. 5 View Figure ).

Female. Forewing length 15–16 mm. Subgenital plate 4-lobed, outer lobes longer and wider than inner lobes ( Fig. 11 View Figure ); median notch deeper and wider than small lateral notches separating inner and outer lobes. Ninth sternum with a large posteríor membranous area; sclerotized region of sternum 9 with a V-shaped posteríor margin.

Larva. Unknown.

Etymology. The species name, used as a noun in apposition, is based on the Panamanian province in which it was collected.

Diagnosis. The new species keys to A. planicollis ( Klapálek, 1923) in Stark (1998)  but the ventral keel for that species consists of a single, more prominent median ridge, and the aedeagal apex for that species bears prominent membranous lobes It is also similar in size and color pattern to A. lineata ( Navás, 1924)  and might key to that species if the apicolateral aedeagal lobes are interpreted as being no more than “minute” ( Stark 1998).
