Armitage, 1 ♀(  BPSC); same except, 8–12 May 2018, B. Armitage and K. Collier, 3 ♀ ( COZEM).  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). 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). Aedeagal apex trilobed in dorsal and ventral aspect ( Figs. 3–4) 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).  Female.Forewing length 15–16 mm. Subgenital plate 4-lobed, outer lobes longer and wider than inner lobes ( Fig. 11); 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). 1917355819 2018-02-18 COZEM B. and T.
