( Figures 4–7 View FIGURE 4 View FIGURE 5 View FIGURE 6 View FIGURE 7 )

Diagnosis: Head and metopidium black; in dorsal view, black area V-shaped, extended diagonally from humeral angles to dorsomedial carina above semicircular lateral impression. Forewing veins black and membrane on anterior area of apex smoky hyaline.

Description: Holotype male. Color: Head ochraceous black, with one yellow inverse T between ocelli (on epicraneal suture and dorsal margin of frontoclypeus), eyes silver, ocelli ochraceous yellow. Pronotum black from metopidium and diagonally from humeral angles toward dorsum over beginning of lateral impressions, and then bright yellow [in live specimens, this yellow area is green, see Fig. 1A–B View FIGURE 1 ]. Labium, thoracic pleurites and sternites, coxae and base of metathoracic femur black. Forewings smoky hyaline with black veins; one yellow band on sclerotized area of clavus; one darker macula between apex of M basal cell, first discoidal cell, second and third apical cell and adjacent area of apical limbus. Pro- and mesothoracic femora, tibiae and tarsomeres ochraceous brown; third tarsomeres with apex black. Abdomen dark brown ( Figs. 4 View FIGURE 4 , 5 View FIGURE 5 ).

Abdomen: Subgenital plates triangular and slender, bilobed after half-length, bearing a quadrangular process at apex in ventral view, and triangular in lateral view. Styles hook-shaped, relatively slender, shank broader at middle. Aedeagus U-shaped, several rows of minute teeth along entire anterior surface of posterior arm ( Fig. 6 View FIGURE 6 ).

Female. Same as male but larger. Abdomen: Gonoplac in lateral view with apex rounded, ventral outline widely arched, basal half distinctly narrower than apical half. First valvula blade-shaped, slender, dorsal outline widely arched upward; longitudinal dorsal axis on apical ¾ and apex ventrally ornate with oblique and lineal integumental processes, ramus extended up to apex, pores along ramus extension, ramus extended almost until apex, ventral sculptured area restricted to apex. Second valvula distinctly more sclerotized than first valvulae, dorsal outline widely arched upward, ramus extended almost until apex with pores along, canals at apical 1/3 extended toward rounded teeth which are only present on apical 1/3; two relatively more sclerotized teeth contiguous at base of apical 1/3, longitudinal ventral axis ornate basally with linear and oblique integumental processes, and apically with escamiform integumental processes ( Fig. 7 View FIGURE 7 ).

Nymph: unknown.

Measurements: Holotype male (mm): body length: 9.85; forewing length: 8.26; pronotal length: 8.12; pronotal height: 3.07; pronotal width: 3.78; head width: 3.38; vertex width: 2.29; vertex length: 1.36.

Biology. Two females were recorded on Erato vulcanica (Asteraceae) ( Fig. 1A View FIGURE 1 ) but only one was collected (designated here as the paratype). The holotype was collected on Acanthaceae ( Fig. 1B View FIGURE 1 ). Additional field data is required to determine whether these are legitimate host plant associations.

Examined material. Holotype male: COLOMBIA: Risaralda: Pueblo Rico: “COLOMBIA.

Notes on type series. Holotype minuten-mounted, in good state of preservation, with dissected abdomen placed in vial with glycerine pinned underneath the specimen. Paratype equally well preserved, minute-mounted, with dissected abdomen placed in vial with glycerine pinned underneath the specimen.

Distribution. COLOMBIA: Risaralda: Pueblo Rico (Vereda Montebello, PNN Tatamá— 1800–2350 masl) ( Fig. 8 View FIGURE 8 ).

Etymology. The epithet specific ‘ atromeris ’ refer to the words ‘ atra ’, which means black, and ‘ meris, ’ which means portion, to denote the unique coloration of the head and pronotum on the anterior half.

Remarks. This species is readily distinguished by its unique pronotal coloration, dark brown anteriorly and yellow beyond humeral angles ( Fig. 4 View FIGURE 4 ). The pronotal shape closely resembles A. pectoralis , except for a slightly lower dorsum and less pronounced suprahumeral horns. First and second valvulae exhibit some slight interspecific differences: in A. atromeris sp. nov. the prominent teeth of the second valvula are contiguous while in A. pectoralis they are separated by small teeth.

This species has only been found in one site of the Cordillera Occidental in Colombia (Western Andean Mountain range), while A. pectoralis was collected in different locations across the Cordillera Central in Colombia, in Macizo Colombiano, and in southern Ecuador and Peru ( Fig. 8 View FIGURE 8 ).
