( Figs 9 View Figs 1–9 , 21 View Figs 19–21 ) Type material. HOLOTYPE: J, ECUADOR: ORELLANA: Napo, Loreto, 500 m, 15.1.1995, A. Moscoso (UNAM). PARATYPES: 2 JJ 2 ♀♀, ECUADOR: without locality, (“summer”) 1965, C. R. Patrick (AUNH, UNAM).
Description. Male (holotype). Dorsal coloration. Head, including antennal segments I–III, and anterior lobe of pronotal disk pale yellowish orange; antennal segment IV yellow with basal third pale brown; posterior lobe of pronotal disk dark orange, punctures reddish brown and humeral angles dark brown; scutellum, clavus and corium dark orange, punctures reddish brown, costal border and veins paler; hemelytral membrane pale brown; connexival segments III–VI pale yellow, VII with anterior half pale yellow and posterior half pale brown; dorsal abdominal segments III–VI shiny orange, VII dark brown with anterior margin and lateral areas shiny orange.
Ventral coloration. Head including rostral segments (apex of IV pale brown) and legs pale yellowish orange; thorax pale yellowish orange, punctures pale reddish orange; anterior and posterior lobes of metathoracic ostiolar peritreme pale yellow; abdominal sternites III–VI pale yellowish orange, VII pale brown with lateral areas pale yellowish orange; pleural margins of abdominal sterna III–VII yellow; abdominal spiracles with yellowish orange rim; genital capsule black with dark orange marks.
Structure. Head. Antenniferous tubercles armed with a short acute spine; rostrum reaching posterior margin of mesosternum. Thorax. Pronotum: anterolateral margins uniformly nodulose; posterolateral margins sinuate, smooth; posterior border straight; triangular process short, rounded, convex, not clearly exposed; anterior lobe rounded, without conical expansion; humeral angles expanded on a medium sized rectangular process, directed outward and upward, apically truncated with borders uniformly nodulose. Legs. Femora armed with two tiny subapical spiniform tubercles. Genital capsule. Posteroventral edge with small “V”-shaped concavity at middle third ( Fig. 21 View Figs 19–21 ).
Measurements (mm). Total body length 11.13. Head length 1.32; width across eyes 1.64; interocular distance 0.98; interocellar distance 0.46; preocular distance 0.75; antennal segments: I – 2.36, II – 2.64, III – 2.56, IV – 2.24. Pronotal length 2.36; maximum width across humeral angles 4.45. Scutellar length 1.36, width 1.44.
Female ( Fig. 9 View Figs 1–9 ). Color and habitus similar to male holotype. Connexival segments III–VI yellow with inner margin pale brown, VII with anterior half yellow and posterior half pale brown, VIII–IX dark brown to black; dorsal abdominal segments III–VI dull orange, VII dull orange with posterior border black, VIII–IX black; genital plates dark orange with diffuse dark brown marks.
Measurements (mm). Total body length 13.18. Head length 1.28; width across eyes 1.68; interocular distance 1.00; interocellar distance 0.44; preocular distance 0.75; antennal segments: I – 2.16, II – 2.56, III – 2.64, IV – 2.24. Pronotal length 2.64, maximum width across humeral angles 4.85. Scutellar length 1.52, width 1.64.
Differential diagnosis. Very similar to A. rapax ( Fig. 13 View Figs 10–18 ) by having antennal segments I–III pale to dark yellowish orange and IV yellow with basal third pale brown; antenniferous tubercles armed with short spine; femora armed; and posteroventral edge of male genital capsule with V-shaped concavity at middle third. The humeral angles on each species are expanded and rectangular but in A. rapax they are conspicuously more expanded ( Fig. 13 View Figs 10–18 ), and the connexival segments III–VI are dark orange with upper angle and anterior third yellow. In A. humerata sp. nov., the expansion of the humeral angles is shorter ( Fig. 9 View Figs 1–9 ) and connexival segments III–VI are uniformly yellow (yellow with inner margins pale brown in females). Etymology. The species epithet is the Latin adjective humeratus (- a, - um), meaning shouldered, given in reference to the distinct development of the humeral angles of pronotum. Distribution. Ecuador.
