( Figs 5–6 View Figs 1–9 , 19 View Figs 19–21 )
Type material. HOLOTYPE: J, ECUADOR: TUNGURAHUA: Baños , 1900 m, 29.iv.1930, W. M. Clarke Macintyre ( USNM) . PARATYPE: 1 J, same data as holotype ( UNAM).
Description. Male (holotype). Dorsal coloration ( Fig. 5 View Figs 1–9 ). Head dark orange with upper margin of postocular tubercle, two irregular stripes running lateral to midline, ocellar tubercle, and vertex dark brown; inner surface of antenniferous tubercle pale yellow; antennal segment I pale yellow, II–III pale yellow with apical third pale castaneous, and IV with basal half dark brown, and apical half pale castaneous; antennal segments I to III with scattered pale red granules; pronotum, scutellum, clavus and corium dark brownish black with posterolateral and posterior border of pronotal disk, lateral border and apex of scutellar disk, inner border of clavus including the claval commissure and the costal border of corium dark yellow ochre; hemelytral membrane brown with veins darker; upper margin of connexival segments III– VI yellowish orange, and inner margin brown with anterior and posterior border yellowish orange; segment VII brownish black with posterior border yellow; abdominal segments black.
Ventral coloration ( Fig. 6 View Figs 1–9 ). Head including the bucculae pale creamy yellow, with outer margin, including the postocular tubercle and juga shiny black; rostral segment I pale creamy yellow, II–IV yellowish orange (apex of IV brown); thorax shiny black with wide creamy yellow stripe that covers the acetabula and the anterior and posterior lobes of metathoracic ostiolar peritreme; pro-, meso-, and metasternum dark brown; legs pale yellowish orange; femora with scattered pale red granules; abdominal sternite III–VI with wide creamy yellow stripe delineated on the sides by a wide shiny black longitudinal stripe; middle third of abdominal sternite III–V and anterior margin of VI with dull brownish stripe; sternite VII shiny black with anterior margin yellow; pleural margins III–VII dark yellow; rim of abdominal spiracle brown; male genital capsule shiny black.
Structure. Body slightly flattened dorsoventrally. Head. Antenniferous tubercles unarmed; rostrum reaching posterior border of mesosternum. Thorax. Pronotum: anterior angles unarmed, rounded, not exposed; anterolateral margins crenulate, with humeral border smooth; humeral angles slightly expanded laterally; posterolateral borders with outer third crenulate, and inner third smooth; posterior border straight, smooth; triangular process absent; legs unarmed. Genital capsule. Posteroventral edge with wide “V”-shaped concavity at middle third ( Fig. 19 View Figs 19–21 ).
Measurements (mm). Total body length 10.78. Head length 1.36; width across eyes 1.68; interocular distance 0.94; interocellar distance 0.40; preocular distance 0.83; antennal segments: I – 1.60, II – 2.04, III – 1.80, IV – 1.88. Pronotal length 2.24; maximum width across humeral angles 4.12. Scutellar length 1.28; width 1.44.
Female. Unknown.
Differential diagnosis. This new species runs to couplet 52 in the key of BRAILOVSKY (1985) and shares with A. discifera from Colombia and Venezuela and A. flavovittata from Costa Rica and Panama, the unarmed antenniferous tubercles and femora; thorax and abdominal sterna provided with a wide creamy yellow stripe that covers the acetabula and is delineated on the sides by a wide or narrow shiny or dull black or pale orange longitudinal stripe; head dorsally without two black, complete longitudinal stripes; anterolateral margins of pronotum finely crenulated; antennal segments II–III yellowish orange without black rings; femora of the three pairs of legs concolorous and never with black discoidal patches; and humeral angles slightly exposed laterally. In A. crinita the color of the pronotum, scutellum, clavus and corium are mostly entirely dark brownish black; the thorax and abdominal sterna creamy yellow and laterally delineated by a wide, shiny black longitudinal stripe; abdominal sternite VII is shiny black with anterior margin yellow; the dorsal abdominal segments III–V are black; the anterior angle of pronotal disk unarmed, rounded; and the hemelytral membrane brown with veins darker. In A. discifera and A. flavovittata the color of the pronotum, scutellum, clavus and corium are mostly pale yellowish orange with punctures reddish brown; and having the anterior angle of pronotal disk armed with a short acute spine. In A. discifera , the thorax and abdominal sterna are creamy yellow, delineated on the sides by a slender dull brownish black longitudinal stripe, and the abdominal sternite VII is yellow or with a tiny black spot. In A. flavovittata , the thorax and abdominal sterna are creamy yellow to yellow and laterally delineated on the sides by a wide, pale orange longitudinal stripe, the abdominal sternite VII is entirely yellow, dorsal abdominal segments III–V yellow, and hemelytral membrane pale brown with dark brown discoidal spots irregularly scattered.
Etymology. The species epithet is the Latin adjective crinitus (- a, - um), meaning hairy, longhaired, in reference to the short setae that irregularly cover its dorsal surface.
