Description. Male (holotype). Dorsal coloration. Ground color dark yellow, tubercles black and punctures dark reddish brown to dark orange; antennal segment I dark reddish brown suffused with dark orange, II and III with dorsal surface dark reddish brown to black and ventral surface dark reddish orange suffused with reddish brown to black spots, and IV dark orange with basal joint dark reddish brown; ocellar tubercle black; scutellum yellow, punctures, three quadrate spots at basal third and apex black; hemelytral membrane pale brown, veins slightly darker, and basal third pale yellow with white transversal vein ( Fig. 2 View Figs ); connexivum with anterior third yellow and posteriorly black with yellow spot near middle third; dorsal abdominal segments black. Ventral coloration. Ground color dark yellow with punctures black; rostral segments dark orange (apex of IV black); legs dark yellow, tubercles dark reddish brown, and densely covered with black discoidal spots; anterior and posterior lobe of metathoracic peritreme creamy yellow; abdominal sterna dark yellow, densely covered with black large spots, and with a clearly row of black discoidal spots lateral to middle line; lateral margin of abdominal sterna dark yellow, punctures black, and anterior third pale yellow; genital capsule dark yellow with black punctures.

Structure. Head. Antenniferous tubercle unarmed; rostrum reaching posterior border of mesosternum. Pronotum. Anterolateral margins gently nodulose to smooth; posterolateral margins sinuate, outer third slightly convex and gently nodulose, and inner third concave and smooth; posterior border almost straight; triangular expansion elongate and acute; frontal angles with broad conical expansion, directed forward; humeral angles slightly exposed ( Fig. 4 View Figs ). Legs. Femora with two short subapical spines. Genital capsule. Posteroventral edge with lateral angles exposed, shallowly convex, and conspicuously excavated in the middle third ( Fig. 6 View Figs ). Paramere. Figs. 9-10 View Figs .

Measurements (mm). Body length 12.30. Head length including the apex of tylus 1.25; width across eyes 1.55; interocular distance 0.85, interocellar distance 0.44; preocular distance 0.72; length of antennal segments: I, 1.85; II, 2.05; III, 2.14; IV, 2.00. Pronotum length 2.65; maximum width across humeral angles 4.60. Scutellar length 1.73; width 2.00.

Female. Habitus and color similar to male holotype. Connexival segments VIII and IX black with anterior third yellow; dorsal abdominal segments VIII and IX black; genital plates dark yellow, suffused with pink marks and with tubercles and punctures black.

Measurements (mm). Body length 13.84. Head length including the apex of tylus 1.45; width across eyes 1.65; interocular distance 0.92, interocellar distance 0.50; preocular distance 0.84; length of antennal segments: I, 1.90; II, 2.00; III, 2.10; IV, 2.05. Pronotum length 3.05; maximum width across humeral angles 5.00. Scutellar length 1.85; width 2.15.

Variation. i) Antennal segment IV shiny reddish orange with apical third shiny yellowish orange. ii) Hemelytral membrane whitish with veins darker.

Differential diagnosis. The new species has been placed in couplet 66-66’ of the BRAILOVSKY (1985) key, and is related to A. litigiosa Stål, 1862 , by having the apex of scutellum black, and abdominal sterna dark yellow, and densely suffused with black spots. In A. costalis Stål, 1870 , the apex of scutellum is yellow, and the abdominal sterna pale yellowish orange, scattered with black spots.

Anasa litigiosa , recorded from Mexico, and Guatemala, has the dorsal abdominal segments IV and V yellow, the hemelytral membrane brown with white discoidal spots ( Fig. 1 View Figs ), the femora unarmed, the triangular expansion of pronotum absent, and the posteroventral edge of male genital capsule weakly excavated at middle third ( Fig. 8 View Figs ). In A. stysi sp. nov., here recorded from southern Mexico, Guatemala, and Nicaragua, the dorsal abdominal segments IV and V are black, the hemelytral membrane pale brown to whitish without white discoidal spots, the femora armed with two subapical spines or tubercles, the triangular expansion elongate and acute, and the posterolateral border of male genital capsule with lateral angles exposed, shallowly convex, and conspicuously excavated at middle third ( Fig. 6 View Figs ).

Anasa maculipes Stål, 1862 , recorded from United States, Mexico, Guatemala, Honduras, and Costa Rica, also resembles A. stysi sp. nov. In A. maculipes dorsal abdominal segments III to VI are yellow, the hemelytral membrane dark brown, and antennal segments I to III pale reddish orange. In the new species the dorsal abdominal segments III to VI are black, the hemelytral membrane pale brown to whitish, and antennal segments I to III dark reddish brown to black and suffused with dark orange marks.

Etymology. Named in honor of the distinguished Czech entomologist Dr. Pavel Štys.

Distribution. Widespread in Mexico (Chiapas), Guatemala, and Nicaragua.
