Etymology: The name refers to the irregular, yellowish macula on pronotum. Latin: ornatus, ornamentation.
Diagnosis: Dark brown with black punctures and light brown spots; transverse, irregular, light brown macula on pronotum, across humeri. Ventral thorax and abdomen black; legs lighter coloured, contrasting with body.
Head black; punctures confluent, forming dorsal wrinkles. Vertex tumid. Antennal segments brown, dorsum of segment Iand sometimes apex of segments IV–V light brown; proportional length of antennal segments: I> II <III> IV <V; third and fifth the longest, subequal. Margins and apex of juga ventrally yellowish. Bucculae with small anterior tooth. Rostrum dark yellowish, surpassing anterior margin of urosternite VII. Proportional length of labium segments: I <II> III <IV.
Pronotum bearing transverse, irregular, light brown macula across humeri; punctures sparse on macula, and forming shallow wrinkles posterior to cicatrices. Cicatrices slightly tumid, bearing a light brown middle spot. Anterolateral angles projected laterally, exceeding lateral limit of eyes by twice the ocellus width. Anterolateral margins slightly sinuous. Scutellum attaining middle of connexival segment V; punctures inconspicuous at apex; sometimes with irregular, small, light brown spots between punctures. Corium reaching middle of connexival segment VI, with irregular, small, light brown spots; punctures more dense on exocorium. Spot at apex of radial vein equals ocellus width. Membrane with ten to 13 veins, little surpassing apex of abdomen. Pleurae black with sparse, light brown spots; lateral margins of pronotum ventrally with light brown spots. Peritreme almost reaching lateral margin of evaporatorium. Legs dark yellowish, femora and dorsum of tibia with elliptical brown spots.
Connexivum with middle yellowish spot continued ventrally. Abdomen velvety, sparsely pubescent, with shallow punctures; trichobothrial tubercles black; few yellowish spots between spiracles and lateral margin of abdomen. Anteromesial margin of spiracles slightly elevated, concolorous.
Male. Measurements (N = 1): head length 2.06; width 2.60; pronotum length 2.65; width 6.57; scutellum length 4.46; width 3.38; length of antennal segments: I 0.78; II 0.31; III 1.86; IV 1.40; V 1.95; length of labial segments: I 1.60; II 2.80; III 2.30; IV 2.45; total length 12.15; width of abdomen 6.81.
Genitalia. Dorsal rim of pygophore concave; 1 + 1 obtuse projections near base of segment X, and 1 + 1 spine-like projections halfway between base of segment Xand posterolateral angles of pygophore. Inferior layer of ventral rim projecting lateral to segment Xover genital cup, perpendicular to the frontal plane of pygophore; projections spatulate, apex obtuse and light brown. Superior layer of ventral rim beneath the projection of inferior layer forming striations and lobes, appears membranous ( Fig. 4C View Figure 4 ). Median third of ventral rim concave. Ventral wall of pygophore with low median carina ( Fig. 4D View Figure 4 ). Lateral margins of segment X sinuous; apex covered with short setae ( Fig. 4C View Figure 4 ). Parameres placed ventral to segment X, projecting over the ventral rim of pygophore; head of parameres spatulate with dense, long setae ( Fig. 4D View Figure 4 ).
Female. Measurements (N = 4): head length 2.05 ± 0.12 (1.95–2.21); width 2.74 ± 0.04 (2.71–2.77); pronotum length 3.04 ± 0.29 (2.65–3.34); width 7.1 ± 0.16 (6.93–7.31); scutellum length 5.15 ± 0.17 (4.98–5.36); width 4.24 ± 0.23 (3.91–4.41); length of antennal segments: I 0.8 ± 0.06 (0.76–0.88); II 0.55 ± 0.03 (0.5–0.57); III 1.83 ± 0.07 (1.76–1.89); IV 1.43 ± 0.03 (1.39–1.45); V 2.05 ± 0.08 (1.95–2.14); length of labial segments: I 1.65 ± 0.08 (1.58–1.76); II 2.79 ± 0.14 (2.65–2.96); III 2.46 ± 0.09 (2.33–2.52); IV 2.55 ± 0.11 (2.46–2.71); total length 13.23 ± 0.47 (12.9–13.9); width of abdomen 6.96 ± 0.34 (6.67–7.46).
Genitalia. Gonocoxites 8 wider than long, disc uniformly convex, tumid posteriorly forming a flap; few setae on posterior third; transverse wrinkles more dense on lateral third; posterior margin subrectilinear, posterolateral angles as small tooth over the base of laterotergites 8; sutural angles forming obtuse projection over gonocoxites 9; basal two thirds of sutural margins slightly elevated ( Fig. 6D View Figure 6 ). Laterotergites 8 sparsely punctate at base; spiracles on low callus, posterior to lateral angle of gonocoxites 8 ( Fig. 6D View Figure 6 ). Gonocoxites 9 triangular with longitudinal suture; anterior margin emarginate ( Fig. 6D, F View Figure 6 ). Laterotergites 9 not surpassing the band connecting laterotergites 8; median margins on a higher plane than lateral margins, the latter narrow and deflected from basal angle almost to the apex; lateral basal angle depressed; anterior margin subrectilinear ( Fig. 6D, F View Figure 6 ). Gonapophyses 8 slightly sclerotized at base; lateral folds with conical microsculptures. Gonapophyses 9 with folds bearing conical microsculptures along lateral third of gonocoxites 9. Thickening of gonapophyses 9 in wide ‘V’. Chitinellipsen lateral to thickening of vaginal intima. Ductus receptaculi anterior to vesicular area wider than median duct of vesicular area. Length of vesicular area three times the combined length of pars intermedialis and capsula seminalis; base of median duct clavate; inner duct uniformly cylindrical. Tubular portion of ductus receptaculi posterior to vesicular area short, less than half length of vesicular area. Pars intermedialis long, at least four times longer than capsula seminalis; annular ridges convergent. Capsula seminalis hemispherical; projections long, slender, and twisted, sometimes bifid at apex, positioned at apex of capsula seminalis ( Fig. 6F View Figure 6 ).
Comments: Alitocoris ornatus sp. nov. is included in clade Ain a polytomy with the clade of Ali. schraderi ( Fig. 1 View Figure 1 ). It is included in Alitocoris until there is a better understanding of its phylogenetic position, and also based on general morphology, in particular because it shares with Ali. schraderi the apomorphic character states of the male and internal female genitalia, and with Ali. lateralis sp. nov. the apomorphic character states of laterotergites 9. The presence of a pronotal macula, the gonocoxites 8 sutural angles projecting over gonocoxites 9, and the lateral angles of gonocoxites 8 little projected over laterotergites 8 are unique characters of Ali. ornatus sp. nov.
