Genitalia. Dorsal rim widely excavated with 1 + 1 spine projections directed towards the base of segment X. Inferior layer of ventral rim projecting lateral to segment Xover genital cup, perpendicular to the frontal plane of pygophore; projections spatulate, in dorsal view with an elevation midway between apex of projection and posterolateral angle of pygophore. Superior layer of ventral rim bent beneath the projection of inferior layer, forming a translucent, less sclerotized lobe, and looking almost membranous ( Figs 4AView Figure 4, 7BView Figure 7). Median third of ventral rim concave, emarginate ( Fig. 4BView Figure 4). Lateral margins of segment X sinuous; 1 + 1 lateral tuft of short setae; apex covered with fringe of long setae and narrowed from the base ( Fig. 4AView Figure 4). Parameres sinuous, slender, and lacking projections; head spatulate with obtuse apex, slightly curved ventrally; fringe of setae on lateral and apex of head; base flattened, with dense, short setae ( Fig. 5E– GView Figure 5). Parameres placed ventral to segment X, projecting over and little surpassing the ventral rim of pygophore ( Fig. 4B, DView Figure 4). Phallus. Phallotheca globose, lateral projection wide; ventral and dorsal apical processes short, little projected. Vesica long, pseudojointed and bent backward, surpassing the base of phalotheca; dorsal expansion at basal half of vesica ( Fig. 5A–DView Figure 5).

Female. Measurements (N = 15): head length 2.00 ± 0.07 (1.89–2.14); width 2.58 ± 0.07 (2.46–2.65); pronotum length 2.76 ± 0.11 (2.52–2.96); width 6.66 ± 0.26 (6.3–7.18); scutellum length 4.65 ± 0.2 (4.35–5.04); width 3.97 ± 0.17 (3.65–4.28); length of antennal segments: I 0.78 ± 0.04 (0.69–0.82); II 0.81 ± 0.07 (0.69–0.95); III 1.61 ± 0.09 (1.45–1.76); IV 1.49 ± 0.06 (1.39–1.58); V 1.82 ± 0.13 (1.58–1.95); length of labial segments: I 1.33 ± 0.07 (1.26–1.45); II 2.27 ± 0.11 (2.08–2.46); III 1.91 ± 0.16 (1.39–2.08); IV 1.70 ± 0.09 (1.58–1.83); total length 12.23 ± 0.45 (11.7–12.9); width of abdomen 7.11 ± 0.25 (6.7–7.5).

Genitalia. Gonocoxites 8 wider than long; posterior margins sinuous, concave medially, projected over the base of laterotergites 9; disc with median callus. Spiracles of laterotergites 8 on low callus, placed lateral to lateral angle of gonocoxites 8 ( Fig. 6AView Figure 6). Gonocoxites 9 with longitudinal suture; anterior margin subrectilinear ( Fig. 6A, EView Figure 6). Laterotergites 9 not surpassing the band connecting laterotergites 8; median margins on a higher plane than lateral margins; lateral basal angle flat; anterior margin slightly sinuous ( Fig. 6A, EView Figure 6). Gonapophyses 9 with conical microsculptures occupying lateral portion of posterior folds ( Figs 6EView Figure 6, 7AView Figure 7). Thickening of gonapophyses 9 in wide ‘V’. Chitinellipsen lateral to thickening of vaginal intima. Ductus receptaculi anteriorly to vesicular area wider than median duct of vesicular area. Length of vesicular area twice 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, not attaining half length of vesicular area. Pars intermedialis barrelshaped; at least four times longer than capsula seminalis; annular ridges convergent. Capsula seminalis hemispherical; projections long, slender, and twisted, sometimes bifid at apex, placed at base of capsula seminalis ( Fig. 6EView Figure 6).

Comments: Alitocoris schraderi  is in a clade with Ali. grandis  sp. nov. and Ali. lateralis  sp. nov. ( Fig. 1View Figure 1), and can be distinguished by the rostrum reaching the posterior margin of urosternite V, and antennal segment Vbeing the longest. Gonocoxites 8 of Ali. schraderi  bears a more tumid callus, and lateral angle more projected over laterotergites 9. The material examined in this study extends the distribution of the species to Honduras and Panama.
