(Figs. 5, 55 C–D, 72)
Etymology. The name refers to the length of the humeral angles (L. brevis, short; L. cornu, horn).
Material examined. Holotype male. MEXICO, Tamaulipas: Rancho de Cielito 4 km W, 24–25-III-1980, E. G. Riley (TAMU).
Paratype. MEXICO, Tamaulipas: 1♀, Ocampo, Taylor Ranch, 7-VII-1972, M. Hooper (TAMU); Morelos: 1♀, Morelos, 21-VII-1954 (SEMC).
Measurements (n= 3). Total length: 16.9–19.4; head length: 1.5; head width: 3.5; pronotum length: 3.9–4.2; pronotum width: 11.7–13.0; scutellum length: 8.0–9.0; scutellum width: 7.0–7.3; abdominal width: 11.1–11.5; length antennomeres: I: 1.0; II: 1.5; III: 1.7–1.8; IV: 3.2; V: 3.5.
Diagnosis. Large (16.9–19.4 mm). Dorsal body surface olive green (Fig 55 C). Ventral surface dark yellow to orange with transversal smudged brown bands on thorax and abdomen (Fig. 55 D). Mandibular plates with the portion posterior to the lateral margin black (Fig. 55 C). Antennae yellow (Fig. 55 C–D). Pronotum with deep concolorous with the surrounding surface punctures; lateral margin crenulate (Fig. 55 C). Humeral angles very short (3.0 times wider than long); apex with black spot restricted to the angles in dorsal and ventral views (Fig. 55 C–D). Scutellum with concolorous with the surrounding surface punctures; apex not reaching the end of coria (Fig. 55 C). Coria with all veins yellow (Fig. 55 C). Connexival segments without spot (Fig. 55 C). Posterolateral angles of connexivum with apices light brown (Fig. 55 C). Ventral surface, thorax with brown bands; dark band of propleura covering 1/3 of the width of the sclerite (Fig. 55 D). Evaporatorium brown (Fig. 55 D). Metasternal process (Fig. 5 G) with arms of anterior bifurcation straight and laterally well expanded, margin acuminated at apex; anterior bifurcation broadly excavated receiving fourth rostral segment. Legs dark brown (Fig. 55 D). Abdomen with spine of segment III acuminated (Fig. 5 G). Intersegmental areas covered by wide smoky brown band with smudged margins, reaching lateral margin (Fig. 55 D). Pseudosutures smoky brown with irregular margins (Fig. 55 D). Median longitudinal brown band complete (Fig. 55 D). Trichobothria one in line with spiracle and the other laterad. Posterolateral angles of segment VII barely developed, not reaching the level of apices of laterotergites IX (Fig. 5 F). Male genitalia, dorsal side of the pygophore straight with smudged brown area occupying 2/3 of the surface (Fig. 5 A–B). Posterolateral angles of pygophore slightly developed (Fig. 5 A). Superior processes of the genital cup triangular, rising to the base, narrow, laminar, not continuing ventrally in a carina (Fig. 5 B, D–E). Parameres mainly brown; anterior lobe narrow and rounded; dorsal lobe large, acuminated and laterally curved; posterior lobe large, subrectangular and curved (Fig. 5 D–E). Proctiger, posterior face subelliptical, crenulate (Fig. 5 D–E). Ventral surface with dark spots in “V” (Fig. 5 C). Ventral rim with lateral subdistal tuft of setae (Fig. 5 A, C); with expansions undeveloped and concolorous with the surrounding surface (Fig. 5 C). Female genitalia, valvifers VIII subrectangular, concolorous with the surrounding surface punctures; posterior margin sinuous; sutural margins adjacent with small distal V-shaped excavation; mid-distal part with smoky brown spot. Laterotergites VIII with dark outer lateral margins, distal angles barely developed. Laterotergites IX with a large dark spot, apices rounded reaching the mediotergite VIII (Fig. 5 F).
Comments. Edessa (E.) brevicornis sp. n. resembles Edessa (E.) gentilitia Distant, 1890 (see Mendonça et al., 2023, Figs. 7 A–G, 26 A–F), and Edessa (E.) flavilinea sp. n.. The three species share very short humeral angles; connexivum without spots; evaporatorium brown; and pygophore with the superior processes of the genital cup without carina. Edessa (E.) brevicornis sp. n. and E. (E.) gentilitia have black humeral angles, while E. (E.) flavilinea sp. n. has brown humeral angles. Edessa (E.) brevicornis sp. n. differs from E. (E.) gentilitia by characteristics of the genitalia, the male of E. (E.) brevicornis sp. n. has the superior processes of the genital cup visible in posterior view (behind the parameres and visible in posterolateral view in E. (E.) gentilitia), and the dorsal lobe of the parameres less expanded (larger in E. (E.) gentilitia). In the female of E. (E.) brevicornis sp. n. the apices of laterotergites IX are rounded, while acuminate in E. (E.) gentilitia.
Distribution (Fig. 72). MEXICO: Tamaulipas, Morelos.
