Treatment

Edessa (Edessa) brevicornis sp. n.

( Figs. 5 View FIGURE 5 , 55 C–D View FIGURE 55 , 72 View FIGURE 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 View FIGURE 55 ). Ventral surface dark yellow to orange with transversal smudged brown bands on thorax and abdomen ( Fig. 55 D View FIGURE 55 ). Mandibular plates with the portion posterior to the lateral margin black ( Fig. 55 C View FIGURE 55 ). Antennae yellow ( Fig. 55 C–D View FIGURE 55 ). Pronotum with deep concolorous with the surrounding surface punctures; lateral margin crenulate ( Fig. 55 C View FIGURE 55 ). 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 View FIGURE 55 ). Scutellum with concolorous with the surrounding surface punctures; apex not reaching the end of coria ( Fig. 55 C View FIGURE 55 ). Coria with all veins yellow ( Fig. 55 C View FIGURE 55 ). Connexival segments without spot ( Fig. 55 C View FIGURE 55 ). Posterolateral angles of connexivum with apices light brown ( Fig. 55 C View FIGURE 55 ). Ventral surface, thorax with brown bands; dark band of propleura covering 1/3 of the width of the sclerite ( Fig. 55 D View FIGURE 55 ). Evaporatorium brown ( Fig. 55 D View FIGURE 55 ). Metasternal process ( Fig. 5 G View FIGURE 5 ) 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 View FIGURE 55 ). Abdomen with spine of segment III acuminated ( Fig. 5 G View FIGURE 5 ). Intersegmental areas covered by wide smoky brown band with smudged margins, reaching lateral margin ( Fig. 55 D View FIGURE 55 ). Pseudosutures smoky brown with irregular margins ( Fig. 55 D View FIGURE 55 ). Median longitudinal brown band complete ( Fig. 55 D View FIGURE 55 ). 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 View FIGURE 5 ). Male genitalia, dorsal side of the pygophore straight with smudged brown area occupying 2/3 of the surface ( Fig. 5 A–B View FIGURE 5 ). Posterolateral angles of pygophore slightly developed ( Fig. 5 A View FIGURE 5 ). Superior processes of the genital cup triangular, rising to the base, narrow, laminar, not continuing ventrally in a carina ( Fig. 5 B, D–E View FIGURE 5 ). 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 View FIGURE 5 ). Proctiger, posterior face subelliptical, crenulate ( Fig. 5 D–E View FIGURE 5 ). Ventral surface with dark spots in “V” ( Fig. 5 C View FIGURE 5 ). Ventral rim with lateral subdistal tuft of setae ( Fig. 5 A, C View FIGURE 5 ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 5 C View FIGURE 5 ). 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 View FIGURE 5 ).

Comments. Edessa (E.) brevicornis sp. n. resembles Edessa (E.) gentilitia Distant, 1890 (see Mendonça et al., 2023, Figs. 7 A–G View FIGURE 7 , 26 A–F View FIGURE 26 ), 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 .
