Edessa (Edessa) guatemalensis sp. n.

( Figs. 20 , 60 C–D , 72 )

Etymology. Named after the Country of the type locality of the species.

Material examined. Holotype male. GUATEMALA, Morales : Morales, XII-1929, J. J. White ( USNM).

Measurements (n= 1). Total length: 17.8; head length: 1.5; head width: 3.1; pronotum length: 3.5; pronotum width: 12.2; scutellum length: 8.5; scutellum width: 6.5; abdominal width: 9.8; length antennomeres: I: 1.0; II: 1.4; III: 1.7; IV: 3.5.

Diagnosis. Large (17.8 mm). Dorsal body surface olive green ( Fig. 60 C ). Ventral surface dark yellow to brown with transversal brown lines on thorax and abdomen ( Fig. 60 D ). Antennae reddish brown ( Fig. 60 C–D ). Pronotum with concolorous with the surrounding surface punctures ( Fig. 60 C ). Humeral angles very short (2.0 times wider than long); apex concolorous with the surrounding surface; curved backward ( Fig. 60 C ). Scutellum with concolorous with the surrounding surface to brown punctures; apex not reaching the end of coria ( Fig. 60 C ). Coria with all veins concolorous with the surrounding surface ( Fig. 60 C ). Connexival segments with concavities slightly covered by two black and small circular spots separated by a large yellow median spot ( Fig. 60 C ), spots extending ventrally, circular ( Fig. 60 D ). Posterolateral angles of connexivum with apices acute and black ( Fig. 60 C ). Ventral surface, thorax with brown narrow lines; dark line of the propleura covering 2/3 of the width of the sclerite ( Fig. 60 D ). Evaporatorium concolorous with the surrounding surface ( Fig. 60 D ). Metasternal process ( Fig. 20 F ) with arms of anterior bifurcation straight and laterally well expanded, margin acuminated at apex; anterior bifurcation broadly excavated receiving fourth and a small part of the third rostral segment. Legs with tibiae and tarsi reddish, remaining yellow ( Fig. 60 D ). Abdomen with spine of segment III rounded ( Figs. 20 F ; 60 D ). Intersegmental areas covered narrow black lines with well-defined margins, not reaching the lateral spots ( Fig. 60 D ). Pseudosutures concolorous with the surrounding surface ( Fig. 60 D , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 60 D ). Trichobothria one in line with spiracle and the other laterad. Male genitalia, posterolateral angles of the pygophore developed; projected laterally, apices with spots blacks ( Fig. 20 A–C ). Superior processes of the genital cup rectangular, thick, in flattened and coarse posterior view, continuing ventrally in a crenulate high carina ( Fig. 20 B, D–E , crenulate carina barely visible). Parameres ( Fig. 20 D–E ) with brown margins; anterior lobe rounded; dorsal lobe subtriangular, curved apex; posterior lobe inconspicuous and rounded. Proctiger, posterior face subelliptical ( Fig. 20 D–E ). Ventral rim with long setae but without a lateral tuft ( Fig. 20 C ); with expansions little developed, rounded, concolorous with the surrounding surface ( Fig. 20 C ). Female genitalia. Unknown.

Comments. Edessa (E.) guatemalensis sp. n. resembles E. (E.) simulata sp. n. and E. (E.) congrua Walker, 1868 (see Mendonça et al., 2023, Fig. 24 E–F ) by the humeral angles concolorous with the surface; connexival segments with two circular, black and small spots; coria with all the veins concolorous with the surface and body ventrally with intersegmental areas black. Edessa (E.) guatemalensis sp. n. differs by the humeral angles curved (the other species have humeral angles straight) and pseudosutures concolorous with the surrounding surface (the other species with pseudosutures black).
