( Figs. 36 , 65 E–F , 74 ) Etymology . The name refers to the black and yellow to orange color of the connexival segments (L. nigro, black; L. crocatus , saffronlike, saffron-yellow). Material examined. Holotype male. BRAZIL , Amazonas : S„o Gabriel , Rio Negro , 4-XII-1927 , J. F. Zikán ( CEIOC ). Paratype . BRAZIL , Amazonas : 1♀ , same data as holotype ( CEIOC ) . Measurements (n= 2). Total length: 21.9–23.7; head length: 1.5–1.9; head width: 3.5; pronotum length: 4.0– 4.4; pronotum width: 14.5–15.2; scutellum length: 10.9; scutellum width: 7.6–8.1; abdominal width: 12.5–14.0; length antennomeres: I: 1.0; II: 1.9–2.0; III: 1.9–2.0; IV: 4.4–4.5. Diagnosis. Large ( 21.9–23.7 mm ). Dorsal body surface reddish brown, densely punctured ( Fig. 65 E ). Ventral surface reddish brown with transversal black lines on thorax and abdomen ( Fig. 65 F ). Antennae reddish brown ( Fig. 65 E–F ). Pronotum with black punctures ( Fig. 65 E ); anterolateral margin and cicatrices with black punctures. Humeral angles short (1.5 times wider than long); apex with black spot expanding over the pronotal disc in dorsal view and restricted to the angles in ventral view; slightly curved backward ( Fig. 65 E–F ). Scutellum with black punctures; posterior part excavated medially; apex acute, not reach end of coria ( Fig. 65 E ). Coria with all veins concolorous with the surrounding surface ( Fig. 65 E ). Connexival segments with concavities entirely covered by rectangular black spots separated by a large yellow to orange median spot ( Fig. 65 E ), spots extending ventrally, triangular ( Fig. 65 F ). Posterolateral angles of connexivum with apices black ( Fig. 65 E ). Ventral surface, thorax with black lines; dark line of the propleura covering 2/3 of the width of the sclerite ( Fig. 65 F ). Proepisternum with dark line ( Fig. 65 F ). Evaporatorium concolorous with the surrounding surface; peritreme straight ( Fig. 65 F ). Metasternal process ( Fig. 36 G ) with arms of anterior bifurcation straight and laterally expanded at apex; anterior bifurcation broadly excavated receiving fourth rostral segment. Legs brown ( Fig. 65 F ). Abdomen with spine of segment III acuminated ( Fig. 36 G ). Intersegmental areas covered by narrow brown lines with smudged margins, not reaching the lateral spots ( Fig. 65 F ). Pseudosutures concolorous with the surrounding surface ( Fig. 65 F , dark lines are a deterioration of the exoskeleton). Median longitudinal brown band incomplete, restricted to the segment VII ( Fig. 65 F ). Trichobothria both parallel to the spiracle. Posterolateral angles of segment VII exceeding the level of apices of laterotergites IX ( Fig. 36 F ). Male genitalia, dorsal rim with margin straight ( Fig. 36 A ). Posterolateral angles of pygophore very developed, well projected laterally ( Fig. 36 A–C ). Superior processes of the genital cup thick, rectangular, flattened and coarse in posterior view, continuing ventrally in a crenulate high carina, ending in a developed dentiform projection ( Fig. 36 B, E , crenulate carina and dentiform projection barely visible). Diaphragm setulose ( Fig. 36 D–E ). Parameres ( Fig. 36 D–E ) with black margins; anterior lobe rounded; dorsal lobe subrectangular with curved apex; posterior lobe subrectangular. Proctiger, posterior face subelliptical ( Fig. 36 D–E ). Ventral rim with long setae but without a lateral tuft ( Fig. 36 C ); with expansions undeveloped and concolorous with the surrounding surface ( Fig. 36 C ). Female genitalia, valvifers VIII subrectangular, with concolorous with the surrounding surface punctures; sutural margins contiguous brown and not divergent; posterior margin in open U-shaped excavation and brown. Laterotergites VIII with one small dark spot on lateral margins. Laterotergites IX with apices rounded passing the mediotergite VIII ( Fig. 36 F ). Comments. See comments on E. (E.) flaviventris sp. n. . Distribution ( Fig. 74 ). BRAZIL : Amazonas.
