Figs. 3A–C View FIGURE 3

Etymology. The name of the species refers to the State of the collection site in which the species was found ( Brazil, State of Pará).

Examined material. Holotype ♀: Froelich, O, 05.vii.1986, Brazil, Pará, Eldorado dos Carajás, Igarapé Azul (UnB).

Diagnosis. Head with longest projection of vertex approximately 2.8 times longer than compound eye length, posteriorly oriented ( Fig. 4A View FIGURE 4 ). Tegmina with long black stripe at medial sector, reaching approximately 2/3 of wing; with faded light-yellow stain from approximately mid length of costal sector, curving towards anal sector; keel of the tegmina conspicuously undulated, apical-most projection widened ( Figs 3B View FIGURE 3 , 4B–C View FIGURE 4 ). Subgenital plate (sternite VIII) with apical margin gradually narrowing and curving; medio-apical portion slightly truncated; medial elevation conspicuously marked, light-yellow with dark-brown mediolongitudinal stripe, with widened aspect, 1.6 longer than widest point ( Fig. 4F View FIGURE 4 ).

Description ♀ (only known sex). General coloration dark-brown. Head. With few scattered granules; dorsally with paired rows of four dark-brown and light-yellow projections, with the longest approximately 2.8 times the length of compound eye, posteriorly oriented ( Fig 3A View FIGURE 3 , 4A View FIGURE 4 ). Vertex dorsally with paired large parallel yellow stripes, separated by conspicuous black area ( Fig. 3A View FIGURE 3 ). Gena with black stripe behind compound eye ( Fig. 4A View FIGURE 4 ). Antenna setose, mainly anteriorly dark-brown, posteriorly light-brown; from flagellomere 10 onwards with light-yellow stains. Compound eye light-yellow with dark-brown spots ( Fig. 4A View FIGURE 4 ).

Thorax. Thorax with several setae at ventral margin. Pronotum with light-yellow stains near head, at mid length and near mesothorax; having paired parallel rows of four projections at mid and posterior thirds ( Figs. 3A–B View FIGURE 3 ). Mesonotum dorsally with paired parallel rows of seven projections from base to nearly apex; projections with lightyellow portions; with several scattered granules and small light-yellow spots ( Figs. 3A–B View FIGURE 3 ). Thoracic sterna smooth, mainly light-yellow with several conspicuous black and dark-brown stains ( Fig. 3C View FIGURE 3 ).

Legs. All legs ventrally setose. Anterior femur dorsally and ventrally dark-brown with several light-brown spots, 1.3 times longer than mesonotum ( Figs. 3A, C View FIGURE 3 ). Anterior tibia and tarsus dorsally and ventrally dark-brown with light-yellow spots. Mid and posterior legs dark-brown with light-brown spots.

Wings. Tegmina with long black stripe at medial sector, reaching approximately 2/3 of wing; with faded lightyellow stain from approximately mid length of costal sector, curving towards anal sector; veins dark-brown and light-yellowed stained; keel of the tegmina conspicuously undulated, apical-most projection widened ( Figs 3B View FIGURE 3 , 4B–C View FIGURE 4 ). Costal area of posterior wing dark-brown, with light-yellow stains at posterior half ( Figs. 3A–B View FIGURE 3 ); anal area light-brown.

Abdomen. Tergites I–VI dark-brown, VII–X dark-brown with light-yellow portions ( Fig. 3A View FIGURE 3 ). Tergites and sternites longer than wide. Sternites parallel sided, with few minutes scattered inconspicuous setae, mainly light-yellow with several black dark-brown stains. Sternite II 2.2 times longer than wide ( Fig. 3C View FIGURE 3 ). Sternite VI two times longer than wide ( Fig. 3C View FIGURE 3 ). Sternite VII 2.2 times longer than wide, with slender aspect ( Fig. 3C View FIGURE 3 ). Subgenital plate (sternite VIII) with lateral margin straight, apical margin gradually narrowing; apex slightly truncated; medial elevation conspicuously marked, light-yellow with dark-brown medial stripe, widened, 1.6 longer than wide at widest point ( Fig. 4F View FIGURE 4 ). Gonapophysis 8 flattened, ellipsoid. Gonapophysis 9 with nearly same length of gonapophysis 8; elongated, conspicuously curved at setose posterior half. Paraproct long and wide, dorsoventrally flattened. Cercus laterally flattened, slightly narrowing at middle length, densely covered by long setae ( Fig. 4F View FIGURE 4 ).

Measurements (mm). Total body length (dorsally measured, from base of frons to tip of abdomen, excluding cercus): 84.3; anterior femur (dorsally measured): 13; length of tergites VII–X combined (laterally measured): 11.3; cercus: 2.5.
