Figs. 3A–C 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 ). 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 , 4B–C ). 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 ). 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 , 4A ). Vertex dorsally with paired large parallel yellow stripes, separated by conspicuous black area ( Fig. 3A ). Gena with black stripe behind compound eye ( Fig. 4A ). 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 ). FIGURE 3. Periphloea paraensis sp. nov. holotype ♀. A) habitus, dorsal view; B) idem, lateral view; C) idem, ventral view. 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 ). 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 ). Thoracic sterna smooth, mainly light-yellow with several conspicuous black and dark-brown stains ( Fig. 3C ). 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 ). 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 , 4B–C ). Costal area of posterior wing dark-brown, with light-yellow stains at posterior half ( Figs. 3A–B ); anal area light-brown. FIGURE 4. Periphloea paraensis sp. nov. holotype ♀.

Tergites I–VI dark-brown, VII–X dark-brown with light-yellow portions ( Fig. 3A ). 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 ). Sternite VI two times longer than wide ( Fig. 3C ). Sternite VII 2.2 times longer than wide, with slender aspect ( Fig. 3C ). 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 ). 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 ). Measurements (mm).
