Diagnosis. Straminous to testaceous in color with black metallic markings. Labium reaching fifth abdominal sternite (fourth visible). Profemora with ventral series of tubercles. Ventral rim of pygophore with narrowly bilobed process. Medial penile plates unevenly carinate medially and 2x longer than broad. Eighth gonocoxae of female with deeply emarginate posterior margin.

Description. Body 2X longer than broad ( Fig. 28A View FIGURE 28 ). Head broader than long. Juga shorter than the tylus. Pronotum with anterior margin concave; anterolateral angle entire; anterolateral margins subentire (some vague crenulations anteriorly), explanate; lateral angles produced into an acute angle; posterior margin slightly concave. Scutellum with lateral margins becoming briefly parallel prior to apex. Bucculae with anteroventral angle acute, produced anteriorly. Labium reaching fifth abdominal sternite (fourth visible); ratios of labial segments 1:1.7:1.7:1. Peritreme less than 1/2 as long as distance from ostiole of metathoracic scent gland to lateral margin of metapleuron. Episternal ridge located 5/7 of distance between ostiole of metathoracic scent gland and lateral margin of metapleuron. Third through sixth abdominal sternites (second and fifth visible) sulcate. Profemora with ventral row of stout distally hooked spines; dorsal surface unarmed. Mesofemora with row of small ventral tubercles. Metafemora with row of small ventral tubercles.

Color. Ground color straminous to testaceous with black to metallic markings and punctations. Antennal segment I–II dorsolaterally testaceous; segments III–V with distal half castaneous. Pronotum with heavy metallic punctation. Scutellar bulge laterally bronze with medial straminous area; anterolateral excavations black; median longitudinal ridge straminous. Forewing with mottling of ground color and darker maculations; membrane testaceous. Labium straminous to testaceous, apical portion of labial segment IV castaneous. Legs testaceous with castaneous speckling; tubercles on profemora castaneous; tarsi distally and ventrally dark Venter of abdomen almost entirely castaneous; medial area castaneous, labial sulcus testaceous.

Male. Pygophore slightly constricted around bases of dorsolateral lobes ( Fig. 30A–C View FIGURE 30 ). Ventral rim with median narrowly bilobed process ( Fig. 30A View FIGURE 30 ). Dorsolateral lobes with anterior flange obscurely contorted or absent ( Fig. 30C View FIGURE 30 ); posterior lobes absent; posteroventral lobes rounded apically, directed laterally ( Fig. 30A– C View FIGURE 30 ). Medial penile plates narrow, 2X longer than broad, slightly emarginate distally, unevenly carinate medially ( Fig. 33A View FIGURE 33 ).

Female. Laterotergites of eighth segment broad, laterally with blunt lobes. Gonocoxa of eighth segment deeply emarginate on posterior margin. Gonocoxa of ninth segment broad; posterior margin entire. Laterotergites of ninth segment subtriangular, rounded apically ( Fig. 36A View FIGURE 36 ). Secondary thickening of vagina intima stout, hemispherical, pore to ductus recepticali opening at apex.
