Holotype. Male. PAPUA NEW GUINEA: Bougainville Is., Mutahi, elev. 1100 m, [5° 33' S, 155° 2’ E], 15 February 1968, coll. Tawi Bukam. Deposited in Bernice P. Bishop Museum. GoogleMaps

Diagnosis. Testaceous with metallic green and white maculations. Labium reaching sixth abdominal sternite (fifth visible). Profemora with no series of tubercles. Ventral rim of pygophore with narrowly bilobed process. Medial penile plates medially with large tubercle and 1.5x longer than broad. Eighth gonocoxae of female deeply emarginate along posteromedial margin.

Description. Body about 2X longer than broad ( Fig. 28G View FIGURE 28 ). Head slightly longer than broad; juga shorter than tylus. Pronotum with anterior margin concave; anterolateral angle produced laterally as a small tubercle; anterolateral margins crenulate, carinate anteriorly; lateral angles produced into acute angle; posterior margin slightly concave. Scutellum with lateral margins scarcely becoming parallel prior to apex. Bucculae with anteroventral angle acute, produced anteroventrally. Labium reaching sixth abdominal sternite (fifth visible); ratios of labial segments 1:1.7:2.1:1. Peritreme 1/3 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 through fifth visible) sulcate. Femora unarmed.

Color. Ground color testaceous with metallic green and white maculations. Antennal segment I dorsolaterally castaneous; segments II–V castaneous, sometimes testaceous basally. Pronotum with anterior portion testaceous with metallic green punctations, posterior portion creamy between metallic green punctations. Scutellar bulge dark/green metallic; anterolateral excavations black; median longitudinal ridge testaceous. Forewing with mottling of ground color and creamy maculations; membrane testaceous. Labium straminous to testaceous, apical portion of labial segment IV castaneous. Legs of ground color; tubercles on profemora castaneous; distal portion of tibiae darker than remainder; tarsi distally and ventrally dark. Venter of abdomen castaneous; labial sulcus testaceous.

Male. Pygophore constricted around bases of dorsolateral lobes ( Fig. 32A–C View FIGURE 32 ). Ventral rim with median narrowly bilobed process ( Fig. 32A View FIGURE 32 ). Anterior flange of dorsolateral lobes developed as small rounded carina, convexity directed dorsolaterally ( Fig. 32B, C View FIGURE 32 ); posterior lobes absent; posteroventral lobes apically acute, directed laterally ( Fig. 32A–C View FIGURE 32 ). Medial penile plates 1.7X longer than broad, slightly swollen distally, medially with large tubercle ( Fig. 34C View FIGURE 34 ).

Female. Laterotergites of eighth segment broad, laterally with rounded lobes. Gonocoxa of eighth segment deeply emarginate on posterior margin. Gonocoxa of ninth segment narrow; posterior margin abruptly sinuate. Laterotergites of ninth segment subtriangular, rounded apically ( Fig. 36I View FIGURE 36 ). Secondary thickening of vagina intima tubular, 4–5X longer than broad, pore to ductus recepticali opening at apex.
