Holotype. PAPUA NEW GUINEA: Bougainville Is., Kokure, elev. 690 m, [6° 25' S, 155° 43’ E], 8–12 June 1956, coll. E. Ford. Deposited in Bernice P. Bishop Museum. GoogleMaps

Diagnosis. Distinguished by piceous coloration and male pygophore with distal margin with quadrate emargination. In females the posterior margin of the ninth gonocoxae is straight to slightly concave.

Description. Body 2X longer than broad ( Fig. 2D View FIGURE 2 ). Bucculae with anteroventral margin rounded. Labium elongate; ratios 1:1.7:1.5:0.9. Pronotum with anterolateral margins crenulate, explanate. Lateral margins scutellum becoming briefly parallel prior to apex. Mesosternum slightly convex. Spines of profemora 7–8 in number. Metafemora unarmed.

Color. Ground color bronze to piceous with some straminous and testaceous areas. Antennal segments I– III entirely castaneous, segment IV testaceous. Pronotum almost entirely bronze. Scutellum with three creamy maculations on anterolateral corners and apex, anterolateral excavations black. Membrane testaceous. Labium straminous to testaceous, apical portion of segment IV castaneous. Venter of abdomen pale with dark spiracles. Legs testaceous; tubercles of profemora castaneous.

Male. Ventral margin of pygophore bilobed ( Fig. 25D View FIGURE 25 ). Basal sclerite of proctiger roughly circular in outline, less than half as long as dorsolateral lobes ( Fig. 25F View FIGURE 25 ). Proctiger apically with quadrate emargination ( Fig. 25D View FIGURE 25 ). Tubercle of medial penile plates on center of disc ( Fig. 26D–E View FIGURE 26 ).

Female. Eighth gonocoxa roughly semicircular. Posterior margin of gonocoxa of ninth segment straight to slightly emarginated. Ninth laterotergites longer than broad, distally acute, surpassing posterior margin of eighth tergite ( Fig. 26F View FIGURE 26 ).

Measurements. Males (n=5): body length 15.8 SD 0.4 (15.4–16.6), anterior pronotal width 3.8 SD <0.1 (3.7–3.9), humeral width 7.8 SD 0.3 (7.3–8.1), scutellar length 5.9 SD 0.2 (5.5–6.1), medial length of sixth sternite (fifth visible) 0.9 SD <0.1 (0.8–0.9), medial length of seventh sternite (sixth visible) 3.0 SD <0.1 (3.0– 3.1). Females (n=5): body length 16.9 SD 0.3 (16.6–17.4), anterior pronotal width 3.8 SD <0.1 (3.7–3.9), humeral width 8.1 SD 0.2 (7.8–8.3), scutellar length 6.2 SD 0.1 (6.0–6.5), medial length of sixth sternite (fifth visible) 1.4 SD <0.1 (1.3–1.5), medial length of seventh sternite (sixth visible) 2.4 SD <0.1 (2.3–2.6). Appendages in Table 4.

Etymology. From the Latin trias— three and macula— stain or spot; in reference to the three pale spots in each corner of the scutellum.
