HOLOTYPE: PAPUA NEW GUINEA: Morobe: Wau , 7.3333 ° S 146.71667 ° E, 1100 m, 14 Aug 1972, G. G. E. Scudder, Light Trap, 13 ( AMNH _ PBI 00053250 ) ( BPBM).

DIAGNOSIS: Differentiated from similar taxa by characters listed in generic diagnosis and contiguous red line along dorsal margin of propleuron; genital capsule with lateral tubercle; aedeagus with relatively large, serrated, hatchetlike lobal sclerite ( fig. 5e ). Females with short setae on posterior margin of corium.

DESCRIPTION: Coloration ( fig. 1d ): Head yellowish brown with red maculations on clypeus and mandibular plates; gula suffused with blue-green. Antennae yellowish brown becoming darker distally. Prothorax yellowish brown, tinged with green; disc with dorsal red medial stripe; collar red; dorsal margin of propleuron with red stripe along length, suffused with blue ventrally. Scutellum bluegreen with medial triangular red maculation on anterior margin. Hemelytra predominately yellowish brown with red maculation along anterior cuneal margin; margin of clavus suffused with red along commissure and scutellar margin; cuneus narrowly margined with red. Abdomen yellow with dorsal surface of male genital capsule dark brown. Legs predominately yellow becoming brown distally, ventral surface suffused with blue-green; metafemur with pale brown spots on anterior surface and red distally. Structure: As in generic description with the following additions. Head with relatively deep distinct sulcus along length of vertex and frons; basal fourth of antennal segment II with series of 12–17 short hairs oriented perpendicular to antennal surface ( fig. 3b ). Small cell of hemelytral membrane greater than one-half length of cuneus. Genitalia ( fig. 5 ): Genital capsule roughly cylindrical with large opening and large tubercle on left lateral surface; ventral projection of ventral margin asymmetrical to right side, subquadrate; dorsal projection of ventral margin asymmetrical to right side, auriculate with sharp stout process on left margin. Parameres as in generic description. Theca sclerotized basally, distally convoluted into several large flanges. Aedeagus with large hooked and elongate, serrated, hatchet-shaped lobal sclerites.

FEMALES: Similar to males. Basal portion of antennal segment II undifferentiated from remainder. Genitalia: Ovipositor as in generic description. Vestibulum convoluted with complex paired in-foldings; sclerotized rings large, weakly sclerotized, laterally folded for entire length, more than twice as long as broad, aperture irregular; dorsal labiate plate convoluted medially with lateral weakly sclerotized in-foldings; posterior wall with paired interramal sclerites; interramal lobes (K-structures of Slater 1950) one-fifth the length of the ovipoister, semicircular, distinctly spinulose.

MEASURMENTS: Males (N 5 2): L-Tot 6.12–6.57, Cly-Cun 4.42–4.75, L-Hd 0.52– 0.55, L-Prn 0.92–0.96, L-Sct 0.64–0.71, L- Cun 1.03–1.10, W-Hd 0.81–0.87, W-Prn 1.33– 1.38, W-Sct 0.65–0.69, IOD 0.37–0.45, L-AI 0.99–1.01, L-AII 3.21–3.30, L-AIII 1.69–1.77, L-AIV 2.09–2.09, L-mtf 3.20–3.47, L-mtt 5.78–6.07.

ETYMOLOGY: Named for the spectacular male genitalia and relatively bright coloration of this species.

HOSTS: No known hosts, collected at light traps.

DISTRIBUTION: Eastern New Guinea.
