( Figs. 3 View FIGURES 1–7 , 10 View FIGURES 8–14 , 19 View FIGURES 15–22 )

Type material. HOLOTYPE female. THE REPUBLIC OF THE PHILIPPINES: West Visayas, Region Panay Island, Antique Prov., Culasi , IV-2018, col. I. Lumawig ( UGAG) . PARATYPE. THE REPUBLIC OF THE PHILIPPINES: West Visayas, Region Panay Island, Antique Prov., Culasi , IV-2018, col. I. Lumawig ( UNAM) 1 female .

Description. Holotype female. Dorsal colouration. Head, pronotum, scutellum, corium, clavus, and dorsal abdominal tergites III–IX black to dark brown, with grey punctures; antennomeres I–III black, IV yellow with basal and apical third black to pale brown; head with neck at each side with one pale orange discoidal spot; costal margin of corium castaneous orange; hemelytral membrane creamy yellow with inner angle black; connexival abdominal segments III–VII black with posterior margin dark yellow, and VIII–IX black. Ventral colouration. Head, thorax, abdominal sternites III–IX, and abdominal spiracles black to dark brown, with grey punctures; labial segment I dark yellow, II black with basal joint dark yellow and III and IV black; fore and mid legs black with trochanters dark yellowish orange; hind leg black with trochanters and short, narrow longitudinal stripe along anterior third of femora dark yellowish orange (some specimens with hind femora entirely black); pleural abdominal margins III–VII black with posterior margin dark yellow; genital plates including laterotergites VIII–IX black.

Structure. Head. Longer than wide; labium reaching anterior margin of abdominal sternite IV. Thorax. Pronotum with anterior angles produced anteriorly as short conical teeth. Scutellum. Wider than long. Hemelytra. Hemelytral membrane reaching anterior margin of abdominal segment IV. Legs. Ventral surface of femora armed with two subdistal short spines and a few scattered along the surface. Genital plates. Laterotergite IX slightly folded downward ( Fig. 19 View FIGURES 15–22 ).

Measurements (in mm). Female. Body length 13.10; head length 2.25; width across eyes 2.15; interocular distance 1.25; preocular distance 1.27; antennomeres length: I 2.00; II 3.05; III 2.15; IV 1.75; labial segments length: I 1.75; II 1.85; III 1.65; IV 1.65; pronotum total length 2.45; maximum width across humeral angles 2.95; scutellum length 1.10; scutellum width 1.20.

Male. Unknown.

Type locality. The Republic of the Philippines, West Visayas .

Etymology. The specific name complanus is a Latin adjective referring to the dorsal view, which appears slightly flattened.

Diffrential diagnosis. Closely related to C. milzae Brailovsky (1995) by having the antennomere IV yellow with basal and apical third black to pale brown; labial segment I yellow to shiny orange, and II black to dull brownish orange with basal joint dark yellow; connexival abdominal segments III–VII black to dark brownish orange with posterior margin yellow; and femora ventrally armed. In C. milzae , the hemelytral membrane is entirely white and reaches the posterior margin of abdominal tergite IV; the anterolateral margins of pronotum, the apex of the scutellum, and the costal margin of corium are shiny to pale orange with yellow reflections; anterior angles of pronotum obtuse, rounded; and hind femora with basal half yellow and apical half reddish brown. In C. complanus sp. nov., the hemelytral membrane is white with an inner angle black and reaching the anterior margin of abdominal tergite IV; the anterior angles are produced anteriorly, as short conical teeth; the hind femora black with narrow yellow longitudinal stripe, running along anterior third of dorsal surface; and pronotum and scutellum entirely black to dark brown.
