(Fig. 9)

Collaria nigra Linnavuori, 1975: 17 [n.sp.]; Schuh 2002–2014 [catalog].

Diagnosis. Distinguished by the general coloration predominantly black with brownish areas and by the pale color in the humeral regions of pronotum (Fig. 9).

Redescription. Male: COLORATION: Black. Head: Black, longitudinal sulcus with V-shaped median spot behind it and triangular lateral spot behind both eyes ochraceous; eye yellow; mandibular plate, maxillary plate and apex of buccula black; labium brown with black apex; clypeus black; frons brown with a black adjacent part; antennal segments dark brown, with segment I pale with dark brown apex. Thorax: Pronotum and collar dark; calli and anterior lateral margins pale brown; inner region of calli black; proepisternum black; scutellum black. Hemelytra black; embolium and external region of cuneus, pale; internal margin and medial cuneus and hemelytral membrane, dark brown; ostiolar peritreme pale brown, abdomen black with yellowish spots. VESTITURE AND STRUCTURE: Head: Antenna with short pilosity; length equal to thickness of segments; segment I approximately equal to width of head (Table 1), twice width of II; segment II 3 times longer than I (Table 1). Thorax: Pronotum with anterior lobe gradually narrowed with prominent humeral angles, lateral margin carinate and golden long sparse and erect pilosity. MEASUREMENTS: See Table 1.

Female: Unknown.

Geographic distribution. Known only from Oromiya Kilil, Ethiopia (Fig. 107) (Linnavuori 1975).

Plant associations. Unknown.

Discussion. Collaria nigra is similar to C. villiersi based on the dark coloration (Fig. 1), but this species is easily separated from C. villiersi by having lateral margins of pronotum pale brown and black hemelytra. Only the holotype (male) was located, and the genitalia were not dissected.

Examined material. Type material: Holotype: 1 ³ ETHIOPIA: Oromiya Kilil, [Shashamanni: Wondo Cloud Forest: 7°12'0''N; 38°36'0''E], 8.vi.1963, R.Linnavouri (AMNH).
