description: Collaria villiersi Carvalho, 1953
(Figs. 2, 4, 5, 6, 8, 9, 10, 11)
Collaria villiersi Carvalho, 1953: 3 [n.sp.]; Carvalho 1959: 286 [catalog]; Schuh 2002–2014 [catalog].
Diagnosis. Recognized by the fuscous to black coloration (Fig. 15), yellow lateral margins of collar; endosoma with smooth, oval medial left sclerite (Fig. 50), ventral right sclerite elongated, and dorsal right sclerite fusiform (Fig. 56); female genitalia with posterior wall with rounded interramal lobes (Fig. 105), medium dorsal structure, and median process shape as an inverted Y (Fig. 105).
Redescription. Male: COLORATION: Fuscous to black. Head: Dark brown with transversal pale spot (Vshaped) posterior to longitudinal sulcus; eye black; mandibular plate, maxillary plate and apex of buccula black; labium yellow with black apex; clypeus black; antennal segments brown and segment I pale. Thorax: Pronotum black; lateral margins of collar, yellow; proepisternum black; scutellum black. Hemelytra brown with a dark brown spot in median region; clavus embolium and pale anterior region of cuneus, internal margin of cuneus and hemelytral membrane, dark brown; ostiolar peritreme margins reddish. VESTITURE AND STRUCTURE: Head: Slightly broader than long, antenna with short erect pilosity; length of antennal segment I approximately two times width of head (Table 1), width two times II; segment II 2 times longer than I (Table 1). Thorax: Pronotum with anterior lobe abruptly narrowed, with lateral margin carinated and golden, sparse, erect pilosity.
MEASUREMENTS: Table 1. GENITALIA: Parameres: Left paramere sickle-shape ending in lateral tip with dorsal margin of basal sensory lobe almost straight and ventral margin of basal sensory lobe clearly convex; hypophysis with sharp lateral projection (Fig. 37), right paramere as in Fig. 37. Endosoma: Medial left sclerite oval and smooth (Fig. 50); ribbon like sclerite with short lobe or area beneath secondary gonopore covered with microtrichia (Fig. 50), ventral right sclerite elongated with trichia on surface and dorsal right sclerite fusiform with apex acute and with trichia on surface (Fig. 56).
Female: Similar to male in color and size, differing by yellowish color in abdomen. MEASUREMENTS: Table 1. GENITALIA: First gonapophysis: With acute apical grooved region (Fig. 71). Second gonapophysis: Apex triangular with one tooth (Fig. 81). Dorsal labiate plate with small sclerite caudal to sclerotized rings (Fig. 93). Posterior wall with rounded interramal lobes, and anterior angle narrow projected to a blunt tip (Fig. 105). Dorsal structure, medium, and medial process shaped as an inverted Y (Fig.105).
Geographic distribution. This species is known from Western Africa (Ivory Coast, Ghana, Senegal) (Fig. 107). (Schuh 2002–2014)
Plant associations. unknown.
Discussion. Collaria villiersi is similar to C.nigra in the uniform coloration of pronotum (Fig. 9), but is easily separated from C. nigra by the yellowish lateral margins of collar, endosoma with medial left sclerite oval, ventral right sclerite elongated, and dorsal right sclerite fusiform. Collaria villiersi was described by Carvalho (1953), but until now, the female and its genitalic structures remained unknown, in this work the female and genitalic structures were described for the first time.
