Collaria villiersi Carvalho, 1953 View in CoL

( Figs. 2, 4, 5, 6, 8 View FIGURES 1 – 8 , 9, 10, 11 View FIGURES 9 – 15 )

Collaria villiersi Carvalho, 1953: 3 View in CoL [n.sp.]; Carvalho 1959: 286 [catalog]; Schuh 2002–2014 [catalog].

Diagnosis. Recognized by the fuscous to black coloration ( Fig. 15 View FIGURES 9 – 15 ), yellow lateral margins of collar; endosoma with smooth, oval medial left sclerite ( Fig. 50 View FIGURES 38 – 50 ), ventral right sclerite elongated, and dorsal right sclerite fusiform ( Fig. 56 View FIGURES 51 – 56 ); female genitalia with posterior wall with rounded interramal lobes ( Fig. 105 View FIGURES 94 – 105 ), medium dorsal structure, and median process shape as an inverted Y ( Fig. 105 View FIGURES 94 – 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 View FIGURES 25 – 37 ), right paramere as in Fig. 37 View FIGURES 25 – 37 . Endosoma: Medial left sclerite oval and smooth ( Fig. 50 View FIGURES 38 – 50 ); ribbon like sclerite with short lobe or area beneath secondary gonopore covered with microtrichia ( Fig. 50 View FIGURES 38 – 50 ), ventral right sclerite elongated with trichia on surface and dorsal right sclerite fusiform with apex acute and with trichia on surface ( Fig. 56 View FIGURES 51 – 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 View FIGURES 62 – 71 ). Second gonapophysis: Apex triangular with one tooth ( Fig. 81 View FIGURES 72 – 81 ). Dorsal labiate plate with small sclerite caudal to sclerotized rings ( Fig. 93 View FIGURES 82 – 93 ). Posterior wall with rounded interramal lobes, and anterior angle narrow projected to a blunt tip ( Fig. 105 View FIGURES 94 – 105 ). Dorsal structure, medium, and medial process shaped as an inverted Y ( Fig.105 View FIGURES 94 – 105 ).

Geographic distribution. This species is known from Western Africa ( Ivory Coast, Ghana, Senegal) ( Fig. 107 View FIGURE 107 ). (Schuh 2002–2014)

Plant associations. unknown.

Discussion. Collaria villiersi is similar to C.nigra in the uniform coloration of pronotum ( Fig. 9 View FIGURES 9 – 15 ), 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.
