Collaria improvisa Reuter, 1893: 208 View in CoL [n.sp.]; Carvalho 1959: 284 [catalog]; Schwartz 2008: 1179 [diag., morph.]; Schuh 2002– 2014 [catalog].
Diagnosis. Recognized by the head coloration ( Fig. 6 View FIGURES 1 – 8 ), antennal segment I two times the width of segment II; endosoma with medial left sclerite short and covered by trichia, right posterior sclerite smooth, and apex of dorsal right sclerite broad ( Fig. 51 View FIGURES 51 – 56 ).
Redescription. Male. COLORATION: Dark brown with black and pale yellow areas. Head: Brown, with a transverse V-shaped pale spot posterior to sulcus, two dark brown spots around antennal scape, two black spots on middle of vertex and on margin of neck; eye pale brown; mandibular plate, maxillary plate, and apex of buccula, black; labium brown with black apex; clypeus black; antennal segments black with antennal scape, pale. Thorax: Pronotum brownish with pale line reaching disc; calli and lateral margins pale-yellow; inner region of calli pale brown; two elongated black spots on humeral angles of disc; collar pale-yellow; proepisternum with pale spot on dorsal region, reddish on median region, and pale on margin. Scutellum black and brown with a longitudinal paleyellow line and pale apex. Hemelytra brownish; clavus dark brown; embolium, and external region of cuneus pale; internal margin of cuneus and hemelytral membrane dark brown. Ventral side: Black, ostiolar peritreme with pale brownish margins, abdomen yellowish with a black spot at apex of pygophore. VESTITURE AND STRUCTURE: Head: Antenna with dense pilosity longer than thickness of segments; segment I 0.9 times width of head (Table 1) and two times width of II; segment II, 2.5 times longer than I (Table 1). Pronotum: Anterior lobe gradually narrowed, glabrous and carinate lateral margin. MEASUREMENTS: See Table 1. GENITALIA: Pygophore triangular; apex semi-triangular ( Fig. 18 View FIGURES 16 – 24 ), with a projected left lateroposterior margin ( Fig. 18 View FIGURES 16 – 24 ). Parameres: Left paramere sickle-shaped ending in a 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.29 View FIGURES 25 – 37 ); right paramere as in Fig. 29 View FIGURES 25 – 37 . Endosoma: With medial left sclerite oval with microtrichia on surface ( Fig. 42 View FIGURES 38 – 50 ); ribbon like sclerite with a short lobe or area beneath secondary gonopore covered with microtrichia ( Fig. 42 View FIGURES 38 – 50 ), ventral right sclerite (vrs) elongated with smooth surface, dorsal right sclerite (drs) fusiform with apex broad and smooth ( Fig. 51 View FIGURES 51 – 56 ).
Female: Similar to male in color and size. MEASUREMENTS: Table 1. GENITALIA: First gonapophysis with apical grooved region strongly sclerotized and acute, ( Fig. 64 View FIGURES 62 – 71 ).Second gonapophysis apex triangular, striated with a ventral teeth ( Fig. 74 View FIGURES 72 – 81 ). Dorsal labiate plate with small sclerite caudal to sclerotized rings ( Fig. 86 View FIGURES 82 – 93 ). Posterior wall with rounded interramal lobes ( Fig. 98 View FIGURES 94 – 105 ). Dorsal structure covering half of interramal lobes, medial process absent ( Fig.98 View FIGURES 94 – 105 ).
Geographic distribution. Northeastern Africa ( Sudan), Eastern Africa ( Madagascar and Tanzania), Southern Africa ( South Africa) and the Seychelles Islands in the Indian Ocean (Schuh 2002–2014) ( Fig. 107 View FIGURE 107 ).
Plant associations. Unknown.
Discussion. Collaria improvisa is easily distinguished from C. obscuricornis and C. schwartzi sp. nov. by the transverse V-shaped pale stripe on head, pale-yellow collar, brownish spots on hemelytra, and by male and female genitalia. Reuter (1893), described C. improvisa from specimens of Seychelles Islands without designating a holotype; he deposited the studied specimens in the Muséum National d'Histoire Naturelle (MNHN). We did not find Reuter´s type material or syntype series at MNHN, Naturhistoriska riksmuseet (NHRS), Finnish Museum of Natural History (MZH), or in other museums. Nevertheless, we found one specimen at the NHRS, bearing an identification label in Poppius handwriting, who worked with material corresponding to the description by Reuter.
We examined specimens from South Africa, but the species is also recorded from Northern and Estern Africa, thus indicating that further collecting is needed not only to expand the known range for this species, but also to known its plant associations.
Examined material.
