Morales, Ferreira & Forero ( Figs. 14 , 24 , 36 , 49 , 55 , 57, 58, 59, 60, 61 , 70 , 80 , 92 , 104 ) Diagnosis. Distinguished by the male antennal segment I four times the width of other segments ( Fig. 14 ); endosoma with medial left sclerite oval with microtrichia on surface ( Fig. 49 , 57 ) and ventral and dorsal right sclerites elliptical ( Fig. 55 , 58 ); posterior wall of female with rounded interramal lobes ( Fig. 104 ), dorsal structure small, and medial process shaped as an inverted Y ( Fig.104 ). Description. Male ( holotype ): COLORATION : Brown with black and pale yellow areas. Head: Dark brown; with a V-shaped transversal pale spot posterior to longitudinal sulcus and two spots behind eyes; eye brown; mandibular plate, maxillary plate and apex of buccula, black; labium yellowish with black apex; clypeus black; antennal segments: Scape yellowish, segment I black, segments II–IV brown. Thorax: Pronotum and collar brown, calli with dark brown lateral margins, inner region of calli reddish brown marbling and pale longitudinal line; two rounded black spots on humeral angles; lateral margins and humeral angles, pale; proepisternum black with pale margins; scutellum, with yellow-pale longitudinal line and pale apex. Hemelytra yellow to straw colored, with dark brown spot in regions of clavus (near to scutellum); internal region of corium extending from posterior half of claval suture to base of cuneus, dark brown; external region of embolium and median region of cuneus, brownish; hemelytral membrane dark brown; ostiolar peritreme margins yellow; legs pale yellow; pro- and meso coxae dark brown with pale spots; trochanter pale; posterior coxa dark brown to pale in apex, femur pale with rounded brown spots; tibia pale brown and tarsus brownish; median region of abdomen with a black spot; apex of pygophore, black. VESTITURE AND STRUCTURE : Head: Antenna densely pilose with interspersed short pilosity; length of long pilosity greater than width of segments, segment I strongly thickened (4 times width of segment II), remaining segments thin and cylindrical. Antennal segment I, 0.8 times width of head (Table 1); segment II 2.5 times longer than I (Table 1). Eyes, inner margin slightly sinuous and rounded in posterior margin. Buccula short and antennal sockets not reaching mandibular-maxillary plate suture. Labium smooth shiny with golden sparse semi erect short pilosity, reaching meta coxae; segment I thick, approximately twice width of segment II, reaching head base. Thorax: Pronotum with anterior lobe gradually narrowed and lateral margin carinated with long sparse and erect golden pilosity. Pronotal collar well delimited and separated from pronotum by smooth sulcus with shallow and sparse scores. Calli, convex and well delimited and separated reaching margin of pronotum; with granulations arranged in an internal bacillary forming irregular patches. Mesoscutum concealed by posterior margin of pronotum. Scutellum triangular plane with rough transversal lines and granulated. Proepisternum visible in dorsal view, rounded. Hemelytra smooth with short and sparse erect setae. MEASUREMENTS : See Table 1. GENITALIA: Pygophore: triangular ( Figs. 24 , 59 ), with a left projected lateroposterior margin ( Figs. 24 , 59 ). Parameres: Left paramere in medial view sickle-shape with dorsal margin of basal sensory lobe clearly convex and ventral margin of basal sensory lobe almost straight; hypophysis gradually acuminate to apex ( Figs. 36 , 60, 61 ), right paramere as in Fig. 61 . Endosoma: With medial left sclerite oval with microtrichia on surface ( Figs. 49 , 57 ); ribbon like sclerite with short lobe or area beneath secondary gonopore covered with trichia ( Figs. 49 , 57 ), ventral right sclerite elliptical with trichia on surface and dorsal right sclerite elliptical and with trichia on surface ( Fig. 55 , 58 ). Female: Similar to male in color and size, but slightly longer, antennal segment I two times width of segment II. MEASUREMENTS : Table 1. GENITALIA: First gonapophysis: With broad apical grooved region ( Fig. 70 ). Second gonapophysis: Apex triangular and with one teeth ( Fig. 80 ). Dorsal labiate plate with two small sclerites caudal to sclerotized rings ( Fig. 92 ). Posterior wall with rounded interramal lobes, and anterior angle narrow projected to blunt tip ( Fig. 104 ). Dorsal structure small and medial process shaped as an inverted Y ( Fig.104 ). Etymology. This species is named in honor of Michael D. Schwartz, for his productive taxonomic work on Miridae , especially with the subfamily Mirinae . Plant associations. Unknown. Geographic distribution. Ranging from Central Africa ( Democratic Republic of the Congo ) to Eastern Africa ( Tanzania and Malawi ) ( Fig. 107 ). Discussion. Collaria schwartzi sp. nov. can be easily distinguished from all known Collaria species by the endosoma with oval medial left sclerite, elliptical ventral and dorsal right sclerites, and the width of segment antennal I in male. This species resembles C. improvisa with regard to the male genitalia. Collaria schwartzi sp. nov. has a tubercle on the left lateroposterior margin of the pygophore with a prolongation similar to that of C. improvisa . The ventral and dorsal right sclerites of the endosoma are small, with a trichiate surface (smooth in C. improvisa ). Parameres are similar in all species of the genus ( Carvalho & Fontes 1981 ), except C. improvisa , C. obscuricornis and C. villiersi , which have the apical curvature strongly angled in relation to the body of the paramere. The right paramere in C. schwartzi has a broadly rounded protrusion on sensory lobe as in other species of genus ( Carvalho & Fontes 1981; Morales et al In prep. ). The most similar species to C. schwartzi is C. improvisa , but its known records are nearer to C. obscuricornis throughout most of its range (see Fig. 107 ). Collaria improvisa is distributed in South Africa and C. obscuricornis in South and East Africa ( Linnavuori 1974 ). We increase one new species to the genus Collaria , based on the examination of very few specimens collected from a limited number of localities. The non-continuous distribution found in this Afrotropical species is probably due to poor specimen collection in this region. Tatarnic & Cassis (2008) found similar results, in their work with Coridromius , where they argue that there are many more species to be discovered in Africa. Examined material.
