Head, tylus and antennal segments I–III black, IV missing; pronotum black with collar, anterolateral and posterolateral borders, humeral angles, and T-shaped yellowish orange mark near to midline of pronotal disk; scutellum yellow with basal angles black; clavus black with orange basal stripe at inner margin; basal angles of corium black, anterior half of costal margin and large discoidal spot close to middle third of apical margin orange; hemelytral membrane dark brown; connexival segments III and VII yellowish orange, IV–VI bicolorous, anterior third black and posterior third yellowish orange; dorsal abdominal segments III–VI and VIII–IX orange, VII black; intersegments between III–VI black. Ventral coloration. Head and rostral segments I–IV black; buccula black with upper margin yellow; pro-, meso- and metasternum black; propleuron black with upper margin and posterior margin orange; meso-, and metapleuron black; pro-, meso- and meta-acetabulae black with orange spot; coxae, trochanter, tibiae and tarsi black; femora black with posterior third orange and tip black; abdominal sterna black, midline symmetrically with a yellow transverse paired spot near posterior border of each sternite; pleural abdominal margins III and VII yellowish orange with small black spot near to the anterior angle, and IV–VI bicolorus, anterior half black and posterior half yellowish orange; gonocoxae I black; laterotergites VIII–IX yellowish orange. Structure. Head. Antennal segment III uniformly elongate, slender; rostrum reaching posterior margin of mesosternum. Thorax. Pronotum. Trapeziform; anterolateral and posterolateral margins almost smooth; posterior border straight; humeral angles subacute, not exposed.

Measurements. Female. Body length 20.34; head length 2.09; head width across eyes 2.85; interocular distance 1.27; interocellar distance 0.55; preocular distance 1.05; length antennal segments I 4.09, II 3.22, III 2.66, IV missing; length rostral segments I 1.61, II 1.55, III 1.30, IV 1.05; pronotum total length 4.34; maximum width across humeral angles 7.25; scutellum length 2.66, width 3.10.

Male. Unknown.

Type material. HOLOTYPE female: BRAZIL, Rio, 1149 (ZMHU).

Etymology. From the Latin “ factiosus ”, meaning powerful, eager for power.

Discussion. Differential diagnosis. Laminiceps infrequens here described and L. factiosus sp. nov., are the only known species with the scutellum almost entirely yellow (Figs. 21–22). In L. infrequens the apex of scutellum is black and basal angles yellow; corium without yellowish orange discoidal spot near middle third of apical margin; femora and acetabulae black; and pronotal disk with wide complete yellow transverse fascia absent in L. factiosus, on which the apex of scutelllum is yellow and basal angles black; corium with large orange discoidal spot near middle third of apical margin; femora clearly bicolorous; acetabulae with orange irregular spot; and pronotal disk with yellowish orange T-shaped mark near to midline.
