( Figs. 39 , 77 ) Type locality. Peru , Cusco . Description. Holotype female. Dorsal coloration. Head black with the area near eyes and behind each ocelli dark castaneous orange; antennal segments I–III black, IV bicolorous, yellow with posterior third black; pronotum black with anterolateral and posterolateral margins, humeral angles and slender longitudinal stripe running across midline from inner margin of callus to mid third of posterior border red; scutellum, clavus and corium black; hemelytral membrane dark brown; connexival segments III–IX and dorsal abdominal segments III–IX shiny red. Ventral coloration. Head black with the area near eyes dark castaneous orange; buccula black; rostral segments I–IV reddish brown; pro-, meso- and metasternum reddish brown; propleuron reddish brown with upper margin and two discoidal spots reddish brown, one on the acetabulae, the second near middle third of posterior margin; meso- and metapleuron reddish brown with red discoidal spot on acetabulae; abdominal sterna III–VII reddish brown with dark yellow discoidal spot on each side of midline; pleural abdominal margins III–VII shiny red; gonocoxae I shiny red with outer margin black; laterotergites VIII–IX shiny red. Structure. Head. Antennal segment III uniformly elongate, slender; rostrum reaching anterior border of metasternum. Thorax. Pronotum. Trapeziform; anterolateral margins crenulate; posterolateral margins conspicuously crenulate, each projection broad; posterior border straight; humeral angles conspicuously expanded with the spine apically obtuse. Measurements. Female. Body length 19.46; head length 1.98; head width across eyes 2.60; interocular distance 1.17; interocellar distance 0.49; preocular distance 1.14; length antennal segments I 3.78, II 2.91, III 2.35, IV 6.75; length rostral segments I 1.55, II 1.86, III 1.45, IV 0.93; pronotum total length 4.03; maximum width across humeral angles 7.56; scutellum length 1.98, width 2.41. Male. Unknown. Type material. HOLOTYPE male: PERU : Cusco , Estación Biológica Villa Carmen , 522 m , 12.894554° S-71.39935 °W, i–2014 , E. Rodriguez ( UNAM ). Etymology. From the Latin “ genuinus ” meaning natural, native, authentic. Discussion. Differential diagnosis. Resembling L. peruviensis Brailovsky & Barrera (2006) ( Figs. 35 , 74 ), by having the antennal segment III slender, antennal segment IV bicolorous, clavus and corium entirely black to reddish brown, pro-, meso- and metapleuron black to reddish brown, and connexival segments III–IX and pleural abdominal margins III–VII entirely shiny red or yellowish orange. In L. geniunus sp. nov. , ( Figs. 39 , 77 ), the pro-, meso-, and metapleuron has a red discoidal spot above each acetabulae; the abdominal sterna III–VII reddish brown with dark yellow discoidal spot at each side of midline; pronotum black with anterolateral and posterolateral margins, humeral angles, and slender longitudinal stripe across midline reddish; and humeral angles exposed with the spine apically obtuse, while on L. peruviensis the pro-, meso- and metapleuron including the acetabulae are entirely black, abdominal sterna III–VII yellowish orange, pronotum entirely black and humeral angles rounded.
