Type material: HOLOTYPE ♂ labelled as follow: Macapá, Amapá, Brasil [= Brazil] / Quilombo Mel da Pedreira / área de savana [savanna environment] / 15.VI.2019 / leg. F.S. Carvalho-Filho / Armadilha luminosa [= light trap] (MPEG).
Measurements: Male Holotype. Total length: 1.04 mm; width between eyes: 0.19 mm; pronotum length: 0.21 mm; pronotum width: 0.49 mm; scutellum length: 0.14 mm; abdominal width: 0.54 mm.
Diagnosis. Recognized among species of Schizoptera (Cantharocoris) by the dark brown coloration and light brown wing membrane; sternum 6 with a broad and rounded posterior process (Figure 3C, black arrow); subgenital plate with a tiny process with bifid tip (Figure 3C, white arrow); right conjunctival appendage elongate and slender, with distal portion bearing tiny spine-like projections (Figure 3D), left conjunctival appendage short and plate-like (Figure 3D), right paramere very long and curved, with narrowed distal portion, left paramere with enlarged base and narrowed and a strongly curved distal portion (Figure 3D).
Description. Male (Figure 2): macropterous, body ovate. Coloration: generally dark brown, light brown membrane, Sc+C distinctly lighter than the remainder of hemelytra, legs yellow. Surface and vestiture: head, pronotum, and wing veins covered with long, light brown setae; several circular muscle scars on head; abdomen densely covered with elongate setae. Structure: Head: triangular in frontal view, synthlipsis about three times the width of the eye. Thorax: posterior pronotal margin weakly concave medially, scutellum triangular, with a rounded tip, hind coxa with well-developed adhesive pad, tarsal formula 3-3-3. Abdomen: Sternum 6 with a pigmented broad and rounded posterior process, sternum 7 with a pigmented broad and rounded process in the anterolateral corner of the left side, subgenital plate with a tiny process with bifid tip posteriorly directed (Figure 3C). Genitalia (Figure 3D): Right conjunctival appendage elongate and slender, with distal portion bearing tiny spine-like projections; left conjunctival appendage short and plate-like; right paramere very long and curved, with narrowed distal portion; left paramere with enlarged base and narrowed and strongly curved distal portion; vesica very long, looping, moderately slender, with 2–3 coils.
Etymology. Named after the savanna environment where the type-specimens were collected.
Distribution. Brazil (Amapá).
Remarks. The new species differs from all other described species of the subgenus Cantharocoris in having the following combination of features: sternum 6 with a pigmented broad and rounded posterior process, sternum 7 with a pigmented broad and rounded process in the anterolateral corner of left side, and subgenital plate with tiny process with bifid tip. Schizoptera (Cantharocoris) grandi Emsley, 1969 and Schizoptera (Cantharocoris) apatosulcata Emsley, 1969, both from Trinidad & Tobago, also have subgenital plate with the process with bifid tip, but it is anteriorly directed, while in the new species the process is posteriorly directed. However, the sterna 6 and 7 of these species lack the pigmented broad and rounded process.
