Felisacus rubricuneus Carvalho, 1956: 30 (original description).

DIAGNOSIS: Recognized by the following combination of characters: mostly dark coloration; antennal segment I brown to black, antennal segment II yellow, head reddish brown; pronotum brown to black laterally with reddish brown stripe medially; marking along inner margin of corium brown, wide, not extending toward R+M anteriorly; cuneus red, cylindrical antennal segment I (as in Namyatova et al., 2016: fig. 8A), vertex upraised (as in Namyatova et al., 2016: fig. 6D); body length in male 3.6–3.8, inner part of cuneus brownish red; medial part of right paramere as wide as basal part, shorter than basal and apical parts combined, its inner margin widened ( Carvalho, 1956: fig. 17a), vesica with five spicules, none of which can be homologized with the spicules of other species, one of spicules large and suboval (fig. 9H).

DESCRIPTION: Male. Total length 3.6–3.8. COLORATION (fig. 6): Head: Yellow to pale brown with reddish tinge dorsally and ventrally, yellow anteriorly and brown to reddish brown laterally. Eye dark brown to black sometimes with reddish tinge. Labium: Uniformly yellow or with segment IV pale brown. Antenna: Segment I brown with reddish tinge; segment II yellow, segment III yellow basally gradually darkening apically. Thorax: Pronotum mostly brown, yellow to pale brown medially; scutellum pale brown; pleura including scent gland evaporative area whitish yellow. Hemelytron: Mostly translucent, colorless; clavus and marking along inner margin of corium posteriorly brown; cuneus dark red; membrane with yellow or grayish tinge, cell yellow with reddish tinge. Legs: Mostly yellow, hind tibia and tarsi dark yellow to pale brown. Abdomen: Yellow. SURFACE AND VES-

TITURE: Dorsum and antennal segments I and II, with scarce setae mostly shorter than antennal segment II diameter; femora covered with setae longer than antennal segment II diameter. STRUCTURE AND MEASUREMENTS: Body ca. 4.3–4.5× as long as pronotum width. Head: Depression delimiting occipital region present dorsally and laterally (as in Namyatova et al., 2016: fig. 4E); distance between depression and pronotum shorter than eye diameter; longitudinal sulcus on dorsal surface longer than eye diameter; distance from eye to pronotum longer than eye diameter, slightly swollen laterally (as in Namyatova et al., 2016: fig. 4E); vertex 2.0– 2.2× as wide as eye, upraised. Labium (as in Namyatova et al., 2016: figs. 6D, 9C): Reaching middle posterior margin of mesosternum; segments I and II combined longer than half of segment III; segment I shorter than wide; segment II slightly longer than wide, elongate dorsally; segment III slightly shorter than ventral side of head; segment IV more than 2.5–3× as long as segment III. Antenna: Segment I distinctly longer than head width, cylindrical, ca. 1.5× as long as head width, ca. 0.9× as long as pronotum width; segment II ca. 2.0–2.1 as long as head width, ca. 1.2–1.3× as long as pronotum width. Thorax: Anterior part of pronotum slightly shorter than posterior part; collar delimited; posterior part slightly upraised; posterior margin of pronotum slightly concave; pronotum ca. 1.1–1.2× as wide as long and 1.6–1.7× as wide as head. Hemelytron: Area along inner margin of corium almost flat; inner margin of corium convex (as in Namyatova et al., 2016: fig. 13E), ca. 3× as long as base. Abdomen: Genital capsule rotated left at right angle relative to rest of abdomen. Genitalia: Left paramere (fig. 13K) L-shaped, apical part flattened, with toothlike outgrowth on posterior side medially (as in fig. 11G) and without outgrowth on dorsal surface; middle part widened, without swelling or outgrowth; setae only on middle part near outer margin. Aedeagus (general view as in Namyatova et al., 2016: fig. 22I) conjunctiva weakly sclerotized, sclerotized part of ductus seminis very short, secondary gonopore placed at base of vesica in repose; vesica with five spicules, none of which can be homologized with the spicules of other species (fig. 9H).

DISTRIBUTION: Caroline Is. (Kusaie) (fig. 20).

HOST PLANTS: Unknown.

DISCUSSION: Females were not examined. Due to its coloration F. rubricuneus cannot be confused with any other Felisacus species. Superficially it is similar to other dark-colored species with a red cuneus, such as F. bau , F. bellus , F. malayensis , F. senaru , and F. signis . However, all those species differ in the posterior part of pronotum being mostly yellow to pale brown and the antennal segment II has similar coloration or darker than antennal segment I.
