DIAGNOSIS: Recognized by the following combination of characters: relative dark coloration; head yellow to pale brown; posterior part of pronotum yellow to pale brown with wide brown stripe along posterior margin; antennal segment I mostly brown and segment II reddish brown; antennal segment I cylindrical (as in Namyatova et al., 2016: fig. 8A); vertex upraised (Namyatova et al., 2016: fig. 6D); body length in male 3.6–3.8, in female 3.8–4.1; medial part of right paramere slightly wider than basal part, with outer margin concave (fig. 13N), vesical with six spicules, including ling spicules A, B, and C, spicule C distinctly moved posteriorly (fig. 9I).

DESCRIPTION: Male. Total length 3.6–3.8. COLORATION (fig. 6): Head: Yellow to pale brown with reddish tinge dorsally. Eye dark brown to black. Labium: Yellow. Antenna: Segment I brown, pale yellow to yellow basally and ventrally; segment II reddish brown; segments III–IV dark brown to black, darker than segment II. Thorax: Pronotum yellow to pale brown, with brown anterior margin and wide brown stripe along posterior margin; mesoscutum pale brown, scutellum brown; thoracic pleura yellow; scent gland evaporative area whitish yellow. Hemelytron: Mostly colorless and translucent; inner part of clavus translucent or opaque, brown; marking along inner margin of corium brown; embolium with margins yellow; cuneus with pale brown margins and inner half red; membrane with greyish tinge. Legs: Coxae whitish yellow; femora, tibiae, and tarsi yellow. Abdomen: Yellow with greenish tinge. SURFACE AND VESTITURE: Corium smooth, impunctate. Dorsum clothed with setae suberect and longer than antennal segment II diameter; antennal segment I and femora clothed with suberect setae shorter than antennal segment II diameter; abdomen clothed with short erect setae. STRUCTURE AND MEASUREMENTS: Body ca. 4.4–4.7× 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 distinctly longer than eye diameter, not swollen laterally (as in Namyatova et al., 2016: fig. 4E); vertex ca. 1.5–1.9× as wide as eye; upraised view (Namyatova et al., 2016: fig. 6D). Labium (as in Namyatova et al., 2016: figs. 6D, 9C): Surpassing metasternum, but distinctly not reaching posterior margin of metasternum; segments I and II strongly reduced, combined shorter than half of segment III; segment I shorter than wide; segment II slightly longer than wide, its dorsal surface elongate posteriorly; segment III slightly shorter than ventral side of head; segment IV twice as long as segment III. Antenna: Segment I cylindrical (as in Namyatova et al., 2016: fig. 8A), ca. 1.7–1.9× as long as head width, ca. 1.1– 1.2× as long as pronotum width; segment II ca. 2.1–2.3× as long as head width, ca. 1.3–1.5× as long as pronotum width; segment III slightly longer than segment II; segment IV ca. 0.2× as long as antennal segment III. Thorax: Anterior part of pronotum shorter than posterior part; collar delimited; posterior part only slightly upraised; posterior margin of pronotum concave, pronotum ca. 1.2× as wide as long and ca. 1.6× as wide as head; mesoscutum slightly exposed. Hemelytron: Area along inner margin of corium flat; inner margin of cuneus concave (as in Namyatova et al., 2016: fig. 13E), outer margin of cuneus ca. 2.5× as long as base. Abdomen: Genital capsule rotated left at right angle relative to rest of abdomen. Genitalia: Right paramere (fig. 13N) apical part distinctly delimited, only slightly concave posteriorly, medial part slightly wider than basal part, bearing setae, with outer margin straight or slightly concave and inner margin slightly widened; outer angle distinct, not swollen; inner angle rounded, without setae; basal part ca. 0.2× as long as rest of paramere. Left paramere (fig. 13O) L-shaped; apical part not flattened, ca. 3× as long as wide, with tooth on posterior side medially and with- out outgrowth on dorsal surface; middle part widened, without swelling or outgrowth; setae present only on middle part near outer margin. Aedeagus (general view as in Namyatova et al., 2016: fig. 22I) conjunctiva weakly sclerotized; secondary gonopore placed at base of vesical in repose; sclerotization of ductus seminis around secondary gonopore shorter than wide; vesica with six spicules, including spicules A, B, and C, spicule C convolute basally and distinctly moved posteriorly (fig. 9I).

Female. Total length 3.8–4.1. COLORATION (fig. 6): Similar to male, sometimes dorsal side of head and pronotum with red or brown tinge, antennal segment I sometimes almost uniformly yellow to pale brown or yellow with reddish tinge; cuneus sometimes yellow with reddish brown margins and inner parts, tibiae sometimes brown. SUR- FACE AND VESTITURE: As in male. STRUCTURE AND MEASUREMENTS: Structure as in male; body ca. 4.4–4.5× as long as pronotum width; vertex ca. 1.8–2.5× as wide as eye; antennal segment I ca. 1.6–1.8× as long as head width, ca. 1.0× as long as pronotum width; segment II ca. 2.0–2.3× as long as head width, ca. 1.2–1.4× as long as pronotum width; pronotum ca. 1.2× as wide as long and ca. 1.6–1.7× as wide as head.

DISTRIBUTION: Specimens were collected only in Senaru (Lombok Is.) (fig. 20).

ETYMOLOGY: The species is named after the place Senaru (Lombok, Indonesia), where it was collected.

HOST PLANTS: Plesioneuron sp. (Thelypteridaceae) , many specimens.

DISCUSSION: Felisacus senaru can be confused with other dark specimens of this genus that possess a red or partially red cuneus, such as F. bau , F. bellus , F. jacobsoni , F. malayensis , and F. signis . These species differs from F. senaru in the cuneus entirely or mostly red and in the shape and/or number of vesical spicules (cf. fig. 9I with figs. 8D, E, M, 9A. K).
