Antenna: Segment I widened medially (as in Namyatova et al., 2016: fig. 8B), ca. 1.1–1.2× as long as head width, ca. 0.9× as long as pronotum width; segment II 2.0–2.2× as long as head width, 1.3–1.4× as long as pronotum width; antennal segment III almost as long as segment II; segment IV slightly shorter than segment III. Thorax: Anterior part of pronotum shorter than posterior part; collar delimited; posterior part slightly upraised, posterior margin of pronotum slightly concave; pronotum ca. 1.2× as wide as long and 1.6× as wide as head; mesoscutum slightly exposed or not exposed. Hemelytron: Area along inner margin of corium swollen; inner margin of cuneus straight, outer margin of cuneus 2× longer than width at base. Abdomen: Genital capsule rotated 45° relative to other segments. Genitalia: Genital capsule (fig. 14L) ventral wall ca. 1.5× as long as dorsal wall, with posterior margin of ventral wall not curved dorsally, with small tooth-shaped outgrowth; right side of genital capsule curved, left side of genital capsule not widened; right paramere sockets angulate, left paramere socket rounded; distance between paramere sockets subequal to 1/4 of genital capsule base width. Right paramere (fig. 11AB) distinctly curved in apical half; apex concave posteriorly; medial part narrower than basal part, outer margin of medial part convex and inner margin concave, without swelling, without setae; outer angle absent; inner angle present, with straight outgrowth, bearing setae; basal part of right paramere ca. 0.3× as long as rest of paramere. Left paramere (fig. 11AC) Apical part not flattened, with tooth on posterior side apically and with outgrowth on dorsal surface; middle part with short and wide outgrowth bearing setae. Aedeagus (fig. 10G) vesica without spicules; distal half of ductus seminis sclerotized, secondary gonopore placed near phallotheca mouth in repose; ductus seminis hooked apically.

Female. Total length 4.9–5.9. COLOR- ATION (fig. 4): Head: Similar to male, but without red stripes and markings; labial segments II–IV often yellow, segment II sometimes brown ventrally; antennal segment I sometimes reddish brown apically. Thorax: Similar to male; collar often brown to dark brown; scutellum yellow to pale brown with brown stripe medially; mesoscutum yellow, brown basally or uniformly brown; thoracic pleura yellow to pale brown with dark brown metepimeron, sometimes with markings also dark brown. Hemelytron: Similar to male, but outer part of clavus sometimes brown, same color as inner part; embolium pale brown with brownish base and reddish apex. Legs: Similar to male, but marking in apical half of femur red or reddish brown and sometimes absent on middle femur; abdomen similar to male, sometimes uniformly whitish yellow. SURFACE AND VESTITURE: As in male. STRUCTURE AND MEASUREMENTS: Structure as in male, body ca. 3.8–4.0× as long as pronotum width; vertex ca. 1.1–1.5× as wide as eye diameter; antennal segment I ca. 1.2–1.3× as long as head width, ca. 0.8–1.0× as long as pronotum width; segment II ca. 1.9–2.2× as long as head width, ca. 1.1–1.2× as long as pronotum width; pronotum ca. 1.2–1.4× as wide as long and ca. 1.6– 1.9× as wide as head.

ETYMOLOGY: The species is named after Fedor V. Konstantinov (St. Petersburg State University, Russia), who helped us to get many specimens for this study.

DISTRIBUTION: Indonesia, Sulawesi Is. (fig. 18).

HOST PLANTS: Unknown.

DISCUSSION: Antennal segments, and the middle and hind legs are lost in the female; the female genitalia were not dissected. Felisacus fedori is similar to F. cristobalus in the marking along the inner margin of corium and anterior part, which is broad and not reaching R+M (fig. 4); in contrast, the latter species differs from F. fedori in the pronotum mostly brown to dark brown with pale brown stripe medially, the cuneus translucent, colorless with brown mar- gins, and the outgrowth on the inner part of right paramere abrupt (fig. 11T).
