Felisacus usingeri Woodward, 1954: 47 (original description).

DIAGNOSIS: Recognized by the following combination of characters: head and pronotum mostly yellow; antennal segment I yellow, brown apically; transverse depression delimiting occipital region present only dorsally; labium reaching middle of mesosternum; distance between eye and pronotum slightly longer than eye diameter.

DESCRIPTION: Male. Unknown. Female. Total length 3.7. COLORATION (fig. 7): Head: Mostly yellow. Labium: Uniformly yellow. Antenna: Seg- ment I yellow, brown apically, segment II uniformly brown. Eye brown. Thorax: Pronotum and scutellum yellow; thoracic pleura yellow; scent gland evaporative area whitish yellow. Hemelytron: Mostly translucent, colorless; clavus yellow; marking along inner margin of corium brown; embolium with yellow tinge and pale brown margins; cuneus with yellow tinge, its outer margin brown. Legs: Coxae whitish yellow; femora whitish yellow, yellow apically; tibae yellow. Abdomen: Whitish yellow. SURFACE AND VESTITURE: Head, pronotum, scutellum, clavus, and costal vein anteriorly with scarce setae subequal to or shorter than antennal segment II diameter; antennal segments I and II with suberect setae shorter than antennal segment II diameter; femora clothed with suberect setae slightly longer than antennal segment II diameter. STRUCTURE AND MEASURE- MENTS: Body ca. 4.7× as long as pronotum width. Head: Depression delimiting occipital region distinct only dorsally; distance between depression and pronotum almost as long as eye diameter; longitudinal sulcus on dorsal surface shorter than eye diameter; distance from eye to pronotum slightly longer than eye diameter, not swollen; vertex ca. 1.8× as wide as eye, flat. Labium (as in Namyatova et al., 2016: figs. 6D, 9C): Reaching middle of mesosternum; segment I and II combined subequal to segment III; segments I ca. 1.5× as long as wide; segment II twice as long as wide, elongate, dorsally; segment III distinctly shorter than ventral side of head; segment IV twice as long as segment III. Antenna: Segment I slightly widened, 1.3× as long as head width, 0.8× as long as pronotum width; segment II 2.0× as long as head width, 1.1× as long as pronotum width. Thorax: Anterior part of pronotum distinctly shorter than posterior part; collar distinct; posterior part of pronotum slightly raised; posterior margin of pronotum slightly concave; pronotum ca. 1.1× as wide as long and 1.7× as wide as head; mesoscutum slightly exposed. Hemelytron: Area along inner margin of corium almost flat; inner margin of cuneus convex (as in Namyatova et al., 2016: fig. 13F), medial margin ca. 3× as long as base. Female genitalia not examined.
