Felisacus adamsi Carvalho, 1956: 26 (original

description).

DIAGNOSIS: Recognized by the following combination of characters: dorsum mostly whitish yellow to yellow with reddish markings (fig. 4); antennal segment I cylindrical (as in Namyatova et al., 2016: fig. 8A), dorsal surface of labial segment II elongate posteriorly (Namyatova et al., 2016: fig. 6D); apical part of right paramere widened; middle part of right paramere less than twice as wide as basal part ( Carvalho, 1956: fig. 17c).

DESCRIPTION: Male. See Carvalho (1956) for the original description. Female. Total length 2.9–3.1. COLORATION (fig. 4): Head: Whitish yellow to yellow, with reddish tinge and markings. Eye brown to dark brown, often with reddish margins. Labium: Yellow. Antenna: Segment I mostly red with yellow base, segments II reddish brown, segments III–IV brown to dark brown. Pronotum. Yellow with pale brown anterior margin, anterior part with longitudinal red stripe laterally; mesoscutum yellow; scutellum yellow. Thoracic pleura. Yellow; scent gland evaporative area whitish yel- low. Hemelytron: Mostly colorless and translucent; inner part of clavus mostly opaque, with reddish margins; marking along inner margin of corium faint, whitish yellow; embolium and cuneus with reddish margins, embolium yellow apically; membrane with whitish-yellow cell. Legs: Yellow with reddish markings and pale pretarsus. Abdomen: Mostly yellow, genital segments with reddish marking. SURFACE AND VESTITURE: Dorsum and femora clothed with simple setae shorter than antennal segment II diameter; antennal segment I clothed with suberect setae subequal to or shorter than antennal segment II diameter; abdomen clothed with suberect setae of different length. STRUCTURE AND MEASUREMENTS: Body 3.9–4.0× 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 distinctly shorter than eye diameter; longitudinal sulcus on dorsal surface of head longer than eye diameter; distance from eye to pronotum as long as eye diameter, slightly swollen at sides (as in Namyatova et al., 2016: fig. 4E); vertex 2.2× as wide as eye; upraised (as in Namyatova et al., 2016: fig. 6D). Labium (as in Namyatova et al., 2016: figs. 6D, 9C): Segments I and II strongly reduced, combined less than half as long as segment III; segment I shorter than wide, segment II slightly longer than wide, its dorsal surface elongate posteriorly; segment III slightly shorter than head length ventrally. Antenna: Segment I cylindrical (as in Namyatova et al., 2016: fig. 8A), 1.6– 1.8× as long as head width, ca. 0.9× as long as pronotum width; segent II ca. 1.6–1.8× as long as width of head, ca. 1.0–1.1× as long as pronotum width; segment IV ca. 0.25× as long as segment III. Thorax: Anterior part of pronotum distinctly shorter than posterior part; collar delimited; posterior part slightly upraised posterior margin of pronotum straight; pronotum 1.2× as long and ca. 1.6× as wide as head; mesoscutum slightly exposed. Hemelytron: Area along inner margin of corium not swollen; inner margin of cuneus convex (as in Namyatova et al., 2016: fig. 13E), medial margin of cuneus ca. 3× as long as base. Genitalia (from Carvalho, 1956): Genital capsule and aedeagus not examined. Right paramere ( Carvalho, 1956: fig. 17c). Apical part distinct, broad, straight posteriorly; medial part less than twice as wide as basal part, bearing setae, with outer margin slightly concave and inner margin with distinct swelling; outer angle distinct, widened; inner angle rounded, without setae; basal part twice shorter than rest of paramere. Left paramere ( Carvalho, 1956: fig. 17d) paramere L-shaped; apical part not flattened, with toothlike outgrowth on posterior side medially and without outgrowth on dorsal surface; middle part widened, without swelling or outgrowth(s).

DISTRIBUTION: Micronesia, Ponape Is. (fig. 17).

HOST PLANTS: Unknown.

DISCUSSION: F. adamsi has similar external morphology to several other species, including F. auritulus , F. dauloi , F. filicicola , F. insularis , F. ochraceus , F. schuhi , and F. tanna . (figs. 4–7). We have not been able to examine the male genitalia of this species, because only paratype females were available for study from the NMNH. According to the illustrations given by Carvalho (1956), F. adamsi has a unique right paramere with a broad apical part ( Carvalho, 1956: fig. 17c).
