Felisacus minutus Carvalho, 1981: 6 (original description).

DIAGNOSIS: Recognized by the following combination of characters: short body, 2.6 mm in male; posterior margin of pronotum brown with yellow wide stripe medially; cuneus red, with yellow outer part and brown margins; marking along inner margin of corium pale brown, not reaching R+M anteriorly antennal segment I cylindrical (as in Namyatova et al., 2016: fig. 8A); transverse depression on head extending laterally, vertex upraised (as in Namyatova et al., 2016: fig. 6D); vertex ca. 1.3× as wide as eye diameter; cuneus 3× as wide as base; medial part of right paramere distinctly wider than basal part, its outer and inner parts straight (fig. 12AC); vesica with six spicules, including spicule A.

REDESCRIPTION: Male. Total length 2.6. COL- ORATION (fig. 6): Head: Pale brown with reddish tinge. Eye brown, reddish laterally. Labium: Yellow. Antenna: Segment I pale brown with reddish tinge, whitish yellow basally; segment II reddish brown. Thorax: Anterior part of pronotum yellow with reddish tinge and brown anterior margin; posterior part of pronotum brown with wide yellow stripe medially; mesoscutum and scutellum yellow; thoracic pleura yellow; scent gland evaporative area yellow with reddish tinge apically. Hemelytron: Mostly translucent; inner part of clavus opaque, yellow with reddish tinge and with red margins; corium colorless; marking along inner margin of corium pale brown; cuneus red, with yellow outer part and brown margins; membrane and membrane cell with grayish tinge. Legs: Mostly yellow with red markings in femora and tibiae; tarsal segments II–III pale brown. SURFACE AND VESTITURE: Corium with shallow scarce punctures. Setae on body shorter or as long as antennal segment II diameter. STRUCTURE AND MEASURE- MENTS: Body ca. 4.3× as long as pronotum width. Head: Depression delimiting occipital region distinct 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 subequal to eye diameter, not swollen laterally (as in Namyatova et al., 2016: fig. 4E); vertex ca. 1.3× 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 length shorter than half of segment III; segment I shorter than wide; segment II slightly longer than wide, its dorsal surface elongate posteriorly; segment III subequal to ventral side of head. Antenna: Segment I cylindrical (as in Namyatova et al., 2016: fig. 8A), ca. 1.6× as long as head width, ca. 1.1× as long as pronotum width; segment II ca. 2.0× as long as head width, ca. 1.4× 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 concave; pronotum ca. 1.2× as wide as long and ca. 1.4× as wide as head; mesoscutum exposed. Hemelytron: Area along inner margin of corium flat; inner margin of cuneus convex (as in Namyatova et al., 2016: fig. 13E), outer margin of cuneus ca. 3× as long as base. Genitalia: Right paramere (fig. 12AC) distinctly curved in apical part; apex straight dorsally; medial part distinctly wider than basal part, bearing setae, with margins almost straight; outer angle distinct, inner angle rounded, without setae; basal part of paramere ca. 0.3× as long as rest of paramere. Left paramere (fig. 12AD) L-shaped; apical part not flattened, with tooth on posterior side medially (as in fig. 34G) 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 and Cassis, in press: fig. 22I) conjunctiva weakly sclerotized, sclerite around secondary gonopore short, bowl shaped, secondary gonopore placed at base of vesica in repose; vesica with six spicules, including long spicule A and five additional spicules of different shape and size (fig. 9D).

Female. Not seen.

DISTRIBUTION: Papua New Guinea (fig. 20).

HOST PLANTS: Unknown.

DISCUSSION: Carvalho (1981) described F. minutus from two males. We examined the holotype and an additional male specimen of the species. This species is unlike its congeners on the basis of coloration of the pronotum, size of the vesical spicules.

MATERIAL EXAMINED: Holotype: PAPUA NEW GUINEA: Manus: Bismarck Arch., Momote, 2.06168 ° S 147.4245 ° E, 24 Dec 1959, T.C. Maa, 13 ( BPBM _TCN 00002956) ( BPBM).
