Krauss, 1 &amp;male; (00045882) (BPBM). <i>Diagnosis</i> Recognized by the following combination of characters: coloration uniformly yellow (Fig. 1); total length 3.2–3.4 in males and 3.6–3.8 in females; head from dorsal view elongate and slightly acute apically (as in Fig. 2 A); antennal segment I ca. 0.9 –1.0× in male and ca. 0.7–0.8 × in female longer than head width (Fig. 1); vesica with six membranous lobes, apex of one of them covered with dense small sclerotized spicules and apex of another lobe with small rare tubercles (Fig. 3 A), sclerotized rings on dorsal labiate plate small, ca. 0.1 × longer than dorsal labiate plate length (Fig. 5 A), and interramal lobes placed very closed to each other, at distance ca. 0.3 × longer than interramal lobe width (Fig. 5 B). <i>Description</i> <i>Male</i>. Total length 3.2–3.4. Coloration: Body mostly yellow; antennal segment III apically or entirely, antennal segment IV, labial segment IV and tarsal segment III pale brown to brown; eye yellow to pale brown; scent gland evaporative area whitish yellow. Surface and vestiture: Mostly as in generic description, without dark setae on head and pronotum. Structure and measurements: Body 3.2–3.4 × longer than pronotum; head elongate and acute dorsally (as in Fig. 2 A); vertex 1.9–2.1 × wider than eye diameter; antenna slightly longer than body length; antennal segment I ca. 0.9 –1.0× longer than head width and ca. 0.6–0.7 × longer than pronotum width; antennal segment II ca. 2.3–2.6 × longer than head width, ca. 1.6–1.8 × longer than pronotum width; antennal segment III ca. 1.5 –2.0× shorter than segment II; mesoscutum weakly to not exposed; pronotum ca. 1.7–1.8 × wider than long and ca. 1.3–1.5 × wider than head. Male genitalia (Fig. 3 A–C): Right paramere folded dorsally (Fig. 3 B); left paramere distinctly swollen basally (Fig. 3 C); vesica with six lobes, one of them with distinct short dense acute spicules and another lobe with scarce tubercles apically (Fig. 3 A). <i>Female.</i> Total length 3.6–3.8. Coloration: As in male. Surface and vestiture: As in male. Structure and measurements: Structure as in male; body ca. 3.2–3.4 × longer than pronotum width; vertex ca. 1.6–2.2 × wider than eye diameter; antennal segment I ca. 0.7–0.8 × longer than head width and ca. 0.5 × as long as pronotum width; segment II ca. 2.0– 2.4 × longer than head width, ca. 1.4–1.6 × longer than pronotum width; pronotum ca. 1.7–1.9 × wider than long and ca. 1.5 × wider than head. Female genitalia (Fig. 5 A, B): Anterior margin of dorsal labiate plate membranous (Fig. 5 A), sclerotized rings on dorsal labiate plate ca. 0.1 × longer than dorsal labiate plate length (Fig. 5 A); interramal lobes on dorsal labiate plate placed close to each other, each of them 3 × as long as distance between them (Fig. 5 B). <i>Distribution</i> Species was collected in Raiatea Island from two localities, Fare and Fitii (Fig. 6 A). <i>Host plant</i> Unknown. <i>Discussion</i> <i>F. huahine</i> might be confused with the pale specimens of <i>F. viridis</i> in the yellow coloration. However, <i>F. viridis</i> can be separated in having the larger body size, 4.3 –5.0 in males and females, its head is short and broadly rounded in dorsal view (Fig. 2 D); antennal segment I is longer than the head width (Fig. 1), its vesica has four lobes, one of them with scarce tubercles apically (Fig. 4 A, B). The dorsal labiate plate of <i>F. viridis</i> differs from that of <i>F. huahine</i> in having the large sclerotized rings (Fig. 5 I), and the distance between interramal lobes on posterior wall subequal to the interramal lobe width (Fig. 5 J). <i>Filicicoris huahine</i> and <i>F. raiatea</i> are very similar to each other in the coloration and body structures, and we could not find any characters to separate them externally (Fig. 1). They are also similar in female genitalia having small sclerotized rings, the anterior margin of dorsal labiate plate sclerotized and the interramal lobes placed close to each other (Fig. 5 B, F). However, the aedeagus of each species is distinct, with the vesica bearing a different number of membranous lobe, six in <i>F</i>. <i>huahine</i> and four in <i>F. raiatea</i> (Figs. 3 A, D), on this basis we treat them as separate species.
