description: <i>Filicicoris raiatea</i> sp. nov. Figs. 1, 3 D–F, 5 E, F, 6 B <i>Etymology</i> The species is named after the Raiatea Island, where it was collected. <i>Material</i> <i>Holotype</i>. French Polynesia: Society Islands: Raiatea Island: Opoa, 151.37238 °W, Mar 1955, N. L. H. Krauss, 1 &amp;male; (00045858) (BPBM). 16.8397 °S <i>Paratypes</i>. French Polynesia: Society Islands: Raiatea Island: Opoa, 16.8397 °S 151.37238 °W, Mar 1955, N. L. H. Krauss, 8 &amp;male; (00045856, 0 0 0 45860, 0 0 0 46047, 00045918–00045922), 11 &amp;female; (00045929–00045933, 0 0 0 45865, 0 0 0 45864, 0 0 0 45855, 0 0 0 45863, 0 0 0 45854, 00045928) (BPBM). Uturoa, 1–100 m, 16.73041 <b>°</b> S 151.44299 <b>°</b> W, Aug 1969, N. L. H. Krauss, 6 &amp;male; (00045914–00045917, 0 0 0 45857, 00045859), 1;u (00045923), 6 &amp;female; (00045924–00045927, 0 0 0 45861, 00045862) (BPBM). <i>Diagnosis</i> Recognized by the following combination of characters: body short, total length 3.2–3.4 in male and 3.6–3.9 in female; mostly yellow coloration; head in dorsal view elongate and slightly acute apically (as in Fig. 2 A); antennal segment I ca. ca. 0.9 –1.0× in male and ca. 0.7–0.9 × in female longer than head width (Fig. 1); vesica with four lobes, one of them with small tubercles apically, without small sclerotized spicules (Fig. 3 D); dorsal labiate plate with membranous anterior margin and sclerotized rings ca. 0.15 × longer than dorsal labiate plate length (Fig. 5 E); interramal lobes placed close to each other, with distance between them 0.3 × longer than interramal lobe width (Fig. 5 F). <i>Description</i> <i>Male.</i> Total length 3.2–3.4. Coloration (Fig. 1). 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. As in generic description, without dark setae on head and pronotum. Structure and measurements. Body 3.2–3.4 × longer than pronotum; head slightly elongated and acute dorsally (as in Fig. 2 A); vertex ca. 1.6–1.9 × wider than eye; antenna slightly longer than body length; antennal segment I ca. 0.9 –1.0× as long as head width and ca. 0.6–0.7 × longer than pronotum width; antennal segment II 2.3–2.5 × longer than head width, ca. 1.7–1.8 × longer than pronotum width; antennal segment III ca. 0.5–0.75 × as short as segment II; mesoscutum not exposed or slightly exposed; pronotum ca. 1.6–1.8 × wider than long and ca. 1.4 × wider than head. Male genitalia. (Figs. 3 D–F). Right paramere curved dorsally (Fig. 3 E); left paramere moderately swollen basally (Fig. 3 F); vesica with four lobes without small sclerotized spicules, one of the lobes bearing small scarce tubercles (Fig. 3 D). <i>Female.</i> Total length 3.6–3.9. Coloration. As in male. Surface and vestiture. As in male. Structure and measurements. Structure as in male; body ca. 3.2–3.3 × longer than pronotum width; vertex ca. 1.4–1.8 × wider than eye; antennal segment I ca. 0.7–0.9 × longer than head width and ca. 0.4–0.6 × longer than pronotum width; segment II ca. 1.9–2.1 × longer than head width, ca. 1.3–1.4 × longer than pronotum width; pronotum ca. 1.8 –2.0× wider than long and ca. 1.5–1.6 × wider than head. Female genitalia (Figs. 5 E, F). Anterior margin of dorsal labiate plate membranous (Fig. 5 E), sclerotized rings on dorsal labiate plate ca. 0.15 × longer than dorsal labiate plate length (Fig. 5 E); interramal lobes on dorsal labiate plate placed close to each other, distance between them 0.3 × longer than interramal lobe (Fig. 5 F). <i>Distribution</i> The species was collected from two localities on Raiatea Island: Opoa and Uturoa (Fig. 6 B). <i>Host plant</i> Unknown. <i>Discussion</i> <i>Filicicoris raiatea</i> can be confused with <i>F</i>. <i>viridis</i> in coloration (Fig. 1) and the number of vesical lobes (Fig. 4 A, B). <i>F. viridis</i> differs in the short head, which is rounded anteriorly (Fig. 2 D); antennal segment I is longer than the head width, the dorsal labiate plate has the large sclerotized rings, ca. 0.3 × longer than the dorsal labiate plate (Fig. 5 I), and the distance between the interramal lobes on the posterior wall subequals to the interramal lobe width (Fig. 5 J). <i>Filicicoris raiatea</i> is also similar to <i>F. rubramaculus</i> in the vesical spicules, but can be separated by the head and the markings on posterior margin of clavus and the inner part of corium being red (Fig. 1) and the distance between interramal lobes being subequal to the interramal lobe width (Fig. 5 H). <i>Filicicoris raiatea</i> is not separable from <i>F. huahine</i> in the coloration (Fig. 1) and those two species also have similar female genitalia (compare Figs. 5 A, B and 5 E, F), however, the vesica of <i>F. huahine</i> has six lobes, and one of them bears dense small sclerotized spicules (Fig. 3 A).
