Diagnosis

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 View 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 View Fig. 1 ); vesica with four lobes, one of them with small tubercles apically, without small sclerotized spicules ( Fig. 3 View Fig. 3 D); dorsal labiate plate with membranous anterior margin and sclerotized rings ca. 0.15× longer than dorsal labiate plate length ( Fig. 5 View Fig. 5 E); interramal lobes placed close to each other, with distance between them 0.3× longer than interramal lobe width ( Fig. 5 View Fig. 5 F).

Description

Male. Total length 3.2–3.4. Coloration ( Fig. 1 View 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 View 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 View Fig. 3 D–F). Right paramere curved dorsally ( Fig. 3 View Fig. 3 E); left paramere moderately swollen basally ( Fig. 3 View Fig. 3 F); vesica with four lobes without small sclerotized spicules, one of the lobes bearing small scarce tubercles ( Fig. 3 View Fig. 3 D).

Female. 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 View Fig. 5 E, F). Anterior margin of dorsal labiate plate membranous ( Fig. 5 View Fig. 5 E), sclerotized rings on dorsal labiate plate ca. 0.15× longer than dorsal labiate plate length ( Fig. 5 View 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 View Fig. 5 F).

Distribution

The species was collected from two localities on Raiatea Island: Opoa and Uturoa ( Fig. 6 View Fig. 6 B).

Host plant

Unknown.

Discussion

Filicicoris raiatea can be confused with F. viridis in coloration ( Fig. 1 View Fig. 1 ) and the number of vesical lobes ( Fig. 4 View Fig. 4 A, B). F. viridis differs in the short head, which is rounded anteriorly ( Fig. 2 View 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 View Fig. 5 I), and the distance between the interramal lobes on the posterior wall subequals to the interramal lobe width ( Fig. 5 View Fig. 5 J). Filicicoris raiatea is also similar to F. rubramaculus 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 View Fig. 1 ) and the distance between interramal lobes being subequal to the interramal lobe width ( Fig. 5 View Fig. 5 H). Filicicoris raiatea is not separable from F. huahine in the coloration ( Fig. 1 View Fig. 1 ) and those two species also have similar female genitalia (compare Figs. 5 View Fig. 5 A, B and 5E, F), however, the vesica of F. huahine has six lobes, and one of them bears dense small sclerotized spicules ( Fig. 3 View Fig. 3 A).
