description: <i>Filicicoris meyeri</i> sp. nov. Figs. 1, 2 A–C, E–I, K 3 G–J, 4 E, F, 5 C, D, 6 A, 7 A <i>Etymology</i> This species is named in honour of Dr Jean-Yves Meyer of the Délégation à la recherche de Polynésie français, who was instrumental in us undertaking research in Tahiti. He was most generous with his time and freely gave information that was critical to our research. <i>Material</i> <i>Holotype</i>.

Coloration (Fig. 1): Mainly black with hemelytra whitish yellow. Head. Mostly black; antennal segment I yellow to pale brown, segment II mostly dark brown to black, with basal one third yellow to pale brown, segments III–IV dark brown to black; labium mostly yellow with apex of segment IV dark brown to black. Eye brown to dark brown. Thorax: Pronotum and scutellum, thoracic pleura including scent gland evaporative area uniformly black. Hemelytron: Clavus uniformly black, corium mostly whitish yellow, translucent, with brownish area along inner margin of corium; embolium whitish yellow, brown anteriorly; cuneus uniformly whitish yellow; membrane and cell uniformly brown. Legs: Coxae brown to black, with whitish yellow apices; femora, tibia and tarsi mostly whitish yellow, tibiae often slightly darker than femora, tarsi sometimes with pale brown to brownish segment III. Abdomen: Uniformly dark brown to black. Surface and vestiture: As in generic description, with some dark setae on head and pronotum. Structure and measurements: As in generic description. Body ca. 3.0– 3.5 × as long as pronotum; head slightly elongate and acute dorsally (Fig. 2 A); vertex ca. 2.0– 2.4 × as wide as eye; antenna slightly shorter than body length; antennal segment I ca. 0.6–0.9 × as long as head width, 0.4–0.6 × longer than pronotum width; antennal segment II ca. 1.8 –2.0× longer than head width, ca. 1.2–1.4 × longer than pronotum width; segment III ca. 0.75 × longer than segment II; mesoscutum not exposed; pronotum ca. 1.5–1.8 × wider than long and ca. 1.5–1.6 × wider than head. Male genitalia (Fig. 3 G–J): Right paramere folded dorsally (Fig. 3 I); left paramere moderately swollen basally (Fig. 3 J); vesica with three lobes, two long lobes possessing small tubercles apically, short lobe placed dorsally, not bearing tubercles or small sclerotized spicules (Fig. 3 H). <i>Female.</i> Total length 3.5–3.7. Coloration (Fig. 1): Similar to male, but antennal segment II sometimes mostly pale brown, brown apically. 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. 1.9–2.6 × wider than eye diameter; antennal segment I ca. 0.7–0.8 × wider than head width, ca. 0.4–0.5 × longer than pronotum width; segment II ca. 1.6–1.9 × longer than head width, ca. 1.0– 1.2 × longer than pronotum width; pronotum ca. 1.6 × wider than long and ca. 1.5–1.6 × wider than head width. Female genitalia (Fig. 5 C, D): Anterior margin of dorsal labiate plate more or less sclerotized (Fig. 5 C); sclerotized rings on dorsal labiate plate ca. 0.2 × longer than dorsal labiate length (Fig. 5 C); distance between interramal lobes subequal to interramal lobe width. (Fig. 5 D). <i>Distribution</i> The species was collected from Taravao Plateau, Tahiti Is. (Fig. 6 A). <i>Host plants</i> Specimens were collected from fern <i>Nephrolepis hirsutula</i> (Nephrolepidaceae) (Fig. 7 A). This species was found on the underside of <i>Nephrolepis hirsutula</i> fronds, and both sexes and a nymph were collected, which supports this fern species being recognized as a breeding host. The fern was found in mostly a disturbed clearing beneath and near <i>Metrosideros</i>, from which <i>Coridromius taravao</i> Tatarnic and Cassis and <i>C. tahitiensis</i> Tatarnic and Cassis were collected (Tatarnic and Cassis 2013). <i>Discussion</i> The species cannot be confused with any other <i>Filicicoris</i> species due to its coloration and peculiar male genitalia.
