Type Species: Dampierella schwartzi sp. nov., by original designation

Holotype: AUSTRALIA: Western Australia: 27.6 km N of Coral Bay Rd on Cardabia–Ningaloo Rd, 22.90198°S 113.8167°E, 25 m, 29 Oct 2004, Cassis, Wall, Weirauch, Tatarnic, Symonds, Dampiera incana var. incana R.Br. (Goodeniaceae), det. PERTH staff PERTH 6989314, 13 (AMNH _ PBI 00030304) (WAMP). Diagnosis: Similar to Halticus but readily distinguished by the following combination of characters: gena height less than eye height; male with well-developed endosoma and single spinelike spicule; both sexes Description: Macropterous, body length 2.27–2.6 mm (Table 1). Coloration (Fig. 1): Dark brown and black with yellow or yellow-brown markings. Surface and Vestiture (Figs. 1, 2): Head mostly smooth and impunctate; pronotum punctate; thorax, hemelytra and abdomen impunctate; head with a few hairlike setae, antennae with closely adpressed hairlike setae, segment I with a few thin spinelike setae, body clothed in white, adpressed scalelike setae and adpressed to semi-erect yellow-brown hairlike setae, legs with decumbent hairlike setae, metafemora with a few spinelike setae, metatibia spinose; both parameres with spinelike setae.

Structure (Figs. 1–3): Body elongate and slightly ovate. Head (Figs. 1, 2 A–D): Transverse, short, wider than tall; eyes large and substylate, touching pronotum; height of gena subequal to height of eye; posterior margin of vertex raised as a thin carina, head wraps around pronotum; clypeus not projecting forward beyond frons; buccula small, narrow. Antennae (Figs. 1, 2 A–D): Insertion in line with lower margin of eye; shorter than body length, segment I shorter than height of eye, somewhat swollen, segment III longer than IV. Labium (Fig. 2 C–D): Extending just beyond metacoxae, segment I slightly longer than gena height. Thorax (Figs. 1, 2 A, C–F): Pronotum trapezoidal, shallowly inclined, collar thin, obscured by head, callosite region obsolete, humeral angles rounded, post-humeral angles depressed, posterior margin medially concave and deflected; mesoscutum obscured by pronotum, rarely visible as a thin strip; metathoracic spiracle a narrow slit, without evaporative bodies; metathoracic scent gland external efferent system small, peritreme broad and rounded, located directly above ostiole. Hemelytra (Figs. 1, 2 A, C): Costal margin gently convex, weakly laterally declivent; cuneus broad; membrane with single cell, extends beyond abdomen, not deflected downwards at cuneal fracture. Legs (Figs. 1, 2 C): All femora moderately swollen; metatibia elongate; pretarsi with lamellate, apically convergent parempodia and fleshy pulvilli. Abdomen (Fig. 2 C): Elongate-ovoid. Male genitalia (Figs. 2 G–I, 3A–C): Pygophore short, without modifications or processes; both parameres projecting from pygophore, right paramere longer than left; left paramere with large, broad, projecting sensory lobe, arm apically bifid; right paramere basally thicker than left, with apical club deflected laterally; phallotheca with apex laterally compressed, dorsally keeled; ductus seminis short with flexible ribbing, section prior to secondary gonopore lacking ribbing; secondary gonopore scoop-shaped, opening ventrally, with faint scalelike texturing; endosoma with single, curved, spinelike spicule. Female genitalia (Figs. 3 D–F): sclerotized rings thin, weakly sclerotized, subcontiguous, elongate-elliptical, with lateral margins and adjacent portion of dorsal labiate plate moderately upturned; margin of ventral labiate plate adjoining rami forming a very weakly sclerotized band; posterior wall medially divided, laterally with paired, apically converging sclerotized bands, medially weakly sclerotized and swollen, bearing fields of spines, posterior of each lateral plate a moderately sclerotized, declivent, concave triangulate plate; vestibulum with bilaterally symmetrical sclerotization.

Distribution: Dampierella is a monotypic genus; all specimens were collected from two localities in northwest Western Australia (Fig. 4).

Etymology: This genus is named for its host affiliation with the plant genus Dampiera .
