Dicyphylus scaevolae , new species

Figure 24, map 6, table 1, plates 6, 7

DIAGNOSIS: Recognized by generally pale green coloration, black antennal segment 1, black basal and apical bands on antennal segment 2, and dark, contrasting subapical bands on the hind femur; distinct fuscous markings at base of cuneus and apex of membrane cells (pl. 6); endosoma with a long, slender, basally directed, lateral spine arising adjacent to the secondary gonopore and with one long, erect apical spine subtended by two shorter laterally directed spines (fig. 24, pl. 7). Above mentioned aspects of coloration very similar to D. brachyscome , but that species with longer antennal segment 2 and less pronounced markings on corium at base of cuneus and on membrane. Apex of endosoma in D. scaevolae distinct from that of D. brachyscome , the latter with the apical spines in the form of an inverted horseshoe.

DESCRIPTION: MALE: Mean total length 2.72, mean pronotum width 0.78. COLORATION (pl. 6): Pale green; vertex medially and apex of clypeus infuscate; antennae largely black, segment 1 with a pale apical ring, segment 2 pale medially; labium infuscate apically; hind femur with a contrasting dark, broad, subapical band; tarsi black. SURFACE AND VES- TITURE (pl. 6): Dorsum smooth, weakly polished and weakly shining; dorsum clothed with short, black, reclining, simple setae. STRUCTURE: Head (pl. 6): As in generic description; antennal segment 2 long (0.90), 1.67 times width of head. Thorax (pl. 6): As in generic description. Hemelytron: As in generic description. GENITALIA (fig. 24, pl. 7): Pygophore: Conical with shallow indentation on posterior margin, ventrad of left paramere insertion. Endosoma: J-shaped, basal fusion of straps on left side; strap with obscure medial flange; long, slender, proximally directed lateral spine subtending secondary gonopore; four terminal spines, one long apical spine and three shorter lateral spines, one bifid, two straight; subapical membrane reduced; secondary gonopore subapical. Phallotheca: Posteroventral apical surface with dispersed field of denticles, dorsal edge of field with distinct spicules; shallow trough between spicules and posterodorsal edge; dorsal portion of posterior surface not serrate. Parameres: Left paramere with dorsoposterior margin relatively straight, slightly produced dorsad; posterior process gently deflected; anterior process short, base covered with broad field of spicules; prominent seta somewhat longer than other apical setae; right paramere with small anteriorly directed projection.

FEMALE (pl. 6): Differing from male as in generic description; mean total length 2.83, mean pronotum width 0.84.

ETYMOLOGY: Named for the goodeneaceous genus Scaevola , one of the known hosts of this taxon.

HOSTS: Recorded in large numbers from Goodenia ramelii (pl. 33C) and Scaevola ovalifolia (Goodeniaceae) . Recorded in small numbers on Brachyscome ciliaris ( Asteraceae ) and Solanum sp. ( Solanaceae ).

DISTRIBUTION (map 6): Recorded from the Goldfields region of Western Australia and the Alice Springs area of Central Australia.
