Dicyphylus beaglensis , new species

Figure 20, map 6, table 1, plates 6, 7

DIAGNOSIS: Recognized by emerald green pronotum and scutellum, fumose hemelytron and femora, and the fumose to pale antennal segment 1; hemelytral surface appearing more strongly crenulate than in other known species (pl. 6); endosoma with a short serrate prominence subtending the secondary gonopore, a long, basally directed spine adjacent to gonopore, and apex with a short and a long spine, the latter with jagged foliaceous margins (fig. 20, pl. 7). Similar to D. solani in having antennal segment 1 pale or weakly infuscate rather than black and in the form of elongate apical endosomal spines with foliaceous margins. Distinguished from D. solani by gray coloration of body and contrasting black distal third of antennal segment 2 in that species.

DESCRIPTION: MALE: Total length 2.65, pronotum width 0.71. COLORATION (pl. 6): Head partially, pronotum mostly, and scutellum emerald green; clypeus unicolorous pale; antennal segment 1 pale, segment 2 unicolorous, weakly to moderately infuscate; hemelytron and appendages fumose; tarsi infuscate, dark, contrasting with remainder of leg. SUR- FACE AND VESTITURE (pl. 6): Dorsum weakly polished, surface appearing weakly crenulate; dorsal vestiture of short, recumbent, black setae. STRUCTURE: Head (pl. 6): As in generic description; antennal segment 2 relatively long (0.96), 1.78 times width of head. Thorax (pl. 6): As in generic description. Hemelytron: As in generic description. GENITALIA (fig. 20, pl. 7): Pygophore: Conical with shallow indentation on posterior margin, ventrad of left paramere insertion. Endosoma: Sigmoid, basal fusion of straps on left side; strap with short serrate prominence medially; long, slender, proximally directed spine subtending secondary gonopore, and two apical spines one short and smooth, other about twice as long and with extensive marginal serration; midpoint of strap with flattened, slightly expanded and marginally serrate spine; secondary gonopore situated just distad of midpoint of endosoma. Phallotheca: Apical posteroventral surface with small field of denticles and short transverse row of spicules; posterodorsal edge serrate, curving ventrad on anterior surface. Parameres: Left paramere with dorsoposterior margin approximately straight, barely elevated dorsad; posterior process gently deflected; anterior process short, surmounting broad base; prominent seta apparently absent; right paramere with small or indistinguishable anteroapical projection.

FEMALE (pl. 6): Coloration as in male; structure as in generic description; mean total length 2.68, mean pronotum width 0.76.

ETYMOLOGY: Named for its occurrence near Beagle Hill, Western Australia.

HOST: Recorded from Dicladanthera forrestii (Acanthaceae) .

DISTRIBUTION (map 6): Known from the west coast of Western Australia, north of Carnarvon.
