Halophylus maireani , new species

Figure 48, map 11, table 1, plates 16, 17

DIAGNOSIS: Recognized by dirty greenish to brown coloration, the elongate and nearly parallel-sided body form, tibiae with dark spots at the bases of spines (pl. 16); apical endosomal spines of equal length, moderately elongate, slender, one bent near base, the other near apex (fig. 48, pl. 17). Female brachypterous with hemelytron just reaching apex of abdomen, coloration green rather than brown as in male (pl. 16). Most easily confused with H. tecticornii on the basis of frequently brown coloration, but tibial spines with dark bases in H. maireani and pale in H. tecticornii ; endosomal spines of unequal length in H. tecticornii (fig. 51, pl. 17). Females always green in H. maireani rather than brown as in H. tecticornii (pl. 16).

DESCRIPTION: MALE: Mean total length 3.29, mean pronotum width 1.02. COLORATION (pl. 16): Overall coloration mostly dark, chocolate brown, sometimes lighter; membrane heavily fumose; antennae and femora dark; femora with contrasting dark (obscure because of dark background coloration) spots, tibiae pale, spines with dark bases. SURFACE AND VESTITURE (pl. 16): Body surface smooth, weakly shining, with woolly sericeous setae and some reclining, dark common setae. STRUCTURE (pl. 16): Body form elongate-rectangular. Head: Head short and broad, eyes moderately bulging; eye occupying one-half height of head; antenna inserted just below ventral margin of eye, eye weakly emarginate above insertion; antennal segment 2 elongate, slen- der (1.18), 1.39 times width of head; labium reaching to about apex of metacoxa. Thorax: Pronotum weakly campanulate, with weakly concave sides, calli distinctly demarcated along posterior margin, posterior margin of pronotum straight; mesoscutum very narrowly exposed. Hemelytron: Costal margin nearly straight. GENITALIA (fig. 48, pl. 17): As in generic description but with the following details. Pygophore: Posteroventral surface with majority of setae consisting of stout dark spines. Endosoma: Dorsal apical spine gently curved ventrad, gradually attenuate to pointed apex; subapically ventral apical spine slightly bent laterad, apically parallel to and subequal in length to dorsal spine; secondary gonopore with fine denticles. Parameres: Left paramere with dorsoposterior surface somewhat elevated dorsad of posterior and anterior processes. Right paramere as in figure 48.

Female (pl. 16): Coloration usually much lighter than in male, greenish; strongly brachypterous, membrane abbreviated, just reaching apex of abdomen; mean total length 3.34, mean pronotum width 1.14.

ETYMOLOGY: From the generic name Maireana , the halophytic host of this species.

HOSTS: Recorded from Maireana appressa , M. georgei , M. pyramidata , Sclerolaena limbata , and Tecticornia tenuis (Chenopodiaceae) . Also recorded from Acacia sp. ( Fabaceae ) although we believe this last record to be the result of mislabeling and/or commingling of specimens in the field.

DISTRIBUTION (map 11): Widely distribution in Australia.
