Eremotylus stuarti , new species

Figure 30, map 7, table 1, plates 8, 9, 44

DIAGNOSIS: Recognized by the moderate size (mean length 3.08), elongate oval body, translucent hemelytron, and uniform green coloration in living specimens (pl. 8). Endosoma moderately elongate, almost U-shaped, weakly twisted, with one long, straight, erect broad spine and two short, slender spines subtending the secondary gonopore (fig. 30); left paramere with a distinctly undulating posterior process (fig. 20). Easily confused with E. glaber on the basis of size, coloration, and genitalic structure, but that species with long apical spine at a right angle to distal third of endosoma and one short spine arising at distal edge of gonopore rather than subtending it; posterior process of left paramere undulating as in E. betoota and E. glaber .

DESCRIPTION: Male: Mean total length 3.08, mean pronotum width 0.89. COLORATION (pl. 8): Light green in life, changing to weakly yellow when preserved, hemelytron almost opaque; membrane pale to weakly fumose. SURFACE AND VESTITURE (pl. 8): Dorsum smooth, weakly shining; vestiture of reclining, dark, common setae.

STRUCTURE: Head (pl. 8): Short, moderately broad, eyes of moderate size, frons not or only weakly swollen and only slightly projecting anterior to eye, eye occupying slightly less than two-thirds height of head; antenna inserted just above ventral margin of eye, eye weakly emarginate at and above insertion; antennal segment 2 moderately long and stout (0.91), not noticeably swollen, 1.36 times width of head; labium somewhat surpassing posterior margin of mesosternum. Thorax (pl. 8): Mesoscutum narrowly exposed. Hemelytron: Weakly elongate, costal margin very weakly convex, cuneus weakly elongate. GENITALIA (fig. 30, pl. 9): Pygophore: Elongate conical, dorsal surface anteriad of aperture with narrow tubercle on left side; single long bristle anteroventrad of each paramere insertion. Endosoma: Region distad of secondary gonopore strongly bent to left; dorsal strap bifid proximal of secondary gonopore, apically with one short, slender, erect spine and one long, straight spine; ventral strap terminating in subapical point subtending secondary gonopore. Phallotheca: Apical portion narrow, dorsal margin without crest, aperture narrow slitlike, situated on anterodorsal margin and continuous across apex. Parameres: Left paramere elongate with medial portion of dorsoposterior margin produced; posterior process bent with undulating lateral margin; anterior process minute, pointed; long seta situated on anterior process. Right paramere narrowed apically, apex with three small points.

Female (pl. 8): Mean total length 2.78, mean pronotum width 0.89; antennal segment 2 more slender than in male. GENITALIA as in plate 44.

ETYMOLOGY: Named after John McDouall Stuart, Central Australian explorer.

HOST: Recorded from Eremophila macdonnellii (Scrophulariaceae) .

DISTRIBUTION (map 7): Known from the Alice Springs region of Central Australia.
