Bifidostylus newmanensis , new species

Figure 15, map 5, table 1, plates 4, 5

DIAGNOSIS: Recognized by the moderate size (mean total length male 3.53), green coloration, translucent hemelytron, the black setae on the dorsum (pl. 4), and the J-shaped endosoma with narrow sclerotized subapical secondary gonopore and apically straight endosomal straps (fig. 15, pl. 5). Endosomal structure most similar to that of B. finalis and B. gawlerensis in being J-shaped and with equal-length straps. Distinguished from B. finalis by the almost transparent hemelytron and weakly darkened setae in that species; shares with B. gawlerensis the green coloration, translucent hemelytron, and black setae on the dorsum, but differing from B. gawlerensis by that species having distally wavy endosomal straps.

DESCRIPTION: MALE: Weakly elongate, parallel sided, mean total length 3.53, mean pronotum width 1.05. COLORATION (pl. 4): Pale green (yellow to orange in some preserved specimens); membrane weakly fumose. SUR- FACE AND VESTITURE (pl. 4): Dorsum weakly polished and shining, weakly crenulate, covered with recumbent, black, simple setae. STRUCTURE: Head (pl. 4): Eyes large, protuberant, vertex moderately broad; frons not inflated, slightly surpassing anterior margin of eye; eye occupying three-quarters height of head; antenna inserted somewhat above ventral margin of eye, eye slightly emarginate; antennal segment 2 relatively short (1.06), 1.17 times width of head; labium reaching to apex of procoxa. Thorax (pl. 4): Pronotum with anterior lobe demarcated, calli distinct, posterior lobe flat to very weakly elevated, lateral and posterior margins very weakly concave; mesoscutum moderately exposed. Hemelytron: Not obviously elongate, corial margin nearly straight, cuneus at most weakly elongate, triangular. GENITALIA (fig. 15, pl. 5): Pygophore: Elongate conical. Endosoma: J-shaped, straps contiguous and parallel, dorsal strap bifid subapically with two narrow, equally thick spines of subequal length extending beyond secondary gonopore by length of gonopore; ventral strap bifid medially, terminating proximad of secondary gonopore, shorter and thinner than dorsal strap, narrow and of equal thickness throughout, except attenuate apically; interstrap membranous region narrow; secondary gonopore narrow, well sclerotized. Phallotheca: Apical portion elongate conical, somewhat broadened subapically, compressed or flattened in dorsal view, aperture elongate triangular; basal portion long, reaching beyond anterior margin of pygophore in situ.

Parameres: Left paramere with dorsoposterior margin strongly elevated above anterior and posterior processes with broad dorsal protuberance; posterior process long, undulating in lateral view and sinuous in dorsal view; anterior process small, slightly produced beyond surface of paramere, long seta present ventrad of anterior process. Right paramere somewhat swollen with well-defined bifid apex.

FEMALE (pl. 4): Elongate elliptical, costal margin of hemelytron weakly convex; mean total length 3.32, mean pronotum width 1.00. Coloration, surface, and vestiture similar to male. Eyes much smaller than in male, vertex broad; frons modestly inflated and slightly projecting beyond anterior margin of eye.

HOST: Recorded from Eremophila alternifolia (Scrophulariaceae) .

DISTRIBUTION (map 5): Known only from the type locality, Newman Rocks, east of Norseman, Western Australia, on the Eyre Highway.
