Nineteen new genera and 82 new species of Cremnorrhinina from Australia, including analyses of host relationships and distributions (Insecta: Hemiptera: Miridae: Phylininae: Cremnorrhinini) Author Randall T.

Black coloration of body and appendages most similar to D. halganii , but that species with corium and clavus not entirely black and base of cuneus not contrastingly white; structure of endosomal spines also distinctive for the two species (figs. 22, 23, pl. 7). DESCRIPTION: MALE : Mean total length 2.18, mean pronotum width 0.65. COLORATION (pl. 6): Background color black, scutellum laterally, cuneus on basal half, hind femur medially, and hind tibia on apical half much paler; pygophore black, in moderate contrast to remainder of abdomen. SURFACE AND VESTITURE (fig. 19A–C): Dorsum smooth, very weakly polished and weakly shining, venter dull; dorsum clothed with short, black, reclining, simple setae. STRUCTURE: Head (fig. 19A–C, pl. 6): As in generic description; antennal segment 2 long (0.74), 1.61 times width of head. Thorax (fig. 19A–C, pl. 6): As in generic description. Pretarsus as in figure 19E, F. Hemelytron : As in generic description. GENITALIA (figs. 19D, 23, pl. 7): Pygophore: Broadly conical, posterior margin indented ventrad of left paramere insertion. Endosoma: J-shaped, basal fusion of straps on dorsal side, distal one-half bent to left; strap with stout, proximally directed spine arising laterad and distant from secondary gonopore and one apical spine with numerous conspicuous spicules over entire length; endosoma subapically expanded without inflated membrane; secondary gonopore situated just distad of middle of endosoma on margin of projecting strap. Phallotheca: Apical portion with large prominent, serrate ridge on ventroposterior surface, smooth dorsoposterior crest, and narrow trough separating ridge and crest; ridge with height subequal to crest, aperture narrow, slitlike, situated on dorsal edge; posterior surface without denticles or prominent spicules; basal portion with strong internal ridge on right side. Parameres: Left paramere with dorsoposterior margin straight, not produced dorsad of posterior and anterior processes; posterior process straight; anterior process large and rounded apically, prominent seta apparently absent; right paramere with relatively long, medial, apical projection. Fig. 23. Male genitalic structures of Dicyphylus pilbara . FEMALE (pl. 6): Coloration as in male; structure as in generic description; mean total length 2.33, mean pronotum width 0.71. GENITALIA: As in plate 43A–C. ETYMOLOGY: Named for the Pilbara Region of Western Australia, the area of the type locality; a noun in apposition. HOST: Recorded from Olearia xerophila (Asteraceae) . DISTRIBUTION (map 6): Known from the Pilbara District of Western Australia. HOLOTYPE: AUSTRALIA: Western Australia: Pilbara Dist., 21 km NW of Tom Price, 22.6513°S 117.8853°E, 712 m, 0 1 Jun 1999, G.
