Wallabicoris trymalii , new species Figure 45; map 2; plate 5

DIAGNOSIS: Among those species with numerous red spots on the dorsum, most similar to W. cuneotinctus and W. thomasii in the complete transverse fascia posteriorly on the corium, the cuneus red at least on the posterior half (pl. 5), the secondary endosomal strap with a submedial bifurcation and left paramere elongate (fig. 45) and extending

(AMNH_PBI 00089619).

well beyond the margin of the pygophore. Separated from W. thomasii by the more intense red spotting of the dorsum in that species; distinguished from W. cuneotinctus by the occurrence of that species on the south coast of Victoria instead of the extreme southwest coast of Western Australia, and from W. thomasii by feeding on Thomasia and Lasiopetalum (Sterculiaceae) rather than Trymalium (Rhamnaceae) .

DESCRIPTION: Male: Body weakly elongate, weakly ovoid, total length 4.01–4.30, l/w 5 2.99. COLORATION (pl. 5): Pronotum with posterior lobe heavily covered with red or carmine botches; scutellum with some red or carmine spots or blotches, apex pale; hemelytron with a few large red or carmine spots on anterior half of corium; solid, broad, red fascia on corium just anterior to cuneal fracture; clavus with solid red markings over most of area, partially pale near apex; cuneus pale only along cuneal fracture, solid orange or red over remaining area; membrane with elongate, contrasting, fumose marking at extreme base, remainder weakly to strongly fumose over entire area, veins white; venter unicolorous pale or mostly so; antennal segment 1 unicolorous pale, with one or two black medial setae; antennal segment 2 unicolorous pale; labium pale with segment 4 heavily infuscate; hind femora with many brown or black spots; hind tibial spines dark with very small dark bases. SURFACE AND VESTITURE: Dorsum with erect or suberect black setae, and with some sericeous or woolly setae. STRUCTURE: Head: Weakly projecting, ratio wh/lh 5 4.44; antennal fossa with ventral margin of fossa at ventral margin of eye; interocular space relatively small, ratio iod/wh 5 0.51; eyes occupying entire height of head in lateral view (hg0–1/ he20); labium very long, reaching well onto pygophore. GENITALIA (fig. 45): Endosoma: Base moderately long, with an open U-shaped bend; distal half of shaft smoothly curving; primary endosomal strap elongate apically, ratio lae/lsg 2.17; apex of primary endosomal strap weakly arcuate; secondary endosomal strap very slender, of uniform width from endosomal bend to gonopore, reaching to level of secondary gonopore, bifurcating at about midpoint; secondary gonopore seen laterally in lateral view of endosoma; fingerlike protuberance at distal margin of secondary gonopore absent. Phallotheca: Smoothly curving on dorsal margin; dorsal surface without a conspicuous keel. Left Paramere: Body elongate, somewhat exceeding pygophore margin; in dorsal perspective open over nearly entire length; body tapered toward apex, apex elongate nipplelike; anterior process arising at posterior margin of shaft; anterior process angled posterodorsally; posterior process flattened, broadest at angulate apex; posterior process with strongly projecting shoulder at base; base of posterior process at least somewhat elevated above level of paramere body. Right Paramere: Body moderately elongate, ratio lrp/wrp 3.83; body more or less parallel sided; posterior margin without distinct protuberance subapically; body elevated at juncture with base; apex with a weakly elongate fingerlike process.

ETYMOLOGY: Named for the host genus, Trymalium Fenzl (Rhamnaceae) .

HOSTS: Recorded only from Trymalium odoratissimum Lindl. subsp. odoratissimum (5 T. floribundum Steud. ) (pl. 11C), including T. f. trifidum B.L. Rye and T. f. forma fulva Steud. (Rhamnaceae) .

DISTRIBUTION (map 2): Known from areas near the coast of extreme southwestern Western Australia.

DISCUSSION: Trymalium floribundum is distributed in near-coastal areas from the vicinity of Perth south and west to about Fitzgerald River. Additional collecting might therefore extend the range of W. trymalii somewhat further along the coast in far southwestern Australia.
