DIAGNOSIS: Among those species with numerous red spots on the dorsum (pl. 5), most similar to W. spyridiellus in the largely pale cuneus, although W. spyridiellus always with a complete red transverse fascia posteriorly on the corium and sometimes with red spots on the cuneus; similar to W. rhamnicola in the left paramere being short, deep bodied, and blunt apically, secondary endosomal strap incomplete, with a large gap between proximal end of secondary gonopore and remainder of strap (fig. 42); the broken strap also seen in a similar form in the Rhamnaceae feeder W. pomaderri , but that species without red spots on the dorsum and with an apically acuminate left paramere, and in W. rutidosi , but in that species the strap broken medially and with a relatively long section attached to the secondary gonopore.

DESCRIPTION: Male: Body weakly elongate, weakly ovoid, total length 3.64–3.82, l/ w 5 2.95. COLORATION (pl. 5): Pronotum pale with red botches and spots; scutellum deep red; hemelytron mostly red on medial area of clavus; partial red fascia present on endocorium corium and clavus present anterior to cuneal fracture; membrane with elongate, contrasting, fumose marking at extreme base, remainder weakly fumose over entire area, veins white; venter heavily red laterally; antennal segment 1 yellow to dirty yellow, with one or two black medial setae; antennal segment 2 yellow to dirty yellow; 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 reclining black setae, especially on pronotum, intermixed with pale setae on hemleytron, and with some sericeous or woolly setae. STRUCTURE: Head: Somewhat projecting, ratio wh/lh 5 3.51 (fig. 41A); antennal fossa with ventral margin of fossa at ventral margin of eye; interocular space relatively small, ratio iod/wh 5 0.50; eyes leaving gena moderately exposed in lateral view (hg3/he20); labium reaching to margin of pygophore. GENITALIA (fig. 41E, F, 42): Endosoma: Base very long, with a tight U-shaped bend; distal half of shaft smoothly curving; primary endosomal strap elongate apically, ratio lae/lsg 2.25; apex of primary endosomal strap distinctly curving; secondary endosomal strap very slender, of uniform width from endosomal bend to gonopore, reaching midway to gonopore from major bend in endosoma; secondary gonopore seen frontally in lateral view of endosoma. Phallotheca: Smoothly curving on dorsal margin; dorsal surface without a conspicuous keel. Left Paramere: Body relatively short, just exceeding margin of pygophore; in dorsal perspective closed over about one-half length; body not distinctly tapering toward apex; anterior process arising at posterior margin of shaft; anterior process angled posterodorsally; posterior process appearing tubular, fingerlike; 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

(AMNH_PBI 00129916).

elongate, ratio lrp/wrp 3.93; body more or less parallel sided; posterior margin without distinct protuberance subapically; body elevated at juncture with base; apex with short fingerlike process.

ETYMOLOGY: Named for its host genus, Spyridium Fenzl (Rhamnaceae) .

HOSTS: Recorded from Spyridium sp. and S. vexilliferum (Hook.) Reissek (Rhamnaceae) . The very few specimens from Calytrix tetragona Labill. (Myrtaceae) and Eutaxia (Fabaceae) are certainly the result of mislabeling or commingling of specimens in the field.

DISTRIBUTION (map 2): Known from southeastern South Australia.

DISCUSSION: Spyridium vexilliferum has a distribution ranging from Eyre Peninsula southeast onto Tasmania, seldom occurring more than about 100 km from the coast. We might therefore predict a wider distribution for W. spyridiellus on the basis of the host distribution.

The material listed under ‘‘Other Specimens Examined’’ [33 (00087235, 00130194– 00130195), 5♀ (00130196–00130198, 00130402, 00367955)] bears the same host labeling as many specimens treated as paratypes and has near identical male genitalic structure. Nonetheless, the coloration of the dorsum is almost entirely red-orange, with a few spots distinguishable on the head and anterior lobe of the pronotum. Additional fieldwork and host information should clarify whether these specimens represent the range of coloration in W. spyridii or whether they are a distinct taxon.
