Detail of left paramere and apex of pygophore, dorsal view (AMNH_PBI 00128841). elongate (fig. 40), similar to W. cuneotinctus , W. pultenaei , W. thomasii , and W. trymalii . DESCRIPTION: Male : Body elongate ovoid, total length 3.93–4.12, l/w 5 2.87. COLOR- ATION (pl. 5): Pronotum pale with a few red Fig. 40. Wallabicoris spyridiellus , male genitalia (AMNH_PBI 00128858). spot; scutellum pale, sometimes with a few red spots; hemelytron with scattered red spots; complete, transverse, red fascia on corium present just anterior to cuneal fracture; markings on cuneus sometimes present as a few red spots; membrane with elongate, contrasting, fumose marking at extreme base, remainder 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 suberect black setae, especially on pronotum, intermixed with pale setae on hemleytron, and with some sericeous or woolly setae. STRUCTURE: Head: Weakly projecting, ratio wh/lh 5 4.47 (fig. 39A); antennal fossa with ventral margin 1 diameter above ventral margin of eye; interocular space relatively small, ratio iod/wh 5 0.48; eyes leaving gena moderately exposed in lateral view (hg3/ he20); labium very long, reaching well onto pygophore. GENITALIA (fig. 39E, F, 40): Endosoma: Base very long, with an open Ushaped bend; distal half of shaft smoothly curving; primary endosomal strap elongate apically, ratio lae/lsg 2.40; 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 frontally in lateral view of endosoma. Phallotheca: Smoothly curving on dorsal margin; dorsal surface with a conspicuous keel. Left Paramere: Body very elongate, greatly exceeding margin of pygophore; 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; posteri- or process with strongly projecting shoulder at base; base of posterior process at least somewhat elevated above level of paramere body. Right Paramere: Body elongate and slender, ratio lrp/wrp 4.00; body more or less parallel sided; posterior margin without distinct protuberance subapically; body more or less confluent with base; apex with short fingerlike process. ETYMOLOGY: Named for the host genus, Spyridium Fenzl (Rhamnaceae) . HOSTS: Recorded only from Spyridium globulosum (Labill.) Benth. (Rhamnaceae) (pl. 11A, B). DISTRIBUTION (map 2): Known from the Esperance area of south coastal Western Australia . DISCUSSION: Spyridium globulosum has a coastal distribution ranging from Shark Bay in the Northwest to somewhat east of Esperance. We might therefore predict a wider distribution for W. spyridiellus on the basis of the host distribution.
