Wallabicoris sandstonensis , new species Figure 37; map 4; plate 5

DIAGNOSIS: Recognized among those species with heavily yellow coloration by the faded yellow dorsum (pl. 5), by the relatively small size, mean total length 4.50, the head conspicuously projecting beyond the anterior margin of the eyes, ratio head length/head width 2.58, the left paramere greatly elongate and strongly projecting beyond margin of pygophore (fig. 37), and the secondary endosomal strap with a very broad and deep submedial undulation (fig. 37). Host unknown. Similar to W. waitzii in the elongate left paramere strongly projecting beyond the margin of the pygophore, but coloration of dorsum in W. waitzii more uniformly and intensely yellow and the body much more strongly elongate than in W. sandstonensis . Distinguished from W. chrysocephali , W. maralinga , and W. rutidosi by the much shorter, more deep-bodied left paramere in those species only moderately projecting beyond the margin of the pygophore. Potentially confused with W. commoni , that species with uniform yellowish coloration, but larger with a mean total length of 5.60; secondary endosomal strap with a broad subbasal undulation similar to that seen in W. sandstonensis , but left paramere in W. commoni much more deep bodied than in W. sandstonensis .

DESCRIPTION: Male: Body moderately elongate, nearly parallel sided, total length 4.25–4.70, l/w 5 3.29. COLORATION (pl. 5): Pronotum unicolorous yellow; hemelytron mostly yellow, endocorium with dirty areas; markings on cuneus present as partial but weak infuscation on posterior half; membrane with elongate, contrasting, fumose marking at extreme base, remainder weakly fumose over entire area, veins white; venter light yellow; antennal segment 1 yellow, with one or two black medial setae; antennal segment 2 yellow; labium pale with segment 4 heavily infuscate; hind femora unicolorous pale, without black spots; hind tibial spines dark without dark spots at bases. SURFACE AND VESTITURE: Dorsum with reclining simple setae matching background coloration, without sericeous or woolly setae. STRUCTURE: Head: Elongate, projecting anteriorly, ratio wh/lh 5 2.56; antennal fossa with ventral margin of fossa at ventral margin of eye; interocular space relatively small, ratio iod/wh 5 0.49; eyes leaving gena moderately exposed in lateral view (hg3/he20); labium just reaching onto abdomen. GENITALIA (fig. 37): Endosoma: Base very long, with a tight U-shaped bend; distal half of shaft more or less straight and erect; primary endosomal strap elongate apically, ratio lae/lsg 2.18; 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, with a broad submedial undulation; secondary gonopore seen laterally in lateral view of endosoma. Phallotheca: More or less right angulate, dorsal surface without a hump; dorsal surface without a conspicuous keel. Left Paramere: Body very elongate, greatly exceeding margin of pygophore; in dorsal perspective closed over about threefourths 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 elongate, ratio lrp/wrp 3.32; body tapered from base to apex; posterior margin without distinct protuber-

ance subapically; body more or less confluent with base; apex with short fingerlike process.

ETYMOLOGY: Named for the town of Sandstone, near the type locality.

HOSTS: Unknown.

DISTRIBUTION (map 4): Known from the Goldfields region of Western Australia.
