Diagnosis: CHoerocoris grossi nov.sp. is recognised by the following characters: yellow, nodulate posterior angles of connexiva V-VII ( Figs 32a, b View Fig ); abdominal venter yellow with lateral and submedial black markings ( Figs 32a, b View Fig ); paratergites IX greatly enlarged, suboval ( Fig. 33e View Fig ), oblique in profile ( Fig. 33f View Fig ); gonocoxae I reduced, scythe-like, strongly incrassate medially ( Figs 33e, f View Fig ); and, male genitalia as in C. variegatus .
Description: Body moderately sized, males 10.15-11.05 mm, females 9.70-11.22 mm.
Colouration. Body bicoloured, dusty yellow, with extensive black markings ( Fig. 24c View Fig ). Head: mostly black, clypeus with a longitudinal yellow stripe (variable in length), lateral margins of jugae broadly yellow, rarely head mostly black, sometimes with green iridescence; lorae black; genae mostly yellow, sometimes with dusty embrownment. Antennae: black, sometimes with green iridescence, rarely AI proximally orange-brown. Labium: mostly yellow, LIV fuscous. Pronotum: mostly black, anterior and anterolateral margins yellow, sometimes transverse yellow stripe, submarginal to posterior margin ( Fig. 24c View Fig ). Scutellum: yellow anterior margin with subhemispherical black marking, medially with W-shaped marking, sometimes contiguous with anterior marking, posterior margin with V-shaped black marking ( Fig. 24c View Fig ). Thoracic pleura and sterna: mostly yellow, proepimeron and mesepimeron with black sublateral stripe, evaporative areas partially black. Legs: femora mostly black, with yellow markings, more so ventral surface; tibiae mostly black, sometimes with green iridescence, lateral surfaces yellow. Pregenital Abdomen: posterior angles of connexiva V-VII yellow, nodulate ( Figs 32c, d View Fig ); abdominal venter mostly yellow, lateral margins of SIV-SVII with large, subtriangular black markings, submedial regions of SIV-SVII with black suboval markings ( Figs 32a, b View Fig );. Male Genitalia: pygophore mostly yellow, with margins black ( Figs 32a, b View Fig ). Female Terminalia: mostly black, paratergites IX with prominent yellow spots.
Texture. Dorsum densely punctate.
Structure. Antennae: females, AIV longest segment, little longer than AIII; AII(a) smallest segment; AI & AII(b) subequal in length. Labium: reaching posterior margin of abdominal SIII; segments roughly subequal in length, SII longest segment. Pregenital Abdomen: connexiva V-VIII with posterior angles strongly incrassate, nodulate ( Figs 32a, b View Fig ). Male Genitalia: ventral margin of pygophore deeply excavate; CAII(L) baglike with outer margins spiculate; heavily-sclerotized, antler-like CAIII; vesica with paired, subdistal, sclerotized processes. Female Terminalia: paratergites VIII small, subtriangular ( Figs 33e, f View Fig ); paratergites IX greatly enlarged, suboval, oblique in profile ( Figs 33e, f View Fig ); gonocoxae I reduced, scythe-like, medially incrassate ( Figs 33e, f View Fig ).
Measurements. Table 7 View Table 7 .
Etymology: This species is named after Gordon Gross, in recognition of his major contribution to Australian Heteropterology.
Distribution: This species is distributed in semi-arid regions of eastern Australia, from Rockhampton (Queensland) to locations west of the Great Dividing Range in New South Wales ( Fig. 34 View Fig ).
Host plants and biology: This species has been collected on Beyeria viscosa .
Remarks: GROSS (1975) reported CHoerocoris variegatus to be composed of five subspecies; the nominotypical subspecies, C. variegatus similis , and three undescribed subspecies. We have borrowed the material on which Gross made these conclusions, and found a collection of specimens labeled as ‘ CHoerocoris variegatus subsp.nov. ’ These are conspecific with a series of specimens of the Australian Museum, from New South Wales and Queensland. These specimens can be distinguished externally from C. variegatus by the colouration of the abdominal venter, in possessing lateral and submedial bands of black colouration (cf. lateral band alone). The most conclusive diagnostic feature of C. grossi , is the female terminalia, which are unlike any species of CHoerocoris , and indeed any Australian species of jewel bug. In this species, paratergites IX are greatly enlarged, and much larger than gonocoxae I (cf. relatively small paratergites IX and large gonocoxae I), with the latter greatly reduced, with the posterior margin deeply excavate ( Fig. 33e View Fig ). Although the male genitalia of C. grossi and C. variegatus are indistinguishable, the female terminalia serve as a strong basis for species separation.

Etymology: This species is named after Professor John D. Lattin of Oregon State University, PhD supervisor of the senior author [GC], in recognition of his knowledge of the jewel bugs of the world.
Distribution: This species is known from Cape York Peninsula and the Northern Territory ( Fig. 34 View Fig ).
Host plants and biology: No host plant is known for this species.
Remarks: CHoerocoris lattini nov.sp. is most closely related to C. variegatus , on the basis of similarities of the male genitalia, particularly in the shape of the parameres and the conjunctival appendages (cf. Figs 35 View Fig and 36 View Fig ), with the former species lacking antler-like CAIII. These species are howev-er clearly differentiated by colour patterning of the dorsum (cf. Figs 24 View Fig c-f), the orange AI in C. lattini nov.sp. (dark brown in C. variegatus ), and the colour patterning of the abdominal venter (cf. Figs 32c, d and g, h View Fig ).
