( Figures 55 , 62–64 , 65–67 )

Type-species: Poppiomegacoelum gearyi Malipatil & Chérot sp. nov. (present designation).

Description. Body 6.5–7, sub-oblong, slightly convex, almost uniformly orange brown, with yellow areas ( Fig. 55 ). Head gradually sloping anteriorly, in lateral view the tylus is distinctly curved and joined to frons without a notch. Sulcus of vertex distinct, relatively deep. Vertex not carinate. Eyes wide, particularly in males. First antennal segment slightly club-like and curved. Labium reaching mid coxae. Pronotum dorsally pilose, with a shining collar and a pair of stiff, semi- erect white setae on anterior corners. Scutellum relatively flat, slightly tumid and shagreened. Pilosity of metatibia semi-erect, short. Tibial spines light brown. Dorsal pilosity relatively long, recumbent to semi-erect, white, particularly dense on scutellum and hemelytra. Hemelytra slightly reflective, opaque, almost smooth, their punctation shallow and relatively wide. Veins raised. Primary apophysis of right paramere with two pointed lobes. Phallus devoid of comb or true spiculum but provided with a wide, elongate phallic support. Secondary gonopore complete, devoid of sclerite, hairs or pilose plate. Parieto-vaginal rings thin, devoid of anterior projections, dorso-labiate and ventral labiate plates wide, margins reinforced. Dorsal wall bearing a pair of sclerites.

Included species. P. g e ar y i n. sp*.

Distribution. Australia.

Host plants. Unknown.

Discussion. By the habitus, the genera Poppiocapsidea and Poppiomegacoelum are relatively similar. They differ mainly by the pronotal pilosity (almost absent in Poppiocapsidea , but present in Poppiomegacoelum ) and the male genitalia (secondary gonopore incomplete in Poppiocapsidea , but complete in Poppiomegacoelum ; gonoporal pilose plate present in Poppiocapsidea , but absent in Poppiomegacoelum ; phallic support and additional sclerites absent in Poppiocapsidea , but present in Poppiomegacoelum ).
