Other specimens: Because of the large number of specimens examined, several hundred, the number of male and female specimens for each sample has been omitted from the collecting data. There are numerous additional specimens in various collections in Australia and overseas that have not been examined or included here.

Abdomen: Abdomen impunctate, III–V connexival segments partially exposed, extending a little beyond costal margin of closed hemelytra (Fig. 9). Abdominal terga sclerotised, pattern variable between female and male (Figs. 12 & 17). Internal apodeme on anterior margin of sternum VII in male broad and blunt, extending to ½– 2/3 length of sternum VI.
Female genitalia: Spermatheca (Fig. 14) with bulb variable from almost spherical to sub conical to conical in shape, with a flange near base sclerotised and unevenly expanded; duct part behind flange wide, gradually narrowing to a uniformly thin and extremely long tube with 10–15 twists or about 8–10 coils; basal part of duct narrow, tubular. Ovipositor as in Figs. 15 & 16.
Male genitalia: Pygophore as in (Fig. 19). Paramere with blade broad, bluntly pointed towards apex, and with a few long setae near base, more so on ventral aspect (Figs. 24–26). Aedeagus (Figs. 20–22) with phallotheca moderately to heavily sclerotised in a basal broad band, particularly prominent on dorsal aspect; conjunctiva tubular, membranous, gradually narrowed towards upper end; body and wings of ejaculatory reservoir well developed, neck well developed and produced behind laterally in a wing-like pattern (Fig. 23). Vesica distally near helicoid process with small elongate sclerites and processes along margin, the processes (often irregular) varying from a narrow I-shape to a broad H-shape. Gonoporal process beyond helicoid process very thin, with 8–12 small uniform coils; secondary gonopore simple, not flaring (Fig. 22).
Distribution. Distributed in all Australian states and territories.
Notes. This species has some similarities with G. kinbergi Stål, the type species of the genus Germalus, in general facies and general colouration including a fuscous spot on each humeral angle of pronotum, but differs by having a very long narrow coiled spermathecal duct (short, uncoiled in G. k i n b e rg i) and lacking vague roundish fuscous spots on each pronotal callus.
This species as redescribed in this contribution is extremely variable in colour and structure. Some specimens are generally darker in general body colour. The pronotum in some specimens has faint, patchy, vague fuscous punctures in six incomplete rows: 2 in middle, and 4 on the lateral / sublateral sides (this is variable even within one series). In some specimens the apical angle of the clavus and of the corium, and a spot at the apical margin of the connexival segments, are black; the abdominal tergum with three narrow vittae to the penultimate segment, a narrow fascia connecting the posterior ends of these vittae, and a broad median vitta to the last dorsal segment, and the male genital segment, are fuscous; these abdominal markings are well visible through the translucent membrane.
There is also variation in number and intensity of punctures on clavus and corium. In some specimens the clavus has an almost complete row of punctures on its outer margin (e.g., Stanley and Donnybrook in Victoria; Mt Arthur and Launceston in Tasmania; Mt Remarkable and Burra Creek in South Australia). In other specimens this row is more or less incomplete at least in apical third. In others, punctures on the corium are almost indistinct. The labium may extend to middle coxae (Tullarine Well, SA; Normanton, Qld), to middle to hind coxae (Normanton), or to hind coxae (Lake Eyre, SA). Shape of the spermathecal bulb varies from spherical (Nullarbor Plains, SA; all specimens from Victoria), to almost spherical (Tullarine Well), to slightly conical to conical (Normanton; Lake Eyre). Coiling in the male gonoporal process varies from 6 coils (Normanton; Lake Eyre), to 10–15 (Tullarine Well), to 15–20 in a tightly coiled, extremely long and narrow process (Quilpie, Qld).
