Thaumastocoris hackeri is recognised by the combination of the following characters: body elongate; eyes strongly pedicellate; mandibular plates weakly concave and moderately expanded laterally; labium elongate, reaching posterior region of prosternum; corium laterally expanded beyond claval commissure; abdomen laterally expanded and visible dorsally visible beyond costal margin of hemelytra ( Figure 4 C,D); paramere elongated into a hornlike projection apically ( Figure 18 E,F). Thaumastocoris hackeri can be distinguished from T. roy , a species with a similar body shape and elongate labium, by the paramere (cf. Figure 19 D). The paramere of T. roy forms a keel apically and is not hornlike. In addition, T. hackeri is much larger in size than T. roy . Redescription. Submacropterous. Male length 2.96–3.24, width 0.98–1.23; female length 3.24–3.36, width 1.23–1.35. Females slightly larger in size and darker in colouration. Colouration . Dorsum straw-coloured to yellowish brown, with contrasting dark brown markings ( Figure 4 C,D). Head : mostly straw-coloured; sublateral margins darker; gula dark brown. Antennae : mostly straw-coloured; apical half of AIII and all excluding basal eight of AIV dark brown to fuscous. Labium : mostly yellowish brown; LIII and LIV darker brown. Pronotum : mostly yellowish brown; pronotal disc yellowish cream, medially with dark brown. Thoracic pleura and sterna : mostly yellowish brown, propleura yellowish brown paler dorsally; prosternum fuscous; mesosternum dark brown, paler laterally. Scutellum : straw-coloured, anterior margin yellowish brown. Hemelytra : mostly straw-coloured, medial margin of corium often darker; membrane straw-coloured, medially infused with dark brown ( Figure 4 C,D). Legs : mostly yellowish brown, second tarsomere light brown. Abdomen : uniformly yellowish brown. Texture . Dorsum moderately polished, with shallow to deeply set setose punctures. Head : irregularly punctuate ; vertex mostly impunctate, with three transverse puncticulate rows, punctures shallow; epicranial suture with irregular distribution of fine punctures; mandibular plates with regular distribution of punctures, bare anteriorly. Pronotum : callosite region irregularly punctate, punctures shallow, midline with fine dense punctures, anterolateral angles with sparse shallow punctures; disc densely and regularly punctate, punctures deep, posterolateral angles impunctate. Thoracic pleura and sterna : pleura with uniform dense shallow punctures; mesosternum strongly polished medially. Scutellum : densely and regularly punctate, punctures deep, midline polished posteriorly. Hemelytra : clavus and corium with uniform moderate distribution of deep punctures, larger than on pronotal disc. Abdomen : impunctate, moderately polished. Vestiture . Dorsum with uniform distribution of setose punctures, setae short and straw-coloured. Lateral aspects of body uniformly clothed with short straw-coloured, erect setae. Ventral surface with short sparse setae, becoming bare medially. Antennae : AII–AIII with uniform distribution of fine, erect setae; AIV with same seta on lateral margins, sparse on dorsal and ventral surface. Male genitalia : pygophore clothed in fine setae; pygophoral lock with dense setae apically; paramere with setae medially, horn nude ( Figure 18 E,F). Structure. Head : mandibular plates elongate, surpassing clypeus by less than clypeal length, contiguous medially, weakly flared anteriorly, weakly concave dorsally, anterolateral margins weakly recurved; genae swollen; bucculae strongly arcuate; gula weakly concave. Eyes : strongly pedicellate, recurved ( Figure 4 C,D). Antennae : AI to AIII cylindrical; AIV weakly dorsoventrally flattened. Labium : elongate, reaching towards posterior margin of prosternum. Pronotum : weakly constricted medially; callosite region shorter than disc, disc broader; anterolateral angles weakly arcuate; lateral margin of disc weakly arcuate; disc slightly raised above callosite region ( Figure 4 C,D). Thoracic sterna and pleura : prosternum moderately expanded ventrally; propleura concave medially, posterolateral margins reduced. Hemelytra : at rest extending to abdominal TIX; corium expanded beyond claval commissure, medial margin of corium weakly excavate distally, apex of corium at membrane narrowed, medial margin more than 45° to costal margin ( Figure 4 C,D). Legs : forecoxal separation less than coxal width; fore and mesofemora strongly incrassate; fossula spongiosa elongate, reaching distal margin of second tarsomere; 15–20 foretibial teeth, 12–18 mesotibial teeth, 5–6 metatibial teeth. Male Genitalia : pygophoral lock elongated, expanded apically; paramere ovate with horn like projection apically ( Figure 18 E,F). Measurements. See Table 2. Distribution. This species is distributed from temperate to tropical eastern Australia ( Figure 20 A); from just north of Sydney to Kuranda. Host plant. Thaumastocoris hackeri has been collected from a wide range of host plants, and among thaumastocorids shows some of the widest phylogenetic diversity in plant families ( Table 3 ). It has been collected in Kuranda from an unidentified plant in the Rubiaceae . Near Landsdowne in New South Wales it was found on the blossoms of Schizomeria ovata (Cunoniaceae) . Rose (1965) also collected it from Elaeocarpus obovatus (Elaeocarpaceae) . Remarks. The paramere of Thaumastocoris hackeri has an apical hornlike projection which is unique to this species and quite elaborate in comparison to other species of Thaumastocoris .
