Etymology. Named in honour of Jennifer Moore for her substantial support in field and laboratory investigations of Thaumastocoris species. The suffix, freo, reflects her passion for the Fremantle Football Club.

Diagnosis. Thaumastocoris freomooreae is recognised by the following combination of characters: body narrow, costal margins subparallel (Figure 4 A,B); mandibular plates gently and evenly rounded (Figure 11 A); labium moderately long (Figure 11 B); pronotal constriction weak, with truncate to rounded anterolateral angles (Figure 4 A,B; 11A); pygophoral lock weakly trapezoidal; paramere subrectangular, apically recurved. (Figure 18 C). This species is distinguished from T. majeri and T. ohallorani by its longer labium. The labium of T. freomooreae reaches the anterior margin of the forecoxae, whereas the labium of T. majeri and T. ohallorani is shorter, just extending past the anterior margin of the prosternum in both the last two species. In addition, the paramere of T. freomooreae is recurved apically, whereas the paramere of both T. majeri and T. ohallorani is spatulate apically (cf. Figure 18 D,G,H).
Description. Submacropterous. Male length 2.45–3.00, width 0.62–0.93; female length 2.77–3.12, width 1.01–1.17. Females larger in size, abdomen greatly expanded beyond costal margins. Colouration. Dorsum yellowish brown with contrasting dark brown to fuscous markings (Figure 4 A,B). Head: mostly yellowish brown; vertex golden yellow to medium brown; lateral aspects of mandibular plates and genae with fuscous stripe; genae, gula and bucculae straw-coloured. Antennae: mostly yellowish brown; subapical half to two-thirds of AIII and apical two-thirds of AIV dark brown to fuscous; female AIII and AIV sometimes less darker. Labium: LI–LIII strawcoloured; apex LIV fuscous. Pronotum: mostly yellowish brown; pronotal disc cream-coloured medially (Figure 4 A,B). Thoracic pleura and sterna: mostly yellowish brown; prosternum fuscous, paler at anterior margin; mesosternum fuscous medially becoming paler laterally. Scutellum: dark brown anteriorly, posterolateral margins paler, posterior half of midline straw-coloured. Hemelytra: yellowish brown, with clavus more cream-coloured; membrane cream, medially infused with brown (Figure 4 A,B). Legs: mostly straw-coloured, with distal half of second tarsomere dark brown. Abdomen: uniformly yellowish brown. Texture. Dorsum moderately polished, with scattered shallow to deep setose punctures. Head: vertex mostly impunctate, with transverse puncticulate rows; epicranial suture with irregular distribution of moderately deep punctures; mandibular plates irregularly punctate, denser posteriorly, punctures shallow (Figure 11 A). Pronotum: callosite region sparsely punctate, punctures shallow, denser along midline and at anterolateral angles; disc densely and regularly punctate, punctures deep, posterolateral angles impunctate (Figure 11 A). Thoracic pleura and sterna: proepimeron finely punctate posteriorly; metapleuron with irregular distribution of fine punctures posteriorly (Figure 11 E); thoracic sterna impunctate, mesosternum strongly polished medially. Scutellum: densely and regularly punctate, punctures deep, midline polished posteriorly. Hemelytra: clavus and corium with uniform distribution of deep punctures, larger than on pronotal disc (Figure 11F). Abdomen: impunctate moderately polished. Vestiture. Dorsum with uniform distribution of setose punctures, setae, short, erect, straw-coloured. Ventral surface of body with fine, straw-coloured, decumbent setae, most densely distributed on ventral aspect of mandibular plates, gula, and prosternum (Figure 11 B); mesosternum with irregular distribution of fine setae medially, sparse laterally. Antennae: uniform distribution of decumbent setae, intermixed with fine, erect setae; AIII and AIV with same setae on lateral margins, otherwise bare (Figure 11 C). Legs: dorsal surface of femora and tibia with short, erect setae. Male Genitalia: pygophore with irregular distribution of fine setae; pygophoral lock irregularly setose medially, margins mostly bare; paramere evenly beset with setae medially, becoming sparse apically (Figure 18 C). Structure. Head: mandibular plates elongate, surpassing clypeus by less than length of clypeus, contiguous medially, moderately flared anteriorly, concave dorsally, with lateral margins moderately recurved (Figure 4 A,B; 11A); bucculae strongly arcuate, weakly explanate posteriorly (Figure 11 B); genae swollen, truncate anteriorly; gula concave. Eyes: moderately pedicellate (Figure 4 A,B: 11A). Antennae: AI cylindrical; AII slightly expanded distally; AIII and AIV dorsoventrally flattened; AIV weakly lanceolate (Figure 11 C). Labium: moderately long, reaching beyond anterior margin of forecoxae (Figure 11 B). Pronotum: weakly constricted medially; callosite region and disc subequal in length, disc a little broader; callosite region weakly depressed along midline; anterolateral angles rounded to weakly tuberculate; lateral margin of disc weakly arcuate (Figure 11 A). Thoracic sterna: prosternum weakly concave medially (Figure 11 B). Hemelytra: at rest extending to basal third of pygophore; medial margin of corium convex medially, weakly excavate distally; apex of corium at membrane narrowed, medial margin less than 45° to costal margin (Figure 4 A,B). Legs: forecoxal separation equal to slightly wider than coxal width; fore and mesofemora strongly incrassate (Figure 11 B); fossula spongiosa elongate, reaching distal third of second tarsomere (Figure 11 B,D); 3–8 foretibial teeth, 0–6 mesotibial teeth, metatibiae bare. Male Genitalia: pygophoral lock moderately elongate, subtrapezoidal, with apical angle strongly flared, medial angles weakly pointed; paramere subrectangular, apical angle recurved (Figure 18 C).
Measurements. See Table 2.
Distribution. Thaumastocoris freomooreae is distributed through southern Australia; collected from northwest Victoria (Figure 2 B), south eastern South Australia, and Cocklebiddy on the southeast coast of Western Australia, and northeast of Perth, Western Australia (Figure 20 A).
Host plants. This species is known from fifteen species of Eucalyptus (Table 3).
Remarks. Thaumastocoris freomooreae is known from drier environments. From one collecting event in Highbury, Western Australia, this species was taken in conjunction with T. nadeli on Eucalyptus wandoo. The specimens collected from the goldfields district in Western Australia (Westonia), are slightly smaller and paler than other populations of T. freomooreae.
