Holotype male, Australia , Queensland , Lake Broadwater via Dalby , site 3, 22-25.ii.1986 , G. Monteith & G. Thompson ( QM ) . Paratypes : QUEENSLAND . 1 female , same data as holotype except site 7 ( QM ); 1 macropterous male, same data as holotype except site 6, at MV light, 22.ii.1986 ( QM ); 1 macropterous male, Lake Broadwater via Dalby, 19.ii.1985 , G. I. Thompson ( QM ) . Description. As in E. fuscatus sp. nov. above, except: Brachypterous male ( Fig. 21 ) and female Colouration: Black, with yellow as follows: connexiva both dorsally and ventrally with about one third anterior area of segments III–VII, dorsally yellow not extending to entire width of connexiva, and brachypterous hemelytra with large median area including most of clavus yellow (but surrounded by fuscous narrow lateral and broad anterior and broader posterior area, latter area not distinctly fuscous in female). Structure: Brachypterous hemelytra extending to about half length on second (female) to about one third length on third (male) abdominal tergite ( Fig. 21A ). Macropterous male ( Fig. 22 ) Colouration ( Fig. 22 ): Black, with yellow as follows: connexiva as in brachypterous but present on segments II–VII, and corium and clavus (excluding narrow basal area, and irregular apical and posterior marginal areas of corium and all of membrane fuscous). Other details as in brachypterous form except ocelli and ocellar tubercle area slightly more prominent, collar process of anterior lobe of pronotum more prominent, and hemelytra well exceeding abdomen, almost entirely covering connexiva ( Fig. 22A ). All other structural details as in E. fuscatus sp. nov. Measurements: [of holotype male brachypterous, followed by paratype male macropterous]. Body length 9.67, 11.54; maximum width of abdomen 2.96, 3.12; length of head 1.78, 1.82; length of anteocular region 0.79, 0.87; length of postocular region 0.30, 0.34; width of head across eyes 1.21, 1.21; width of interocellar space 0.20, 0.19; length of eye in dorsal view 0.60, 0.57; width of eye in dorsal view 0.38, 0.34; lengths of antennal segments I–IV 0.95, 0.95 / 1.71, 1.82 / 1.48, 1.63 / 1.55, 1.71; length of visible labial segments I–III 0.57, 0.57 / 1.06, 0.95 / 0.57, 0.64; length of pronotum 2.47, 2.66; length of anterior pronotal lobe 1.93, 1.82; length of posterior pronotal lobe 0.50, 0.79; length of scutellum 0.91, 1.14; maximum width of scutellum 0.76, 1.25; length of hemelytra 2.35, 7.48; length of fore tibia 1.90, 1.95; length of fossula spongiosa on fore tibia 1.33, 1.35. Distribution. Australia ( Queensland ). Etymology. The species epithet is the Latin adjective luteolus (meaning ‘yellowish’; formed from luteus +Γ the diminutive suffix - olus ), in allusion to the colour of the apical portion of the clavus. Notes. This species is very close to E. fuscatus sp. nov. , but readily distinguished by the colouration of the clavus in both macropterous and brachypterous forms. In this species, apical almost 3/4 of the clavus is yellow like most of the corium ( Figs. 21A , 22A ) whereas in E. fuscatus sp. nov. , the entire clavus is fuscous in contrast to most of the corium yellow ( Figs. 11A&D , 12A ).
