Redescription.

Macropterous male ( Fig. 26 )

Colouration ( Fig. 26 ): Generally bi-coloured, head, pronotum, scutellum, thoracic pleura, extreme base and most of posterior area of abdominal venter and dorsum black with bluish tinge particularly on ventral aspect. Abdomen with entire segments II & III and adjoining part of IV, connexiva with anterior area one third to half of segments IV–VI and entire connexivum of VII brownish yellow. Antennae, labium and legs generally orange (except coxal bases black and often distal third to half of hind femur and occasionally also entire hind tibia fuscous brown). Hemelytra orange except clavus and inner narrow area of corium adjoining distal 2/3 length of clavus fuscous; membrane fuscous except one whitish spot located on basal area of AIC and extreme apical area paler. Abdomen with basal areas of connexiva of IV-VI narrowly fuscous.

Scutellum and pronotum shiny smooth. Head and body including abdomen generally covered with fine short pubescence, with sparse longer bristles obvious on appendages.

Structure ( Figs. 26–29 ): Body medium to large, elongate.

Head: elongate fusiform, wholly covered with short whitish pilosity and sparse longer bristly setae prominent on mandibular plates, dorsal aspect of head and between eyes, and on dorsal aspect of first labial segment. Anteocular region elongate triangular, clypeus near its base slightly elevated knobbed above mandibular plates. Interocular region with arcuate convex sulcus at posterior border of eyes, and with a small median pit. Postocular region gradually rounded to neck. Ventral surface of head tumid before eyes. Ocellar tubercle distinct. Antennae with all segments cylindrical, with short whitish pilosity and sparse longer setae. Scape thickest, pedicel thinner towards distal end, then basi-and distiflagellum thinnest. Eyes moderately large, reniform, not reaching ventral margin in lateral view. Ocelli large, conspicuously raised, separated from each other by less than diameter of single ocellus, separated from eye by about similar distance. Labium with second and third visible segments sparsely covered with longish setae.

Thorax: Anterior lobe of pronotum with collar armed with rounded and obvious tubercles at lateral ends, integument smooth, sulci indistinct, except shallow middle long sulcus in basal half. Posterior pronotal lobe short, arcuately quadrate, integument finely rugulose, with short pilosity, humeri rounded, posterior margin almost smoothly rounded, posterior angles not developed. Scutellum with disc slightly depressed, sides carinate, integument pilose, armed with strongly pointed and upwardly projected apex. Meso-and metanotum generally also rugulose carinate not smooth. Propleuron with integument faintly granulate but not smooth, pilose, set off from dorsal surface by a carina. Mesopleuron integument minutely granulate, sparsely pilose. Metapleuron with integument more distinctly granulate but granules not striate, metapleural sulcus distinctly bicarinate and curved, pilose with silvery dense hairs posteriorly. All sternites more or less smooth, moderately pilose. Pronotum densely pilose laterad of labial groove. Mesosternum with disc raised, metasternum with disc more or less tumid.

Legs: Fore leg with coxa contiguous, with whitish pilosity; trochanter unarmed, sparsely hairy; femur strongly fusiform, greatly incrassate near base narrowing distally, much thicker than other femora, armed below with rows of bristly setae, in addition sparsely pilose laterally and above; tibia cylindrical, more or less straight but apex slightly reflexed, fossula spongiosa occupying about half of tibial length; tarsi with denser short pilosity ventrally. Mid leg with coxa globular, femur only slightly thickened, tibia with short whitish pilosity for whole length, with fossula spongiosa slightly less than half its length. Hind leg with femur cylindrical, not at all thickened, tibia with brush of seta, denser at apex.

Abdomen: Dorsally elongate oval, sternum weakly carinate in midline ( Fig. 26C ), smooth with sparse longer hairs in addition to pilosity, sternite VII without extragenital structure. Connexivum with golden pilosity as elsewhere on sternum, abdominal sterna and terga entire. Spiracles situated below connexival suture, about halfway between anterior and posterior margin of each segment. Each spiracle postero-ventrally with indistinct small oval shiny impressed spot, also a smaller and irregularly shaped impressed spot close to anterior margin of each abdomen sternum. These spots present on corresponding segments on dorsum also but are of similar size. Hemelytra slightly exceeding abdomen and narrowly exposing connexivum.

Male genitalia ( Fig. 29 ): Median pygophore process long ( Fig. 29A–C ), curved in caudal view ( Fig. 29B ), apex sharp in caudal view ( Fig. 29B ) but blunt in lateral view ( Fig. 29C ), ventral surface with a longitudinal ridge, without knobs near base ( Fig. 29B&C ). Parameres broad, subtriangular, inner margins slightly curved ( Fig. 29D&E ), apical half of right paramere ( Fig. 29E ) much broader than left paramere ( Fig. 29D ). Phallus ( Fig. 29F–I ) in resting condition with basal plate bridge slightly longer than basal plate ( Fig. 29F ), pedicel slightly curved, almost as long as basal plate ( Fig. 29H&I ). Dorsal phallothecal sclerite curved, apex blunt ( Fig. 29F, H&I ); lateral phallothecal sclerite somewhat rectangle with a small sharp process at basal portion of inner margin ( Fig. 29I ).

Micropterous male and female ( Figs. 27 , 28 )

Differs from macropterous form as follows.

Head, thorax, bases of coxae, abdomen generally black (with bluish tinge conspicuous in female), with yellowish orange as follows: bases of abdominal second and third segments ventrally and dorsally except fuscous narrow median areas, connexiva both dorsally and ventrally (including narrow adjoining areas of sternites), legs, antennae and labium also yellowish, dorsally abdomen appears with three distinct black and yellow connvexival bands on tergites IV–VI. In female, colouration same as male except antennae slightly darker in some individuals. Posterior one third of hind femur vaguely fuscous in some individuals.

Ocellar tubercle and ocelli obsolete, ocelli indistinct and appearing as shiny cuticular areas in female. Head surface above with sparse granules. Thoracic pleural integument with fine granules becoming more distinct and denser towards metapleura. Scutellum greatly modified; lateral carina indistinct, also apical process highly reduced to upwardly directed short fine point. Hemelytral flaps extremely reduced, extending to about 2/3 length of scutellum in male, extending to about one third basal length of scutellum in female. Scutellar area, pronotum and other black areas shiny smooth. Dorsum of abdomen with three small scent gland scars of subequal width on terga III–IV, IV–V and V–VI ( Figs. 27A , 28A ).

Distribution. Australia (Queensland, New South Wales and Australian Capital Territory, and also Victoria ( Cassis & Gross, 1995)).

Notes. Stål (1867) recorded that the sex of the examined specimen of Callisphodrus patricius was female, but the type deposited in the NHRS, matching the original information, is a micropterous male, and we designate this type specimen as the lectotype ( Fig. 27 ), presumably were female syntypes that could not be located during this study.

The lectotype micropterous male of C. patricius , with the data listed under the types examined above was examined during the present study. It matched very well with the macropterous specimens listed above in all major characters including the male genitalia, except of course in the macropterous form of the hemelytra. Therefore, this species has been in the present study synonymised with E. ornatus ( Stål, 1863) . The latter species as is recognised in the present study occurs as both macropterous and micropterous forms in the male, but only as micropterous in the female.
