Camptodes aff. humeralis ( Brullé, 1842)

( Figs 1, 3, 7–8 , 24–25 , 59 )

Strongylus humeralis Brullé 1842: 66 , pl. 5, fig. 2. Type locality: “la province de Corrientes.”

Diagnosis. Distinguished from other Australian cyllodines by the characters given in the above key.

Description. Length = 4.00–5.80 (4.95 ± 0.42; n = 19) mm. Body oblong and slightly convex: body length/ elytral width = 1.29–1.45 (1.38); greatest depth/elytral width = 0.47–0.61 (0.53). Head, pronotum, scutellar shield and elytra dark reddish-brown to black, anterior portion of each elytron sometimes with large red macula, which may or may not extend from suture to lateral edge; undersurface dark brown to black; elytral epipleura sometimes red. Dorsal vestiture very short and not visible at lower magnifications. Head about as long as wide. Eyes 0.38× as long as head width. Temples 0.44× as long as eye, straight. Vertexal line at sides only. Frontoclypeal suture indistinct (represented by weak transverse concavity). Clypeus 0.53× as long as wide at base, sides subparallel, apex subtruncate. Labrum about 0.26× as long as wide; anterior edge distinctly emarginate. Antennal scape 2.00× as long as wide and 1.54× as long as pedicel; antennomere 3 about 1.57× as long as 4; club about 0.95× as long as antennomeres 3–8 combined and 1.54× as long as wide; terminal antennomere 0.81× as long as wide. Mandible 2.75× as long as wide; strongly, gradually curved towards apex, which is unidentate and acute; incisor edge with blunt tooth and small notch; mola well-developed, but relatively narrow, with a number of transverse ridges; prostheca long, membranous and pubescent, with longer hairs apically; base of mola, ventrally with densely pubescent lobe; dorsal surface of mandible with curved oblique ridge. Apical maxillary palpomere 3× as long as wide, widest at basal third, with narrowly rounded apex. Mentum about 0.5× as long as wide at middle, sides diverging to basal fourth then converging to apex, which is deeply biemarginate forming paired subapical lobes flanking a low rounded lobe. Prementum longer than wide, with sclerotised ligula slightly emarginate at apex; labial palps attached at about middle; apical labial palpomere about 2.22× as long as wide, with broadly rounded apex. Genal ridges slightly converging and extending almost to ends of temples. Pronotum 0.45–0.53 (0.49)× as long as wide, widest near posterior edge and slightly wider than combined elytra; sides obliquely explanate; anterior edge shallowly emarginate, so anterior angles very slightly produced forward and broadly rounded; lateral margins very narrow, but just visible for their entire lengths from above; posterior angles obtuse and rounded; posterior edge evenly curved, without marginal bead; disc moderately, evenly convex; punctation very fine and sparse, the punctures usually separated by more than two diameters; interspaces very finely sculptured with microtubercles sometimes forming irregular lines and producing a dull sheen. Prosternum 0.73× as long as mid length of procoxal cavity, weakly convex; prosternal process 0.50× as wide as mid length of procoxal cavity, not curved behind coxae, slightly expanded subapically with broadly rounded apex and no vertical wall; underside (dorsal surface) of process more of less concave, except for pair of apicolateral condyles fitting into the apices of the postcoxal (hypomeral) processes. Scutellar shield 0.32× as wide as pronotum, broadly angulate at apex. Elytra 0.83–0.93 (0.89)× as long as wide and 1.65–1.92 (1.81)× as long as pronotum; sides more or less parallel to beyond middle with lateral edges visible from above; apices broadly, independently rounded, exposing part of pygidium; lateral edges obliquely explanate, concealing epipleura in lateral view; humeri very weak; subsutural lines extending beyond middle; disc slightly convex, gradually declining laterally, with punctures, not forming distinct rows but rather several, somewhat irregular longitudinal clusters separated by finely impressed, vague lines; interspaces finely sculptured, as on pronotum. Anterior edge of mesoventrite on different plane than metaventrite, but with transversely, triangular, almost vertical posternal rest continuing posteriorly as a distinct, curved carina, which is higher in ventral view than the posterior edge of the mesoventrite or the metaventrite; posterior edge of ventrite broadly emarginate. Mesocoxae separated by 1.07× longest longitudinal diameter of mesocoxal cavity. Metaventrite moderately convex, somewhat flattened at middle and slightly concave posterolaterally; distance between meso- and metacoxal cavities 0.21× greatest width of ventrite; discrimen extending almost to base of anterior process, which is short and broadly rounded; coxal line behind mesocoxal cavity beginning near mesal edge and remaining very close to edge of cavity until lateral fifth, where it curves posteriorly and extends to about middle of metaventrite, producing a relatively small axillary space; posterior edges of mesocoxal cavities not joined by line across anterior process of metaventrite. Metanepisternum about 2.2× as long as wide, with sides subparallel and not converging posteriorly. Metacoxae separated by 1.7× mid length (shortest diameter) of metacoxa. Protibia gradually expanded apically, its outer edge lined with short serrations, each of which is associated with a short, blunt spine; outer apex more or less angulate, with longer spines continued along apical edge; posterior face without oblique spine row. Meso- and metatibia narrow at base, abruptly expanded at basal third, then gradually expanded to apex; outer edge lined with to rows of long spines, which are continued onto apical edge. All basal tarsomeres expanded and lobed, metatarsus less than half as long as metatibia. Abdominal ventrite 1 with postcoxal lines barely extending beyond rim of the cavities; ventrites 2–5 each with transverse carina near anterior end; apex of ventrite 5 slightly biemarginate in male. Tergite VIII (anal sclerite) in male apically truncate. Tegmen ( Fig. 24 ) 1.57× as long as wide, sides subparallel; apex subtruncate with slight median emargination; anterior strut 0.61× as long as body of tegmen with slightly expanded, subtruncate apex. Penis ( Fig. 25 ) 2.56× as long as wide and 1.32× as long as tegmen; sides subparallel and apex subangulate; anterior penile strut 2.07× as long as body of penis. Ovipositor 5.5× as long as wide, widest at base, slightly flattened; paraprocts 1.40× as long as gonocoxites, which are 3.07× as long as their combined widths, widest at base; sides gradually narrowing to basal third, then parallel to apices; gonocoxites slightly separated for most of their lengths, heavily pigmented beyond middle and obliquely truncate at apex; gonocoxites ( Fig. 59 ) terminal, 0.16× as long as coxites, 4.3× as long as wide and parallel-sided.

Distribution. Native to northern Argentina and probably southern Brazil and Uruguay. In Australia distributed from northern NSW to southern QLD, but never in coastal regions (see above under genus).

Biology. Larvae and adults found in rotting stems of Opuntia cacti. Recorded from Opuntia stricta (Haw.) Haw. (as O. inermis ), O. streptacantha Lem. , O. tomentosa Salm. -Dyck. and O. aurantiaca Lind. (as tiger pear).
