Orthorhinoides dugdalei
n. sp.
Figs 93, 165, 166
DESCRIPTION. — Integument reddish brown, darker obliquely outwards and apicad on interstriae 2-5 on middle of elytra; scaling yellow or yellowish brown, denser on sides of pronotum, humeral callus and a line on elytra extending from slightly before middle obliquely backwards to interstria 7, then running to apex after joining a similar line coming from interstria 3; apical area of elytra enclosed by outer line darker owing to sparser and finer vestiture.
Head convex in front, punctate, squamose, lacking granules. Rostrum long, thin, nearly 1.3 x longer than prothorax, rather strongly rounded on sides, densely punctate at basal one-third, gradually, gradually more finely punctate apicad, squamose only at base, especially against eyes; prorostrum nearly twice as long as wide at apex. Prothorax 1.13 x broader than long, granulose-rugose, moderately convex, granules with an elongate scale or squamiform seta. Scutellum densely squamose.
Elytra with well defined striae, strial puncta pupillated with a scale except on darker apical area; granules obsolete or obsolescent, a few small, more distinct granules on interstria 3 near base. Abdomen not impressed at base, pubescence appressed. Fore coxae contiguous. Fore femora distinctly longer than middle ones; hind femora extending to about end of abdomen. Fore tibiae short, robust, well short of trochanter when folded, curved, slightly asperate on lower edge at apical one-third. Fore tarsi lacking fringe of long hairs, segment 2 symmetrical, triangular, not distinctly longer than 3.
Male: tegmen rather similar to that of
Dracophyllius dracophylli
(Fig. 164). Aedeagus [in rather teneral condition] as in Figs 165, 166; body 0.825 x
0.237 mm
; apodeme
1.250 mm
, half as long again as body; internal sac with a
1.20 mm
long basal sclerite, a small, more or less X-shaped steering plate, no other sclerites or rods apparent in the teneral specimen.
Length:
5.8 mm

HOSTPLANTS. —
Dracophyllum
cf

(
Epacridaceae
).
ETYMOLOGY. — The species is named after the lepidopterist J S Dugdale, Landcare Research, who found a dead terminal rosette of the hostplant still containing a weevil larva and rearing it through.
REMARKS. — The vivid reddish brown colour of
O. dugdalei
is unique to this species of the genus.
