( Figs 1, 2 View FIGURES 1 – 6 )
Material examined. Holotype male, Queensland, Kuranda (Top of the Range), 16°48’S 145°38’E (335 m), 19 Butler Drive, 4 Nov 2009, sweep net, A. Wells. Paratypes, Queensland: 15 males, same data as for holotype.
Diagnosis. This species has distinctive males with a pair of small rectangular processes apicolaterally on sternite VIII and a pad of tiny jet black warts apicomesally on lateral lobes of segment IX.
Description. Adults: Forewing length, male 1.3-1.5 mm; female 1.4 mm. Antennae 17-segmented. Male genitalia ( Figs 1, 2 View FIGURES 1 – 6 ): Abdominal sternite VIII deeper than wide, in ventral view with 2 small widely separated processes apically, in lateral view apically acute. Segment IX produced laterally, in ventral view appearing as stout lobes turned inwards at tips and each bearing numerous small dark rugosities in apical pad; in lateral view broadly truncate apically. Tergite X (= dorsal plate) parallel-sided, truncate apically. Inferior appendages triangular; ventral plate bifid, forming 2 lobes, each bearing apical and subapical seta; elongate triangular in lateral view. Aedeagus elongate, constricted at about 2/3rds length, apparently lacking titillator usually found in this genus.
Remarks. In general form this species resembles O. desleyae sp. nov., and, in having pads of tiny jet black warts on the male genitalic structures, O. justini Wells and O. regia Wells ; in O. desleyae these warts are on produced lateral lobes of tergite IX. Two females collected with the males are associated tentatively with O. barbarae . Unlike females of some congeners (e.g. O. regia Wells and O. papillata Wells: Wells 1980 ), these females have no distinctive ventral glands on abdominal sternite VIII.
Distribution. Known only from the type locality in the Wet Tropics of northeastern Queensland.
Etymology. Named for Barbara Foster Rentz, on whose property this species was collected.
