Scydmaenilla (Scydmaenilla) queenslandica Franz View in CoL
( Figs. 94 View FIGURES 93 – 98 , 100 View FIGURES 99 – 104 , 106 View FIGURES 105 – 110 , 114–115 View FIGURES 111 – 115 )
Stenichnus (Scydmaenilla) queenslandicus Franz, 1975: 139 , Fig. 115 View FIGURES 111 – 115 .
Type material studied. Holotype: 3: three labels ( Fig. 106 View FIGURES 105 – 110 ): "Umg. Maipoton / Queensld., Austr. / lg.H.Franz 1970" and "Pa 77" on the reverse side [white, printed, reverse handwritten in blue], " Stenichnus / queenslandicus / m. / det.H.Franz" [white, printed and handwritten in blue], " Typus " [red, handwritten in blue] (SAM).
Diagnosis. Body length about 1.20 mm; elytra stout, EI 1.44; antennal club with slightly asymmetrical antennomere X; metatibiae with short and slender subapical setal brushes; lateral metaventral carinae absent; short median longitudinal groove on posterior pronotal collar present; lateral marginal pronotal carinae barely discernible.
Redescription. Body of male ( Figs. 94 View FIGURES 93 – 98 , 100 View FIGURES 99 – 104 ) slightly flattened, elongate but moderately slender, with long appendages, BL 1.18 mm; glossy, uniformly brown with slightly lighter legs and maxillary palps; vestiture yellowish-brown.
Head ( Fig. 94 View FIGURES 93 – 98 ) approximately subtriangular, broadest at eyes, HL 0.20 mm, HW 0.25 mm; tempora distinctly shorter than eyes; vertex transverse and distinctly, evenly convex, anteriorly demarcated from frons by a pair of large but superficial impressions broadly separated in middle and located postero-mesally to distinct but weakly raised supraantennal tubercles; frons between antennal insertions convex; eyes large and strongly convex, distinctly bean-shaped and oblique in relation to the long axis of the head. Punctures on head dorsum fine and sparse, inconspicuous; setae short, sparse, suberect. Antennae ( Fig. 94 View FIGURES 93 – 98 ) relatively short, with distinct club composed of antennomeres IX–XI, with slightly asymmetrical antennomere X, AnL 0.45 mm; antennomeres I–II strongly elongate, III–V each about as long as broad, VI–VIII slightly transverse, IX–X strongly transverse, XI 1.4 × as long as broad.
Pronotum ( Fig. 94 View FIGURES 93 – 98 ) in dorsal view with large and oval discal part broadest near anterior fourth of PL and short posterior collar demarcated by barely marked lateral constriction, PL 0.33 mm, PW 0.28 mm; anterior and lateral margins of discal part confluent and rounded; posterior margin nearly straight; hind pronotal corners indistinctly marked, blunt and obtuse; posterior collar dorsally distinctly demarcated by sharply marked, narrow and slightly arcuate transverse groove connecting a pair of small but deep lateral ante-basal foveae; additionally posterior collar with short but distinct median longitudinal groove connected to ante-basal transverse groove but not reaching posterior pronotal margin; lateral marginal carinae barely discernible. Punctures on pronotal disc very fine and inconspicuous, those on posterior collar distinct and dense, but only superficial; setae moderately long, sparse and suberect to erect.
Elytra ( Fig. 94 View FIGURES 93 – 98 ) oval and more convex than pronotum, broadest near anterior third, EL 0.65 mm, EW 0.45 mm, EI 1.44; humeral calli moderately distinct, developed as elongate protuberances; elytral apices separately rounded. Punctures on elytral disc much more distinct than those on pronotum, shallow and with diffused margins but relatively large and separated by spaces equal to or slightly smaller than puncture diameters; setae moderately long, relatively dense and suberect. Hind wings well-developed, twice as long as elytra.
Legs ( Fig. 94 View FIGURES 93 – 98 ) long and slender; all tibiae straight or nearly straight, each metatibia with short and slender subapical setal brush.
Aedeagus ( Figs. 114–115 View FIGURES 111 – 115 ) relatively stout, approximately oval, AeL 0.11 mm, with trapezoidal and welldemarcated but short apical part; internal armature lightly sclerotized, with sub-basal central complex and submedian lateral groups of fine needle-like sclerites; parameres short and robust, each with one apical and two subapical setae.
Female. Unknown.
Distribution. Eastern Australia: southeastern Queensland.
Remarks. Scydmaenilla queenslandica , S. thompsoniana and S. constricta are unique within the genus in having the asymmetrical antennomere IX; see Remarks for S. constricta and S. thompsoniana .
