( Figs. 63 –64, 66 View FIGURES 62 – 66 , 68 –69, 72– 73 View FIGURES 67 – 73 )

Stenichnus (Austrostenichnus) kuschelianus Franz, 1977: 19   , Fig. 4 View FIGURES 1 – 4 .

Type material studied. Holotype: 3: seven labels ( Fig. 66 View FIGURES 62 – 66 ): " NEW ZEALAND AK / Tropicana Drive / Lynfield / 16.8. 1975 / G. Kuschel" [white, printed and handwritten in black], 'Gahnia / procera" [white, handwritten in black], " Stenichnus   / ( Austrostenichnus   ) / kuscheli [sic!] m. / det.H.Franz" [white, printed and handwritten in faded black]; " Type " 'red, handwritten in faded blue]; " Stenichnus   / kuschelianus   / Franz / det. G. Kuschel / 1980 " [white, printed and handwritten in black]; "Entomology / Division / D.S.I.R. / New Zealand " [golden, printed]; and a printed registration label with code NZAC 04061242 (NZAC).

Diagnosis. Antennae massive, gradually thickened distally ( Fig. 63 View FIGURES 62 – 66 ); aedeagus ( Figs. 72–73 View FIGURES 67 – 73 ) stout with short lateral groups of needle-like internal sclerites.

Redescription. Body of male ( Fig. 63 View FIGURES 62 – 66 ) strongly convex, elongate and slender, with long appendages, BL 1.80 mm; glossy, uniformly reddish-brown with slightly lighter appendages; vestiture yellowish.

Head ( Figs. 63 View FIGURES 62 – 66 , 69 View FIGURES 67 – 73 ) approximately subtriangular, broadest at eyes, HL 0.33 mm, HW 0.33 mm; tempora much shorter than eyes; vertex distinctly transverse and weakly, evenly convex, anteriorly confluent with frons; frons convex, just behind barely marked supraantennal tubercles with a pair of shallow circular impressions; eyes large and strongly convex, strongly oval 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. 63 View FIGURES 62 – 66 ) robust, gradually thickened distally, AnL 0.95 mm; antennomeres I–III strongly elongate, IV as long as broad, V–VI slightly longer than broad, VII–X each slightly transverse, XI 1.5 × as long as broad.

Pronotum ( Fig. 63 View FIGURES 62 – 66 ) in dorsal view with large and subtriangular discal part broadest near anterior fourth of PL and short posterior collar demarcated by distinct lateral constriction, PL 0.48 mm, PW 0.39 mm; anterior and lateral margins of discal part confluent and rounded; posterior margin arcuate; hind pronotal corners indistinctly marked, blunt and obtuse; posterior collar dorsally indistinctly demarcated by shallow, narrow and arcuate transverse groove with deepened lateral parts running on pronotal sides and connecting very small and indistinct lateral ante-basal foveae located on sides of pronotum, groove extends at each end beyond lateral foveae nearly to adcoxal part of hypomeron; posterior collar in middle bearing indistinct and short median longitudinal ante-basal groove. Punctures on pronotal disc very fine and inconspicuous; setae long, sparse and recumbent to suberect.

Elytra ( Fig. 63 View FIGURES 62 – 66 ) oval and more convex than pronotum, broadest between middle and anterior third, EL 1.00 mm, EW 0.70 mm, EI 1.43; humeral calli distinct, developed as elongate protuberances; elytral apices separately rounded. Punctures on elytral disc more distinct than those on pronotum but shallow and sparse; setae moderately long, sparse and suberect. Hind wings well-developed, twice as long as elytra.

Legs ( Fig. 63 View FIGURES 62 – 66 ) long and slender; all tibiae straight or nearly straight.

Aedeagus ( Figs. 72–73 View FIGURES 67 – 73 ) stout, AeL 0.38 mm, median lobe subtrapezoidal, with abruptly and strongly narrowed apical part of dorsal wall forming long subtriangular projection; internal armature complicated, composed of submedially located central complex and sub-apical lateral groups of short needle-like sclerites projecting distally from median lobe; parameres slender, each with two long apical setae.

Female. Unknown.

Distribution. New Zealand: North Island.
