(Figs. 63–64, 66, 68–69, 72–73)
Stenichnus (Austrostenichnus) kuschelianus Franz, 1977: 19, Fig. 4.
Type material studied. Holotype: 3: seven labels (Fig. 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); aedeagus (Figs. 72–73) stout with short lateral groups of needle-like internal sclerites.
Redescription. Body of male (Fig. 63) 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, 69) 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) 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) 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) 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) long and slender; all tibiae straight or nearly straight.
Aedeagus (Figs. 72–73) 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.
