Cephennomicrus indistinctus View in CoL sp. n.
( Figs 64–68 View FIGURES 64–73 , 123 View FIGURE 123 )
Type material. Holotype: AUSTRALIA (QUEENSLAND): ♂, three labels: " 11.51S 142.38E QLD / 12 km SSE GoogleMaps
Heathlands / 2-22 Mar. 1992 / P. Feehney FIT #2" [white, printed], "F.I.T. / ANIC 1242 / closed forest" [white, printed], " CEPHENNOMICRUS / indistinctus m. / P. Jałoszyński, '18 / HOLOTYPUS " [red, printed] ( ANIC). Paratype: 1 ♂, same data except for 26 Jan.–1 Mar. 1992, "Malaise #3#4" ( ANIC).
Diagnosis. BL 0.80–0.85 mm; body stout, EI 1.06–1.09; antennomeres III–IX each as long as broad; antennal club dimerous, sharply delimited and strongly flattened; inner pair of pronotal antebasal pits not connected; frons and vertex in males unmodified; aedeagus moderately elongate, in ventral view median lobe shallowly and broadly constricted in submedian region, endophallus simple, containing two lateral bunches of needle-like sclerites, subapical region of dorsal wall with paired setae.
Description. Body of male ( Fig. 64 View FIGURES 64–73 ) stout, uniformly reddish brown; setae on head, pronotum and elytra very short, dense and recumbent, but discernible at magnification 40 ×. BL 0.80–0.85 mm.
Head broadest at large, strongly convex and coarsely faceted eyes, HL 0.08 mm, HW 0.23–0.24 mm; vertex and frons unmodified, confluent, weakly and evenly convex; supraantennal tubercles weakly elevated. Punctures fine and inconspicuous. Antennae short, with sharply delimited dimerous and strongly flattened club, AnL 0.33– 0.35 mm, antennomeres I–II distinctly elongate, III–IX each as long as broad, X distinctly transverse, XI about as long as broad.
Pronotum subtrapezoidal, broadest near anterior fourth; PL 0.28–0.30 mm, PW 0.38 mm; anterior margin arcuate, posterior margin nearly straight, anterior corners broadly rounded, sides strongly rounded in anterior third and nearly straight in posterior half, posterior corners strongly obtuse-angled and blunt; base with two lateral pairs of small but distinct pits, transverse groove absent; lateral pronotal carinae indistinctly serrate. Punctures on pronotal disc fine, inconspicuous.
Elytra oval, broadest distinctly anterior to middle; EL 0.45–0.48 mm, EW 0.43–0.44 mm, EI 1.06–1.09; humeral calli distinct; apices separately rounded. Punctures similar to those on pronotal disc.
Legs moderately long and slender, unmodified.
Aedeagus ( Figs 65–68 View FIGURES 64–73 ) moderately elongate; AeL 0.20 mm; median lobe in ventral view subtrapezoidal, endophallus moderately complicated, with two lateral bunches of long, needle-like sclerites; dorsal wall with paired setae in subapical region; each paramere with one apical and two subapical setae of equal length.
Female. Unknown.
Distribution ( Fig. 123 View FIGURE 123 ). Queensland.
Etymology. The name indistinctus refers to the unremarkable body form, which makes this species difficult to identify.
Remarks. Examination of the aedeagus is necessary to identify this species; the constricted median lobe in combination with only one pair of lateral bunches of endophallic needle-like sclerites is unique for C. indistinctus .
