Horaeomorphus eucalypti Franz, 1975: 145: 123  .

Type material studied. Holotype: AUSTRALIA: ♂: six labels ( Fig. 165View FIGURES 160 – 167): "Umg. [i.e., env.] Brisbane / Queensld., Austr. / lg. H. Franz 1970 " [white, printed], " Horaeomorphus  / eucalypti  m. / det. H. Franz" [white, handwritten and printed], " Typus " [red, handwritten], "male symbol" [white, printed], " SAMAAbout SAMA Database / No. 25 - 037015" [white, printed], " SCIACHAROIDES  / eucalypti ( Franz, 1975)  / det. P. Jałoszyński, 2014 " [white, printed] ( SAMAbout SAM).

Revised diagnosis. Male: BL 1.45 mm; pronotum with antebasal transverse groove interrupted in middle and with distinct internal pair of pits; mesanepisterna without setal brushes; subtriangular apical region of aedeagus in ventral view laterally confluent with basal capsule. Female and its diagnostic characters unknown.

Redescription. Body of male ( Fig. 161View FIGURES 160 – 167) strongly convex, elongate but relatively stout, with long appendages, BL 1.45 mm; cuticle glossy, body uniformly light brown with slightly lighter appendages, vestiture yellowish.

Head ( Fig. 161View FIGURES 160 – 167) in dorsal view rounded, broadest at eyes, HL 0.25 mm, HW 0.30 mm; tempora slightly longer than eyes, strongly curved posteromesally; vertex weakly convex; frons subtrapezoidal. Eyes moderately large and moderately projecting laterally from the head silhouette, finely faceted. Punctures on head dorsum fine and sparse, inconspicuous; setae short, on frons and anterior part of vertex sparse and suberect, tempora and posterior margin of vertex with dense bristles directed posteriorly and slightly posterolaterally. Antennae ( Fig. 161View FIGURES 160 – 167) slender, with five terminal antennomeres forming indistinct club, AnL 0.68 mm; antennomeres I–II distinctly elongate, III–VI each only slightly longer than broad, VII–X distinctly transverse, XI only slightly longer than X, 1.2 x as long as broad, with blunt apex.

Pronotum ( Fig. 161View FIGURES 160 – 167) indistinctly elongate, broadest between middle and anterior third, PL 0.38 mm, PW 0.33 mm; anterior and lateral margins rounded; posterior margin shallowly bisinuate; base of pronotum with shallow and narrow transverse groove interrupted in middle, and with two pairs of pits: larger internal pair and smaller external pair. Punctures on pronotal disc fine and inconspicuous; setae sparse, thin, short and suberect, sides of pronotum with moderately dense bristles.

Elytra ( Fig. 161View FIGURES 160 – 167) oval, broadest distinctly anterior to middle, EL 0.83 mm, EW 0.60 mm, EI 1.38; basal impressions short but distinct; elytral apices separately rounded. Punctures on elytral disc much more distinct than those on pronotum, in anterior median area separated by spaces comparable to diameters of punctures, on sides and posteriorly punctures reducing in diameter and depth; setae much longer than those on head and pronotum, moderately dense, curved and erect. Hind wings well developed, about twice as long as elytra.

Legs ( Fig. 161View FIGURES 160 – 167) long and slender, without modifications.

Aedeagus ( Fig. 171View FIGURES 168 – 173) relatively stout, AeL 0.25 mm, in ventral view drop-shaped with strongly narrowing subtriangular apical region laterally confluent with sides of median lobe; internal armature composed of H-shaped subapical structure proximally connected to two lateral bunches of thin hair-like sclerites; parameres slender, each with three apical setae.

Female. Unknown.

Distribution ( Fig. 197View FIGURES 193 – 198 b). South-eastern Australia: Queensland.

Remarks. This species looks like a miniature Sciacharoides thompsoni  ; s ee Remarks section at the latter species above.
