Revised diagnosis. Male and female: body uniformly brown. Male: aedeagus stout, in ventral view with distinctly emarginate apex.

Redescription. Body of male ( Fig. 73View FIGURES 72 – 79) strongly convex, elongate and slender, with long appendages, BL 2.80–2.95 mm (mean 2.87 mm); cuticle glossy, uniformly dark brown with slightly reddish hue, vestiture reddishbrown.

Head ( Fig. 73View FIGURES 72 – 79) broadest at eyes, HL 0.48–0.50 mm (mean 0.50 mm), HW 0.55–0.60 mm (mean 0.58 mm); tempora longer than eyes, strongly curved posteromesally; vertex weakly convex; frons subtrapezoidal. Eyes large and strongly projecting laterally from the head silhouette, finely faceted. Punctures on head dorsum fine, separated by spaces 1.5– 2 x as wide as diameters of punctures; setae on frons and anterior portion of vertex short, sparse and suberect, tempora and posterior portion of vertex densely covered with long bristles directed posteriorly and posterolaterally. Antennae ( Fig. 73View FIGURES 72 – 79) slender, AnL 1.75–1.90 mm (mean 1.83 mm); all antennomeres distinctly elongate, XI slightly shorter than IX –X together, 2.5 x as long as broad, pointed.

Pronotum ( Fig. 73View FIGURES 72 – 79) in dorsal view strongly elongate, broadest near anterior third, PL 0.78–0.85 mm, (mean 0.80 mm), PW 0.58–0.63 mm (mean 0.60 mm); anterior and lateral margins in anterior half rounded; sides slightly concave in posterior third; posterior margin distinctly bisinuate; base of pronotum with two pairs of large and deep pits, additionally with a pair of shallow but distinct impressions located dorsolaterally. Punctures on pronotal disc fine and inconspicuous; entire dorsal and lateral surface of pronotum covered with moderately dense bristles, dorsally with admixture of thin setae.

Elytra ( Fig. 73View FIGURES 72 – 79) slightly rhomboidal, broadest in or slightly behind middle, EL 1.50–1.63 mm (mean 1.57 mm), EW 1.13–1.23 mm (mean 1.17 mm), EI 1.30–1.40 (mean 1.35); basal impressions short but distinct; elytral apices separately rounded. Punctures on elytral disc fine but slightly more distinct than those on pronotum, separated by spaces 2– 3 x as wide as diameters of punctures; setae long, curved, sparse and erect. Hind wings well developed, about twice as long as elytra.

Legs ( Fig. 73View FIGURES 72 – 79) long and slender, without modifications.

Aedeagus ( Figs. 83 –84View FIGURES 80 – 88, 91– 92View FIGURES 89 – 96) elongate but relatively stout; AeL 0.53 mm; in ventral view apex not demarcated, with distinctly emarginate apical margin; internal armature complicated, with submedian complex of elongate and darkly sclerotized structures and subapical finely denticulate lateral lobes of internal sac; parameres long and slender, apices barely noticeably broadened.

Female. Similar to male, on average slightly larger, but body lengths and proportions of body parts overlap with those measured in males, distinguished by antennomere VIII about as long as broad and antennomeres IX –X slightly transverse. BL 2.85–3.05 mm (mean 2.95 mm); HL 0.48–0.50 mm (mean 0.50 mm), HW 0.58–0.60 mm (mean 0.58 mm), AnL 1.58–1.75 mm (mean 1.69 mm); PL 0.78–0.85 mm (mean 0.81 mm), PW 0.58–0.63 mm (mean 0.60 mm); EL 1.55–1.70 mm (mean 1.64 mm), EW 1.13–1.23 mm (mean 1.18 mm), EI 1.38–1.42 (mean 1.39).

Distribution ( Fig. 195View FIGURES 193 – 198 b). South-western Australia: Western Australia.

Remarks. Franz (1975) studied four specimens originally mounted on a single card, on which one male was annotated as "TY" ( Fig. 78View FIGURES 72 – 79). Franz treated this male as a holotype and remaining specimens as paratypes, but studied the aedeagus only in a single remounted " paratype " male ( Franz 1975). In fact, Lea (1910) clearly stated that he collected "numerous specimens obtained under a log on sandy ground in the company of ants", and in his description none of them is treated as a type. Therefore, four specimens preserved at SAM, one at NHM and three at ANIC, all identifiable as coming from the original type series, are syntypes. The male originally mounted together with three other specimens on one card and annotated as "TY" is here designated as lectotype, to provide a name-bearing type for Phagonophana latipennis  . Three more specimens labeled as Phagonophana latipennis  with the same hand but not belonging to the type series (collected in different localities) ( ANIC) belong to other species: two are designated here as the holotype and paratype of Scydmaenozila inexpectata  sp. n. (from the Ferguson Collection), and one is a Syndicus  (from the Ropes Collection).

Scydmaenozila latipennis  is similar to Scydmaenozila mallacootana  sp. n. and Scydmaenozila inexpectata  sp. n.; it clearly differs from these species in the broader elytra in relation to the pronotum (PW/EW 0.48–0.56 vs. 0.60 vs. 0.58–0.61, respectively), and in the structures of the aedeagus.
