Diagnosis.

This species can be distinguished by following characters: antennomeres 4–10 slightly constricted at middle (Fig. 3 A, B, H); slightly opened rostrum (Fig. 3 I); angulate ventral margin of metatrochanter (Fig. 3 E, M); concave abdominal sternites 4 and 5 (VI – VII) in male; distinct setate margin of abdominal sternite 5 (VII) (Fig. 3 F, N).

Male description.

Length. 2.5–2.8 mm. Body reddish-brown. Head. Head in dorsal view with large impression at midpoint of head at area of frontal fovea. Vertexal foveae well-developed (Fig. 3 I). Antennomere 1 cylindrical, longer than wide; 2 subquadrate and as long as wide; 3 smallest, subconical and as long as wide; 4–6 longer than wide and slightly constricted at middle; 7 and 8 as long as wide and slightly constricted at middle; 9 and 10 transverse and slightly constricted at middle (Fig. 3 A, H). Thorax. Prothorax slightly broader than long for both sexes, widest at midpoint (Fig. 3 J). Elytra with two subbasal elytral foveae, three basal elytral foveae (1 being fovea at base of sutural stria), discal elytral foveae with short discal striae, and fovea in sutural striae (Fig. 3 L). Hind wings fully developed (Fig. 3 K). Metatrochanter angulate on ventral margin, distinct in lateral view [Fig. 3 E (black arrow), F, M (black arrow)]. Abdomen. Median part of abdominal sternites 4 and 5 (VI – VII) both largely impressed. Abdominal sternite 5 (VII) with lateral preapical rows and apical row of thick setae on medial apical projection (Fig. 3 F, N). Genitalia. Length 0.37 mm, aedeagus symmetrical, pair of elongate dentate projections near midpoint of median lobe, curved inward at apex in basoventral view (Fig. 3 P, white arrow), slightly narrower in lateral view, hook-shaped projection on basal part of median lobe best visible in lateral view, projection forming short broad U in ventral view, phallobase with lateral margins evenly rounded in basoventral view, flat and strongly curved in lateral view (Fig. 3 O – Q).

Female sexual characters.

Metatrochanter smoothly convex. Abdominal sternites 4 and 5 (VI – VII) broadly convex, lacking thick setae at apex of abdominal sternite 5 (VII) (Fig. 3 G).

Comments.

Australosagola tasmaniae comb. nov. resembles to A. rugicornis comb. nov., and A. minhoi sp. nov., but it can be easily separated from A. rugicornis by the features of the antennomeres, which are greatly constricted at the middle in A. rugicornis (Fig. 4 A, B, G). And it differs from A. minhoi in the size of the eyes, with the minimum width between eyes being ~ 1 / 2 the head width in dorsal view (Fig. 7 C, D, H). Based on the weakly constricted antennomers of the figure of S. rugicornis in Chandler (2001: fig. 32), the specimen illustrated is a specimen of S. tasmaniae . See Oke (1932: 150, fig. 3) for a figure of the antennae, and the figure of S. tasmaniae in Lea (1911: pl. XXI, fig. 1), which both show unmodified antennomeres.

Distribution.

Found in the Australian Capital Territory, Tasmania, and Victoria (Fig. 13, blue circles).

Habitat.

Specimens of this species were collected using flight intercept traps (F. I. T.), yellow pan traps, by spraying pyrethrin on Anthospermum and Nothofagus tree trunks, by sifting leaf litter in Eucalyptus forests, or by use of emergence traps. Found in rainforests and wet sclerophyll forests dominated by Nothofagus cunninghami or Eucalyptus and Acacia species.
