Diagnosis.

Australosagola minsangi sp. nov. can be easily distinguished from other species by the short and strongly transverse antennomeres (Fig. 6 A, B, G View Figure 6 ), as well as antennomere 1 of both sexes having a pit on the dorsal surface (Fig. 6 C, D, H View Figure 6 , black arrows).

Male description.

Length 2.8–3.5 mm. Head. In dorsal view with concavity at base of frontal rostrum around frontal fovea. Rostrum broad and anterolaterally angulate (Fig. 6 C View Figure 6 ). Antennomere 1 stout, subquadrate, and slightly longer than wide, slightly curved medially, with dorsal preapical fovea (Fig. 6 A, G, H View Figure 6 ); 2 slightly longer than wide and subconical; 3 smallest, forming distinct disc and transverse; 4–10 subquadrate and transverse (Fig. 6 A, G View Figure 6 ). Thorax. Prothorax slightly broader than long, widest at midpoint (Fig. 6 I View Figure 6 ). 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. Hind wings fully developed. Metatrochanter angulate on ventral margin (Fig. 6 E, J View Figure 6 ). Abdomen. Abdominal sternites 4 and 5 (VI – VII) medially impressed (Fig. 6 E View Figure 6 ), 5 (VII) with lateral preapical and apical rows of thick setae near middle (Fig. 6 E, K View Figure 6 ). Genitalia. Length 0.46 mm, aedeagus symmetrical, pair of elongate projections at midpoint of median lobe widening to apices, longer than parameres, apices bluntly rounded (Fig. 6 L – N View Figure 6 ). Apex of median lobe with small median spine visible in ventral and basoventral views (Fig. 6 L, M View Figure 6 , black arrows). In lateral view, projections at base of median lobe strongly curved (Fig. 6 N View Figure 6 ), appearing broadly V-shaped in basolateral view and directed apically from basal margin of median lobe, lateral margins of median lobe spinose at middle in ventral view, phallobase margins bluntly rounded at middle in ventral view, in lateral view flat and shortly curved (Fig. 6 L – N View Figure 6 ).

Female sexual characters.

Metatrochanter with posterior margin convex (Fig. 6 F View Figure 6 ). Abdominal sternites 4–5 (VI – VII) convex, lacking thick setae at apex of abdominal sternite 5 (VII; Fig. 6 F View Figure 6 ).

Etymology.

This species is named for a biological control specialist who has been an enthusiastic supporter of this study, Min-Sang Jang.

Distribution.

New South Wales (Fig. 13 View Figure 13 , black squares).

Habitat.

Specimens of this species were collected using flight intercept traps (F. I. T.), by sifting leaf or rotten woods in old and cut dry and wet sclerophyll Eucalyptus forests and in old warm-temperate rainforests.
