Sauvagesinella Paulian  

Type species. Sauvagesinella monstrosa Paulian, 1934   .

Diagnosis. Medium to large, total length 2.5–5.5 mm. Elytra with 8 striae, 7 on disc one on the edge of epipleura ( Fig. 11 View FIGURE 11 A). Dorsal parts of eyes slit shaped, narrowing basally, 3–5 facets wide, with raised inner edge. Head without basal carina. Antennae with 3-antennomere black club with club antennomeres approximately equal width. Mesepimera impunctate. Meso-metaventral suture nearly straight. Metaventral lobe narrowly bordered beside mesocoxae. Protibiae of males expanded at inner apical angle and bearing narrow comb of short, flattened bristles and brush of long setae directed perpendicularly ( Fig. 11 View FIGURE 11 C–D). Protibiae with 3 teeth on outer edge, each tooth with a single group of setae dorsally; dorsal carina from 3rd tooth extending to base, exposing large lateral basal area when viewed from above ( Fig. 11 View FIGURE 11 C). Profemora with a flattened posterior face. Trochantofemoral anterior pit absent ( Fig. 11 View FIGURE 11 B). Mesocoxae strongly oblique, mesotibiae of male with a small brush of setae at inner apical angle. Protarsi with 5 tarsomeres, tarsomere 5 the longest. Mesotarsi and metatarsi with tarsomere 5 longest and equal to tarsomere 3–4 combined. Metafemora with flattened, reticulate posterior face bearing 1, 2, or 3 carinae. Tarsal claws distinctly toothed, moderate to large ( Fig. 11 View FIGURE 11 E). Pygidium simple, without grooves or depression. Abdominal ventrite 6 shorter that ventrites 2–5 combined. Hind wings fully developed, reduced, or absent. Aedeagus with 2 types: those of S. becki   and S. monstrosa   (apical expansion of right paramere large), or those of S. palustris   and S. loftyensis   (apical expansion of right paramere small) (see Fig. 12 View FIGURE 12 ).

Distribution. Southern Western Australia from south of Perth to Cheynes Beach in areas of more than 750 mm annual rainfall, in jarrah and paperbark swamps ( Matthews 1974). Also in southeastern South Australian in the Mount Lofty Block environmental province, which extends from Kangaroo Island to Mount Remarkable.
