Key to the species of Neobuprestis 1 Lateral carina of pronotum confined to basal half; punctation between elytral costae not arranged in longitudinal series; scutellum1.5–2.0 times as wide as long; sexually dimorphic: male with expanded segments of antenna relatively larger, expanded segments almost completely covered with basiconic sensillae, lacking obvious sensory foveae (Fig. 18); elytra yellow, sometimes with a slight purple tinge towards the lateral margin (Fig. 1); last ventrite with apex broadly and deeply excised, with a slightly developed flange and well developed lateral spines (Fig. 21); female with serrate segments of antennae relatively smaller, with fields of B 4 c sensillae confined to the inner margin, with apical sensory foveae; elytra usually purple but sometimes yellow-brown with only a slight purple tinge (Fig. 2); last ventrite with apex truncate sometimes with a small shallow excision at middle; N.W. Victoria, South Australia & W. Australia.............. N. (s. str.) peroni (Gory & Laporte) - Lateral carina of pronotum almost extending to the notosternal suture (Figs. 5, 6); punctation between elytral costae partly arranged in longitudinal series next to the costae; scutellum about as wide as long; male and female not sexually dimorphic (no male of N. frenchi has been seen); mountains of S.E. Victoria & New South Wales N. (Balthasarella) spp................ 2 2 Hind coxal plate abruptly narrowing about one-third the distance from the inner margin (as in Fig. 31); lateral carina of pronotum slightly curved downwards distally when viewed from the side (Fig. 6)...................... N. (B.) williamsi sp. n. - Hind coxal plate gradually narrowing from the coxal insertion (as in Fig. 30); lateral carina of pronotum straight or slightly curved upwards distally when viewed from the side (Fig. 5)...............................
