Merkl, O.: A review of the Australian species of the subtribe Lagriina (Coleoptera, Tenebrionidae: Lagriinae)

a little curved, unarmed to denticulate at inner edge. — Aedeagus lightly sclerotized, simpe,l usually not very useful in characterizing the species (Figs 17-24). 9- Similar to male; last antennái segment shorter, interocular distance wider, pronotum more transverse than that of males. Tibiae always unarmed. Type species: Chrysomela hirta LINNAEUS, 1758, by subsequent designation (LATREILLE 1810, p. 428). Remarks — This is a large collective genus with some 150 species described from every continent except the Americas (one species has been introduced to South America from Africa). The group has been used as a dumping-ground for various species which do not have conspicuous characters typical to more restricted genera. Actually, the species are not closely related to one another and revisions may separate more limited groups as new genera. The 8 Australian species currently assigned to Lagria are known to occur in Queensland {southwards to Brisbane) and in the Northern Territory. KEY TO AUSTRALIAN SPECIES OF LAGRIA 1 (2) Elytral pubescence completely decumbent. Last antennái segment of male about as long as 5, that of female as 3 preceding combined (Figs 7-8). Head and pronotum dark metallic green, elytra leaden with shallow green or purplish tinge. Antennae and legs entirely black L. plumbeipennis sp. n. 2 (1) Elytral pubescence semierect to erect, at least in part. Last antennái segment of male always shorter than 4 preceding combined. Antennae and/or legs never entirely black. 3 (4) Eyes conspicuously large; interocular distance of both sexes narrower than eye diameter (IOI < 100). Hind tibiae of males distinctly curved, serrate apically in the inner edge (Fig. 26). Elytral pubescence largely decumbent but mixed with erect hairs L. tenera sp. n. 4 (3) Eyes normal; interocular distance of both sexes broader than eye diameter (IOI > > 100). Hind tibiae of males nearly straight. Elytral pubescence semierect to erect. 5 (6) Head and pronotum pale yellowish red, elytra shining green, with blue tinge basally and golden lustre apically. Hind tibiae of males denticulate in the inner edge. Size small L. ruficeps MACLEAY, 1887 •6 (5) Head and pronotum dark blue, greenish or blackish, elytra blue to blackish, sometimes with light pattern. Size larger. 7 (10) Antennae slender, segment X not transverse. Segments largely yellowish, only last two segments darker (Figs 12-13). 8 (9) Elytra vivid blue. Shape more elongate L. azureipennis MACLEAY, 1886 9 (8) Elytra pichy black with faint bronzy tinge. Shape less elongate L. queenslandica BORCHMANN, 1915 10 (7) Antennae stouter, segment X transverse. At least apical 6 segments blackish (Figs 14-16). 11 (12) Colour contrast between yellow basal and black apical segments of antennae conspicuous (Fig. 14). Elytra unicolourcd blue, sometimes greenish or violaceous L. cyanea MACLEAY, 1872
