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

4 (7) Antennái segment I of both sexes much shorter than half of inerantennal distance (IAI < 50). Antennái segments with hairs much shorter than length of segments. Size smaller 5 (6) Antennae thick and short, segment III not longer than segment I, segment II not longer than wide. (Fig. 4) Elytra subparallel-sided, barely dilated posteriorly on both sexes; humeral angle pronounced Xenolagria gen. n. 6 (5) Antennae slenderer and longer, segment III usually longer than segment I, segment II longer than wide (Figs 7-16). Elytra distinctly dilated posteriorly at least on females; humeral angle not conspicuous Lagria FABRICIUS, 1775 7 (4) Antennái segment I of males considerably, of females slightly longer than half of interantennal distance (50 < IAI < 100). Antennái segments (at least basal 4) with hairs as long as or longer than length of segments. Size larger Metriolagria gen. n. 8 (3) Antennae of males with segments IX or IX and X more or less expanded at inner side. 9 (10) Antennae of males with segment I strongly elongate, longer than interantennal distance (IAI > 100), that of females longer than half of interantennal distance (50 < IAI < 100). Male pronotum slightly transverse, sometimes as long as wide, but broader than head. Size larger, body robust, legs strong Ecnolagria BORCHMANN, 1915 10 (9) Antennae of males with segment I less elongate, longer than half of interantennal distance (50 < IAT < 100), that of females shorter (IAI < 50). Male pronotum at least as long as wide, usually longer, narrower than head. Size smaller, body slender, legs gracile Stenolagria gen. n. Acerogria BORCHMANN, 1936 Acerogria BORCHMANN, 1936, p. 19 (in key), 137. —Birolagria Pic, 1956, p. 86, syn. n. Body medium-sized to large, elongate oval, moderately convex, elytra yellowish, the rest of body black. Dorsal surface clothed with short, semierect pubescence. Head sparsely punctate, pronotum impunctate, uneven. cf.Head with a less developed smooth interantennal swelling. Eyes small, interocular distance more than 1.5 times as broad as eye diameter (IOI =- 150). — Antennae thick and long; segment I slightly swollen, a little longer than half of interantennal distance (50 < IAI -= 60); segment II a little longer than broad, segment III longer than broad, segments IV to VI quadrate to slightly transverse, segment VII flattened and triangularly dilated at inner side, segment VIII quadrate, segment IX lobiformly expanded at inner side, segment X subquadrate, segment XI fairly bent, flattened at inner side, much longer than 6 preceding segments combined (Fig. 1). — Pronotum transverse (PNI < 100), broader than head, with distinct impressions, widest at base, sides slightly converging toward anterior margin. — Elytra elongate, very weakly dilated posteriorly, apex simply rounded, epipleura ending before apex. — Surface of mesosternum and abdominal sterna even, very finely punctate. Last abdominal segment with apex slightly excavate. — Legs moderately long, femora and tibiae edged at outer margin. — Aedeagus long and slender, apex acute (Figs. 2-3). 9. Much broader. Head without interantennal swelling. Interocular distance more than twice as broad as eye diameter (IOI >• 200). Antenna! segment I shorter than half of interantennal distance (IAI -= 50). Segments VII and IX simple. Segment XI short and stout, a little longer than 2 preceding combined. Last abdominal segment with apex rounded. Type species : Of Acerogria, Ccrogria dohrni BORCHMANN, 1910 (described from Philippines), by subsequent designation (BORCHMANN 1936, p. 138). Of Birolagria, Birolagria cicatricosa Pic, 1956 (described from New Guinea), by monotypy.
