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

Ecnolagria BORCHMANN, 1915 Ecnolagria BORCHMANN, 1915, p. 49 (in key), 139; — Ecnolagria: BORCHMANN, 1936, p. 19 (in key), 139; ARMSTRONG, 1948, p. 292. Body medium-sized to large, subparallel-sided to broadly oval, rather convex, variable in colour. Dorsal surface clothed with decumbent, semierect or erect pubescence; hairs on pronotum, antennae and legs not conspicuously long. Head and pronotum distinctly punctate. cf.Head with frons strongly convex in front of eyes, forming a transverse V-shaped swelling which is continuously impunctate throughout interantennal space (at least in anterior half). Interocular distance narrower then eye diameter (IOI < 100). — Antennae rather long and not very thick (Fig. 32); segment I clavale and strongly elongate, longer than internatennal distance (IAI >• > 100). Segment II longer than wide, segment III more than 3 times as long as wide at apex, segment XI longer than at least 2 preceding combined, usually much longer. Segments IV to X more or less asymmetrical; triangularly widening toward apices at inner side, inner surface flattened to concave, segment IX (often also X) expanded endoapically, forming a lobiform expansion (less definite on Ecnolagria aeneoviolacea). Segment XI straight, stout, cylindrical to slightly fusiform, apex broadly rounded but a little acuminate toward endoapical angle. — Pronotum a little wider than long, or of the same length and width (80 •< PNI = lOO), widest at or just anterior to middle, weakly constricted before base, surface mostly with traces of four impressions. — Metasternum with a bilaterally compressed median blunt to acute protrusion (absent from Ecnolagria tomentosa and E. monteithi). Abdominal sterna I and II with mesal outgrowths (absent from the two species mentioned above). Last abdominal segment broadly rounded to slightly emarginate posteriorly. — Legs rather strong; femora more or less clavate; tibiae gradually to abruptly widening toward apex, inner edge with a denticulation characteristic for the species (figs 40-54). Latter may consist of denticles subequal in length, or a long, conspicuous tooth and a row of smaller denticles. — Aedeagus strong, heavily sclerotized, shape characteristic for the species, apex mostly acute, rarely blunt (Ecnolagria aeneoviolacea ) (Figs 55-68). Apical piece with 2 keels and an impression between them on dorsal surface. Pleurite IX enlarged, rather strongly chitinized, with a tooth-like projection fitting in the lateral groove of aedeagus and with dilated apex surrounding the tip of the apex of aedeagus (Fig. 55). $. Similar to males. Frons without conspicuous interantennal swelling. Interocular distance nearly as wide as or wider than eye diameter (90 < 101 •< 130). Antennae (Fig. 33) with segment I less elongate, longer than half of interantennal distance but shorter than whole distance (50 < IAI < 80). Segment XI always shorter than 3 preceding combined. Segments IV to X simple, not asymmetrical. Pronotum more transverse (70 < PNI < 85). Surface of mesosternum and abdominal sterna even. Last abdominal segment acutely rounded posteriorly. Type species: Lagria grandis GYLLENHAL, 1817, by subsequent designation (BORCHMANN 1936, p. 139). Remarks — Ecnolagria is a true Australian genus with 8 species. BORCHMANN (1936) added 2 more species from Sulawesi and established a new subgenus (Onocera) for them, but these are definitely not congeneric with the Australian species. KEY TO SPECIES OF ECNOLAGRIA 1 (2) Elytra metallic green, interspaces rugosely plicate, coriaceous. A species restricted to Western Australia E. aeneoviolacea (CHAMPION, 1895) 2 (1) Elytra not metallic green (although sometimes greenish), interspaces much more weakly plicate. Species never occurring in Western Australia. 3 (6) Size large, elytra dark greenish, with slight purpureo-violaceous to bronze tinge. Species restricted to northern Queensland. 4 (5) Ventral surface and femoral base reddish. Male front tibiae with a large median tooth and a row of smaller denticles at the inner side (Fig. 40) E. schneiderae sp. n.
