Merkl, O.: A review of the Australian species of the subtribe Lagriina (Coleoptera, Tenebrionidae: Lagriinae)
Pat Ck., 11 km N of Archer Crossing via Coen, 28-29. VI. 1975, G. B. Monteith (1, QMBA); Port Douglas, H. Stephen (1, NMVA); Weipa, 15. VI. 1969, C. McCubbin (2, NMVA); id., 12.41 S 141.53 E, 20. X. 1976, E. Holm (1, ANIC); no closer locality (1, BMNH; 1, HNHM); no closer locality, X. 1902, F. P. Dodd (1, BMNH); no closer locality, VI-VII. 1918, R. Veith (1, BMNH). — Northern Territory: Groote Eylandt, N. B. Tindale (2, SAMA); Vicinity Gove Airport, NE Arnhem Land, IX. 1973 (1, HNHM; 1, NMVA). Remarks — The more or less conspicuous elytral pattern, the nearly unicolorous dark antennae and the very densely punctured pronotum of this species readily separate it from Lagria australis and Lagria cyanea, to which it is closely related. Metriolagria gen. n. Body rather large, elongate, subparallel-sided, moderately convex, yellowish to blackish brown. Dorsal surface and legs clothed with shorter semierect pubescence mixed with numerous, much longer, erect hairs. Antennae (at least on basal segments) with very long, conspicuous hairs. Head and pronotum distinctly punctate. cf.Head with less developed smooth interantennal swelling. Interocular distance wider than eye diameter (IOI > 100). — Antennae thick, segment, I swollen, elongate, but shorter than interantennal distance (IAI -~ 100), segment II longer than wide, segment III less than 3 times as long as wide at apex, segment XI much shorter than 3 preceding combined. Segments are simple, without any modification. — Pronotum transverse (PNI < 100), broader than head, sides feebly arcuate. — Elytra elongate, apex simple, epipleura ending before apex. Surface of mesosternum and abdominal sterna even, finely punctate. Last abdominal segment with apex rounded. — Legs rather strong; femora a little clavate; tibiae straight, hardly widening toward apex, inner edge with fine denticulation or unarmed. — Aedeagus (Figs 28-31) heavily sclerotized, apex subacute. Apical piece with 2 keels and an impression between them on dorsal surface. Lateral side with very shallow groove. Pleurite IX not conspicuous. 9. Similar to male; frons without interantennal swelling. Interocular distance wider than that of male. Antennái segment I not elongate, a little longer than half of interantennal distance (IAI >• 50). Pronotum more transverse. Legs with tibiae always unarmed. Type species: Lagria affinis BOISDUVAL, 1835, by present designation. Remarks — This genus is closely related to Ecnolagria. The similar structure of the aedeagus, the general appearance and the common centre of range refer to a possible common ancestor of the two genera. In collections, the specimens often stand under the name of various species of Ecnolagria. However, the long vestiture (particularly on antennae and legs), the much thicker antennae (note that segment III of male Ecnolagria more than 3 times as long as wide at apex), the more plicate elytra and the hardly expressed sexual dimorphism clearly separate Metriolagria. The new genus is proposed for 2 species; both inhabit chiefly the south-eastern part of Australia. KEY TO SPECIES OF METRIOLAGRIA 1 (2) Elytra paler yellowish brown. Antennái segments I to III with several very long hairs, the remaining segments with the usual pubescence M. affinis (BOISDUVAL, 1835) 2 (1) Elytra dark brown, nearly blackish. Antennái segments I to VIII with very long hairs (Fig. 27) M. formicicola (LEA, 1894)
