Levey, B. & Bellamy, C. L., 2013, A taxonomic revision of Neobuprestis Kerremans (Coleoptera: Buprestidae) with the description of a new genus and two new species, Zootaxa 3681 (3), pp. 225-240 : 237

Key to the species of Burnsiellus

1 Metacoxal plate strongly widening to the femoral insertion, about twice as wide at the medial edge as at the lateral edge ( Fig. 31 ).................................................................................................. 3

- Metacoxal plate less strongly widening to the femoral insertion, about one and a half times as wide at the medial edge as at the lateral edge ( Fig. 30 )................................................................................... 2

2 Elytra purple-brown with black costae and small pulverulent white spots ( Fig. 9); underside entirely 'metallic' reddish purple and blue-green; Queensland........................................................... B. albosparsa (Carter)

- Elytra straw coloured with brown patches and black costae ( Fig. 7); underside largely 'metallic' purple-brown but anterior margin and lateral margin of prosternum yellow; W. Australia, S. Australia, Victoria.............. B. marmorata (Blackburn)

3 Elytral apices subtruncate, without well defined teeth ( Fig. 28 ); elytra very densely almost contiguously punctured between the costae; pronotum strongly narrowing to the anterior and posterior angles ( Figs. 10, 26 ); fronto-clypeus strongly depressed between the antennal insertions; mid tibia much broader than hind tibia, strongly swollen in male, with long tibial spurs which curve at the apex; posterior margin of 2nd visible ventrite simple ( Fig. 12); apex of last visible ventrite truncate, without lateral teeth ( Fig. 12), W. Australia, S. Australia, New South Wales................................ B. trisulcata (Carter)

- Elytral apices obliquely truncate, with well defined teeth ( Figs. 8, 29 ); elytra less densely punctured between costae; pronotum almost parallel sided ( Fig. 8); fronto-clypeus only slightly depressed between the antennal insertions; mid tibia about as broad as hind tibia, not swollen in male, with shorter, straight tibial spurs; posterior margin of 2nd visible ventrite with a large semitransparent lobe at the middle, covering part of the 3rd ventrite ( Fig. 11); apex of last visible ventrite slightly concave, with lateral teeth ( Fig. 11); Victoria.............................................................. B. lobatum sp. n.
