Key to the genera of Spilopyrinae

This key is modified from Reid (2000), in which elytra of Hornius were wrongly described as pubescent, which is only true for H. grandis (Philippi & Philippi 1864) , and erroneous distributions were given for the South American genera (see Jerez 1996).

1 Lateral margins of pronotum with a distinct raised border ....................................................................................... 2

- Lateral margins of pronotum without raised border ................................................................................................. 5

2(1) Dorsum brown and non-metallic; pronotum broadest at middle, contracted anteriorly and posteriorly; length 7- 9mm ( Argentina and Chile) ....................................................................................................... Hornius Fairmaire

- Dorsal surface glabrous, usually partly metallic and black; pronotum shaped otherwise; length 9-15mm .............. 3

3(2) Dorsal surface wholly metallic, with spots and bands; body broader (length at most 1.8x width) and profile strongly raised in middle ( Australia and New Guinea) ..................................................................... Spilopyra Baly

- Dorsal surface brown or non-metallic green; body more elongate (length at least 2.5x width) and not arched longitudinally ................................................................................................................................................................... 4

4(3) Prosternal process narrow and feebly curved longitudinally, broadly expanded and shallowly bilobed at apex; basal half of elytra semistriate; anterior tibia with 2 apical spurs; basal ventrites not fused ( Chile).......................... ................................................................................................................................................... Stenomela Erichson

- Prosternal process flat, broad, parallel-sided, posteriorly raised and deeply bilobed at apex; elytra non-striate; anterior tibia with one apical spur; ventrites 1 and 2 fused ( New Caledonia) ....................... Bohumiljania Monrós

5(1) Upper surface extremely dull from microreticulation, clothed with recumbent scales; pronotum with small lateral teeth, or dorsal tubercles; claws bifid ( Australia) .......................................................................... Cheiloxena Baly

- Upper surface shining, almost glabrous, without scale-like setae; disc of pronotum non-tuberculate, but sides frequently with strong angular or rounded projection; claws simple ........................................................................... 6

6(5) Elytra with pair of large angular tubercles near scutellum, rugosely and irregularly punctured ( Australia).............. ..................................................................................................................................................... Richmondia Jacoby

- Elytra smooth, non-tuberculate and non-rugose ...................................................................................................... 7

7(6) Pronotal width at posterior angles greater than width at anterior angles; prosternal process depressed, transverse with bilobed apex ( Australia)...................................................................................................... Allsortsia gen. nov.

- Pronotal width at posterior angles less than width at anterior angles; prosternal process arched, elongate, with truncate or pointed apex ( Australia and New Guinea).................................................................... Macrolema Baly
