Key to species of Rhabdogaster View in CoL View at ENA

Notes: The key is chiefly designed for use with pinned male specimens. Some specimens may show irregular and asymmetrical patterns of pruinescence. This is often a sign of wear and allowance must be made for possible damage of this kind. Microtrichia are best viewed with backlighting. The word ‘predominantly’ is used when some specimens show some slight variation. It is essential to check identifications arrived at using this key, by referring to descriptions and illustrations of male terminalia. 1 Postmetacoxal bridge entirely pruinose ................................................................ 4
