Key to the Iberian species of the Ochthebius (Asiobates) minimus species group

1 Outer margin of elytra without setae. Distal lobe of aedeagus simple, with apical half perpendicular to the proximal one in lateral view (see Jäch, 1990: fig.8) .................................................................................. O. minimus (Fabricius)

– Outer margin of elytra with setae (sometimes these setae are adpressed and/or rubbed away and therefore not easily recognizeable). Distal lobe of aedeagus composed of three parts: right lateral sclerite (LS), hyaline cone (HC) and apical tube (AT) (see Jäch, 1998: fig. 1a) ..................................................................................................................... 2

2 Pronotum and elytra pale brown. Elytral intervals flat. Distal lobe of aedeagus with LS elongate, without apical hook (see Jäch, 1990: fig. 1) ..................................................................................................................... O. aeneus Stephens

– Pronotum and elytra black (sometimes with greenish lustre). Elytral intervals convex. Distal lobe of aedeagus with LS wide, with a short apical hook (fig. 2) ..................................................................................... O. sanabrensis n. sp.
