Comments.

Prolonged large representative of Debus . Elytral declivity deeply excavated, edge of declivity with two pairs of long teeth, but only few tubercles. Declivital surface smooth.

Debus amphicranoides (Hagedorn) possibly senior synonym of the following (NHMW): Debus birmanus (Eggers), Debus cyclopus (Schedl), Debus interponens (Schedl), Debus robustipennins (Schedl). Debus birmanus identical except slightly larger, with slightly longer declivital posterolateral processes, much smaller upper tooth on declivity. Debus interponens similar except lacks constricted declivity and has shorter posterolateral declivital processes. Schedl (1954) considered Debus (as Xyleborus) interponens possible altitudinal variation of Xyleborus robustipennins ; the two essentially identical, origi nated from different elevations. Debus cyclopus similar except narrower elytral apical emargination. Debus robustipennis larger. Schedl (1954) mentioned that it only differed from Debus amphicranoides in minor differences in declivital teeth shape.
