New synonymy and taxonomic changes in bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae, Platypodinae)

New synonymy is proposed as follows: Scolytinae: Cryphalini: Cryphalus submuricatus EICHHOFF (= C. tuberculatus SCHEDL); Hypothenemus birmanus (EICHHOFF) (= Stylotentus dubius SCHEDL); Hypothenemus brevicollis (EGGERS) (= Stephanoderes lamuensis EGGERS); Dryocoetini: Cyrtogenius STROHMEYER (= Dendrographus SCHEDL); Dryocoetiops kepongi SCHEDL (= Pseudopoecilips taradakensis MURAYAMA); Hylesinini: Hapalogenius africanus (EGGERs) (= Xylechinus uniformis SCHEDL); Ipini: Acanthotomicus insularis (EGGERS) (= Ips kepongi SCHEDL, = I. inclinans SCHEDL); Micracini: Lanurgus podocarpi SCHEDL (= L. bicolor SCHEDL, = Traglostus brevisetosus SCHEDL); Lanurgus rhusi SCHEDL (= Traglostus spatulatus SCHEDL); Lanurgus widdringtoniae SCHEDL (= Glostatus perplexus SCHEDL); Lanurgus xylographus SCHEDL (= L. oleaeformis SCHEDL); Phloeosinini: Hyledius cribratus (BLANDFORD) (= Phloeosbms austrahs SCHEDL, = P. tuberculosus BROWNE); Hyledius vilis (BLANDFORD) (= Hylurgulus sumatranus EGGERS, = Phloeosinus borneensis SCHEDL); Xyleborini: Ambrosiophilus metanepotulus (EGGERS) (= Xyleborus hunanensis BROWNE); Arixyleborus imitator (EGGERS) (= A. dipterocarpi BROWNE); Cyclorhipidion circumcisum (SAMPSON) (= Xyleborus subobtusus SCHEDL); Cyclorhipidion .fukiensis (EGGERS) (= Xyleborus ganshoensis MURAYAMA); Debus cavulus (BROWNE) (= Xyleborus cavuloides BROWNE); Debris detritus (EGGERS) (= Xyleborus maniensis BROWNE); Debus pumilus (EGGERS) (= Xyleborus neocylindricus SCHEDL); Fortiborus posticepilosus (SCHEDL) (= Ozopemon major STROHMEYER); Microperus kadoyamaensis (MURAYAMA) (= Xyleborus huangi BROWNE); Xyleborus volvulus (FABRICIUS) (= X. continentalis EGGERS); Xyloctonini: Ctonoxylon uniseriatum SCHEDL (= C. capensis SCHEDL); Platypodinae: Platypodini: Platypus levannongi SCHEDL (= P. beaveri BROWNE). The following new combinations are given: Debus cavulus (BROWNE), D. cylindricus (EGGERS), D. detritus (EGGERS), Fortiborus posticepilosus (SCHEDL) all from Xyleborus. The following new replacement names are proposed for junior homonyms: Cyrtogenius borneanus for C. (Eidophelus) borneensis (BROWNE), Cyrtogenius gracilior for C. (Eidophelus) gracilis (BROWNE). Cyrtogenius longipennis (BROWNE) is resurrected as the correct name for C. elongatissimus WOOD.
