NEW SPECIES OF AULACOPHORA FROM SABAH, MALAYSIA(COLEOPTERA: CHRYSOMEUDAE: GALERUCINAE)byMOHAMED S. MOHAMEDSAIDCentre for Insect SystematicsUniversiti Kebangsaan Malaysia, 43600 Bangi, MalaysiaABSTRACTThree new species of Aulacophora are described from Sabah,Malaysia: A. danumensis n.sp., A. irpa n.sp. and A. kinabaluensis n.sp.Aulacophora coffeae 'and A. indica are reported as new records forBorneo.INTRODUCTIONThe new species of Aulacophora Chevrolat herein described arethose with the elytra entirely brownish or yellowish. Presently, thereare two species with the said elytral coloration recorded from Borneo(Aulacophora corn uta Baly, and a variety of Aulacophora luteicornis(Fabricius)). This paper presents three descriptions of new species ofAulacophora from Sabah, and an additional two species as newrecords for Borneo. All specimens, including holotype are deposited inthe Insect Collection, Centre for Insect Systematics, UniversityKebangsaan Malaysia, Bangi (UKM). Some of the para types will bedeposited elsewhere.SYSTEMATICSKey to species of Aulacophora from Borneo(with the elytra yellowish or brownish, not black)1.
