Pw. Kovarik et S. Passoa, CHAETOTAXY OF LARVAL HISTERIDAE (COLEOPTERA, HYDROPHILOIDEA) BASED ONA DESCRIPTION OF ONTHOPHILUS-NODATUS LECONTE, Annals of the Entomological Society of America, 86(5), 1993, pp. 560-576
Both instars of the relatively generalized histerid Onthophilus nodatu
s J. E. LeConte, are described and illustrated. This is the first larv
al description for the genus Onthophilus and is the first study of cha
etotaxy of histerid larvae. Setae of the thorax and abdomen are serial
ly homologized to develop a setal nomenclature for the first instar. T
his system is easily applied to other histerid genera.
