A phylo- genetic analysis of these two families based on larval morphology is presented. Fifty-four larval morphological and three biological characters from twenty-seven taxa revealed nineteen equally parsimonious cladograms. The monophyly of (Ceratocanthidae þ Hybosoridae) is supported by four unambiguous unique syna- pomorphies: dorsal medial endocarina on cranium extended anteriorly into fron- tal sclerite; presence of large membranous spot on apical antennomere; labium dorsally with four pores in centre (secondarily reduced to two pores in some groups); and presence of stridulatory organ on fore- and middle legs (secondarily reduced in some groups). Our analysis suggests that the family Hybosoridae is paraphyletic with respect to Ceratocanthidae. The clade comprising the hybosorid genera Hybosorus and Phaeochrous is the sister group of the remaining Hybo- soridae plus Ceratocanthidae. It is supported by two unambiguous synapomorphies: two apical antennomeres completely joined and the stridulatory organ represented by seven to nine large teeth anteriorly on the middle leg. The hybosorid genus Anaides is a sister group to the remaining Hybosoridae plus Ceratocanthidae (without Hybosorus and Phaeochrous) and the ceratocanthid genus Germarostes is a sister group to the remaining Hybosoridae plus Ceratocanthidae (without Hybosorus, Phaeochrous and Anaides). The ceratocanthid genera Cyphopisthes, Astaenomoechus, Paulianostes, Pterorthochaetes, and Madrasostes constitute a sister group to the hybosorid genus Cryptogenius and are supported by the presence of two reversions: two dorsal pores on labium and completely reduced stridulatory organs on fore- and middle legs. 1 aGrebennikov, Vasily, V.1 aBallerio, Alberto1 aOcampo, Federico, C.1 aScholtz, Clarke, H.  uhttps://scarabnet.myspecies.info/larvae-ceratocanthidae-and-hybosoridae-coleoptera-scarabaeoidea-study-morphology-phylogenetic-analys01379nas a2200193   4500008004100000245019400041210006900235300001000304490000700314520060100321653001300922653001700935653001300952653002000965653001800985100002501003700001901028856013801047       2005                        eng d00aFood relocation and nesting behavior of the Argentinian dung beetle genus Eucranium and comparison with the southwest African Scarabaeus (Pachysoma) (Coleoptera: Scarabaeidae: Scarabaeinae)0 aFood relocation and nesting behavior of the Argentinian dung bee  a53-590 v643 aThe food relocation and nesting behavior of the South American genus Eucranium Brullé is described based on observations carried out under natural conditions. Food preference, food transportation, period of surface activity, and habitat preference are described for two species, E. arachnoides Brullé and E. planicolle Burmeister. The biology and food relocation behavior of Eucranium is compared with that of the morphologically similar South African subgenus Scarabaeus (Pachysoma) MacLeay. The convergent adaptations to psamophilous habitats of Eucranium and S. (Pachysoma) are discussed. 10abehavior10aDung beetles10aendemism10aFOOD RELOCATION10axeric habitat1 aOcampo, Federico, C.1 aPhilips, Keith  uhttps://scarabnet.myspecies.info/food-relocation-and-nesting-behavior-argentinian-dung-beetle-genus-eucranium-and-comparison-southwes
