Remarks. Eophileurus malyi Endrődi, 1978 was described from southern Thailand with no additional material known to literature since its discovery. The type series ( Figs. 71–78 ) clearly suggest its close relationship to E. confinis Prell, 1913 but the parameres are structurally different in having an extra pair of backward process at the center of the parameres in frontal view ( Fig. 73 ).
