Abstract

The Oriental genus Genyocerus Motschulsky is reviewed and distinguished from the closely related genus Diapus Chapuis.  The following new synonyms are proposed:  Genyocerus biporus Schedl (=Diacavus intermedius Browne); Genyocerus diaphanus (Schedl) (= Diacavus abdominalis Schedl,  =Diacavus philippinensis Schedl, = Diacavus sexporus Schedl); Genyocerus frontalis (Strohmeyer) (= Diacavus longicollis Browne); Genyocerus multiporus (Schedl) (= Diacavus decemspinatus Schedl); Genyocerus pendleburyi (Schedl) (= Diapus albipennis Strohmeyer nec Motschulsky, = Genyocerus strohmeyeri Wood); Genyocerus puer (Schedl) (= Genyocerus puer trispinatus (Browne); Genyocerus quadriporus (Schedl) (= Diacavus compactus Schedl, = Diacavus compactus dubiosus Schedl,= Diacavus quadridens Browne, =Diacavus quadrifoveolatus Schedl); Genyocerus talurae (Stebbing) (= Genyocerus dipterocarpi Browne).  Keys are provided to males and females.  The previously unknown females of G. borneensis (Schedl) and G. frontalis are described.  The species are almost entirely restricted in their hosts to trees of the family Dipterocarpaceae.
