Hemiphileurus rugulosus Endrödi

Ratcliffe, Brett C., 2001, New Species Of Hemiphileurus Kolbe (Coleoptera: Scarabaeidae: Dynastinae) From Mexico, Guatemala, Colombia, And Brazil, The Coleopterists Bulletin 55 (4), pp. 433-443 : 438

Hemiphileurus rugulosus Endrödi

( Figs. 11–13 )

Hemiphileurus rugulosus Endrödi 1978:91 .

Endrödi described this species based on 43 specimens, most of which were from Venezuela ; two specimens were from Colombia . Endrödi’s (1985) key to the species of Hemiphileurus generally works for identifying this species, but when one attempts to confirm the identification by comparing the parameres of the specimen with the illustration in the book, considerable doubt sets in because the two don’t appear to be the same. The reason for this is the oversimplified illustration which, unfortunately, is typical for so many of the drawings by Endrödi. When compared with specimens identified by Endrödi, the illustration is simply not accurate.

To help alleviate this confusion, I am providing new illustrations ( Figs. 11– 12 ) of the male genitalia of H. rugulosus specimens collected at Rancho Grande (near Maracay), Venezuela as well as Endrödi’s original drawing ( Fig. 13 ).
