Propleuron and mesepisternum finely punctured, Structure of the internal middle lobe of the male metepisternum and metasternum strongly densely aedeagus is shown in ( fig. 13 ­ 16). Protuberances punctured. Abdomen smooth. BLI and BLD big and symmetrical, have same Structure of the internal middle lobe of the male size. Basal protuberance (B) protruding and well aedeagus is shown in (fig. 17­ 19). Protuberances visible. BLI and BLD asymmetrical, BLD much bigger. Etymology. Named after coleoptera enthusiast Basal protuberance not protruding. from Poland, Tomasz Gazurek who collected the Etymology. Named after Cándido Bolívar Pieltain new species. (1897–1976) who collected the specimens. Differencial diagnosis. Is given below, in Cándido Bolívar Pieltain was a prominent Spanish comparation with related species P. bolivari sp.n. entomologist. and P. emblema . Differencial diagnosis. This new species is well distinct from any other Platyderus from Iberian peninsule by numerous external morphological Platyderus bolivari sp.n. caracters and endofallus structure. The new species is from “ ruficollis-subcrenatus” group Holotype: male, Cala, Huelva, 15.2.1915 C. of species and related to P. emblema and P.
