Synonymized by Mazur, 1984 : 275 . Type species: Pachycraerus ( Coryphaeus ) wallacei Marseul, 1864 : 311 , by monotypy. Procoryphaeus : Mazur (1984) : 275 ; Mazur (1997) : 41 ; Mazur (2011) : 38 . Diagnosis. Rather large Exosternine Histeridae beetles, with blue to light green metallic bodies, cuticle occasionally dark, but always with metallic lustre. At least pleura and sterna covered with tiny dense setae, in the case of one species, P. pilosus , the entire body surface setose. Frons with deep depression on postero-median area; fronto-clypeal depression present. Pronotal disc laterally with dense foveolate-variolate confluent punctures; apical angles always impunctate; pre-scutellar area with variously prominent tiny tubercle. Elytra with 3-5 complete discal striae, sutural stria in most cases absent or indiscernible. Prosternum with index finger-like groove between lateral prosternal stria and prosternal keel; between lateral pronotal stria and pronotal keel another carinate stria present delimiting the prosternal keel. Mesoventrite rather small; metaventrite almost glabrous; procoxae massive; tibiae flattened and slightly dilated. Tenth tergite small and thin, keel like; basal piece of aedeagus about twice as long as its tegmen. Biology. Unknown. A specimen from Thailand was collected using flight intercept trap. Distribution. This genus includes three described species: Procoryphaeus wallacei ( Marseul, 1864 ) described from Dorey [=Manokwari] ( Indonesia : Papua ); Procoryphaeus violaceus ( Lewis, 1905 ) described from Mount Kina Balu, Borneo , Malaysia , occurring also in Indonesia (Java, Sumatra and Papua ) and Thailand (Tenasserim Mountains); and Procoryphaeus pilosus ( Lewis, 1893 ) known only from the Tanimbar Island, Indonesia .
