Abstract
The genus Machadocepheus, being one of the more complex genera of the Carabodidae family, is briefly outlined to demonstrate this complexity. Descriptions of two new species from Gabon, Machadocepheus leoneae sp. n. and Machadocepheus rachii sp. n. are given.
Highlights
IntroductionThis genus was created by Balogh in 1958 (page 20), with type species Machadocepheus excavatus Balogh, 1958 (page 21), but in very brief text lacking figures
We studied most species cited, except for Machadocepheus manguiati CorpuzRaros, 1979, which we were unable to obtain, and Machadocepheus longus Balogh, 1964, which was not available on loan from HNHM
Thereafter, we aim to study type material where only optical microscopy studies are available, with the intention of clarifying the taxonomy of Machadocepheus and related genera
Summary
This genus was created by Balogh in 1958 (page 20), with type species Machadocepheus excavatus Balogh, 1958 (page 21), but in very brief text lacking figures. The species Machadocepheus papuanus Balogh, 1970 (from New Guinea), was instated as the type species of the genus Guineobodes, erected by Mahunka 1987, and is considered by Subias (2004 updated 2014) to be a subgenus of Pasocepheus Aoki, 1976, as Pasocepheus (Guineobodes) (Mahunka 1987). Machadocepheus manguiati Corpus-Raros, 1979 was designated the type species of Philippobodes J & P Balogh, 1992, considered by Subias (2004, updated 2014) as synonym of Bathocepheus Aoki, 1978, transferring the species to Bathocepheus manguiati (Corpus-Raros, 1979). The genus Kalloia was created by Mahunka 1985, with K. simpliseta Mahunka, 1985 as type species; at present, this species has been recombined as Machadocepheus (Kalloia) simpliseta (Mahunka, 1985)
