Abstract
The genus Malgasodes is redefined; the type species M. curvisetus Mahunka, 2000, is redescribed by means of studies using optic and Scanning Electron Microsopy (SEM), and a complementary description of M. hungarorum Mahunka, 2000 is included. Comparison of genera Malgasodes Mahunka, 2000, Bovicarabodes Fernandez, Theron, Rollard, 2013a, Cavaecarabodes Fernandez, Theron, Rollard, Rodriguez Castillo, 2014, Afticarabodes Fernandez, Theron, Rollard, 2013b, and Congocepheus Balogh, 1958 is made. Problems concerning chaetotaxy, regressive evolution and neotrichy are explained and phylogenetic relationships between Malgasodes, Bovicarabodes, Afticarabodes, Congocepheus and Cavaecarabodes are discussed.
Highlights
For several years we have been working on a revision of the family Carabodidae
We rapidly understood how essential it was to study type material deposited in different Museums; and in general collaboration was very good, but in some instances type material was not available on loan (National Natural History Museum, Budapest), leading to problems in the development of our study
We report on Malgasodes curvisetus and Malgasodes hungarorum made available on loan from the Natural history Museum of Geneva, the totality of the species of this genus, with optic microscopy and Scanning Electron Microsopy (SEM)
Summary
For several years we have been working on a revision of the family Carabodidae. Many years ago, upon commencing our work on this family, we studied large collections of material, principally from Madagascar, Gabon, Namibia, South Africa and Argentina; later, other collections were studied with material from Antilles, Vietnam, Central African Republic, Morocco, Congo, Thailand, Korea, China, Costa Rica, Brazil, Paraguay, etc.We rapidly understood how essential it was to study type material deposited in different Museums; and in general collaboration was very good, but in some instances type material was not available on loan (National Natural History Museum, Budapest), leading to problems in the development of our study. Lamellae with la.ti, short, “shark tooth-like” (Figures 7, 17); le setae sausageshaped (Figure 17), roughly-spiculate surface, clearly visible (Figure 17 indicated by arrowh); ro phylliform, with rounded elevated central zone, delimited on each side by, depressed longitudinal furrow (Figure 17); n.a.d well discernible due to transparency (Figure 12); two pairs of setae (probably c1, c2) situated in the anterior part of n.a.d and close to d.sj, (Figures 4, 6, 12, 19 indicated by X), observating d.sj, complicated by presence of cerotegument and setae, requiring observation from different angles.
