The male genitalia in the subfamily Agathidinae (Hymenoptera: Braconidae): Morphological information of species on generic level

The morphology of the male genitalia of 46 Agathidinae species belonging to 20 genera has been investigated. Samples from various geographical regions were used to discover the evolution of the male genitalia within the subfamily Agathidinae. Those male genitalia may contain important phylogenetic information at least in certain groups of Braconidae. For the New World, three of four investigated species of Cremnops (C. haematodes, C. montrealensis and C. vulgaris) could suggest the form of the new genus with the other members of New World Cremnops, partly because of the deviating morphology of the male genitalia. Comparative morphology of the male genitalia of Bassus confirms that it is polyphyletic. The status of Lytopylus (L. erythrogaster) is again actualised. Once synonymised as Aerophilopsis, this species could be excluded from other Lytopylus species. The statistical analysis showed that smaller specimens (<6.67 mm) give less details on the morphology of the male genitalia comparing to larger.
