Type species. Macrosiagon ebboi Perrichot, Nel et Néraudeau, 2004 . Etymology . Combination of the name of the type locality and the Latin suffix – cola (meaning inhabitant(s)). Masculine in gender. Te name is registered under ZooBank LSID urn:lsid:zoobank. org:act:D5E1D0C3-0B1C-4FA6-B2FB-1968308E3B6A. Material . Male holotype preserved as an amber inclusion found in Salignac, near Sisteron ( France ), Cretaceous (Cenomanian) [ 17 ]. Remarks . Tis species is interpreted not to belong to the subfamily Ripiphorinae (to which the genus Macrosiagon belongs) by Batelka et al. [ 19 ]. After re-examination of the male holotype, this species was tentatively excluded from Ripiphoridae , because of an unusual combination of characters: tibial spur formula 1-2-2; serrate pretarsal claws; putative biflabellate antennae (regarded as uniflabellate by [16: Fig. S3a]) with greatly prolonged thread-like antennal rami covered densely by long hair-like sensilla,reduced venation on hind wings; abdomen long, eight segmented with apex of ninth segment visible (sic), ultimate abdominal segment tapering posteriorly; very long hind legs; and very long metatibial spurs [16: Fig. S3, 17]. Its similarities in terms of characters with other Ripiphoridae considering the description of Melanosiagon gen. nov. are updated and discussed below.
