The Hymenoptera (Chalcidoidea, Ichneumonoidea, Platygastroidea) described by Vittorio Delucchi: an annotated catalogue Author Baur, Hannes text Journal of Natural History 2001 2001-01-31 35 1 55 125 http://www.tandfonline.com/doi/abs/10.1080/002229301447899 journal article 10.1080/002229301447899 1464-5262 5275865 Skeloceras cerebrosum Delucchi (Pteromalidae) Skeloceras cerebrosum Delucchi, 1955a: 21 , 24. Holotype m, Germany (NMW [examined]). Material . HOLOTYPE m (cr, left pedicel with ¯agellum, right ¯agellum beyond ®rst segment, and left fore leg beyond trochanter lacking, body glued with original micro-pin to card rectangle) labelled`p. 232. o. Or. Ex. m.; [empty label]; Collect. G. Mayr; Lamp. sulcatulus FoÈrster , Type; [cp, yellow]; SKELOCERAS cerebrosum n. V. Delucchi det.; TYPE [red]’. Remarks . Delucchi described the female and stated`Type deÂpose au MuseÂum d’Histoire Naturelle de Vienne .’ but did not specify the number of specimens he had. Holotype subsequently remounted from micro-pin by me. It is a specimen from the FoÈrster collection. One male (dp) in the NMW provided only with Delucchi’s identi®cation label is not considered as part of the type series, since the male was not described. Delucchi (1955a: 21) separated cerebrosum from Lamprotatus truncatus (Fonscolombe) [sub Skeloceras mirabile Delucchi ] by diOEerences in the sculpture of the propodeum. Examination of 25 females and 16 males from Northern and Central Europe, Croatia , France , and Italy ( BMNH , MG , MHNG , MZL , NMBE , NMW , VD , ZB ) showed that this character is quite variable. The sculpture consists of some oblique striae which sometimes may indicate an irregular median carina or a costula, though the latter is never as distinct as e.g. in L. novickyi (Delucchi) . With regard to this variation cerebrosum certainly lies within the range of variation of truncatus . Status . Junior synonym of Lamprotatus (Skeloceras) truncatus (Fonscolombe) syn. n.
