Revision of the Afrotropical Phaeogenini (Ichneumonidae, Ichneumoninae), with description of a new genus and twelve new species Author Rousse, Pascal Author van Noort, Simon Author Diller, E. text ZooKeys 2013 354 1 85 http://dx.doi.org/10.3897/zookeys.354.5968 journal article http://dx.doi.org/10.3897/zookeys.354.5968 1313-2970-354-1 EF025B9C50EC4CC886BBAE8C1F4E9CF1 Lusius Tosquinet, 1903 Mesochorischnus Heinrich, 1938 Diagnosis. Lusius is also a very distinct genus of Phaeogenini , close to Heterischnus . It can be separated from other genera in the tribe by the combination of the following characters: head hemispherical; mandible unidentate and falcate; basal flagellar segments slender and long; vertex long and slightly convex behind ocelli; occipital and hypostomal carinae joining at mandibular base; notaulus complete, ending posteriorly in a median depression; fore wing with areolet open, hind wing with distal abscissa of Cu1 absent; gastrocoelus long with thyridium faint; ovipositor extending beyond apex of metasoma; male with gonoforceps mesochorine-like , i.e. expanded into elongate process ( Tosquinet 1903 , Baltazar 1964 ; Diller 2006 ). Species richness and distribution. The genus is represented by seven species in the Afrotropical, Neotropical and Oriental regions, with one Afrotropical species. We describe here a new species from Uganda.
