Extensive sampling and thorough taxonomic assessment of Afrotropical Rhyssinae (Hymenoptera, Ichneumonidae) reveals two new species and demonstrates the limitations of previous sampling efforts Author Hopkins, Tapani Author Roininen, Heikki Author Noort, Simon van Author Broad, Gavin R.

Type material : NIGERIA: • 1 ♀, holotype; "Ilorin Prov." [ 06°48'N , 05°18'E ]; "18 Jun. 192" [18 Jun 1921?]; "De. G.W.S. Macfie" leg.; "Pres. by Imp. Bur. Ent. 1921 -129" ; NHMUK. Known material : One specimen (1 ♀, see Rousse and van Noort 2014 , data above). Diagnosis. This species can be distinguished from other Afrotropical Rhyssinae by the combination of lateral carinae on the frons and the absence of a raised flange on the dorsal margin of the mesopleuron. No other species has the same colour pattern. Head : frons with median carinae diverging towards ocelli, with lateral carinae curving towards lateral ocelli; hypostomal carina raised into an elevated flange, its height greater than the maximum width of the second maxillary palp segment. Mesosoma : subalar prominence without a lateral flange; mesopleuron without a flange along the dorsal margin; epicnemial carina reaches the approximate height of the mesopleural pit. Metasoma : tip of apical horn elliptical in posterior view; tergite 3 mostly smooth. Distribution. Nigeria. Figures 68-71. Epirhyssa villemantae female (holotype).
