Remarks Förster described Leptacis on the basis of a long and pointed mesoscutellar spine, ocular ocellar length (OOL) less than lateral ocellar length (LOL), and four-segmented clava in the female. The type species of Leptacis is Ichneumon tipulae Kirby, 1798 , the type specimen of which is in the NHMUK. The NHMW includes paralectotypes of L. scutellaris Thomson, 1859 and L. torispinula Huggert, 1980 . Huggert (1980) synonymized L. scutellaris with L. tipulae . Vlug (1985) synonymized L. torispinula with L. nydia ( Walker, 1835 ) . Fig. 9. Isostasius punctiger ( Nees 1834 ) , original exemplar (NHMW-HYM#0005325). A . Anterolateral head. B . Lateral habitus. C . Dorsolateral habitus. D . Ventrolateral habitus. One specimen of Platygaster spinigera Nees, 1834 (NHMW-HYM#0005297), identified by Förster, rightfully belongs to Leptacis and the label on this specimen is consistent with Nees’s style ( Graham 1988 ). However, another specimen identified as P. spinigera in NHMW (NHMW-HYM#0005298) belongs to Synopeas . Based on the authenticity of the label, we consider the former specimen to be part of the syntype series and the latter specimen to be misidentified. We here designate NHMW-HYM#0005297 as the lectotype of Platygaster spinigera Nees, 1834 and transfer it to Leptacis .
