Parameristomerinx copelandi — a new genus and species of Afrotropical Pachygastrinae and a new generic synonym of Dolichodema Kertész (Diptera: Stratiomyidae) Author Woodley, Norman E. text Zootaxa 2010 2397 41 47 journal article 10.5281/zenodo.194003 7f66e3fe-491e-489e-80f4-18d161547164 1175-5326 194003 Dolichodema fenestratum James Dolichodema fenestrata James 1949a : 5 . Nemodema nudibasis Lindner 1958 : 122 . Syn. n. The original description of Dolichodema fenestratum indictes that it is very similar to Lindner’s taxon, N. nudibasis . This was confirmed by examining a photograph of the holotype of D. fenestratum available on the internet (http://research.amnh.org/invertzoo/ types _db/) and comparing it to the holotype of N. nudibasis . No significant differences were found, and I regard the two taxa as conspecific. Additional specimens have been examined from other African localities, so the distribution of the species can be summarized as Afrotropical: Kenya , Liberia , Namibia , South Africa , Zimbabwe . Dolichodema fenestratum is probably a vespid wasp mimic, and is more modified than D. africanum and one undescribed species of Dolichodema that I have seen. The fourth and fifth sternites are convex and give the end of the abdomen a more wasp-like, convex and rounded appearance compared to the other two species. Both D. fenestratum and the undescribed species have a transparent “window” on abdominal segments 2 and 3 which presumably give the abdomen a petiolate apperance in flight, similar to that found in Hermetia illucens (Linnaeus) .
