Species of Platygastrinae and Sceliotrachelinae from rainforest canopies in Tanzania, with keys to the Afrotropical species of Amblyaspis, Inostemma, Leptacis, Platygaster and Synopeas (Hymenoptera, Platygastridae) Peter Neerup Buhl The platygastrid diversity from a canopy fogging experiment in Tanzania is assessed, a total of about 1140 specimens in 141 species was found. Forty species new to science are described: Allotropa canopyana, A. fusca, Leptacis acuticlava, L. dendrophila, L. dilatispina, L. ioannoui, L. johnsoni, L. kryi, L. laevipleura, L. latipetiolata, L. mckameyi, L. papei, L. piestopleuroides, L. popovicii, L. pronotata, Parabaeus austini, P. brevicornis, P. papei, Platygaster hamadryas, Pl. kwamgumiensis, Pl. leptothorax, Pl. mazumbaiensis, Pl. nielseni, Pl. sonnei, Pl. ultima, Pl. vertexialis, Synopeas acutanguliceps, S. canopyanum, S. ciliarissimum, S. dentilamellatum, S. dorsale, S. fredskovae, S. glabratum, S. gnom, S. laeviventre, S. lineae, S. longiceps, S. mazumbaiense, S. semihyalinum, and S. verrucosum. Keys are given to nearly all known Afrotropical species of Amblyaspis Förster, 1856, Inostemma Haliday, 1833, Leptacis Förster, 1856, Platygaster Latreille, 1809 and Synopeas Förster, 1856.
