PROC. ENTOMOL. SOC. WASH. 85(3), 1983, pp. 439-449 TYPES OF NEOTROPICAL TELENOMINAE DESCRIBED BY W. H. ASHMEAD AND P. CAMERON (HYMENOPTERA: SCELIONIDAE) Norman F. Johnson Department of Entomology, 1735 Neil Avenue, The Ohio State University, Columbus, Ohio 43210. Abstract.— The status and location of primary types of Neotropical Telenominae described by P. Cameron and W. H. Ashmead are reviewed. Lectotypes are designated for Phamirus affinis Ashm., Telenomus albitarsis Ashm., T. cubiceps Ashm., T. difformis Ashm., T. flavivenths Ashm., T. flavopetiolatus Ashm., T. flavicornis Ashm., T. fuscicornis Ashm., T. impressus Ashm., T. luteipes Ashm.. T. magniclavus Ashm., T. nigriclavatus Ashm., T. pygmaeus Ashm., T. smithii Ashm., and Thssolciis laticeps Ashm. The holotypes of Telenomus confusus Ashm., T. fuscipennis Ashm., T. ineridionalis Ashm., and T. monilicornis Ashm. have been housed in the collection of the National Museum of Natural History, Wash-ington, D.C., since their description. All primary types described from telenomine material collected by H. H. Smith from the Lesser Antillean islands of St. Vincent and Grenada are deposited in the collection of the British Museum (Natural History), London. The systematics of the subfamily Telenominae (Hymenoptera: Scelionidae) has long been neglected. Most of the work on the New World species was conducted around the turn of the century. The short descriptions by these early workers generally are insufficient to recognize their species. The study of type specimens is therefore of primary importance. The types of Neotropical telenomines described by William H. Ashmead (1894, 1895a, 1895b) and Peter Cameron (1891, 1913) have been housed in the collec-tions of the National Museum of Natural History (USNM) in Washington, D.C., and the British Museum (Natural History) (BMNH) in London. Masner (1965) and Masner and Muesebeck (1968) have designated lectotypes and summarized information on many proctotrupoid species in these collections. Some species, however, were purposely not discussed in either paper in order to avoid misin-terpretation. For others there are discrepancies between published information and the specimens. This paper is intended to resolve these problems and provide a stable nomenclatural base for the taxonomy of Neotropical telenomines. Many of the syntype series discussed below are obviously samples of more than a single species. I have been very conservative in designating paralectotypes because of the difficult taxonomic problems in this subfamily. Except where noted, all ho-lotypes and lectotypes are now deposited in the collection of the British Museum (Natural History). I have therefore cited the USNM type numbers only on those specimens that actually bear the Museum's numbered type labels.
