Review of the Palearctic Aphelinoidea (Hymenoptera: Trichogrammatidae), with focus on the species described by Ś. Nowicki

Abstract

Type specimens of Aphelinoidea anatolica Nowicki, A. anatolica melanosoma Nowicki (now A. melanosoma), A. deserticola Nowicki, and A. subexserta Nowicki (Hymenoptera: Trichogrammatidae), which were not examined by taxonomists since their original descriptions had been published, are identified, labeled, re-diagnosed, and illustrated. A lectotype is designated for A. anatolica. Taxonomic notes on these Palearcic taxa and also some other species of Aphelinoidea Girault in the Holarctic Region are provided along with a key to females of the Palearctic species. The subgenus Aphelinoidea (Diaclava) (Blood & Kryger), n. syn., is synonymized under the nominate subgenus, A. (Aphelinoidea) Girault, and its type species Diaclava waterhousei Blood & Kryger is transferred to the latter as A. (Aphelinoidea) waterhousei (Blood & Kryger), rev. stat. Aphelinoidea (Krygeriola) dolichoptera Nowicki, n. syn., and A. gwaliorensis Yousuf & Shafee, n. syn., are synonymized under A. (Lathromeroides) neomexicana (Girault), and A. retiruga Lin, n. syn., is synonymized under A. (Aphelinoidea) longiclavata Yousuf & Shafee. A new taxon, A. (Aphelinoidea) gerlingi n. sp., is described; it is known from specimens collected in Algeria, Egypt, Israel, Morocco, and Oman, and also, including the holotype, from vouchers of the colonies introduced (misidentified as A. anatolica) from Iran into California, USA, for biological control against the beet leafhopper, Neoaliturus (Circulifer) tenellus (Baker) (Hemiptera: Cicadellidae). To prevent further damage, most of the examined specimens in the Ś. Nowicki collection of Aphelinoidea at its current depository, the Entomological Collection of Dipartimento di Entomologia e Zoologia Agraria «Filippo Silvestri», Università degli Studi di Napoli «Federico II», Portici, Italy, were remounted into Canada balsam from the dried and often darkened original water-soluble mountant.
