(Ecuador, Galapagos Islands), Neodryinus mayanus Olmi & Virla, sp. nov. (Honduras), and Peckius insularis Olmi & Virla, sp. nov. (Ecuador, Galapagos Islands). The following new synonymies are presented: Deinodryinus kawensis Olmi 2011b (April) (=D. caxiuana Coelho, Aguiar & Engel, 2011 (June), syn. nov.); Dryinus gibbosus Olmi, 1984 (=D. multicarinatus Coelho, Aguiar & Engel, 2011, syn. nov.); Dryinus striatus (Fenton, 1927) (=D. sinopensis Olmi, 1984, syn. nov.; =D. cerrensis Olmi, 2004a, syn. nov.); Gonatopus Ljungh, 1810 (=Trichogonatopus Kieffer, 1909, syn. nov.); Eucamptonyx dromedarius (Cameron 1888) (=E. hansoni Olmi, 1991, syn. nov.); Haplogonatopus hernandezae Olmi, 1984 (=H. crucianus Olmi, 1986, syn. nov.). The following new combinations are proposed: Eucamptonyx dromedarius (Cameron, 1888), comb. nov. (from Gonatopus); Gonatopus goiasensis (Olmi 1991), comb. nov. (from Trichogonatopus); G. hispidus (Olmi 1984), comb. nov. (from Trichogonatopus); G. longinoi (Olmi, 1998d), comb. nov. (from Trichogonatopus); G. marinoae (Virla, 1997), comb. nov. (from Trichogonatopus); G. neotropicus (Olmi, 1984), comb. nov. (from Trichogonatopus); G. raptor (Fenton, 1927), comb. nov. (from Chalcogonatopus); G. rubriceps (Kieffer, 1909), comb. nov. (from Trichogonatopus); G. stellaris (Virla, 1997), comb. nov. (from Trichogonatopus). The male of Crovettia brasiliana Olmi 1984, is described for the first time.
TL;DR: Gonatopus amazonicus Olmi is redescribed and illustrated based on a single female reared from an adult parasitized leafhopper belonging to the genus Frequenamia DeLong (Cicadellidae, Deltocephalinae), collected by sweeping on Eugenia uniflora L. in Southern Brazil.
Abstract: Gonatopus amazonicus Olmi is redescribed and illustrated based on a single female reared from an adult parasitized leafhopper belonging to the genus Frequenamia DeLong (Cicadellidae, Deltocephalinae), collected by sweeping on Eugenia uniflora L in Southern Brazil This female emerged 46 days after pupation
TL;DR: The fauna of Dryinidae and Embolemidae from Anijima in Ogasawara Islands, Japan is surveyed and Gonatopus tambiniae (Esaki & Hashimoto) is recorded for the first time from AnIJima.
Abstract: The fauna of Dryinidae and Embolemidae from Anijima in Ogasawara Islands, Japan is surveyed. Five species of Dryinidae and one of Embolemidae. Gonatopus adelphos Mita & Olmi, sp. nov. and Ampulicomorpha viator Mita & Olmi, sp. nov. are described and illustrated. Gonatopus tambiniae (Esaki & Hashimoto) is recorded for the first time from Anijima. Anteon achterbergi Olmi, Gonatopus nigricans (R. Perkins) are recorded for the first time from Ogasawara Islands. The male of Dryinus sinicus Olmi is described for the first time. Gonatopus hagoromo Terayama & Ohbayashi is considered junior synonymous of Gonatopus tambiniae (Esaki & Hashimoto).
TL;DR: The key to the Neotropical species of Gonatopus group 7 is modified to include this new species, which is similar to G. peruvianus Olmi, from Peru.
Abstract: Gonatopus duranprietoae sp. nov. (Hymenoptera: Dryinidae: Gonatopodinae) from Colombia is described and illustrated. This new species belongs to Gonatopus group 7. In this group, G. duranprietoae is similar to G. peruvianus Olmi, from Peru. The main difference between these two species is the shape of the metanotum: in G. duranprietoae lateral regions with two small pointed protrusions, which are absent in G. peruvianus. The key to the Neotropical species of Gonatopus group 7 is modified to include this new species.
TL;DR: An updated revision of Eastern Palaearctic Dryinidae is presented, together with illustrations of the main morphological characters and keys to the subfamilies, genera and species.
Abstract: An updated revision of Eastern Palaearctic Dryinidae is presented. Six subfamilies, 17 genera and 160 species are treated. Descriptions, geographic distribution, known hosts, natural enemies and type material of each species are presented, together with illustrations of the main morphological characters and keys to the subfamilies, genera and species. Complete lists of references concerning the Eastern Palaearctic Dryinidae and their hosts are given. The lectotype is designated for Anteon flaviscapus Jansson, 1950. A new combination is proposed for Mirodryinus olmii (Moczar, 1983), comb. nov. (from Radiimancus Moczar). The following new records are reported: Aphelopus prolatus Mita & Olmi, 2014 and Gonatopus formicicolus Richards, 1939 from Sweden; Aphelopus querceus Olmi, 1984, Aphelopus serratus Richards, 1939 and Anteon reticulatum Kieffer, 1905 from Bulgaria; Gonatopus nigricans (R. Perkins, 1905) from Solomon Islands; Haplogonatopus oratorius (Westwood, 1833) from Germany and Sweden.
