The genus Synaldis Foerster, 1863 (Hymenoptera: Braconidae: Alysiinae) in the Neotropical region: fi rst record, descriptions of new species and a key to the New World taxa. European Journal of Taxonomy 386: 1–28. https://doi.org/10.5852/ejt.2017.386 Introduction The status of the Alysiinae genus Synaldis Foerster, 1863 has been uncertain for a long time. Van Achterberg (1988) revised the Aspilota genera group and synonymized this genus with the re-established genus Dinotrema Foerster, 1863 on the basis of the plesiomorphic state of the unenlarged paraclypeal pits. As a result, he distributed the former species of Synaldis among the genera Aspilota Foerster, 1863 and Dinotrema according to the new diagnostic feature, the size of the paraclypeal areas. However, such a synonymy of Synaldis was not supported by several experts working on alysiine taxa (Fischer 1993a, 1993b; Papp 2000; Belokobylskij 2002). It is necessary to underline that such an apomorphic feature, as the complete reduction of vein 2-SR, is an evolutionary event which was also accompanied by the disappearance of the break (corner) between veins r and 3-SR, this part of the veins is only gently and relatively widely curved. Such an apomorphic state of the wing venation represents an important qualitative transformation and can reliably support the generic status of Synaldis (Belokobylskij 2002) 1 © European Journal of Taxonomy; download unter http://www.europeanjournaloftaxonomy.eu; www.zobodat.at European Journal of Taxonomy 386: 1–28 (2017) in spite of the rare present reduction of vein 2-SR in some specimens of a few species of Dinotrema. For that reason, we prefer to keep the generic status for Synaldis until any results of a molecular phylogenetic study of taxa of Alysiinae. Rather recently, Fischer (2003) established the genus Adelphenaldis, whose species differ from Synaldis only by the length of the paraclypeal fovea, which reaches the margin of the eye in Adelphenaldis, and is thus equivalent to the species of ‘Synaldis’ that Van Achterberg (1988) placed in Aspilota. Peris-Felipo & Belokobylskij (2016) published a key for the identifi cation of these four related genera. The genus Synaldis comprises about a hundred species described in the Afrotropical, Oriental, Australasian, Oceanic, Nearctic and Palaearctic regions (Fischer 1962, 1967a, 1967b, 1971, 1993a, 1993b, 2003; Belokobylskij 2002, 2004a, 2004b; Belokobylskij & Tobias 2007; Peris-Felipo et al. 2014b). The genus, however, had not been discovered in the Neotropical region until the present work. Members of the genus Synaldis are often reared from agaric mushrooms and recorded as parasitoids of the larvae and puparia of the dipterous families Phoridae (mainly) and Drosophilidae (doubtfully) (Hussey 1960; Fischer 2005; Yu et al. 2012). In this paper, the genus Synaldis is recorded for the fi rst time from the Neotropical region. Five new Neotropical species, S. brasiliense Peris-Felipo, sp. nov., S. fritzi Peris-Felipo, sp. nov., S. longifl agellaris Peris-Felipo, sp. nov., S. novateutoniae Peris-Felipo, sp. nov. and S. magnioculis Peris-Felipo, sp. nov., are described and illustrated. The combination, Synaldis ulmicola Ashmead, 1889 stat. rev., is also proposed after type revision. The records of the Nearctic species S. cabinica Fischer, 1967 in Korea and Russia (Far East) (Papp 1996; Belokobylskij 2002) and S. exitiosae Fischer, 1967 in Turkey (Beyarslan & Inanç 1992) are very doubtful and we exclude these regions in the distributions in our key.

A list of studied type material of the previously described New World species and place of their preservation. * This species was originally described as Synaldis ulmicola by Ashmead (1889), however Fischer (1967b) placed it in the genus Aspilota as Aspilota ulmicola. After revision of the holotype we consider it to belong within the genus Synaldis by the absence of vein 2-SR.
