Revision of the Western Palaearctic species of the genus Dinotrema Foerster, 1862 (Hymenoptera, Braconidae, Alysiinae)

Abstract

The first comprehensive revision of the Western Palaearctic species of the genus Dinotrema Foerster, 1862 is provided. 174 species of this genus are redescribed and illustrated. Ten species are described as new, viz, D. acompressum sp. nov., D. cahitum sp. nov., D. collybiae sp. nov., D. digitatum sp. nov., D. glabrideum sp. nov., D. helote sp. nov., D. lepiotae sp. nov., D. norwegicum sp. nov., D. oxybellum sp. nov. and D. torpi sp. nov. The following new combinations are suggested: Dinotrema adventum (Fischer), comb. nov., D. aurelianum (Fischer), comb. nov., D. cetiusmonte (Fischer), comb. nov., D. converginerve (Fischer), comb. nov., D. intermissum (Fischer), comb. nov., D. leptocorne (Fischer), comb. nov., D. longicarinatum (Fischer), comb. nov., and D. thurnense (Fischer), comb. nov. The following names are synonymised: Dinotrema naeviformis (Fischer) with D. costulatum (Thomson), Dinotrema aequale Tobias with D. tarbagataicum Tobias, D. alua (Stelfox et Graham) with D. tauricum (Telenga), D. isometricum (Fischer) with D. cruciatum (Fischer), D. isosoma (Fischer) with D. cruciforme (Fischer), and D. ovalisignum (Fischer) with D. catharinae (Fischer) (syn. nov.). A key to all Western Palaearctic species of Dinotrema is provided for the first time.

Dinotrema cavernicola sp. n. (Hymenoptera, Braconidae, Alysiinae), a new species of the genus Dinotrema Foerster from caves of Spain

“…Comparative diagnosis. According to the key by Peris-Felipo et al (2014), this new species is similar to D. affine (Fischer, 1973) Remarks. Specimens belonging to the families Phoridae and Heleomyzidae (Diptera) were captured in the same traps as Dinotrema cavernicola sp.…”

“…To follow the identification keys by Peris-Felipo et al (2014), the following differences in terminology should be kept in mind (terms in Peris-Felipo et al (2014) Type specimens are deposited in the Entomological Collection at the University of Valencia (Valencia, Spain; ENV), in the Grupo de Espeleología de Villacarillo (Jaén, Spain; GEV), and in the Zoological Institute RAS (St Petersburg, Russia; ZISP). Description.…”

“…It comprises many dozens of species described from the Palaearctic Region and mainly from Western Europe (Fischer 1972;van Achterberg 1988;Tobias 2003Tobias , 2004aTobias , 2004bTobias , 2006, but numerous Palaearctic species remain as yet unknown. Increasing our knowledge of this genus, several papers have been published by the two first authors (Peris-Felipo and Belokobylskij 2013;Peris-Felipo et al 2013a, 2013b, 2013c, 2013d, 2014) and a monograph with a revision of the Western Palaearctic Dinotrema species will be published soon (Peris-Felipo et al 2014). An arrangement of Dinotrema species in morphological groups was suggested by Fischer (1972) and later, on the basis of more diverse material, further developed by Tobias (2003Tobias ( , 2004aTobias ( , 2006.…”

Catalogue of Danish Alysiinae (Hymenoptera: Braconidae), with the description of two new species of Aspilota Foerster, 1863

“…They are koinobiont endoparasitoids of Diptera-Cyclorrapha (Gimeno et al 1997;Zaldivar-Riverón et al 2006;Peris-Felipo et al 2014a); records of some species of Hymenoptera and Lepidoptera as hosts (Yu et al 2012) are most probably erroneous. Some alysiine species can be relevant from an economic point of view due to their potential role in pest control (González et al 2000;Elpino-Campos et al 2007).…”

“…The subfamily is divided into two large and polymorphic tribes, the Alysiini and Dacnusini (Shenefelt 1974;Yu et al 2012). Morphologically, these two tribes are mainly separated by the presence (Alysiini) or absence (Dacnusini) of the fore wing vein cuqu2 (r-m or second radiomedial); accordingly, Alysiini has two submarginal (radiomedial) cells while Dacnusini has only one cell (Shenefelt 1974;Yu et al 2012;Peris-Felipo et al 2014a). Members of the tribe Alysiini are common parasitoids of Diptera-Cyclorrapha, usually inhabiting humid and ephemeral substrates.…”
