Type species.

Dinotrema erythropa Foerster, 1863 , by monotypy.

Diagnosis.

Mandible small, simple, tridentate, often with upper (first) tooth diminished with respect to lower (third) tooth. Paraclypeal fovea short, not reaching more than half distance between clypeus and inner margin of eyes. Mesoscutum with or without mesoscutal pit; notauli usually present only in anterior part of mesoscutum, although in some species of the subgenus Alitha it is rather well developed and reaching or almost reaching mesoscutal pit; precoxal sulcus usually present, propodeum with different types of sculpture and sometimes with longitudinal and / or transverse carinae, rarely entirely smooth. In fore wing, marginal cell never shortened; vein r originating from basal quarter of pterostigma; vein 2 - SR usually present and distinctly sclerotised or sometimes (subgenus Synaldis ) absent or weakly developed and vein r not angled with vein 3 - SR ( van Achterberg 1988); veins m-cu and cu-a postfurcal; first subdiscal cell always closed postero-apically by CU 1 a vein. Venation of hind wing more or less reduced, sometimes without closed cells ( Zhu et al. 2017). Metasoma of ♀ more or less distinctly compressed laterally. Ovipositor sheath usually not longer than metasoma.

Remarks.

Dinotrema is the most complicated and largest genus within the tribe Alysiini with more than 440 known species, predominantly occurring in the temperate climatic regions (Peris-Felipo and Belokobyslkij 2018 a). However, after studying a large amount of type material from different regions it should be possible to present a new generic classification, including the following subgenera: Alitha Cameron, 1906 , stat. nov. (with Carinthilota Fischer as a new synonym), Dinotrema sensu stricto, Prosapha Foerster, 1863 , Pseudoprosapha Peris-Felipo subgen. nov. and Synaldis Foerster, 1863 (with Eudinostigma Tobias as a new synonym).

A revision of Eudinostigma Tobias species was carried out for this reclassification. After careful study of the type species of Eudinostigma we consider it a synonym of Dinotrema . However, depending on the presence or absence of vein 2 - SR of the fore wing, its species are divided between the subgenera Dinotrema and Synaldis . The main diagnostic characters of Eudinostigma are as follows: distinctly depressed head (resulting in antennal sockets situated at the upper level of eye and maximum width of head in dorsal view 1.6–2.4 × width of mesoscutum), compressed mesosoma, and vein 2 - SR of fore wing often absent ( Tobias 1986; van Achterberg 1988). These characters also occur sometimes in Dinotrema species, e. g., among others, in Dinotrema brevissimicorne (Stelfox et Graham, 1948) , D. compressum (Haliday, 1838) , D. parapunctatum ( Fischer, 1976) , and D. robertoi Peris-Felipo, 2013 .

The following species previously belonging to Eudinostigma are transfered to the subgenus Dinotrema sensu stricto: D. (D.) alox ( van Achterberg, 1988) , comb. nov.; D. (D.) entabeniense (Fischer, 2009) , comb. nov.; D. (D.) latum ( Chen & Wu, 1994) , comb. nov.; D. (D.) planiceps ( Fischer, Tormos & Pardo, 2006) , comb. nov. and D. (D.) subpulvinatum (Fischer, 2009) , comb. nov.. Moreover, four other Eudinostigma species are transferred to the subgenus Synaldis : D. (S.) bienesae ( Fischer, Tormos & Pardo, 2006) , comb. nov., D. (S.) fischeri ( Tobias, 1986) , comb. nov. (type species of Eudinostigma ), D. (S.) latistigma ( Fischer, 1962) , comb. nov., and D. (S.) planiceps ( Fischer, Tormos & Pardo, 2006) , comb. nov.

Furthermore, after studying the types of Dinostigma and Eudinostigma species, we consider the features of Eudinostigma stenosoma van Achterberg, 1988 (see below) enough different to transfer it to a new subgenus Pseudoprosapha subgen. nov.: Dinotrema (Pseudoprosapha) stenosoma ( van Achterberg, 1988) , comb. nov.

In summary, five subgenera of the genus Dinotrema are recognised, Alitha Cameron, 1906 , stat. nov., Dinotrema sensu stricto, Prosapha Foerster, 1863 , Pseudoprosapha Peris-Felipo subgen. nov. and Synaldis Foerster, 1863 .
