Type species.

Dinotrema erythropum Foerster, 1863 , by original designation (Figs 14 , 15 ).

Material examined

( Dinotrema (Dinotrema) erythropum ): England: • 1 female (paratype of Aspilota praecipua ) and 1 male (paratype id.), Coll. Marshall Cornwall, Botusfleming ( HNHM) . Denmark: • 1 female, E-Jylland, Frisenborg , 28. vii. 1986 (Munk leg.) ( NMA) . Finland: • 1 female, Sa. Valkeala , 6772: 483, 28. vii. 1977 (Koponen leg.) ( NMA) ; • 1 female, same locality but, 29. vii. 1977 ( NMA) . Hungary: • 1 female, Ugod, Somberek Hubertlak-Kórnyéle , 26–29. vi. 1967 (Papp leg.) ( HNHM) . Luxembourg: • 2 females, Tratten, b. Murau Stmk . Coll Fulmek, 14. viii. 1942 and 13. x. 1954 ( NHMW) . Netherlands: • 1 female, Wijster (Dr.) opposite Biological Station , 22–30. ix. 1975 (van Achterberg leg.) ( RMNH) . Spain: • 1 female, Valencia, 16. vii. 1942 ( NHMW) .

Diagnosis.

The main diagnostic characters of this subgenus are the short paraclypeal fovea which remain far from the eye margins, the pterostigma very narrow (linear) and vein 2 - SR of fore wing present and more or less completely sclerotised.

Remarks.

This is the largest subgenus including the main part of Dinotrema species with approx. 440 species described worldwide (Peris-Felipo and Belokobyslkij 2018 a). As shown by van Achterberg and Vikberg (2014), Pterusa Fischer, 1958 is a synonym of Dinotrema sensu stricto, because any differences are absent in females, and it is based only on the brachyptery of the males.
