Deinodryinus, Perkins, 1907

Olmi, Massimo, 2023, Description of a new species of Deinodryinus from Ecuador: D. hubeni sp. nov. (Hymenoptera, Dryinidae), Zootaxa 5380 (1), pp. 96-100 : 97

The key to the males of the Neotropical Deinodryinus published by Olmi & Virla (2014) divides the species into two groups (see first couplet of the key to males), as follows:

1 Males with antennal setae shorter than breadth of antennomeres ( Fig. 1C )............................. 2 (first group)

– Males with antennal setae as long as, or much longer than breadth of antennomeres ( Fig. 1E )........... 10 (second group)

D. hubeni sp. nov. belongs to the first group, together with the following nine Neotropical species: D. albopictus Olmi, 1984 ; D. carpens Olmi, 1984 ; D. hansoni Olmi, 1991 ; D. irwini Olmi, 1991 ; D. nigrorufus Olmi, 1984 ; D. perlucens Olmi, 1984 ; D. pseudobilobus Olmi, 1984 ; D. sculptus Olmi, 1995 ; D. vagans Olmi, 1984 . Because of the face sculptured by longitudinal keels ( Fig. 1C ) and the paramere with a large inner branch wrapping the penis ( Fig. 2B ), the new species is similar to D. albopictus , D. carpens , D. perlucens , D. pseudobilobus and D. sculptus ( Figs 2A, C–F ). However, in D. hubeni the inner branch of the paramere is long, narrow and situated in proximal position ( Fig. 2B ), whereas in the other species it is short, broad and situated in distal or subdistal position ( Figs 2A, C–F ).
