Identification key to British and Irish species of Enicospilus 

1. Fore wing lacking sclerites in glabrous area of discosubmarginal cell ( Fig. 2 AView Fig); large species, wing length c. 20 mm ................................................................................................................................. 2

– Fore wing with at least one discrete sclerite in discosubmarginal cell ( Fig. 2View Fig B–D); smaller species, wing length <15 mm ......................................................................................................................... 3

2. Head posteriorly, in dorsal view, not expanded laterally beyond the eyes; ocelli touching or almost touching eye; antennal socket separated from inner margin of eye by not more than a third socket diameter ( Fig. 3AView Fig) ................................................................ Enicospilus inflexus ( Ratzeburg, 1844) 

– Head posteriorly, in dorsal view, expanded so that head is wider than its width at the eyes; ocelli distinctly separated from eye by about 0.2 × diameter of ocellus; antennal socket separated from inner margin of eye by about half socket diameter ( Fig. 3 BView Fig) .............................................................. ....................................................................................... Enicospilus undulatus ( Gravenhorst, 1829) 

3. Fore wing with distinct, pigmented proximal and central sclerites ( Fig. 2 BView Fig) ................................... 4

– Fore wing with distinct, pigmented proximal sclerite: central sclerite may be present but translucent ( Fig. 2View Fig C–D)........................................................................................................................................ 8

4. Pronotum, mesopleuron, mesoscutum and propodeum with dark patches ( Fig. 14 AView Fig)........................ ...................................................................................... Enicospilus combustus ( Gravenhorst, 1829) 

– Mesosoma lacking dark patches, uniformly testaceous..................................................................... 5

5. Metasoma abruptly tipped with black posteriorly, from 5 th or 6 th tergite ( Fig. 14 BView Fig)........................... ............................................................................................ Enicospilus ramidulus ( Linnaeus, 1758) 

– Metasoma not abruptly black-tipped (but may be diffusely infuscate ventrally and apically).......... 6

6. Head with temples rounded, more buccate, and with distinct ocular-ocellar space ( Fig. 4 CView Fig); first metasomal tergite in lateral view with better-defined dorsal dip ( Fig. 6 CView Fig); male aedeagus apically paler, apex more rounded, protruding more dorsally and not reflexed ventrally ( Fig. 9 BView Fig)................. ............................................................................................................... Enicospilus myricae  sp. nov.

– Head with temples narrowed, straighter, with ocelli adjacent to or only narrowly separated from eyes ( Fig. 4View Fig A–B); first metasomal tergite with shallow dorsal dip ( Fig. 6View Fig A–B); male aedeagus same colour throughout, apex more smoothly curved, not so protruding dorsally, reflexed ventrally ( Fig. 9 AView Fig) .. 7

7. Temples very strongly narrowed behind eyes ( Fig. 4 AView Fig); scutellum with sides more nearly parallel, heavily punctate and with slight posterior ridge ( Fig. 5 AView Fig); antenna with 51–56 flagellar segments, preapical flagellar segments stouter ( Fig. 7 BView Fig) .......................... Enicospilus cerebrator Aubert, 1966 

– Temples less strongly narrowed posteriorly ( Fig. 4 BView Fig); scutellum with sides distinctly converging posteriorly, more sparsely punctate and smoothly curved posteriorly ( Fig. 5 BView Fig); antenna with 58–69 flagellar segments, preapical flagellar segments slenderer ( Fig. 7 AView Fig) .................................................. .......................................................................................
