Distribution.
Worldwide except Antarctica ( Yu et al. 2016).
Diagnosis.
Moderately to very large insects (fore wing length usually 9.0-30.0 mm).
Head: mandible bidentate apically and weakly to strongly tapered and twisted (e.g. Fig. 2A-D View Figure 2 ); ocelli moderately to very large, and posterior ocellus often close to or touching eye (e.g. Figs 3B-D View Figure 3 , 5B-D View Figure 5 , 7B-D View Figure 7 ); occipital carina complete; antennae longer than fore wing length (e.g. Figs 5A View Figure 5 , 12A View Figure 12 , 16A View Figure 16 ), usually with more than 50 flagellomeres.
Mesosoma: pronotum unspecialised; notauli almost always absent; scutellum with lateral longitudinal carinae usually along more than 0.8 × its length (e.g. Fig. 2E-H View Figure 2 ); epicnemial carina present laterally (e.g. Figs 5E View Figure 5 , 8E View Figure 8 , 18E View Figure 18 ); posterior transverse carina of mesosternum complete; propodeum with anterior transverse carina usually more or less complete medially, anterior area long and longitudinally striate.
Wings (e.g. Figs 1 View Figure 1 , 6F View Figure 6 , 7F View Figure 7 , 19F View Figure 19 , 28F View Figure 28 , 31B, D, F View Figure 31 ): pterostigma of fore wing fairly slender; vein 1m-cu&M of fore wing usually without ramulus; vein 2r&RS of fore wing usually more or less broadened proximally and/or centrally, straight, sinuous, or bowed, not proximally abruptly angled; discosubmarginal cell of fore wing with fenestra, and often also with one or more sclerites; vein RS of hind wing usually straight and rarely weakly curved; vein RA of hind wing usually with 4-12 uniform hamuli.
Legs: inner mesal surface of fore tibial spur without a membranous flange; outer distal margin of mid and hind trochantelli usually simple and without a decurved tooth; hind tarsal claw moderately to strongly curved with pectinae, usually all pecten are more or less uniform shape and length and a distal one is not significantly longer than true apex of claw (e.g. Fig. 2I, J View Figure 2 ).
Metasoma (e.g. Figs 3A View Figure 3 , 9A View Figure 9 ): very slender; tergite 1 with spiracle clearly far behind the middle; thyridium moderately to strongly developed, and oval to ellipsoidal; ovipositor straight and usually short, its length less than posterior depth of metasoma.
Colour: body usually entirely testaceous, pale yellow to reddish brown (e.g. Figs 4A-E View Figure 4 , 11A-E View Figure 11 , 21A-E View Figure 21 , 26A-E View Figure 26 ), sometimes posterior metasomal segments infuscate (e.g. Figs 9A View Figure 9 , 17A View Figure 17 , 18A View Figure 18 ); in some species body entirely brown to black, usually with testaceous to pale yellow patterns (e.g. Figs 5A-E View Figure 5 , 28A-E View Figure 28 ); wings entirely hyaline or weakly infuscate (e.g. Figs 3F View Figure 3 , 9F View Figure 9 , 10F View Figure 10 ), rarely with strong infumate patches (e.g. Figs 5F View Figure 5 , 28F View Figure 28 ); fenestra always hyaline (e.g. Figs 10F View Figure 10 , 19F View Figure 19 ); sclerites hyaline to black (e.g. Figs 18F View Figure 18 , 19F View Figure 19 , 23F View Figure 23 ).
Differential diagnosis.
Adult wasps of Enicospilus are moderately to very large insects and distinguished from other genera of Ophioninae by the following combination of character states: inner mesal surface of the fore tibial spur lacking a membranous flange; mandibles more or less narrowed apically and moderately to strongly twisted (e.g. Fig. 2A-D View Figure 2 ); fore wing discosubmarginal cell with a fenestra (e.g. Fig. 31B, D, F View Figure 31 ), extensive glabrous area, and often one or more sclerotised and pigmented sclerites and/or quadra (e.g. Figs 3F View Figure 3 , 15F View Figure 15 , 27F View Figure 27 ); posterior transverse carina of mesosternum complete.
The fore wing fenestra and sclerites are usually reliable characters for recognising Enicospilus species. However, similar sclerites of the fore wing fenestra are also known in the genus Dicamptus Szépligeti, 1905 and rarely in the genus Leptophion Cameron, 1901. Enicospilus species are distinguished from both Dicamptus and Leptophion by the mandibles (i.e. mandible always weakly to strongly tapered and twisted in Enicospilus , but very weakly tapered and not twisted in Dicamptus and Leptophion ).
Biology.
Species belonging to Enicospilus are koinobiont endoparasitoids of Lepidoptera, such as Noctuidae (e.g. Gauld and Mitchell 1981; Gauld 1985b, 1988; Broad and Shaw 2016; Broad et al. 2018). Adult female wasps usually lay eggs within late instar larvae of Lepidoptera, with some exceptions. Broad et al. (2018) summarised the biology of Ophioninae including Enicospilus . Both sexes of adults are very frequently attracted to the light and considered to be nocturnal or crepuscular (e.g. Shimizu and Maeto 2016; Shimizu 2017).
