Diagnosis. This genus can be distinguished from other genera of Ophioninae by the following combination of character states: (1) mandible not twisted, barely tapered, with symmetric teeth or upper tooth slightly longer than lower one, usually with a swelling and oblique groove on its basal surface ( Figs 1 View FIGURES 1 – 4 , 8, 10 View FIGURES 8 – 14 , 16, 18 View FIGURES 16 – 22 , 25, 27 View FIGURES 25 – 31 ); (2) in lateral view, clypeus strongly convex, its lower part abruptly strongly curved backward ( Figs 10 View FIGURES 8 – 14 , 18 View FIGURES 16 – 22 , 27 View FIGURES 25 – 31 ) and in frontal profile its lower margin nearly straight ( Figs 1 View FIGURES 1 – 4 , 8 View FIGURES 8 – 14 , 16 View FIGURES 16 – 22 , 25 View FIGURES 25 – 31 ); (3) occipital carina complete except for lower end absent and not joined to hypostomal carina and base of mandible ( Figs 9, 10 View FIGURES 8 – 14 , 17, 18 View FIGURES 16 – 22 , 26, 27 View FIGURES 25 – 31 ); (4) ocelli large and posterior ones adjacent with eyes ( Figs 1 View FIGURES 1 – 4 , 8–10 View FIGURES 8 – 14 , 16–18 View FIGURES 16 – 22 , 25–27 View FIGURES 25 – 31 ); (5) posterior transverse carina on mesosternum complete, rarely interrupted in a few Australasian species (i.e., L. anici Gauld, 1977 , and L. antennatus (Morley, 1912)) ; (6) notauli faintly present as vestiges or completely absent ( Figs 11 View FIGURES 8 – 14 , 19 View FIGURES 16 – 22 , 28 View FIGURES 25 – 31 ); (7) epicnemial carina on mesopleuron present and its upper end reaching above level of lower margin of pronotum ( Figs 11 View FIGURES 8 – 14 , 19 View FIGURES 16 – 22 , 28 View FIGURES 25 – 31 ); (8) anterior transverse carina on propodeum developed but in a few species its outer end absent ( Figs 11, 12 View FIGURES 8 – 14 , 19, 20 View FIGURES 16 – 22 , 28, 29 View FIGURES 25 – 31 ); (9) posterior transverse carina on propodeum virtually absent but often with vestiges laterally ( Figs 11, 12 View FIGURES 8 – 14 , 19, 20 View FIGURES 16 – 22 , 28, 29 View FIGURES 25 – 31 ); (10) fore wing with a glabrous area on anterior corner of discosubmarginal cell, and virtually all species without sclerites there, except for a Filipino species, L. pterospilus Gauld & Mitchell, 1981 , which has a distinct sclerite; (11) 1m-cu on fore wing sinuous or curved, usually without ramellus ( Figs 2 View FIGURES 1 – 4 , 32–34 View FIGURES 32 – 34 ); (12) hind wing usually with an apparently elongated penultimate hamulus on R1 ( Fig. 13 View FIGURES 8 – 14 ), while occasionally with uniform hamuli ( Figs 21 View FIGURES 16 – 22 , 30 View FIGURES 25 – 31 ); (13) tibial spur of fore leg without a membranous flange; (14) mid and hind trochanters simple; and (15) distal pecten of hind tarsal claw developed and significantly longer than true apex of claw ( Figs 14 View FIGURES 8 – 14 , 22 View FIGURES 16 – 22 , 31 View FIGURES 25 – 31 ).
Distribution. Australasian, Oceanic, Oriental, and Palaearctic regions ( Gauld 1977; Gauld & Mitchell 1981; Shimizu & Watanabe 2015a).
Bionomics. Host is unknown. Adult wasps are often collected in LT in rainforests.
Remarks. Most Leptophion species are known from the Australasian region while only a few species are distributed in the Oceanic and Oriental regions and the southeastern part of the Palaearctic region.
In Taiwan, three species (i.e., L. maculipennis of the maculipennis species-complex, and L. radiatus and L. giganteus Shimizu & Watanabe , sp. nov., both of which belong to the radiatus species-complex) are found ( Gauld & Mitchell 1981; Shimizu & Watanabe 2015a, b) and they can easily be distinguished from each other by the following key.
