Anisocyrta Foerster, 1863: 268 .

Type species: Alysia perdita Haliday, 1838: 241 (mOnObasic).

Diagnosis. Head sub-cubical to transverse ( Figs 5 , 14 ); antenna medium-sized to long, with 24–40 flagellomeres ( Figs 1 , 11 ); F1 1.40–2.20 × longer than F2; mandible large, setiferous, with fourth lamelliform protuberance ventrally ( Figs 3, 4 , 12 ), the protuberance may be divided into two small teeth, e.g., A. alpinicola (van Achterberg 1986: fig. 16), and third tooth distinctly developed, diagonal ridge weak; clypeus moderately large, somewhat protruding; anterior tentorial pits medium-sized ( Fig. 3 ); maxillary and labial palp with 6 and 4 palpomeres, respectively; pronope absent, pronotum only with transverse groove; precoxal sulcus absent ( Fig. 7 ) or present only as smooth groove ( Fig. 15 ); scutellum low, rounded, never with posterior spine; metanotum with tall medial carina which may be protruding ( Figs 7 , 16 ); propodeal spiracle small; propodeum with complete mid-longitudinal carina ( Figs 8 , 18 ), antero-dorsal part of propodeum not differentiated from postero-dorsal part except by curve midlongitudinal carina ( Figs 9 , 16 ); fore wing venation complete; pterostigma linear or nearly so, its length about 10.00 × its width ( Figs 1 , 11 ); vein r of fore wing arising from base of pterostigma ( Figs 1 , 11 ) except in A. curticubita and Anisocyrta masoni Wharton (van Achterberg 1986: Figs 19 , 31); vein 3RSa of fore wing longer than vein 2RS; vein 1m-cu of fore wing interstitial (van Achterberg 1986: fig. 4) to postfurcal ( Figs 1 , 11 ); first subdiscal cell of fore wing closed; vein 2cu-a of fore wing subequal to 2CUa or slightly longer ( Figs 1 , 11 ); vein cu-a of hind wing present; vein 1M of hind wing shorter than or equal to vein M+CU ( Figs 1 , 11 ); dorsope present; laterope absent ( Figs 8 , 19 ); T2 smooth; ovipositor sheath setiferous and with apical spine (van Achterberg 1986: fig. 1); length of ovipositor sheath 1.40–4.00 × length of hind tibia, usually 0.50–0.80 × fore wing (except A. masoni ).

Distribution. Nearctic, Palearctic, and Oriental regions ( Yu et al. 2016).

Biology. Anisocyrta perdita : reared with Pegomya scapularis and Pegomya circumpolaris ex Leccinum scabrum ( Yakovlev & Tobias 1992) ; collected from Leucopaxillus giganteus ( Koponen 2000) .
