Allophrys falcatus Reshchikov , sp. nov. ( Figs 10–18 )

Diagnosis. This species is easily distinguished from other Oriental species of the genus by flagellomeres elongate to subquadrate ( Fig. 18 ), notauli deeply impressed and complete, scutellar groove with longitudinal median carina ( Fig. 12 ), foveate groove of mesopleuron well developed, over entire mesopleuron ( Fig. 16 ), propodeal spiracle round, separated from pleural carina by 2.0× diameter of spiracle, and ovipositor curved downwards ( Fig. 17 ).

Description. Female. Body length 1.95 mm. Forewing length 1.22 mm.

Mandible with upper tooth distinctly longer than lower tooth ( Figs 10, 11 ). Clypeus 2.0× as broad as long, with fine and sparse punctures ( Fig. 10 ). Malar space 0.7 × basal width of mandible ( Fig. 11 ). Flagellum of antenna with 22 flagellomeres, moderately slender, second flagellomere 2.6× and subapical flagellomere rather elongate, 3.0× as long as broad ( Fig. 18 ). Face, frons and vertex smooth, shining ( Figs 10, 11, 13 ). Compound eyes very large, convergent above antennae, setose ( Figs 10, 11, 13 ). Occipital carina mediodorsally absent.

Mesosoma smooth and impunctate, shining. Notauli deeply impressed and complete. Scutellar groove with longitudinal median carina ( Fig. 12 ). Foveate groove of mesopleuron well developed, over entire mesopleuron ( Fig. 16 ). Propodeum with basal area neglected, ( Fig. 12 ), area superomedia pentagonal, 3.0× as long as broad ( Fig. 12 ). Propodeal spiracle separated from pleural carina by about 2.0 × diameter of spiracle ( Fig. 12 ). Apical area more or less impressed.

Forewing without 2-rm ( Fig. 14 ), without brachial cell ( Fig. 14 ). Hind wing with cu-a slanted about 85° from horizontal ( Fig. 15 ).

Legs moderately slender; hind femur 6.1× as long as broad.

First tergite 4.0× as long as posterior broad, its upper margin in lateral view ( Fig. 13 ) straight. Second tergite about 1.6× as long as anterior broad. Ovipositor curved downwards ( Fig. 17 ).

Etymology. This species name refers to falcatus , to reflect ovipositor shape.
