Xanthocampoplex Morley, 1913

Xanthocampoplex Morley, 1913: 445 . Type: Xanthocampoplex orientalis Morley, 1913 (= nigromaculatus Cameron, 1907 ). Original designation.

Diagnosis. The character states of this genus described by Townes (1970) and Gupta (1973). This genus can be distinguished from other genera by the following combination of character states: clypeus without a weak convexity at centre, its apical margin thin and narrowly reflexed; lower tooth of mandible not longer than upper tooth; inner margin of eye not notched opposite antennal socket; flagellum covered with short setae and with an erect, short seta on apex of ventral surface ( Fig. 16 ); some apical flagellomeres as long as wide or wider than long; propleuron without a forward projecting flange; mesopleuron largely mat ( Fig. 26 ); posterior transverse carina of mesosternum complete ( Fig. 28 ); propodeum nor quite elongate and very short ( Figs 23, 27, 29 ); propodeal spiracle circular to elliptic; areolet usually present, receiving second recurrent vein distad of the middle; nervulus opposite basal vein, or distad of it by less than 0.3 its length; nervellus vertical or subvertical, not intercepted; discoidella not pigmented or absent; hind first tarsomere with a continuous, straight, median ventral row of very closely spaced small hairs ( Figs 18–20 ); tarsal claws small to moderate length and pectinate ( Figs 18, 21 ); glymma small, obsolescent or sometimes absent; ovipositor 1.0–2.2 × as long as hind tibia; apex of dorsal valve of ovipositor without a distinct convexity ( Fig. 22 ); body usually with large yellow areas ( Figs 23–29 ).

Distribution. Afrotropical, Australasian, Eastern Palearctic, Nearctic, Oceanic and Oriental regions.

Bionomics. Two families, Crambidae and Cossidae (Lepidoptera) ( Gupta, 1973; Haeselbarth, 1983), have been recorded as the host while no record is known in Japan.

Remarks. I newly recorded this genus from Eastern Palearctic region based on Japanese materials of X. chinensis below.
