Watanabe, Kyohei & Taniwaki, Tooru, 2018, Taxonomic Study of the Genera Förster, 1850, and Cameron, 1903 (Hymenoptera, Ichneumonidae, Cryptinae) associated with (Hymenoptera, Tenthredinidae), with Description of a New Species, Bulletin of the Kanagawa Prefectural Museum (Natural Science) 47, pp. 73-84 : 79

Genus Javra Cameron, 1903

parviceps Cameron, 1903 ). Monobasic.

Finchra Cameron, 1907: 463 . Type species: Finchra gracilis Cameron, 1907 . Monobasic.

Monocryptus Hellén, 1957 (“1956”): 135. Type species: Cratocryptus opacus Thomson, 1873 . Monobasic.

Diagnosis. Townes (1970) proposed diagnosis of this genus. We refer it with some additional data of character states of Japanese species below. Mandible with two teeth, its upper tooth as long as or shorter than lower tooth. Flagellum slender ( Figs 4A , 5A ), F2 3.0–5.5 (female) or 2.7–4.0 (male) times as long as depth in lateral view. Apical half of flagellum not strongly flattened below, not strongly tapered to apex ( Figs 4A , 5A ). Propodeal spiracle not strongly elongate ( Fig. 5D ), at most 2.0 times as long as wide. Areolet pentagonal, rectangular, or quadrangular. T2 mat ( Fig. 4C ). Spiracle of T1 situated behind the mid-length ( Fig. 5C ). Ovipositor straight, its upper valve without oblique or transverse teeth ( Fig. 5E ). Clypeus ca. 0.5 times as long as wide in male.

Distribution. Holarctic and Oriental regions ( Yu et al., 2012).

Remarks. Two species, J. coreensis and J. teranishii (Uchida, 1952) , were previously recorded from Eastern Palaearctic region ( Yu et al., 2012). Japanese fauna of this genus is still poorly studied. We recognized eight species of this genus from Japan. Three of them are described species, J. coreensis , J. taniguchiae (Uchida, 1956) , and J. teranishii . In this study, we record J. coreensis from Japan for the first time, which was previously recorded as female of Javra sp. by Taniwaki & Watanabe (2012). The remainders may be undescribed or unrecorded species. Japanese species of this genus can be identified by the following key.

Javra Cameron, 1903: 47 . Type species: Javra parviceps Cameron, 1903 . Monobasic.

Cnemocryptus Cameron, 1903: 38 . Type species: Cnemocryptus validicornis Cameron, 1903 (= J avra
