Bracon (Synodus) incompletus Ratzeburg.

Diagnosis.

Small to moderate size, 1.5-3.5 mm; occipital carina not meeting hypostomal carina; fore tibia with single row of small spines; hind coxa with distinct antero-ventral basal tooth; basal sternal plate (acrosternite) of metasomal segment 1 short, less than ¼ length of tergum; fore wing second submarginal cell elongated, vein 2RS absent, vein r-m present, first subdiscal cell closed at apex, vein 3CU on same line as vein 1CU; hind wing vein SC+R present, male without stigma in hind wing.

Distribution.

Australasian, Oriental, Palaearctic and Neotropical (new record).

Biology.

Species from Australia have been reared from Xylopsocus sp. ( Bostrichidae ) and Phoracantha sp. ( Cerambycidae ) ( Belokobylskij et al. 2004). No biological information is available for the species described below.

Comments.

Caenophanes is similar to Heterospilus by having the fore wing vein 2RS absent, but is distinct by having the fore wing first subdiscal cell closed at the apex. A key to species was presented by Belokobylskij and Maeto (2009).

One new species from Costa Rica is described below which is the first record for the genus in the Western Hemisphere.
