Odontepyris costatus sp. nov. is described from Japan and Taiwan. This new species is most similar to O. formosicola Terayama, 1997 known from Cambodia and Taiwan according to the key to the Eastern Palaearctic Odontepyris. O. costatus sp. nov. can be distinguished from the latter by the relatively small eye and the wide metapectal-propodeal disc. It is also similar to O. telortis Lim & Lee, 2009 known from South Korea, but it is distinguished from O. telortis by the imbricate median area of metapostnotum. The morphological variations and diagnostic characters of the Eastern Palaearctic species are briefly discussed and the modified key to species is provided. Key words: new species, Japan, Taiwan, wing venation

Comments. This new species is similar to O. cynpus sp. nov. because both species have the arched anterior margin of pronotal disc, the basal vein with short stub (Rs+M) and the propodeal disc with discal carina incomplete. However O. escus sp. nov. has the head as long as wide, the vertex crest almost straight, the prostigma large and the propodeal disc with the space between median and discal carinae flat and imbricate, whereas O. cynpus sp. nov. has the head wider than long, the vertex crest strongly concave, the prostigma narrow and the propodeal disc with the space between the median and discal carinae depressed, imbricate and rugulose., Published as part of Alencar, Isabel D.

This is the most abundantly collected species of Odontepyris in Madagascar. This species is unique in having the female hypopygium elevated posteriorly and puncticulate. Odontepyris bedus sp. nov. is similar to O. marishi Terayama 1999 from Ryukyus because both species have the pronotal disc with the anterior margin straight and lateral margins angulate, the scutellar groove scrobiculate, the discoidal cell absent and the pterostigma large. However O. marishi has a very short stub of vein arising from the posterior of the Rs vein and the discal carina of the propodeal disc is arched (Terayama 1999: 105, fig. 16), whereas O. bedus sp. nov. has the stub vein absent and the posterior carina of propodeal disc converging posterad in a diagonal line. The only five Odontepyris males collected in Madagascar were sex associated to females of O. bedus sp. nov. because they share many features such as: the vertex crest concave, the wings with 2 / 3 anterior portion narrower than in other Madagascar species, the Rs+M short, the scutellar groove trabeculate, the pronotal disc smooth and the propodeal disc with median and discal carinae incomplete. From 34 known species in Odontepyris, there are eight with male-female association and just one is known only by male specimens. The male-female associations are rare to Odontepyris since males are rarely collected with Malaise trap., Published as part of Alencar, Isabel D. C.

The combination of the absence of the scutellar groove and the presence of the polished triangular area in the anterior part of the median propodeal carina in this species is unique in Odontepyris. Individually these characters are found in other Odontepyris, but not combined in one species. Odontepyris acrius sp. nov. also differs from other Malagasy species by having the frons shining, the ocellar triangle with an obtuse frontal angle and the discoidal cell present, whereas all other species studied from Madagascar have the frons opaque, the ocellar triangle with an acute frontal angle and the discoidal cell absent. Other significant features are the flagellomeres with erect pubescence and the absence of placoid sensillae, whereas the flagellomeres of other Malagasy species have the pubescence appressed or subappressed and placoid sensillae present., Published as part of Alencar, Isabel D.

Biology (Figs. 8���13). An alate female wasp was observed laying nineteen elongate oval eggs on the larva of Telorta divergens (Butler) on the leaf of Magnolia sp. (Magnoliales: Magnoliacea) (Figs. 8���10) (14.vi. 2008). In three days, nine young ectoparasitoid larvae hatched on the skin of the host caterpillar (17.vi. 2008). Two days later, the fully grown larvae were found (ca. 4.5mm long, ca. 1.5mm wide; purple with many small white spots, dorsum with longitudinal smooth area). Among the nine larvae, three (males) were distinctly smaller than the others (Fig. 11) (19.vi. 2008). One day later, all mature larvae pupated in the cocoons, apart from the host larva (Fig. 12) (20.vi. 2008). Maternal care of the parent wasp was observed until the pupation of the offspring. The parent wasp was dead on 27.vi. 2008, thirteen days after her oviposition. M a t e r i a l e x a m i n e d.

This species is similar to O. ovatus Xu and He, 2006 from China by 'legs black except brown trochanters, tibiae and tarsi; forewing with an ellipsoidal areolet; scutellar pits separated by about 4.0X as long as wide; a pair of paramedian discal carinae on propodeal disc conversing posteriorly'. However, it is distinguished from the latter by 'mandible reddish brown (black in O. ovatus); third antennal segment relatively short, 1.7 X as long as wide (2.2 X as long as wide in O. ovatus); median clypeus broad (very narrow in O. ovatus); paramedian discal carinae on propodeal disc extending only 7 / 10 of length of disc (extending nearly transverse carina in O. ovatus); propodeal disc 0.5 X as long as wide (0.64 X as long as wide in O. ovatus)'. Discussion. The members of Odontepyris have been known as the ectoparasitoids of lepidopteran larvae (Kurian, 1954, 1955; Georgiev et al., 2001), however, the relationship between bethylid wasp and host insect are poorly known. According to our observation, the female wasp laid multiple eggs on the skin of fully grown caterpillar of a noctuid host, Telorta divergens, and the ectoparasitic larvae grow very fast and pupated in three days after hatching. Further studies on its host ranges and life cycle are requisite. Etymology.
