Oxyscelio crebritas

<p>This species is widespread through southeast Asia, extending to Nepal in the northwest and Sulawesi and Taiwan in the east. The new data provide an additional record for Taiwan and documents the presence of the species in Hainan. Link to dynamic distribution map: <a>http://hol.osu.edu/map-large.html?id=275371</a></p>
