Diagnosis. FEMALE. This is the only Southeast Asian genus to have T1 elongate and petiolate. Additional useful features include the swollen mesonotum, the absence of a felt line on T2, the presence of a felt line on S2, and T6 lacking a defined pygidium. Other useful characters are mentioned in Lelej (1996b). MALE. See Lelej (1996b).

Diversity and Distribution. Eleven species are known. This genus is widespread in the Oriental region ( Lelej 2005; Zhou et al. 2018a) and two of the species reach the Palaearctic region in China ( Lelej 2002).

Remarks. Although O. vietnamica is the only species recorded from Thailand, the following species from surrounding countries are likely to be discovered there, eventually: O. chinensis ( Zavattari, 1922) , O. desponsa ( Smith, 1855) , O. krombeini Lelej, 1996 , and O. sejugoides ( Magretti, 1892) .
