Comments.

Macroteleia fugacious was described by Lê (2000) based on five females and three males. He stated the holotype (female) and four paratypes (two females and two males) were deposited in the Institute of Ecology and Biological Resources (IEBR). Two other paratypes are deposited in the Zoological Institute in St. Petersburg. However, the second author found that the holotype of Macroteleia fugacious is housed in the collection of the Zoological Institude in St. Petersburg. When examining the types of Lê’s species of Scelioninae in IEBR, the first author only found one female and one male specimens labeled as paratypes of Macroteleia fugacious . The two paratypes, unfortunately, are different species: the male paratype belongs to Macroteleia dolichopa , and the female paratype belongs to Macroteleia striativentris . We were unable to examine the holotype of Macroteleia fugacious in this study, and therefore the identity of Macroteleia fugacious is uncertain.
