discussion
Remarks Loboscelidia cucphuongensis sp. nov. resembles L. cuneata sp. nov., L. maai (Lin, 1964), L. nitidula Kimsey, 2012 and L. pallarela sp. nov. in having a parallel cervical expansion. However, L. cuchphuongensis sp. nov. can be distinguished by the following characteristics: forefemur bearing simple setae (with cuneate setae in L. cuneata sp. nov.); R 1 less than 0.5 times as long as R (more than 0.5 times as long as R in other four species); cu-a less than 0.5 times as long as R (as long as R in L. maai and L. nitidula); and Rs about 2.5 times as long as R (more than 3. 0 times as long as R in L. nitidula and L. pallalela sp. nov.).
