Remarks

Loboscelidia cuneata sp. nov. resembles L. cucphuongensis sp. nov., L. laminata and L. parallela sp. nov. in having the following characteristics: reddish brown body color; weakly convex cervical expansion in lateral view; basal part of cervical expansion parallel in dorsal view ( L. cucphuongensis sp. nov. and L. parallela sp. nov.); curved M vein; and Rs 3.0 times as long as R. However, L. do sp. nov. can be distinguished by the following characteristics: scape more than 3.0 times as long as wide (much less than 3.0 times as long as wide in L. do sp. nov. and L. laminata ); scape with longitudinal grooves (smooth in L. do sp. nov. and L. laminata ); L. cuneata sp. nov. has cuneate setae on the forefemur and all tibiae (simple setae in other species); R1 as long as R (much shorter than R in other three species); and scutellum rugose and punctured surface (polished and almost impunctured in L. parallela sp. nov. and L. do sp. nov.).
