Remarks
Loboscelidia parallela sp. nov. resembles L. cuneata sp. nov. and L. halimunensis; however, it can be distinguished by the following characteristics: femora with simple setae (with cuneate setae in L. cuneata sp. nov.); flange of forefemur 0.85 times as wide as the tubular part (0.25 times as wide as the tubular part in L. cuneata sp. nov.); flange of foretibia 0.50 times as wide as the tubular part (1.5 times as wide as the tubular part in L. cuneata sp. nov.); and curved M vein (straight in L. halimunensis).
