discussion
Remarks Loboscelidia do sp. nov. resembles L. cuneata sp. nov., L. parallela sp. nov. and L. pecki Kimsey, 2012 in the following characteristics: reddish brown body color; rectangular frontal projection; F 1 and F 2 nearly twice as long as wide; transverse carina absent behind ocelli; flat ventral margin of the hindfemur. However, L. do sp. nov. can be distinguished by the following characteristics: frons with setae (L. cuneata sp. nov. without setae); scape less than 3.0 times as long as wide (more than 3.0 times as long as wide in other species); femora with simple setae (L. cuneata sp. nov. with cuneate setae); basal of cervical expansion weakly constricted (other two species parallel); R 1 vein less than 0.80 times as long as R (as long as R in L. pecki), and cu-a vein longer than 0.29 times as long as R (absent or slightly present in L. pecki).
