Remarks

Loboscelidia cilia sp. nov. resembles L. reducta and L. cinnamonea Kimsey, 2012 in having the following characteristics: strongly convex cervical expansion, with transverse carina behind ocelii, without tibial flanges. However, L. cilia sp. nov. can be distinguished by the following characteristers: erect setae on the eye (without setae in the other two species); complete M vein (absent in L. reducta ); and cu-a and R1 present (cu-a absent in the other two species, R1 absent in L. cinnamonea ).
