Remarks
Loboscelidia fulgens shares a completely lacking M vein with L. bakeri Fouts, 1922, L. guangxiensis Xu, Weng & He, 2006 and L. reducta. However, L. fulgens can be distinguished from the three species by the following characteristics: head wider than posterior width of pronotum (narrower than posterior width of pronotum in L. bakeri and L. reducta); R1 0.30 times as long as R (more than 0.50 times as long as R in L. guangxiensis); a flange on hindtibia more than 0.50 times as wide as tubular part of hindtibia (less wide than hindtibia in L. guangxiensis); well-developed tibial flanges (lacking in L. reducta); and propodeum without a transverse carina (with the carina in L. bakeri).
