Remarks

Loboscelidia glabra sp. nov. resembles L. antennata Fouts, 1922 and L. hei Yao, Liu & Xu, 2010 ; however, L. glabra sp. nov. has eyes without setae (with erect setae in L. antennata ); pronotum 0.80 times as long as wide (0.60 times as long as wide in L. antennata ); shorter F11 0.80 times as long as wide (1.2 times as long as wide in L. hei ); and a narrow hindtibial flange, 0.80 times as wide as the tubular part (as wide as the tubular part in L. hei ).
