Remarks

Loboscelidia vang sp. nov. resembles L. collaris Fouts, 1922 in having the following characteristics: yellowish brown body color; basal part of cervical expansion strongly constricted in dorsal view; and carinated dorso-lateral surface of pronotum. However, it can be distinguished by the following characteristics: rectangular frontal projection (triangular in L. collaris ); scape more than 3.5 times as long as wide (less than 3.0 times as long as wide in L. collaris ); F1 and F2 less than twice as long as wide (more than twice as long as wide in L. collaris ); temple longer than MOD (shorter than MOD in L. collaris ); and straight M vein (curved in L. collaris ).
