Remarks.

, but smaller in size with shorter rostrum, hind femur not exceeding apex of abdomen, median vitta from head to apex of abdomen and not totally cinnamon in color.
Etymology.
The specific epithet ‘‘
luteus
’’ is a Latin noun meaning ‘‘yellow’’ and ‘‘
vittus
’’ from the Latin noun, ‘‘vitta,’’ meaning ‘‘longitudinal stripe.’’
