Male. Similar as female.
Distribution. India (Rajasthan).
Host. Unknown.
Etymology. The species is named after the smooth and shiny fifth metasomal tergite; “ nitidus ” is Latin for shining.
Comparative diagnosis. The new species is similar to Rhadinobracon zarudnyi and R. levigatus sp. nov. in having the basal half of fore wing largely subhyaline, but it differs from the latter species in having a smooth fifth metasomal tergite. Additionally, the new species comes closer to R. zarudnyi in having the medio-basal area of the second metasomal tergite striate. However, R. striata differs from R. zarudnyi in having the following differences: head only black dorsally (vs completely black in R. zarudnyi ), medio-basal area of second metasomal tergite more than 0.5 × as long as tergite (vs less than 0.5 × in R. zarudnyi ) and second metasomal tergite completely yellow (vs with black marks in R. zarudnyi ).
