Diagnostic description. Mesosoma entirely to mostly dark (dark brown or black), lighter areas very small and localized; metasoma dorsally entirely dark (brown or black); gena without pale spot or with very small, almost indistinguishable spot; tegula pale; first two pairs of legs entirely pale (yellow, orange or light yellow-brown), rarely with coxae darker; metacoxa pale; metafemur mostly pale (yellow, orange or light yellow-brown); metatibia mostly yellow; T 2 mostly sculptured. See Table 1 for additional morphological measurements. Notogaster withersae is morphologically similar to N. poultonae, both species can be distinguished from all other Notogaster species based on the combination of mesosoma and metasoma being mostly to entirely dark brown to black while legs are entirely to mostly yellow, and gena not having a pale spot at base (or, at most, with a very small and poorly defined spot, almost indistinguishable from rest of gena). Notogaster withersae has metacoxa entirely yellow (mostly brown in N. poultonae), fore wing vein 1CUb only slightly longer (1.3 ×) than 1CUa (in N. poultonae 1Cub is much longer (2.0–3.0 ×) than 1CUa), and T 2 comparatively more transverse, its width at posterior margin 2.6–2.8 × its median length (in N. poultonae T 2 it is more quadrate, with width at posterior margin 1.6–2.2 × its median length).

Molecular data. There are no DNA barcode sequences in BOLD for this species.
