Type species. Halys planus Fabricius, 1803, here designated.

Diagnosis. The genus was keyed and comprehensive diagnosis was provided by Linnavuori (1982: 67–68) as follows: ‘Body robust. Head parabolic; gena extending slightly beyond tylus, not recurved mesad apically, apex of tylus therefore not concealed. 2nd rostral joint much longer than 3rd and 4th joints together, 3rd joint tumid. Lateral margins of pronotum slightly curved or nearly straight, humeral angles rounded. Under surface of femora with small setigerous tubercles. Scent gland orifices (Fig. 86f) very small, evaporatoria large, opaque, ± punctate. Male genitalia: Pygofer robust; ventral surface usually with ± distinct setose medio-apical tubercle. Hypophysis of style digitate, basal plate large and provided with numerous long hairs. Theca very large, globose. Spermathecal bulb (Fig. 84d) simple.’

Etymology. The new name is composed of the prefix Neo - (= new) and Dymantis; the gender is feminine.
