Genitalia as described for the genus. Comments. Dallas (1851) described this species in <i>Raphigaster</i>, subgenus <i>Nezara</i>, based on a female collected from Congo. Stål (1876) included <i>R. prunasis</i> in his ‘Inserti Pentatomidarum Loci Systematici’ list, while Kirkaldy (1909) expressed doubt as to its position within <i>Nezara</i>. Distant (1900) and Hesse (1926) listed the species in <i>Nezara</i>, and Linnavuori (1972, 1975, 1982a, 1982b) included it in <i>Acrosternum</i>. Schouteden (1909) described <i>Nezara conspersa</i> and <i>Nezara klugi</i>, and compared them to <i>Nezara miliaris</i> Klug. Linnavuori (1972) included all these species in <i>Acrosternum</i>, established <i>N. conspersa</i> as a junior synonymy of <i>A. prunasis</i>, and considered <i>A. klugi</i> as a subspecies of <i>A. prunasis</i>; he also compared <i>A. prunasis</i> with <i>A. millierei</i> (Mulsant &amp; Rey) and, according to him, the two differ mainly in the structure of male genitalia. In fact, this difference among <i>A. prunasis</i> and <i>Acrosternum</i> spp. corresponds to the diagnostic character proposed by Roche (1977) to establish <i>Parachinavia</i>. Linnavuori (1972) proposition of <i>A. prunasis klugi</i> was based just on head length; the variation observed in the specimens studied did not support this hypotheses. Therefore, <i>A. prunasis klugi</i> is synonymized with <i>P. prunasis</i> comb.nov. <i>Parachinavia prunasis</i> can be distinguished from <i>P. creolea</i> by the longer rostrum, the narrower excavation of ventral rim of pygophore and the somewhat wider parameres, truncate at apex.
