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

Parachinavia prunasis can be distinguished from P. creolea by the longer rostrum, the narrower excavation of ventral rim of pygophore and the somewhat wider parameres, truncate at apex.
