03FF87E0FFBCFFA2FF17FD7EA1DA2F76.taxon	diagnosis	Diagnosis. Parastalius is the sister-group of a clade that includes Stalius (Campos & Grazia, 2006); characteristics of the general morphology and of genitalia distinguish these genera. Parastalius has better developed antennifer tubercles, and the anterolateral angles of its pronotum are produced laterad as spines rather than anteriorly as acute triangles as in Stalius. Another evident difference is the length of scutellum, which in Parastalius reaches the apex of the corium whereas in Stalius, it clearly surpasses the corium. The sinuous ventral rim, the processes on the genital cup, and the parameres (shape and direction) characterize the pygophore of Parastalius. The female genitalia of Parastalius have wider gonocoxites 8 with sinuous posterior margins not covering the base of laterotergites 9; and gonocoxites 9 are partially obscured by gonocoxites 8.	en	Matesco, Viviana Cauduro, Grazia, Jocélia, Campos, Luiz Alexandre (2007): Description of new genus and species of Ochlerini from Central America (Hemiptera: Pentatomidae: Discocephalinae) ¹.

The pygophore of P. rolstoni is subtrapezoidal and the parameres surpass the oval processes laterally. In P. trisinuatus the pygophore is subquadrangular and the parameres do not surpass the oval processes.	en	Matesco, Viviana Cauduro, Grazia, Jocélia, Campos, Luiz Alexandre (2007): Description of new genus and species of Ochlerini from Central America (Hemiptera: Pentatomidae: Discocephalinae) ¹.
