CAMINO, Nora B; RODRIGUEZ GIL, Sergio; REBOREDO, Guillermo R  and  GONZALEZ, Sandra E. Descripción morfológica y citogenética de una nueva especie de Parasitylenchus Micoletzky, 1922 (Tylenchida, Allantonematidae) parasitando Harmonia axyridis (Pallas, 1773) (Coleopera, Coccinellidae) en Argentina. Rev. peru biol. [online]. 2019, vol.26, n.1, pp.27-32. ISSN 1727-9933.  http://dx.doi.org/10.15381/rpb.v26i1.15907.

Parasitylenchus pseusobifurcatus sp.n. (Tylenchida, Allantonematidae) is described for the first time for Argentina as a parasite of adults of Harmonia axyridis (Pallas, 1773) (Coleopera, Coccinellidae). The new species is closed to P. bifurcatus Poinar Jr. & Steenberg, 2012, by the characteristic of having the tail tip of all vermiform females and immature males bifurcated, but they differ by the size of the gubernaculum. Its karyotype formula is described.

Keywords : Parasitylenchus pseusobifurcatus sp.n; Coccinellidae; morphometric; cytogenetic; taxonomy.
