Paratypes: (1 ♀): the same data but emerged from nest of C. alaudina , 23-IX-2009, ( JHAC); (1 ♀): the same data but emerged from nest of C. alaudina , 14- VII-2009, ( DIOC); (1 ♀): the same data but emerged from nest of Pseudoseisura lophotes, (DIOC) ; (1 ♀): Argentina, La Pampa, Paraje La Araña , 3-XI-2007, Turienzo & Di Iorio leg., emerged from nest of Myiopsitta monachus catita, (DIOC) .

Description.

Female. Body ( Figs. 6-7 ) measurements (mm): TL 2.5, EW 1.5; cuticle brown on dorsal surfaces, brown on ventral surfaces; in general small and oval, covered with brown and white recumbent setation. Head finely punctate, with white recumbent setation. Palpi entirely brown. Ocellus on front present. Antennae, brown, with 11 antennomeres, antennal club with 3 antennomeres ( Fig. 8 ), with light brown setation. Pronotum finely punctate like head, covered with brown and white recumbent setation; brown setation discally. Scutellum triangular, finely punctate as pronotum, without setation. Elytra finely punctate, on each humerus with a large bump; cuticle brown and orange, covered with brown and white setation. Each elytron with two orange, cuticular, transverse fasciae; fasciae covered with white setation, and with one small, apical white spot. Epipleura dark brown, finely punctate, covered with white setation. Mesosternum and metasternum covered with white setation; metasternum coarsely punctate. Abdominal ventrites finely punctate, covered with white, recumbent setation. Legs brown, with light brown setation; tibiae without short spines.

Male. Unknown.

Differential diagnosis. The genus contains three recently described species. The new species is very similar to S. brunnea Háva, 2014 ( Colombia) but differs from it by the following characters:

- white-grey setation forming two transverse fasciae on each elytron; elytral subbasal fascia not forming loop; pronotum not laterally dentate ( ColombiA) …………………………………… S. brunnea Háva, 2014

- white setation forming two transverse fasciae and an apical spot on each elytron; elytral subbasal FAsciA Forming loop; pronotum not lAterAlly dentAte ( ArgentinA) ……………………… S. argentinum sp. nov.

Variability. Paratype body measurements (mm): TL 2.4, EW 1.2.

Etymology. Toponymic, named after the country of its occurrence, Argentina.

Bionomy. The species was collected in birds ( Aves) nests of Coryphistera alaudina Burmeister, 1860 ( Furnariidae ), Pseudoseisura lophotes (Reichenbach, 1853) ( Furnariidae ) and Myiopsitta monachus catita (Jardine & Selby, 1830) (Psitaciidae).
