Smit, Harry, 2020, New records of the water mite genus Arrenurus Dugès, 1834 from South America (Acari: Hydrachnidia: Arrenuridae), with the description of five new species and one new subspecies, Acarologia 60 (2), pp. 371-389 : 377

Arrenurus (Arrenurus) soesilae Makan, 2005 – new syn.

Material examined— Argentina. Entre Ríos Province: 1/3/0, ditch at Brazo Largo, N of Zarate, 33°54’37,21” S, 58°51’9,24” W, 6-xi-1999. Surinam: 3/0/0, ditch along Weg naar de Peperpot, 5°46.857 N 55°08.327 W, alt. 3 m asl, 18-xi-2019.

Remarks — Arrenurus soesilae , known in the female sex only, is insufficiently described as the genital plates and the suture lines between the coxae are not illustrated. Nevertheless, based on the peculiar pointed posterior end of the idiosoma, it is clear that Makan (2005) illustrated the female of A. epimerosus . The female of the latter species is the only South American Arrenurus species known with such a pointed posterior idiosoma.

Distribution — Known from Brazil ( Marshall 1919, 1944, K. Viets 1936, 1954a,b), Argentina ( Rosso de Ferradas 1973), Paraguay (K.O. Viets & Böttger 1986) and Surinam (Makan 2005).
