Host range and habitat. Oligoxenous species inhabits quills of secondaries, tertrials, coverts, rectrices and is associated with sylviid birds of the genus Acrocephalus and Sylvia : Acrocephalus arundinaceus , A. dumetorum , A. paludicola , A. scirpaceus , Sylvia atricapilla , S. communis and S. curruca .

Distribution. Germany, Poland, Jordan, Russia and Kazakhstan.

Remarks. Comparision of the material from Sylvia communis (type host of Neoaulonastus bisetatus ) with the type material of N. scirpaceus Skoracki, 1999 indicated that N. scirpaceus syn. nov. is a junior synonym of N. bisetatus .
