Etymology. The specific epithet of this new species is ‘ pseudoperta ’ as a combination of the Greek words ‘ pseudes ’ [= false] and the specific epithet of operta , a species described byRohÁčeKandMArShALL (1986) fromKorea.

Comments. RohÁčeKandMArShALL’s (1986) descriptionof T. (N.) operta isveryaccurate, whathelpsfurtherstudiesinthegenus. PAPP (2008 b) identifiedhis Nudopella specimensfromSouthAfricaincorrectly, usinglowmagnification. Acarefulstudyofthosespecimensrevealedthreedifferentspecies from Nudopella on material collected on dung of big hoofers in South Africa. These species occur together with N. erratica (see No. 33 of the RSA materials above). This, ofcourse, ischallengingforproperdiscriminationofthespecies, butreinforcestheconceptthattheyareseparatespecies. Themalesternite 5 in N. pseudoperta , sp. n. issomewhatlargerthaninitscongeners.
