Material Examined. HOLOTYPE fEMALE (336–HO–77), IN 70% ALCOHOL, LOANED bY THE HUNgARIAN NATURAL HISTORY MUSEUM AND 60 NON-TYPE SPECIMENS (12 ON SLIDES, WITH PART Of THE SPECIMENS DISSECTED AND MOUNTED IN HOYER’S, 18 ON ONE STUb AND 30 IN 70% ALCOHOL) COLLECTED ON 10–I–2008 AND 13 –VIII–2 0 13 bY ANIbAL R. OLIVEIRA fROM SOIL –LITTER INTERfACE SAMPLES IN A CACAO PLANTATION AT UNIVERSIDADE ESTADUAL DE SANTA CRUz (UESC) CAMPUS, ILHÉUS, BAHIA, BRAzIL, 14°47'49"S, 39°10'23"W. VOUCHER SPECIMENS IN 4 SLIDES, STUb AND 10 SPECIMENS IN ALCOHOL ARE DEPOSITED IN THE ACAROLOgICAL COLLECTION AT UESC. FOUR SLIDES AND 10 SPECIMENS IN ALCOHOL ARE IN THE ACAROLOgICAL COLLECTION AT THE ESCOLA SUPERIOR DE AgRICULTURA “LUIz DE QUEIROz” (ESALQ), UNIVERSIDADE DE SãO PAULO (USP), IN PIRACICAbA, SãO PAULO, BRAzIL.

Comments. EXAMINATION Of THE HOLOTYPE Of N. neotropicus ALLOWED US TO CONfIRM THE IDENTITY Of OUR OWN SPECIMENS, AND, THROUgH THE COLLECTIVE OPTICAL AND SCANNINg ELECTRON MICROSCOPY STUDIES, ALLOWED US TO CONSIDER CHARACTERS THAT WERE NOT PREVIOUSLY DISCUSSED. IT ALSO PERMITTED THE DETECTION Of AN ERROR IN THE ASSESSMENT Of THE OCTOTAXIC SYSTEM, WHICH COMPRISES THREE PAIRS Of POROSE AREAS. THESE STRUCTURES WERE NOT DESCRIbED OR ILLUSTRATED IN THE ORIgINAL PUbLICATION, AND BALOgH & BALOgH (1990A) SUbSEqUENTLY MENTIONED ONLY ONE PAIR.
