Records of the Western Australian Museum 17:153-161 (1995). New species and records of cockroaches from Western Australia (Blattaria) Louis M. Roth Museum of Comparative Zoology, Harvard University, Cambridge, MA 02138, U.S.A. (Correspondence: 81 Brush Hill Road, P.O. Box 540, Sherborn, MA 01770, U.S.A.) Abstract - Three new species of cockroaches from Western Australia are described, namely Hensaussurea humphreysi (Blattellidae) and two cavernicolous taxa, Nocticola brooksi (Nocticolidae) and Neotemnopteryx wynnei (Blattellidae). A few new records of some Western Australian Blattidae: Polyzosteriinae, and Blattellidae are given. INTRODUCTION Nocticola brooksi sp. nov. This paper presents the results of a study of some Figures 1A-E cockroaches that were sent to me for identification by Dr W.F. Humphreys of the Western Australian Material Examined Museum. It was expanded to include a few All specimens were collected in caves in the specimens from other museums but I have northern Kimberley of Western Australia and in generally restricted the work to species found in the Northern Territory near Katherine.
