Introduction

This species was originally described from species of Cherax from Papua New Guinea, but has since been recorded from Australia. It is a well-known and widespread ectocommensal of crayfish in commercial aquaculture systems in Australia and overseas, however, D. boschmai is believed not to negatively impact on crayfish health. Jones & Lester (1993) demonstrated that D. boschmai had low specificity in cultured conditions, infecting a wide range of species of Cherax (C. cuspidatus, C. depressus, C. destructor, C. tenuimanus and C. quadricarinatus); it did not infect species of Macrobrachium because of the grooming habits of these shrimp. Grooming behaviour and host size were shown by Jones & Lester (1996) to influence population levels of D. boschmai on cultured crayfish.

Anatomy
Joffe et al. (1995) examined the syncytial epidermis of D. boschmai, collected from cultured Cherax quadricarinatus (von Marterns, 1868), using electron microscopy and found that the epidermis structure was different in different regions of the body, reflecting the different functionalities of these body regions.

Introduction

The name, Temnocephala simulator, was proposed by Haswell (1924) for a previously undescribed brown, six-tentacled temnocephalan, similar in anatomy to T. comes and in the development of spermatophores. The species was subsequently reassigned to Temnohaswellia.
