(166NPdub) Neonaphorura duboscqi (Denis 1932)

*anglicana Bagnall 1936

Neonaphorura duboscqi is quite large for a member of the Subfamily Tullbergiinae. The longest specimen in the NHM is 1.4 mm in length and was collected by Bagnall in Torquay in 1936. The species is white, blind and possesses an elliptical post-antennal organ with about 10 granular lobes (Fig. 1). The most characteristic feature is the presence of SIX anal spines at the posterior end of the abdomen (Fig. 2).
     Neonaphorura duboscqi is a rare species but it is sure to turn up in many more sites with increased recording of species from soil cores.
