An Endoreticulatus species from Ocinara lida (Lepidoptera: Bombycidae) in Taiwan

A microsporidium from the Ficus pest, Ocinara lida, in Taiwan is characterized. The taxonomic position of this species was preliminarily determined by sequencing small subunit rRNA gene (SSUrRNA). Analysis of the SSUrRNA sequence indicated that this isolate from O. lida is a member of the genus Endoreticulatus and belongs to the genetic grouping containing other lepidopteran Endoreticulatus species we have analyzed phylogenetically. The taxonomic position of this isolate was also confirmed by the ultrastructural characteristics of this isolate. The congruence between SSUrRNA sequence analysis and ultrastructural characteristics shows that this isolate is more closely related to Endoreticulatus bombycis than to Endoreticulatus schubergi Zwölfer.
