New Taxa of Loricate Euglenoids Strombomonas and Trachelomonas from Thailand

Abstract

Abstract Five new species and one new variety of loricate euglenoid taxa were discovered in Thailand: Strombomonas starmachii Duangjan & Wołowski, S. chiangmaiensis Duangjan, Trachelomonas peerapornpisalii Duangjan & Wołowski, T. thailandicus Duangjan & Wołowski, T. reticulato-spinifera Duangjan and T. hystrix var. paucispinosa Prowse. We propose to raise the variety to species level [T. paucispinosa (Prowse) Duangjan & Wołowski, stat. et comb. nov.]. The morphology and fine lorica ultrastructure of the species are described. All taxa are documented by SEM images and some by LM micrographs.
