Шаблон:Short description Шаблон:Automatic taxobox
Blastocrithidia is a genus of parasitic flagellate protist belonging to the family Trypanosomatidae.[1] It is a monoxenous parasite of heteropteran insects,[2] mainly inhabiting their hindgut and glands.[3]
Characteristics
In addition to Blastocrithidia, one-host trypanosomatids from hemipteran and dipteran insects have been traditionally placed in genera Crithidia, Leptomonas, Herpetomonas, Rhynchoidomonas, and Wallaceina.[4][5] Blastocrithidia is characterized by epimastigote morphological forms, whereas opisthomastigotes and endomastigotes are exclusive features of the genera Herpetomonas and Wallaceina, respectively.[5] Blastocrithidia is also able to produce resistant cysts.[6]
Systematics
The etymology of the genus name Blastocrithidia derives from the two Ancient Greek words Шаблон:Wikt-lang (Шаблон:Grc-transl), meaning "sprout, scion, child or descendant", and Шаблон:Wikt-lang (Шаблон:Grc-transl), meaning "small grain of barley".[7][8]
The genus includes the following species.

Genomics
Genetic code
Blastocrithidia uses in its nuclear genome an alternative genetic code characterized by all three canonical stop codons reassigned to sense codons.[9]
